What is normal house water pressure?
The range of normal residential water pressure is from 30 to 80 psi. Ideally, the pressure should be set between 45 and 60 pounds in most residential plumbing systems.If the pressure rises too high particularly above 80 psi, plumbing fixtures and appliances (primarily water heaters) could be damaged or leak excessively.

Is it normal to have air in the return lines if the pipe pressure is OK and the skimmers are full of water?
I think it could be normal, if the pool is not losing water.. On my filter and pump, I have a valve, that when open, causes bubbles to come out of the low end jets, simulating the jets of a jacuzzi. When closed, there are no bubbles.. If the pool is losing water, then the appearance of bubbles in …the pump, or coming out of the jets could be due to air from from the outside which would mean a leak in one or more of the lines or at the fittings.. Also, I'm curious as to how one would "pressure check" a return line from the skimmer, the main drain or vacuum line since these wouldn't be under pressure from the pump.. Answer . If your pool is blowing air back into the pool through the return lines, it is caused by an air leak, on the suction side of the pump. Because the pump is above the water level of the pool, you will not lose any water. To check to see if you are sucking air at the pump, turn the pump on and take some dish detergent and squirt it along each plumbing fitting in front of the pump. Watch to see if any soap bubbles form in the pump housing. If so, you'll probably need to to replace those fittings, one of them is leaking. ANSWER:: The leak discussed above could involve both in and out fittings on the pump or it could be a leaking pump seal or a loose pump lid or lid gasket. The probable cause of this leak at the fittings is that the pump ran dry at some point in time causing the PVC fittings to become hot and shrink. . Pressure testing of the return lines involves plugging those lines at the pool and and pump. The people who do this sort of thing have a tool or tools to insert in the system and introducing air into those lines monitoring pressure loss in each particular line through a process of elimination.

How do you fix a shower that has no hot water pressure when there is hot water pressure everywhere else in the house?
Replace the shower valve (faucet). I would call a plumber to check it out. Because there may be another reason, it depends on other things besides faucet. Like a crimped water line under slab floor, if you have copper water lines, i have seen the cooper pipe go all the way into a tee and block off …the outlet to the faucet. If it has been like i have mentioned above it would have been like this since day one. It would help if people would tell how old there house is and how long has the problem been going on. And yes it could be very much the faucet itself if it just starting do it. IN ADDITION: This also depends if the shower has a mixer or tap (faucet) installed, as the question didnt stipulate this. The rest of the house could have taps and the shower have a mixer. Mixers need a minimum pressure of 400 kpa from the hot water tank (geyser) to work. If the hot water tank is of a lower pressure this would explain for its poor performance. (MORE)
Is there a problem with the hot water tank if there is no hot water pressure throughout the house but the cold water pressure is fine?
Answer . The water shut-off valve on the cold inlet pipe above the water heater could be partially plugged with debris.\n. \nTurn off the main water supply shutoff to home and take the valve apart to clean.\n. \nJR\n.
simple, you increase the height of the storage tank thus increasing the water head pressure to the cylinder or install a continuous rated pump (but not recommend) for best results change the cylinder to an unvented (output: potentially 22ltrs at 3 bar) :o)
Depending if your on a well or public water system ,Well sys just increase your pressure with your pressure switch ,adjustment of your pressure regulator valve if so equiped (turn in )clockwise Plumbers generally apply a narrow vent in the tubular flow of your plumbing pipes to increase the water …pressure. If the flow is divergent one, you may use a water knob or a valve to enhance the water pressure. (MORE)
get a water pump and hook it up after the water meter. the only other way would be running 3/4 water line from the meter than reducing it to 1/2 inch water line before it reaches the tub or sink.that would help with some pressure,but it will not be a drastic change, buying a water pump would be the …best idea if you want a big differance. Ans 2 - 50 psi is quite adequate normally. You must have blockages somewhere inside. Possibly in the aerators, the stop valves under sink and toilet and in the water heater. -At least investigate these first- it may save you a lot of money. (MORE)
Answer . \npoor water pressure from your city. Or if you are on a well, the pump might be going bad.
What could be the problem in a 2-story 3-year-old house in which the water pressure varies from all outlets varying from none to almost normal?
Answer . \nStart out by checking faucet aerators and shower head restrictors/strainers. After that you may want to get plumber to take a look at your piping.
