Hey, everybody. Im new here, just hoping to get a few perspectives on the issue Im having.
I have a stall shower with a Moen L2300 series Chateau single-handle temperature control. Also, I have a tankless water heater (brand/model can be found if needed). My goal is to be able to take cool to lukewarm showers when I want to.
Symptoms:
I can get very cold water, and I can get very hot water. When my single-handle faucet is in the 6:00 position, it is off. When it is in the 12:00 position (the midpoint based on the labeling of the unit), it gives me very warm/almost hot water as expected. For the hotter range (9:00 to 12:00), everything seems to be working fine. Between 12:00 and 3:00 is where my problem lies. Between 12:00 and roughly 3:00, there seems to be almost no change to water temperature. It maintains a very warm/almost hot temperature, no graduation to a cooler temperature as I would expect. At 3:00, there is an abrupt change in temperature it jumps to the cool/lukewarm temperature Im seeking and works fine for maybe a minute or so. Heres where it gets really weird the temperature then COMPLETELY bottoms out, and I cannot recover it to a warmer temperature at any point on the control, even in the hot range. It stays cold until I turn it off completely and start again, at which time it seems to act like Im turning it on for the first time which usually takes 60 seconds or so for hot water to arrive.
What Ive done so far (at Moens advice):
Changed out the original cartridge
Removed new cartridge and flushed pipes
Installed a third cartridge
At this point, Im questioning whether it may actually be an issue with my water heater. Ive been blaming Moen, but I also have other Moen faucets in the house (in sinks though) that seem to manage temperatures properly with a full range of temperatures.
Any suggestions or diagnoses?
