Re: Header Tank Overflowing with Warm Water
Sure, the water in the CWS is much higher than the f/e.
Okay. I will isolate both hot and cold feeds to the shower tonight and put the cold mains feed to the house back on. As you say, if the cws doesn't start to fill up again, it must be that. The shower is a thermostatic mixer and it's only around 3 years old so I didn't think this would be the problem, but I'll definitely check it out, and do the same for the other two mixer taps.
One other thing you reminded me about when talking about balancing the pressure, I did fit a valve on the cold feed into the house that allows you to adjust down the pressure of the cold water. I did this to try and balance the cold and hot feeds a bit better to help the operation of the thermostatic mixer shower. Maybe I should try and tweak that a little to drop the cold feed pressure...?
Will post back tonight on what I find out anyway...
Cheers!
