Hey all
I fitted a cheapy thermostatic mixer shower/tap to the bath that's been working fine for the last two years.
Similar to this one. LINK
Last week the shower was only coming out lukewarm.
I tested some other taps in the house to make sure it wasn't a problem with the boiler and water is running red hot every where else.
Today I took the Valve cartridge out of the mixer tap to see if it was full of limescale.
Surprisingly it looked okay. I gave it a good wash and lots of black deposits came out of it.
Not entirely sure what they are, like small bits of grit but not sure if metal or not.
I soaked the valve cartridge in limescale remover to be sure and re-fitted it.
It doesn't seem to have made much difference.
There is also a thermostatic mixing valve under the bath in the most awkward position possible.
It's already set to the hottest setting.
I'm not sure if there is a problem with the tap valve cartridge or with the TMV under the bath.
Hoping it's the tap valve as the TMV is a nightmare to get to.
Also the tap valve is only a tenner.
So question is should I just replace the tap valve for a new one and see if that solves the issue.
Is there any thing else I should be checking?
If not and it turns out to be the TMV can I just remove it completely and run the hot and cold feeds directly into the tap?
The TMV under the bath is a pain in the arse any way.
photo for context.
Space is extremely limited. I can't even get my hand to the left side of the TMV.
