Hello,
I have an issue where the resting pressure on my boiler is rising slowly over a number of days. I then have to drain some water out of a radiator to get the pressure back down. I have removed the filling loop but this did not solve the issue. So I reckon the plate heat exchanger is pinholed.
But are there any other ways water can cross from the HW side to the CH side?
I was thinking maybe the diverter valve, but I don't fully understand how that works.
So my question is can a diverter valve (faulty or not) allow a little water to cross from HW to CH or vice versa?
Thanks
