My pressure relief valve opens, why? I have an American Std boiler Mod# GPMX8. My pressure valve was leaking and boiler was operating at 16psi. After replacing the pressure valve. I refilled boiler and was able to pressurize the system to 16psi. I turned on boiler and gas ignited and water heated to 190deg. Gas shuts off. Then pressure begins to slowly rise and will rise to 30psi. I did hear a strange buzz comming from the transformmer.

Hi ssam1

I'm Harvey the Master Plumber.

You want to know if you can fix a sudden low volume /pressure delivery problem on an American Standard model AS4205100 H7, one hole / single lever with pullout spray And is it fixable by owner?

Yes and maybe!

All plumbing systems are plauged with debrie buildup. Every time you turn on a faucet the water starts moving and will bring bits of debrie up from the water main or well. Most are small and will pass through to be caught by the screen in the aireator. Sometimes a relatively large piece comes along and dosen't make it through to the screen. It is stuck in the body of the valve.
Fixing takes a little mechanical ability.
First, turn off the water to the faucet in question. Then carefully disasemble paying close attention to the order of disasembly so you can reverse the order when putting back together. As each part is removed inspect it for that troublesome bit. I find that a little bit of wire or a paper clip is helpfull. Carefully reasemble. If the volume is still low then you missed finding that bit. Try again or call in a local pro.

Hi AaronYC,

I'm Harvey the Master Plumbe.

Your problem is: Installed a new American Standard Cadet 3 toilet bowl and tank at home. When you turn the water supply on, the tank refills normally and stops normally. After you flush, the refill is very slow. When it refills normally the water comes out from the bottom of the pipe (i.e. the pipe that houses the float cup) and when it is refilling slowly, it comes from the top of the pipe. Sometimes (but not always), you can shut the water supply off and when you turn it back on, the flow of water goes from slow to fast instantly - but you haven't been able to recreate this consistently.

These are the facts. American Standard has been keeping costs down by out sourceing. Their toilets are now built in third world countries and parts are made cheap. They're all doing it. Quality control is pretty good but your toilet came with a bad "ballcock". That's the refill part on the left. Because it's new, if you take the ball **** back to place of purchase they should give you new. If not, they cost less than $ 10.00 and easy to replace.

SOURCE: American Standard Cadet 2-handle tub & shower set-Model#3275 - low pressure output

When you installed the new tub faucet you probably turned off the water to that faucet of even the whole house. IF IT IS AN OLDER HOUSE, TURNING THE WATER OFF AND BACK ON CAN LOOSEN SOME DEBRIS IN THE WATER LINES THAT CAN FIND THEIR WAY TO YOUR NEW FAUCET. If there is a screen at the end of the water outlet it can be clogged with gunk. Uncrew the screen on the water outlet and clean. You may also want to flush out the hot and cold outlets by turning the water off, removing the cartigages and slowly let water flush them out. Then reassemble. Also when you have the tub handles out you can turn the hot and cold supply valves off and on a few times to loosen more debris if it exsists........Joe

SOURCE: Champion4 leaks water through flush valve

You have replaced the flush valve completely? If so and the unit is still leaking, you may have a small crack in the tank or your just not getting the tank to bowl fittings tight enough. Also, they make two different thicknesses in the tank to bowl gasket. Make sure you are using the thicker of the two. You posted this under the American Std. thread, so if this is correct, give them a call. There could be a recall on this particular toilet due to a flaw.

SOURCE: NEW American Standard shower installed... leaks from shower head.

They do not all leak. The problem may be that your faucet is simply wearing out and is due to be replaced in total. Try putting some plumbers grease on the cartridge and the chamber.....not too much..........that may do the trick for u.
