What would you like to do?
Most of the time its caused by lose pipe supports and no expansion tank or air chamber. Most fast closing solenoid valves will be the start of the problem. Copper pipes are usually the loudest and if you can see your pipes just shake them and use extra supports and it should go away, or add air chambers to all of your solenoid valves like dishwashers, fridges, washer machines etc.

What needs to be repaired when you have hot water getting into the cold water faucets of your house and is this caused by a failed shower mixing valve or just a failed gasket in the shower valve?
It depends on the valve, who makes it and what model is it? you have a cross connection in the water system ( I don't think it is the value, most of the time it is on your was…hing machine hot and cold water valve. Go to a faucet away from the machine and turn on the water. Then go listen at the machine you should hear water going through the hot and cold water valve of the machine, it is where your water hoses connect.) hope this helps If it is a new house and has always done it. It might be that they connected the hot and cold water together somewhere in the wall. You would need a plumber to find it. It is not easy to find though. Would most likely be having to open up a lot of holes in wall to find. Sometimes you will find it by trying fixtures one at a time. The one that gets hotter quicker is where it was tied in with the cold. Open up wall there. Then turn on water at the fixture and feel the pipes and the one that is hotest that is tied to cold would be the one you would have to change. You would have to take pipes apart and connect it back to the hot side. So you would be taking hot and cold apart so i would get plumber to do this. At least if you could find out where they were connected would save you a lot of money.
Answer I have worked in many jurisdictions that allowed PVC water service piping, but you need to check with the administrative authority that …enforces the plumbing code (if any) where you live. Answer Yes, most certainly. A recommended pipe would be HDPE Class 16 and size of your choice (i recommend either three quarter inch or one inch pipe for adequate pressure) In most countries, a main line has to be underground, however, as soon as the pipe exists the ground at any given point it has to be non-metallic. As stated above check with your council or municipality regarding any queries regarding what material is allowed and how it must be installed.
This is most likely to be water hammer. The most likely reason is because a pipe has not been held down properly with a pipe clamp. It normally happens when a toil…et is filling up or when taps are switched off suddenly. Its due to the water pressure in the pipes that makes the water rebound in the pipes causing them to rattle and make a noise
Really you should not do this yourself unless you are relatively experienced and have the proper tools. Shut off the water at the meter. Drain the pressure from the syst…em. Get the Outside diameter of the pipe on each side of the valve. You will need 2 pressure couplings and a new valve in between. You will need room to install your pressure couplings at least 2" of straight pipe on both sides of valve.
What causes a high pitched whistling sound to come from the water pipes near the water heater and and pressure valve when a tap is turned on?
Air causes the whistling noise. I'm currently on a quest to eliminate the problem in my house (just had new water heater installed about a month ago, sounds like a choir… of banshees when the water's running, toilets are flushed, washing machine or dishwasher are running,, etc.) When I figure out how to get the air out, I'll post a follow-up. In the meantime, at least you know what it is!
I believe it is due to the pressure build up within the pipes once the water is turned off. I know they sell a product that you place in one of your pipes that serves as… a buffer to stop the rattling.
Copper, Brass, Yellow Brass , Red Brass, Galvainzed steel, Galvanized wrought , Yalloy
After close main water valve in front yard.. If I do air pressure test from a cold water tab.. could it detect any water leak on hot water pipe.?
yes, as long as the cold water inlet valve to your water heater is open.
I have a normal tank water heater at home. After close main water valve in front yard.. If I do air leak test from a cold water tab. could it detect any water leak on hot wafer pipe.?
Yes. All the pipes are in the same loop. The water is just going through the water heater, but it is still just one system.
water heater problem, call a plumber. simply calling the plumber wont help, the plumber will ask these qustions, so be prepared before calling. Is the water temp coming ou…t? or do you have no water water coming out the tap. BIG DIFFERENCE!!! clues in the question, guru.........
if the pipes are warm or hot at the time the coldwater passes though them, it can cause the pipes to cool and contract
air gets in the pipes. If air gets "into the pipes" How come water doesn't come out of the same opening that allowed the air to enter?The main way air goes into the water… pipes is because of vacuum and there is many was to have a vacuum on a open non pressure line, because air is lighter then water it will always travel to the top of any fitting or pipe.
Usually the solid copper wire you see connecting to your water pipes is because it makes a ground for your electrical service of your home. Not seen as much of in newer homes …because most of the water lines including main water lines are mostly plastic type materials which electricity cannot flow through.
Not the geatest idea BUT check local codes CPVC is normally used for hot water applications and is highly toxic
I've never heard that in my house, but the pipes could be freezing or something.
