is the f/e tank full if so the cold feed to system is blocked.

your cold feed will be blocked just where it tees into the CH circuit

blocked the cold feed either sludged or airlocked , try blowing down it.

sounds as if u have a blocked cold feed from header tank

sounds more like a blocked cold feed to me mate sorry

Magnet will be sticking to the iron oxide blocking the pipe. Blocked cold feed for sure. Nice simple fix shouldn't be to expensive.

Sounds like your cold feed is blocked or partially blocked. Its usually ay the point where it tee's into the system.

Thanks Mick. I'd switched off the the system and made sure it's not timed to come on again until problem fixed. Good to hear it isn't likely to be the boiler. Sorry to ask a daft question but I take it that in order to check that the cold feed is blocked or not, I'd need to disconnect the cold...

Why was the 'cold gravity feed blocked off' in the loft when it should be going to the cold side of your bath mixer?

without going into detail your system is under positive pressure the vent/cold feed are neutral and negative pressure to the pump. so a blocked cold feed will result in the water going up the vent.

I've had to unblock a 28mm blocked cold feed. So they all can block.

Blocked cold feed pipe or an airlock, have you got water in your feed and expansion tank? (the little tank in the loft)

tony if the cold feed was blocked the system wouldnt fill i think the poster means the feed to the downstairs but is dosent add up :? :? :?

Firstly, when i find the problem, i'll let you know. In answer to your question, the water isn't rising through the vent, its coming up through the cold feed. But this is my point, is the vent blocked meaning that the cold feed has to act as a combined cold feed and vent.

you could have a blocked feed from f/e tank.They normally get blocked at the tee where cold feed meets heating pipe.Only way to get over this is cut blocked tee out and fit new one pete

I would suggest that the cold feed is blocked where it connects into the system pipework. Trace the 15mm (usually) feed pipe from the small tank to where it joins the system and it may well be blocked in that area.

Cheers guys, you were right - the cold feed was blocked where it joint onto the main circuit (the T-Junction??). All sorted now - runs freely through the system.
