Subject: What's this leaky thing in my boiler...? - thing.jpg (0/1)


This thing in my ferroli boiler (see attatched pic) has started leaking
from the valve thing at the
top.

What is it ? It's only attatched to the water circuit, so I assume it's
either a temp or pressure
relief valve.

The valve had a plastic cap (like a car tyre cap), and two O rings at the
bottom which have gone
hard and cracked.
The plastic cap doesn't look like it's meant to take any pressure, so I
suspect that whatever's
inside is leaking and the cap had been holding it until the O rings
cracked.

Unfortunately it's buried behind pipes so I've not been able to unscrew
the top bit (which I assume
does unscrew).

Should I investigate further - if something inside has broken/worn will I
be able to get a
replacement, or shall I just bodge up a proper cap to seal up the top
valve....?


Looks like pressure release valve from top of water pump, try draining some
of the water out of your radiator system.
