Alpha CB24 pressure release pipe leaking slightly

[smuudge]

Hi all, the problem is in the title. My Alpha CB24 leaks a very small amount of water out of the pressure release pipe when it is turned on, is there a quick fix for this? Many thanks.

yes a new pessure relif valve

yes a new pessure relif valve

or even a pressure relief valve

check the expansion vessel precharge as well

cold pressure should be 1/ 1.2 bar

Heating engineer surrounding the contents of a few cans of England's finest by any chance?

Cheers guys, i did get the gist of what was being said! Any idea on the part number /cost? Cheers!

whats the boiler pressure first cold and hot before you go throwing your hard earned at it

If the water doesnt pee out of the pressure release valve pipe then it holds good pressure, problem is i cant get it to stop letting water go.

The red pressure release dial is tight (although the actual release valve is loose but not leaking) so not sure if its a case of replacing or taking off and refitting tightly again. Either way it looks a pain in the arse to take off as it sits in the metal housing at the bottom of the boiler. Do you think the boiler may be shot then?

 

[kevplumb]

no but the expansion vessel might need a dose of looking at

You may find that clicking the head 4-5 times may stop it leaking but it may also nake it worse.

If only you would answer the question about boiler pressures we could give you further advice.

We dont ask you for fun!

Turn it off

its sitting at approx 1 bar cold then rising to 1.5 bar when its warm after 10 mins of running the heating..

 

[kevplumb]

right first change the prv

and while the boiler is empty check the expansion vessel precharge

 

[smuudge]

Ok will do. any ideas on how long the job should take and part cost? Looks tricky as the PRV sits in a metal plate thats connected to the bottom of the boiler...... cheers

r u sure its the pressure relief because these boilers r well known for leaking. but the prv valve takes about 20mins to drain swap then refill. as for price it depends who u get and ask when u call what amount of money the want for call out fault etc
