FAO Tomplum

Got a multipoint heater prob Tom, can you help?

to be honest @art@,i'm not well up on multipoints, but if you give me a bell, numbers on my profile, i'll take a look and advice you.
if i can't fix it, i won't charge,

art,if for any reason tom cant fix it ,and your having to get another ,i have a mutipoint water heater which i had disconnected due to having a combi boiler fitted .its in perfect working order , well was before disconnection .im going to give this free providing who as it takes out and fills up where outside outlet goes .if tom can fix yours so and good ,for my email contact brian

A far as I can see, it's just the Diaphragm, which has gone.
Same thing happened years ago with the old one I had fitted at the time.
The present one isn't old enough to think about replacing.
Anyway, thanks to both of you..
