Shower valve hot water
After researching mixing valve problems on the web I had the cartridge
replaced in the Moen single handle shower valve to increase hot water. The hot water is known to be available by the sink next to shower where it is very hot. The new cartridge did not produce any more hot temperature than the old (2.5 years) one. Seeking a solution I removed the stop for the rotation to see if more hot water could be found. There was a burst of very hot water for a brief (.5sec) without changing handle and then a return to just warm water. This suggested that a thermostat was kicking in to prevent scalding when water is too hot. So I lowered the temperature from the tankless heater but it did not improve the condition. The research said these thermostats sometimes use wax pellets that control temps. Question..is the thermostat located in the cartridge? If not where would it be? Question…what other possible cause is preventing hot water reach shower head? thanks Bill |

Question…what other possible cause is preventing hot water reach shower head? thanks Bill It does sound like you have one of those safety valves that actively restricts the hot water. All mine simply have adjustable stops and I have adjusted them to be pretty hot. I saw a number of those safety ones on clearance at lowes the other day, they must not be very popular. A restriction in the piping is very unlikely unless you have a really old house. Cant you see any sort of model number or part number on the valve body? That would allow you to research it further. Otherwise I don't see any way to know for certain except to replace the entire valve. |

The valve will not make water hotter then what it is coming into the valve . The only thing you can control is the pressure balance and the Temp limit control which involves a couple of plastic rings under the handle which are probably set wrong . Suggest you read this section of the directions with the tap , also suggest you stop looking for a thermostat on the tap as there is not one . Only a limiter to control how far you can turn the handle to the hot side , as to not scald kids . Also check your pressure balance if it rattles it is good if not get it replaced . |

Number on black part of assembly is 109113 and was installed two and a half years ago. Adjusted plastic rings to max without change of temp. How is pressure balance checked? What rattles? The handle has to be turned counter clockwise from 12 to 3(max) to get hot water or warm water. That seems like the hot has to compete with an awful lot of cold water. I live in Florida and the water is not very cold. Your help is appreciated. Bill |
