TMV question?

[jon26]

Does anyone know if there is normally a isolation valve on the cold supply to a TMV in order to close the cold supply and basically bypass the TMV so no mixing occurs. Even at its maximum setting, around 48degC, the hot water temperature is to low for the owner of the house. The mixing valve was fitted on the hot supply to a bathroom in a large house.

Cheers

there should be a valve yes
it sounds to me though that you don't need to isolate tmv rather by pass it all together

 

[dd1975]

if you just close valve
you will have no hw at all

So is there any way of stopping the cold 'mixing'. Is there a valve to allow this?

Why not just do away with the TMV
