Re: SHOWER HOT WATER SCALDING
Hi as you are probably aware ,when the toilet is flushed the water pressure to the shower is reduced so you get hot/scalding water unfortunatly there is NO easy solution you could put a needle valve in the supply to the toilet and with trial and error by turning the valve down reach a compromise between the time it takes to fill the flushing tank and the shower temp the only real solution is to feed the toilet and shower off independent supplies but in most houses this is impractical if not impossible silk090

These types faucets have a what is called an anti scald valve build into them, it is required by law, it is either defective or out of adjustment, contact a local hardware store for more detailed info.
If I understand correctly, you have single handled shower faucet. Normally there is a wait for hot water to arrive at faucet. But now hot water is already at shower faucet.
Single handled faucets have a mixing area inside valve where hot and cold come together before going into sink. This mixing valve can have crossover where the hot and cold can pass through to each other even when faucet handle is off. When single handle faucets get old, this can happen. How it happens: For example another faucet is turned on inside house, and pressure differential between hot and cold causes hot water at shower handle to pass through mixing area and into cold water line. So if another faucet has been run, then that lets hot flow to faulty single handled shower faucet. To confirm this is the problem: turn on other faucet and put ear against shower faucet to listen for moving water. This condition may also signal there is a water leak. The problem is not harmful, but will draw cold water into water heater each time, and is energy wasteful. Replace faucet or have plumber repair problem.
probably have a kink on how water line feeding valve..if possible to cut drywall bhind tub valve and inspect pipe at bottom plate...moen faucets are equipped w/ anti scald device, pressure balanced (newer models) and this could cause cold water to overwhelm hot water...
check ur anti-scold setting when shipped from factory unit is set cold install instructions always advise about adjusting to suit your comfort--remove handle and using the blue & red adjustment tabs set the heat to your desired comfort
Remove the handle,and all the trim rings,and the cartridge cover. take a flat head screwdriver and use it to lift up the red ring behind everything, this is the hot limit safety stop, this just stops the handle from turning to full hot.
Once you have the red ring lifted up, notice the numbers and the pointer on the ring, numbers are on the fixture,
O= hottest 7=cold
See what the ring pointer is set to now, and move it half, before you put this back together, just set the handle on the unit and run the water to see if its to hot or not enough. Once you have found what is the best setting, then replace all covers and trim, handle.
This is a common problem with this type of shower mixer valve. They are not very good at regulating with pressure change. Your options are somewhat limited to not flushing the toilet or using any other taps when in use, repalce the mixer valve for a modern ceramic unit or installing a 2 vane hot & cold shower pump.
I always think I have heard it all at times and then a story like yours rolls in....Please call a plumber,I know what I am doing and you are not going to be able to solve this online. The faucet and toilets are never plumb together much less 2 areas as you have ...so please call a plumber this time...Please rate and this is not Inappropriate.Thanks jj505. Any other ?s please ask. Are you in Ga.30097
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
