Diverter valve issue

[smithk77]

It was a new one I believe, I took the diaphragm out and this was new but like you said unsure how long it's been sat around.

Thanks for the silicone advice I think I've got some in the garage from a previous job so I'll give it a blast, last chance saloon before a new purchase.

What are half decent boilers out there without breaking the bank.?

Don't touch gas, I'm a competent diy person, trained as an electrician but know my limits.

I can't really comment as I am a DIYer, but most of the RGI's on here seem to recommend Worcester or Vaillant. Avoid Ferroli like the plague.

Bear in mind that any new boiler will need to have the condensate pipe run to a drain somewhere, either an internal waste pipe or a gully outside.

Sorry I have to impart to people not to touch gas carrying parts, there are too many people who just wade in without a clue, and it's difficult to judge levels of competence from behind a computer screen.

Your diverter was originally made by Giannoni, who made em for Worcester and many others.
A new boiler would use less gas, and after 10 years you'd have your money back, then you'd need another boiler anyway..
No reason you can't change these wet bits, if you get something wrong, you just get wet really, or it all stops when you spray the pcb.
It's horribly easy to put the diaphragm in the wrong way round.
If it's leaking from the holes round the "waist" then a gland is leaking and will have to be changed.
I had one new Halstead diaphragm last an entire WEEK!
If it says MUT on the DV it's a compatible rather than original. I remember one which was 1mm too long to go in a Quattro. (It was an Indian Restaurant in Wembley, at least I got fed...)
If it's a Banico, then - do you feel lucky? At one time they were dire.
A NEW diaphragm shouldn't be stretched, but a used one might only LOOK ok.
Then there's the things I've forgotten..

And there we have the things that us DIYers never get to know about.
