My experience has taught me that a piece of debris is clogging up a passage within the valve. If you have galvanized pipe a flake of rust is often the culprit. Another common source of foreign objects in a water system is off site construction and maintenance of the water delivery system. If you remove the valve from the valve body will find that the passages for the water that are in the casting are often as small as 1/8 of an inch in diameter. That is not enough to allow the water volume to force even a small obstruction out of the valve body.

What is the purpose of a thermostatic mixing valve?
The purpose of a thermostatic mixing valve is to mix hot water with cold water. This is what keeps the constant temperature in both bath and shower water.
How do you change a mixing valve in a faucet?
mixing valve in a faucet: ok I will assume you are refering to a shower valve, that is the only faucet w/a mixing valve: shut off the hot and cold water. cut out valve or unsweat it. clean and flux new valve, pipe and fittings(if used) sweat in new valve
How can you change a dual control bathtub faucet to single control with a mixing valve?
The incoming hot and cold lines go to separate inlets on the mixing valve. The single output will go to both the spigot and the shower head.
How do you keep shower temperature from changing when someone flushes the toilet or uses another sink?
Your water pressure is low. Consequently, when cold water is diverted to another application such as a toilet or a sink, the amount of cold water available at the shower mixing valve decreases as the low pressure is unable to keep up with the shower's demand. This causes a hotter mixture at the shower head. The solution is to either improve the cold water supply to the shower or to replace the shower control valve with a temperature compensating type. Pressure balancing is the cheapest and simply changes the shower temperature according to the pressure in the cold and hot water lines. When the toilet or sink is used, reduced pressure to the shower valve is detected and the valve reduces the hot water pressure, thereby maintaining the temperature. The more sophisticated approach is a thermostatic shower control valve. These are significantly more expensive, but will not reduce the pressure at the shower head (a drawback of the pressure balancing valve). The thermostatic valve would be required when one shower control valve is operating several shower heads. Moen, Kohler and Delta all make both types of control valves. They can be readily obtained from a local plumbing supply house.
What is the name of a device that equalizes hot and cold water flow to prevent temperature fluctuations?
It is called a pressure balancing valve, usually used in shower applications. Also a preset temperature mixing valve could be used depending upon what you need the device to do.
What does a stop check valve in a shower do?
It stops by passing of cold into hot and visa vera
How do you install the cpvc plumbing on the round single shower handles that twist in a circle?
On the back of the valve/diverter there are either four or three openings. One on either side for hot and cold water coming into the valve and one on top going up to the shower arm. If it is there the fourth opening is on the bottom and would go to the tub spout. Depending on the design you may have to solder adapters for the cpvc fittings into the openings of the valve.
What causes your Temptrol shower valve to vibrate when turning the valve slowly from cold to hot?
pressure regulator valve gone bad . stem problem or seats in faucet
Is the water closet for cold water only?
No, you can install mixing valve that will give you tempered water to toilet.
Why is no water coming from hot water heater?
The inlet valve is shut off on the cold water feed side or your mixing valve or tempering (if you have one has failed.
Which is healthiear a cold shower or a hot shower?
a cold shower
Why do you have to turn on cold water first to get hot water to work in shower?
On single handle shower valves, designed to let cold water first and turn handle farther to mix hot water to desired setting. If hot water turned on first, possibility of getting scalded. If seperate hot/cold handles for shower, shower valve needs work.
