What is this thin pipe leaking water in the utility room?

FR_262

I'd like to suggest that it's nothing to do with the boiler. Perhaps it is the overflow pipe from a toilet cistern?

A COMBI boiler is just one that does Hot Water and Heating from the same source, NO Cylinder for Hot Water

A CONDENSING BOILER on the other hand, will have a condensate pipe, but this should not be metal, as the condense is acidic, and piped to a drain or soakaway, or as has been stated by SCRGI

ONLY a SYSTEM BOILER will have a PRV, be it a Combi, Conventionl, Condensing or NON condensing boiler, and the sparge/warning pipe should be piped to outside, as should ANY PRV for an Unvented Cylinder or Mains intake PRV as a warning pipe to indicate a problem with the valve or system over pressuring

If you are a Professional offering advise on here, GET THE FACTS RIGHT!!!!!!!!!!!!!!!

Sorry to hijack your post, Op.
But Mr Ted I am confused (ok I admit it does not take much) I have a Worcester Bosch condensing combi which of course I know does not have a cylinder, I thought a system boiler was a type that had a hot water cylinder, so therefore not a combi or condensing combi?

OP here install & servicing instructions, page 3 item D

I'll let Mr T answer the above question as it was directed at him

Mr_Ted

Google "system boiler" and you will get the definition from different manufacturers, they tend to give slightly differing explanations, but basically, from an engineering perspective its a sealed unvented pressurised Heating Circuit/boiler, be it a combi or conventional boiler, separate from the hot water system, no tank feed

Like wise you can get an unvented Hot Water system with water storage cylinder.
A combi gives instantaneous Hot Water direct from the mains, much as the old style multi point did.

Hell that must sounds complicated to a layman :rotfl:

So Basically "system boiler" came into being probably as a simplification of "Sealed Systems Boilers"

It is worth mentioning that Combi Boilers have also been around in different forms for decades in the domestic market place and the commercial, and also Sealed Systems have also be utilised widely in the Commercial Sector for years also

To stop any further confusion, that pipe is in fact the condensate pipe. On the Worcester Highflow it has a built in pump and this is the pipe that comes off it. It really should be into a drain, I would pop it back into the white pipe that the washing machine waste goes into. It will only discharge when the boiler is running. Once around 100ml of condensate is collected at the bottom of the boiler the pump will turn on for a few seconds and push the water out of this pipe.


ok didn't read all the replies and noticed it has been answered, but there are alot of conflicting answers that are totally wrong. I suggest if you really don't know, don't comment. Someone could take this wrong advice and end up doing something really silly.

Here's a guess. When the boiler was installed, the copper pipe was rested into the white pipe and the blue hose, with the rubber surround on the end, was pushed in to hold the blue hose and copper pipe in place together. Over time, vibration caused the blue hose to pop off and the copper pipe sprung out too. A better way needs to be found to secure the copper pipe in that white waste pipe.

except it's not copper it's plastic

Dangit. OK plastic then.:)

In the second picture, is that the same pipe looping over the black hose in an inverted U at the top of the waste pipe?

If so, that's an awful long way for it to have 'sprung out' from the waste, if indeed that's what's happened ....

More pics?

By 'the above', I meant PRV overflow pipe, not condensate pipe, as I think was obvious. I'm well aware of the difference between 'combi' and 'condensing'.
And where did I claim to be a professional? We're all just guessing on here from a single photo, and little else to go on.
The OP has already confirmed that it's a combi, so a poorly installed PRV overflow is as likely as anything else, in the absence of more detailed info, or better pics.
