Hi,
We have a thermal store and a powermax blending valve.
The hot water has become a trickle (although it is still hot if I adjust the valve). The CH etc works fine. I believe it is a P757 blending valve, do you think this would be the issue? Cold water pressure if fine.
It's £100 so I want to be sure before I buy it . Or is there some maintenance I could do?
Thanks,
Paul.
Edit:
Searched again and found references to descaling the valve. If I try this how long should I leave it?
Also, while I have it off (so to say ), can I descale the coil in the thermal store? If so, how would I go about it? Just pour some desclaler down the pipe going into the store?
