air pressure should be around 3 lbs, on air bladder,
water pressure should be around 60 lb or depending on how far it has to push it, mine is at 80 lb on my well
also make shure the shut off switch is rated for your settings, they come in diffrent settings, low side and high side,

∙ 11y agoThis 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 the pressure switch is a standard 30/50 switch. (see note below about 40/60) 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 "galvanised 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, 28 psi. 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.
In all cases check the size of the pressure switch. It's printed somewhere on it . 30/50 as I've mentioned is common but some are 40/60. In this case pump in 38 psi of air. Both pressure switches are adjustable to a small degree by turning the central spring up or down. It's essential that lower limit of this switch is 2-3 psi above residual air pressure.
Always use a good round tire pressure gauge, (available in auto stores for about $5.) to check tank air pressure, Don't rely on the installed gauge, they soon get erratic.

Your badder tank kicks on at 25 lbs what should be the air pressure in the tank?
The pressure in your tank should be checked with water drained from the tank, with the water drained the air pressure in the tank should be set 2psi lower than your kick in pressure. So for a kick in pressure of 25psi the tank air pressure should be set at 23psi.Ans 2 - Water should NOT be totally drained from the tank or you may get a false reading ! - Leave 2-3 gallons in the tank. Most systems have the pressure switch set at 30 Psi, so tank residual pressure should be 28psi. - Lower than this gives really dismal pressure in the shower, especially if it's on second floor.
What air pressure is there in a pressure tank In a hot water heating system what should the pressure in the tank be?
A hot water heating systems water pressure should be 12-25 psi , the air in the expansion tank should be set around 10 psi but can only be accurately tested with no water pressure against it. Usually u can tell if the tank is bad when the relief valve on the boiler starts releasing water
How do Air compressor auto on-off switches work?
They are based on the air pressure within the tank. They come on then the pressure drops to a pre-set point and shut off the pressure raises to a pre-set point.
When you want to set up a water tank why do you put it higher than your house?
because the water flows much faster this way and the water pressure is high
How hot can the water get in a tank set on high?
It can get to almost boiling if your relief valve doesn't work.
How do you pressurize your water system with a well mate pressure tank?
The tank comes with a residual air pressure of about 40 PSI. This can be regulated through the air nipple at top of tank. If you are going to use 30/50 as is common, then set tank air to 28 by adding or letting air out of this nipple while the tank is empty of water. After setting this pressure, adjust the pressure switch to come ON at 2 psi above this , ie 30 PSI. Now when the water level lowers in the bladder the pump will switch ON before the tank is empty. If tank residual pressure is very low on an old tank it is possible that your bladder has holes.
Will a new water pump increase water pressure?
It's more a function of the pressure tank and pressure switch. -These MUST be set up properly. A badly adjusted or worn pump will still put water in the tank, just at a slower rate. -Any pump should put at least 5 gallons per minute in the tank, or it is ready to be renewed. Most low pressure in house is caused by low air pressure in the tank. You need a well technician to check this system - NOT a plumber.
If deep well pressure isfrom 48 to 68 lbswhat should the air tank pressure be set at?
Generally the pressure in the tank air bladder should be 2 psi below the water pressure switch kick in (pump turn on) point. In this example of 48 to 68 Lbs the air bladder pressure should be 46 psi. This pressure should be measured with the tank empty of water, that is to say NO water pressure applied. NEVER over pressurize the air bladder - it would be better to under pressurize if in doubt. Some tank manufacturers may recommend a different PSI differential so check with the tank literature or the manufacturer.
How can you improve your well water pressure?
Well pumps have a pressure operated switch that turns the pump on at low pressure (maybe 20 psi) and off at high pressure (maybe 60 psi) The tank that stores the well water and supplies the appliances with water when the pump is off has a bladder inside it that needs to be charged with air (assuming a newer tank) check the tank for a "tire" valve with a recommeded pressure to charge the tank with (usually a stick on tag). Use a tire pressure gauge to check the bladder pressure. To do this shut off the pump. Run water until it stops from a faucet. Check and correct the pressure. Restart pump. Making sure the pump tank is properly set up will probably help your pressure problems.
You replaced the pressure tank so how do you find out what the pressure switch is set for so that I can adjust the air in the bladder?
Install a gauge in the plumbing. Usually 1/4" pipe thread. Or you can use a tire gauge and check the pressures on the Schrader valve on the tank. With the Pump on, you will be reading system pressure. With the pump off and all water pressure released from the system, you are reading tank pressure.
What would make the water pressure in a house go above 80 psi?
Area water authority could have increased water main pressure, no or defective expansion tank in house main water line if house has a backflow preventer installed, or defective /not properly set pressure reducing valve.
How do you replace a expansion tank on a boiler system?
Turn off the makeup water and electrical service to the boiler. Isolate any and all valves in the system. Thread the old tank off, thread tape and/ or thread sealant on male ends of new tank and thread it in. Bleed air from system as needed using makeup water. Dependent on the piping arangement, if the tank screws in the bottom of an air scoop, an air eliminator atop the scoop may be removed and then replaced after all air is purged. Note: in using makeup water valve/ bypass, do not go over 30# of pressure. Most residential boilers will have a safety relief valve that is set at 30# that will blow off at this pressure and make a mess. The makeup water pressure reducing valves are generaly set to maintain 12# of pressure. Most pressure tanks are precharged at the same 12# of pressure on the air side. Verify these pressures and that all air has been purged from the boiler and pumps, before refiring the boiler. lc
