Leak somewhere in the system...

Postby Flood » Wed Apr 21, 2010 12:04 pm

So after moving to a condensing combi, I have a leak somewhere in the system and it's losing around 1/2 bar every 24 hours.

Do you guys have any bright ideas that I could try before ripping up the floor? I've checked all rads, visible pipework and the boiler.

Maybe it's worth sitting by the boiler pipes for an entire day watching for a big stream of water??

I haven't tried leak sealant or putting aftershave in the system yet... But I really do need to do something soon....

Any help will be much appreciated...this constant leak is slowly killing my soul

It's a valliant ecoTEC plus 831 boiler

Simply Build It

Thats the risk of changing to a pressurised boiler/system and not upgrading pipework and radiators/valves at least.

Basically - nothing visible, start lifting floors.

You should start ripping the floor, although it will cost you but i guess that's the best option to do to avoid more damage.

is water escaping from the pressure relief valve? it may be that the expansion vessel has lost it's air charge
