Glow worm boiler

[Mcroxx]

I have a 2 year old glow worm boiler which was installed in new build home. At the side of my house there is a plastic vent from the boiler and then further along the wall say 2 metres there is a copper pipe. A few months ago I noticed the pipe had a steady drip and the ground underneath was wet. The drip seems to have got quicker in the last week or so. I have looked online and people say there should be a plastic condenser pipe which can drop - I can't see a plastic pipe only the vent. They also say it could be pressure relief pipe. I have checked the boiler pressure and that reads between one and two bar. I don't really want to get an engineer out if this is something that should happen or it's something I can fix easily. Any help appreciated

can you take a pic of the under side of the boiler (at the pipes) and the pipe outside please

Hi thanks got coming back so quickly.
Pictures as requested.

Img 23 and 24 are underneath boiler. 25 is the whole system. 26 is the dripping pipe which is to right of back door. 27 is another copper pipe i spotted which appears to be directly under 28 which is the boiler vent. I now wondered if the dripping pipe is the toilet overflow as bathroom is directly above. Not sure how to tell though and didn't think that pipe would be copper. However the toilet sometimes does not stop its self refilling after a flush and you have to refresh to stop the water flowing into bowl.

What size is the copper pipe? Is it the discharge from an unvented cylinder?

is it dripping out of the flue? this can sometimes happen with condensers

 

[Mcroxx]

no just out of the pipe

That pipe looks like the safety relief from the heating!? Which would lead to a drop in pressure... Although the black handle looks like its been left in the open position so maybe it's creeping past & topping pressure up :/

 

[Mcroxx]

Could well be overflow from unvented cyclinder which is in airing cupboard and would be directly above where the pipe is

Has to be 15mm, look at the mortar joint.

1. Unvented cylinders don't have an overflow.
2. Look at the mortar joint, an unvented discharge will be 22mm at minimum, that looks to be 15mm so it has to be the heating safety discharge.

 

[Mcroxx]

Measured pipe and its 200mm. Dripping cold water

 

[Dotty]

200mm? The one in photo 6?

 

[Mcroxx]

yep. the one with the green watering can spout in it

 

[Dotty]

Measure it again. The diameter. Not the length. That's photo 4 you're talking about.

Is the end of the watering can spout also 200mm?

I'd also be concerned about a push fit fitting being used on the condense!

yea well the soldering says it all 😀

 

[Mcroxx]

Sorry my typo. It is the diameter but 20mm

filling loop is open

thats the plastic the copper pipe (brown)

Should be a minimum of 22 but wouldnt be the first time i had seen one in 15 🙂

The copper pipe with the dodgy soldering is 20mm diameter. That's the one that's dripping

this one?



dont think that one would be dripping other than the cond leaking (white 20mm) pipe

 

[Mcroxx]

I will call someone out. probably easier

 

[heliotrope]

That would would be the best thing to do.

The pipe with the dodgy soldering is the gas pipe.

 

[Mcroxx]

Ha. Sorry i got confused. I was talking about the one outside. Sorry - new to all this.

 

[dancinplumba]

filling loop is open

look at the filling loop, it is on !!!!!!!

 

[Mcroxx]

Ive turned it off. Its still dripping for now. Ill check in a bit

 

[dancinplumba]

that pipe out side comes from the filling loop/ expansion vessel, prv, connection point

 

[REDSAW]

its had a exp valve done, i would be inspecting if that works ok too!

comisserations on the installed boiler though.

disconnect it. what is pressure showing on gauge ?
