baxi 105e pressure

[nigelkili]

Im still battling with pressure issues...each time i top it up it works for a few hours - but on other times - like last night - it lasted 14 hours with no top up...
why would it go for longer periods on some occasions than others ?

i have seen many posts here about the same issue - with losing pressure - is it somemthing that you can replace yourself if its a standard part ?

Try recharching your exp vessel first tho. Do a search on here to see how
