britony combi se 3 way valve leaking

[ollieskint]

Hello - i just moved into house with this combi boiler and it started leaking and losing presure when i turned it on! Pressure goes up and down and then leaks and drops pressure completly...

ive read other posts about similar probs but when i looked at our combi it looks to me as though its leaking from number 17 on the instruction picture page 4. which is the 3 way valve so instructions say???

Any ideas how i can fix this leak myself or do i need an expert/bigger morgage???

Thanks for any advise...

think every plastic part of a chaff will leak eventually. very poor boiler.not very costly parts though.personally id rip the thing out. but not hard to change.is it the 80 your on about by any chance.
