is this the right place for TWIN thermostatic shower problems?

[Viper Gas]

Hi,

Simply put I have a customer complaining about her TWIN thermostatic shower and its inability to reduce the temperature of the hot water.

I thought it would be the cartridge or blockages within the filters but she mentioned that it was like that from day one, not sure if she is completely right about that. If she is could this be because of not enough cold water pressure from the CWSC.

Anyway any pointers in the right direction would be great.

Thanks

if it is hot when the shower is set to cold this indicates that from day one the pipes are crossed. simply swap the hot and cold feeds over and it should rectify it.

if it is run on a pumped hot supply and is too hot no matter what the setting try turning the pump down a notch or if not possible then restrict flow from the pump with an in line iso valve

thanks kindly for your pointers.

Are the pipes alwasy the same configuration, i.e hot on left and cold on right?

i would have thought so but you would need to consult the MI to be certain. is it pumped hot supply? if so that will probably be the culprit.

you mean a shower pump?

we always pipe hot to the left but many shower units are similar top and bottom and it does happen that they get fitted upside down unfortunatly the hot and cold markings are usually on the back

yes i mean a shower pump, or a pumped hot water supply for the whole house, either way if the hot water to the shower is pumped the first thing you should do is turn down the pump and observe. if pump can't be turned down then restrict the flow from the pump by an in line iso.
