Identify shower valve

[desmolift]

I need some help with a shower valve. The problem is, when the water pressure gets low due to a clogged water filter on the well and the use of water at another location in the house, the show valve turns on! Changing the water filter to a fresh one, fixes the problem temporarily. I'm thinking the cartridge is malfunctioning. This is a shower only, no tub, so the valve is only controlling the mix of hot/cold and on/off for the shower head. I have not been able to identify the manufacturer of the shower valve. Would anyone be able to help identify the valve and suggest a solution to the problem?

It’s most likely a Tempress 2 cartridge.

Many manufacturers used this cartridge so I’m not sure what actual brand faucet you have.

take the rest of the trim off.

I threw away about 15 trim kits just like that a few yrs ago. They were made by Grohe.

Not to drag this out... but.... when I look online for this cartridge I see many different manufacturers with prices ranging from $40-$140.

What would be the good replacement? I don't want cheap. I want quality.
