I discovered that my Worcester Heatslave 20/25 boiler had a leaking Flow switch. I have been unable to obtain a replacement yet, but the plumb center advised me to try some pfte tape. I have tried this and while the leak is not as bad it still exists.
However, now my hot water is not firing up when I turn on a tap, it does fire up when I turn up the hot water temp on the front of the boiler. Should I just change the Flow Switch?
