I have 12 Rads on my oil system.,,7 downstairs and 5 upstairs.
I have to bleed 1 radiator upstairs daily and another every few days , also 1 rad downstairs every few days, The rest are fine.
Have I a leak under the floor? Could it be something else?
Is there anything I can do without a "big dig"??
I'm fairly brand new at this game!!
Thanks

Certainly sounds like you've got a leak somewhere.


And before you ask.........

(despite spending 38 years in the Gas fitting and Heating/Plumbing trades)

.......I've never found an easy way to trace one. Sorry.

Hi,

I believe that radiator leak sealant may be worth a try.

Slightly drain a rad and add the sealant through the bleed hole.

I'm not sure that adding it to the header tank would get the required circulation as the tank is only there to top up any losses.

The other possibility is a badly designed system drawing air in or muck in the system (sludge in a system actually causes hydrogen production). If you've got an open-vented CH system, there'll be a little header tank (most likely in the loft) feeding the system. Isolate the water supply to this tank (by tying up the ballvalve) and mark the water level. Check it again a few days later. If it's dropped - hey presto, you've got a leak. If it hasn't, you've probably got muck problems.

Thanks to everyone for replyiny and suggesting remedies..
I'll try them and see. Any "dig" will be a last resort!
