Hi Guys,

I've had a leaking boiler for a while, but could never see anything damp on the boiler itself, just a puddle on the kitchen worktop after the boiler hadn't been in use for a while.

I think it must be getting worse now, as there is a small, continuous leak quite regular now. I presume it must be an O-Ring which has failed, but what's the best way to identify it before I strip it down? As I need to guarantee to fix it, as I have a small baby who needs to keep warm.

The leak is on what looks like a quick release type fitting directly after the Flow Outlet




So really my main questions and concern is:

- Best way to identify the O-Ring before removal
- Best way to drain down the system - the boiler heat hot water in an unvented tank, and also does the central heating, so this flow pipe is used for both tasks. Is there somewhere 'special' I need to drain things down completely? I presume refilling would just be at the normal filling loop in the airing cupboard (where the unvented tank is situated too).





Thanks a lot
Ryan

Thanks for the replies guys, I will take your advice.

My wife reminded me (luckily) that we do have boiler cover. I found the paper work, and it is from D&G, but it was via Potterton/Baxi. Do they repair that side of the boiler - as that is more plumbing isn't it?
