Master bathroom shower valve was replaced 3 years ago during a partial remodel. Valve used was a Moentrol 3520.
I no longer remember the timeline, but for as long as I can remember, it takes 5-10 mins of runtime for the water to reach the desired temp.
Yesterday, the water did not get warm despite being on for 10-15 mins, so I turned the handle to the “maximum hot” setting. The water immediately became scalding hot. At that point, I turned the handle back to warm…yet the water remained scalding hot. So I turned the handle back to “maximum cold”…water remained scalding hot.
I went ahead and replaced the shower cartridge - no change in behavior. For reference, the cartridge is a Moen 1225 (12801).
Any direction is appreciated. Thanks.
