This question is regarding Ultra Group Assembled Front Housing & Thermostatic Cartridge - SNINASF

Temperature Problem 2

Thanks for you response. I have checked and the hot water supply is very hot so no problems there. However, I have isolation valves upstream of the shower and i thought I would try reducing the cold water flow using one of these valves. Even with a reduced cold water supply, the shower will still not go hot enough, and in fact if I shut off the cold water supply completely, nothing comes out of the shower! I would have thought that there should still have been hot water coming through? Any advice on what might be causing this? I am thinking of buying a new thermostat assembly and giving that a try???

Shutting the cold off completely and having no hot is afeature that many shower valves have built into them, the reason is that if thecold water fails then you won’t get scolded.

Sounds to me that you need to check the thermostat to see ifit needs replacing and fit a new front housing.

 

However first just to make sure everything else is OK youcould remove the front of the shower and give the hot and cold supplies a flushthrough.

See Below

This will take two!

 

If your valve is recessed pack an old poly bag round thevalve to divert the water into your Bath / shower tray then turn the hot andcold valves on one at a time and allow the water to flush through for about15>20 seconds.

 

The person who is helping you should watch that the wateris not going anywhere that is going to do any damage also they should watchthat the amount of water coming from the hot and cold they should be roughlythe same.
