Hi all.
I'm afraid I don't know the correct term for this part and I'm struggling to find a manual/parts diagram to correctly identify it.
The boiler (Worcester Bosch 28i - not junior range) is approx 12 years old.
We moved into this property just before xmas, and lo and behold the first thing to fail was the boiler. It seemed to struggle if the hot water was running, the heating was on and another tap was running. Loud cranking noise and the 'kettling' sound was heard. I couldn't find the reset button at the time (turning off via mains and temp down to lowest didn't work). The reset button on the top looked more akin to a screw - later found out this would work by pressing it down.
Anyhow (attempting to cut a long story short)...a plumber we knew, thankfully, popped round just before new year and helped take a look at it. Turns out the pressure was 'wizzing' out of the relief pipe to the outside (initially dripping) which was then identified as a problem with the pressure relief valve (pressure gauge was dropping to near zero over time). New one purchased, replaced and all was well...
...until the last two weeks. Seem to have that cranking sound back before the boiler turns off. Simple reset and it seems stable for the next three or so days before the cranking/turning off routine.
Today - arrived home and boiler was off (and it's blinking cold today) - quick check of pressure gauge - down to zero...must be a leak? However before going on a leak hunt it was very clear the leak was coming from the bottom of the boiler. Opened the front up and identified the leak coming from the part circled in the picture below. This is the black plastic part which connects the pressure relief valve to a copper pipe (again, not sure what this is - cold water inlet?!).
Fairly certain it is from a pinhole/split (just by the way it's spurting out) rather than a leak from the connection to the copper pipe.
Mopped up underneath and stuck a bowl there and rushed off (in desperation) to try and pick up some jointing compound which 'might' work on plastic (don't really want to worry our plumber on a sunday evening) but everywhere was shut.
Tis cold...we have three children...and I'm not confident of tackling this one. Think I might stick the heating on later, run a bowl of hot water for the washing up and keep watching a bowl underneath fill till at least we have warmed up a bit. I don't suppose a few wraps of PTE tape and anything else over the leak would help slow the flow for a short while?
I need to know a: if there is a quick fix (joint compound) I can do tomorrow b: if this part needs replacing (most likely) c: if anything else is causing the 'cranking' which precedes the boiler turning off (unless this part has slowly deteriorated until it has split?
Apologies this is a bit long winded...the typing is warming me up somewhat!
Many thanks.
