Sure. Send them back and take a trip to Plumb Center.

Oh Jimmy, If your system has to be "powerflushed" every year then you have a serious pipework configuration problem that can't possibly be answered on a forum. A 10 year old system that was correctly installed and commissioned should never need to be "powerflushed". Ask your friends or...

The house was brand new 5 years ago and has run fine till a couple of weeks ago. Luckily I found a reconditioning place adilink from Wembley were I got the boiler spares from but this has me baffled and with me having two small children the cooler nights are sometimes too chilly for them...

Sounds like your header tank (the small plastic one) has run dry, probably due to the ball valve sticking in the closed position (horizontal). The header tank keeps your system topped up with water. As a central heating system doesn't actually consume water, any usage is mainly due to...

Yes.

You have a fully pumped Y-Plan system.

After all that....what an anti-climax. I found that problem on many occasions and always when the cold feed dipped before connecting into the flow. I always tee'd cold feed into the open-vent just before the connection to the flow and never experienced any blockage problems.

Ideal Concord. Replace the T/C lead and clean out the pilot injector, it will probably run for another 10 years. Cost of running? Ouch............

Guess you didn't give teach a shiny apple. Bet he stuffed his hamster down the cold feed.

Sounds fair to me, go for it. At those prices you are certainly not being ripped off. Good luck.

Ok, so all you have done is changed the pump. I presume that no drain down was necessary and the pump isolation valves worked correctly. From what you have described, there is no logical reason for the system to pump over. So, with serious straw clutching in mind, do you have a partial...

It sounds to me that the diverter valve might be faulty. Good luck.

Are the rads getting hot, or just slightly warm? If slightly warm then it could simply be the boilers pump over-run dumping hot water from the heat exchanger into the system when hot water demand ceases.

The make and model of the boiler would be helpful. It sounds like either the boiler stat or pump over-run stat may be faulty. A faulty boiler stat would cause hot water to be dumped into the expansion tank, this could also cause the open vent pipe to become detached from it's clips and drop...

Does the pumping over occur when Htg or HW is in demand, or both? Is the pumping over accompanied by any banging noise? Presumably the fault was noticed due to a running overflow. Was this the expansion tank or domestic water tank overflow? BTW, I disagree with your thoughts regarding a...
