[Chrisneedshelp]

Hi, Can some one help me out please, all of a sudden our hot water is not as hot, it seems to be running a little faster than usual, I have read all my manuals etc, and have dismantalled the pressure differential valve (DHW), to find a small hole in the diaphram, is this my problem?, im not Corgi reg'd so can i buy one and where, or alternativly I am in Poole Dorset, if anyone is local?, thanks in advance, Chris

You dont need to be CORGI registered to work on the wet side of your boiler.

You need to find a boiler or heating spares stockist. If you got really stuck I could post one but you will probably find one somewhere locally in the Yellow Pages.

Common after 10 years devided by the number of people living there, roughly!

The "system flow" diaghragm is used in any boiler function. They rarely fail so dont bother to change it and in any case that involves draining the system water from the boiler.