The water pressure in my house is about 140PSI. Which is definitely dangerous. It happens more often than you would think. What happens is a city will use water supply lines which are too small for the water requirements. Therefore, they have to increase the pressure. You wouldn't want a pressure re…lief valve, because then if the pressure was too high, it would just spray water everywhere to release the pressure. You would want a pressure regulator installed, which is what I am working on for my house right now. Just to let you know though, you may have to get a thermal expansion tank for your water heater if you don't have one. See, the new pressure regulators have a check valve in them, which prevents water from traveling back into the city pipes once it has gotten into your house. When your water heater heats the water, the air bubbles in it expand, which increases the water pressure, and will probably cause your pressure relief valve on your water heater to blow. You can get a cheap water pressure meter at any improvement store to check it out. 50-60 PSI is ok. I would say you could take it up to 70 or 80 PSI safely. (MORE)
Answer Typically it's because of restricted flow, either from small pipes or from excessive mineral buildup on the inside of the pipes. I honestly do NOT believe that water pressure "drops throughout the house" -How do you know that, have you measured it with a gauge at each faucet, or are you ass…uming. . (MORE)
Answer . No. Close off the main at the tank and add air (around 35 psi).
Answer . It's more than likely that you have something stuck in the screen of your faucet or there is something stuck in the valves under your sink, best to shut off your main water and clean them out, and unscrew the the cap on the end of your faucet and check the screen. Hope it helps. . than…ks, but.. I checked the screen and it's ok.. also I added a new sprayer onto the unit, every since then the water has been running slow (MORE)
Answer . I Guess the easiest way would to buy a gauge place it on a hose bib connection and then read what the gauge pressure is
There is no such thing as normal water pressure, it is changing all the time due to demand in the water distribution system. If a PRV is needed then the pressure is higher upstream than is wanted.
Check the inlet valve to H/W tank. make sure it's full on. If still no hot water anywhere you need to call a plumber, you have a weird problem.
There is usually a main water valve that comes into the house, locate this valve and turn it down. Installing a pressure reducing valve after water main valve will allow for adjustment of water pressure to proper setting.
Depends on the fixture demand and the height and the velocity and of course if your feeding a hydronic boiler then 12 -15 PSI is the average
How to reduce your water pressure to your taps if you have a high mains pressure or an unvented cylinder such as a megaflow, boilermate ect. Reducing water pressure in your home can be done in several ways, my video demonstrates a few. Some people turn down the isolation valves or main stopcock wh…ich is not advisable, as it can produce noise, water hammer in pipes /taps and can damage the valves and stopcock. (MORE)
"look at the little thermometer" Whoever posted that answer should be blocked from answering questions. A thermometer measures temperature, not pressure. Most hardware stores will have water pressure gauges, they can be purchased for around $10.00 and may have garden hose threads or standard pip…e threads of various sizes. You may have to adapt to attach to something near where you want to measure pressure. If you attach to a hose spigot, remember that pressure is lost from the moment it enters your home until it reaches an outlet. There is friction in piping and pressure loss due to elevation. Try to measure at something as close to where the water comes in to the home, not at a line far away where it is exiting. When testing the pressure one must do the following 1- With a gauge you test the pressure with no flow to give the incoming available pressure 2- Open a tap and watch for a pressure drop, which can be quite severe with ferrous metal piping 3- Then you take the pressure and times it by 2.31 that will give you the height the pressure will elevate the water For example you have 40 PSI will elevate the water to 92.4 ft to prove it you take 94.4 feet and times that by .433 The friction losses are not that much of a concern if your not working on a high rise building or long developed lenght of piping and fittings non ferrous metal piping or plastic offer the least amount of friction losses What is a concern is the velocity which if unchecked can cause piping erosion and hydraulic shock (water hammer) A hydronic boiler gauge is a great tool as it is a tri-indicator giving static pressure , and actual operating pressure as hot water gets heated it expands increasing the pressure thus incoming pressure can be raised considerable when heated (MORE)
Check the H/W tank and possibly clean it out: - You first turn OFF the power to tank, then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, turn OFF your inlet valve and open the relief valve so air can enter the H/W tank.Let the whole tank empty -…takes about 30 -40 minutes. Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, then turn on power. (MORE)
Home water pressure in a 2 story on city water with all valves closed is 107psi. Open any faucet and the pressure drops to 50psi. Is this normal and why is there such a discrepancy in pressure?
