    Hi Guys.

    Firstly I am new to the forum. I am from Blackburn, England.

    I need your help please. I have a small leak from the a white plastic pipe which feeds from under my Vallient Combi Boiler and leads outside. The leak is from the u-bend. I have attached a picture to help.

    Please advise me on what the purpose of this pipe is and what would be the best way about going to repair it. I tried some tape but it leaked through. The leak is not major but still needs repairing.

    Many thanks

    This is a slightly more closer picture showing a more accurate location for where the leak is actually from. Many thanks folks

    It’s a condensate drain. Basically waste water vapour from the combustion process.

    Best repair is to replace the leaking parts. They are solvent weld.

    That pipe is the condensate pipe,if you can separate the pipes at the bend when boiler is off,you could dry them and use some joint sealant such as Rectorseal Tru Blu.