107 is too high, 50-75 is perfect. You should have a Pressure Reducing Valve on the supply to the place to make sure the pressure does not exceed 75 PSI. The reason is it wears out the parts on all your faucets a heck of a lot quicker. 107 PSI is also NOT very good for your hot water tank. The expan…sion and contraction of the hot water tank due to the pressure fluctuations and the undue stress on the Temperature and Pressure relief valve on the Hot Water Tank could cause you MAJOR problems in the future. PRV is needed. (MORE)
There are many cause of this, but the primary reasons are in the pressure tank. The tank MUST have residual air pressure of around 27 psi to drive the water system. To analyse further I need to know what kind of tank you have and what air pressure is in it when the water ceases to flow. I need to kn…ow what pressure your pump starts and if the tank feels heavy (full of water) when the pressure is low. (MORE)
You first need to check the tank air pressure. This is done at a nipple a bit like a bicycle tire nipple, usually near the top of the tank. check with an ordinary tire pressure gauge. -If less than 25psi, you need to re-charge the air. This is best done by a well technician (not a plumber) who under…stands the ways to charge different tanks. A well tech can also check the pressure switch, control box and pump from the surface. - Many problems can cause this, and if you have no knowledge of well systems the best way is to call a well tech. (some plumbers, but by no means all understand wells) (MORE)
Two ways, depending if you are on Municipal or your own well. If on Muni supply then there should be a Pressure Regulating Valve somewhere near where the main supply pipe enters your home. This can be adjusted easily and there should be instructions hanging right on it. If you are on a well, there… may be a problem with your pressure tank. This tank where the water enters from the pump is a critical part of your system . It should have an 'air charge' of approximately 27-28 psi. If this air charge has gone down, then your water pressure will be lower. If this tank is very old, possibly silver or green in color, then it's a "galv tank' and is possibly 'waterlogged'. This means you have to recharge the air with a compressor (just like blowing up an auto tire) To do this,switch off the pump. Open a faucet near the tank and let most of the water out. When you think it's nearly empty, close the valve to house and pump in with the compressor till the needle on your tank gauge points to 27. Now switch on the pump and the pressure should be improved. -IF your tank is a pale blue one, then chances are it's a 'bladder' tank and low pressure means your bladder is leaking. -You can pump it just as I said already, but in this case it will only last 2-3 months. You basically need a new tank. (MORE)
Pump broken, even if it seems to be running, OR, pump needs "priming" (get water into the pump since it will not suck air), OR something is blocking the water from exiting the pipe (ie, back pressure, as if "destination is already full") OR there is no water feeding the pump. OR, maybe the other sid…e of the pipe is leaking, hence no "pressure" (MORE)
Why do I have only one water faucet in my house with slow running hot water although the water water is pressure is strong?
Perhaps the filter screen is blocked, which you can clean and replace. This may improve the flow through that faucet.
Check your water heater to ensure that the valve in the supply line is open. You can test that the water heater is working by using the relief valve at the top, just beware of the potential for scalding hot water to come out if the heater is operating correctly. If you have a full tank, and all the …valves are open around the water heater, it may be time to call a plumber. (MORE)
There may be a number of causes. First, check your PRV and see if you can adjust it to higher pressure. This is usually easy and may solve your problem. If new construction has gone up nearby, mains pressure may be lower. Also remove and clean all aerators and see if that makes a difference. Many pe…ople totally ignore this basic step. (MORE)
get a measurable volume device like a bucket, turn your tap on full, place bucket under tap and time out 30 sec. measure volume of water, double the volume and you have your flow rate per minute. from there you can work out your kpa but i am unaware of the formula right now and cant help any further…, my apologies (MORE)
An obstruction, excessive demand, high temperatures that could expand the pipes (in this case, given a constant water pressure, the velocity of the water is slowed as the diameter of the pipes increase)
They would if not for the use of motorized pumps, that push the water to the upper levels.
Codes vary, check max. press. allowed in home, if press. higher than allowed by code coming into home, than install pressure red. valve.
the water company - if you look on their website it should tell you what the minimum water pressure you should expect is. You can test this by timing how long it takes to fill a certain size bucket. This is only cold water. The hot water pressure will depend on your boiler and should not be reported… to the water company. There is more to this Yes the water company states what the min pressure should be in some cases as low as 8 PSI but before you start doing the bucket measurement one has to know the size of their pipe as each diameter will give a different flow rate and also what material your water main is as many ferrous mains do have a severe build up of mineral deposits which also affects flow rates . Also some mains do get "crushed" over the years if proper compacting is not used to insure the main is not bearing to much weight (MORE)
you can improve water pressure by installing a booster pump or if on a well then turn up your set pressure. If you had good pressure before and now are having poor pressure then it could be many reasons.
If you are on a well it means you have a problem in the pressure tank. On city water means pressure in general is down, or your PRV is failing.
YES, as a hot water tank should NOT have a relief valve it should have a combination of Temperature and Pressure relief valve. Normally a T&P is SET @150 PSI and Or 210 Deg F. If the valve leaks this is a sign of an impending disaster such as a pressure vessel exploding. A professional will check… to make sure (NBBI, ASME, LMP,) 1- The pressure is not exceeding the high limits of the system 2- Make sure the aqua stat is actually functioning 3- The pressure temperature relationship of the system is not exceeded (MORE)
10-15 pounds per square inch typically. How high above your taps is the surface of the water in your roof tank? Use centimetres. Then the weight of water pressing on your downstairs taps is that height, in units of grams per square cm. Convert it to pounds per square inch if you like. 1psi is 454gm/…2.54 2 cm 2 =70.4gm/cm 2 .

If it's a bladder tank, it should always have "Air" pressure but if the pump isn't working, you still wouldn't have water in the house.
Inside pressure is warm and outside is cold. But any where outsidemy house there is no problem. Urine becomes normal and no problem
A liquid boils at a temperature at which its vapor pressure becomes equal to the pressure above its surface. Since you have increased the pressure to higher than normal atmospheric pressure, the water will not boil at 100 o C, this is because the vapor pressure of the water at 100 o C is now lower t…han the atmospheric pressure above the water's surface. In order for the water to boil its vapor pressure must be increased to at least the higher atmopsheric pressure. To do that you need to increase the temperature of the water since vapor pressure increases as the temperature of the water increases. This is why water will boil higher than 100 o C at a higher than normal atmospheric pressure. (MORE)
Low pressure coming into the house. Pressure regulator on the line where it enters the house. Old pipes full of buildup. Screens on faucets clogged.
If you are on city water, a large pipe has burst somewhere causing pressure to drop drastically.

Many well heads (at least… in my area) are very inadequately protected. (MORE)
The aerator at the end of the spout needs to be unscrewed and the screen and/or water saver cleaned out. Before rescrewing the aerator back on, run the faucet and see if you have full pressure. If not, the spout itself sometimes gets plugged too.
Usually the bib nearest inlet like front garden hose bib will give you a good read before it is reduced by any other valves etc. or spit off into a series of different pipes.
1) Clogged up lines from sedimentary/hard water build up. 2) Loss of air pressure through relief valve or the air volume control. To fix 1, you need to drain tank and clean it and that's just from what I've read. To fix 2, you need to tighten relief valve, but not to tight as you do need some air to… escape as your tank fills with water. Air volume control is what I'm having to replace now, it's about a $25 part. (MORE)
yes. loosen the locking nut, adjust the screw / bolt down to increase psi, out to decrease psi.
What causes high water pressure in the first faucet on the water line from where it enters the house. The cold water is under high pressure but other faucets in house are fine.?
Possibly a pressure reducing valve installed after piping for first faucet, which would cause situation describing.
yes and no. usually you want your psi between 65 and 80. otherwise it will cause you problems!!
Why is there Low hot water pressure to shower and sinks throughout house cold water pressure is good?
There can be number of reasons for this. The valve to H/W tank is possibly not totally open, the tank could be 'sludged ' up if you have not cleaned it for a while. H/W tanks should be cleaned every 3-4 years. You first turn OFF the power to tank, now remove the anode rod, ( a large bolt head on t…op of the tank, attached to what may remain of your rod) . then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, turn OFF your inlet valve and open the relief valve so air can enter the H/W tank. Let the whole tank empty -takes about 30 -40 minutes. Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, and fit new anode rod as it fills ( weight of the water helps) then turn on power when full. (MORE)
