Sorry for neglecting this post... Regarding my set-up.. I have a closed system with a boiler in the loft, next to the boiler is an expansion sphere (which I have now re-plumbed). There was a one way check valve between the sphere and the CH, so the sphere was not able to do its job ). I...

Just moved the non-return valve to mains side and used an isolating valve to bridge the connection between the flexihose from expansion tank and heating system. Thanks for the help. I appreciate the advice I have been given by you all... PS I know I shouldn't have anything between the...

I used to have ... I'm up and running again,'nice and warm' 8) I have not made any mistakes with the drawing... So I can assume from what is being said that I should remove the valve, (coloured blue) and install it on the mains side of the feeder. :oops:

This is my current arrangement. For clarity I've left out the pressure gauge which sits on top of the expansion tank... Am I right in thinking I should have a non return valve to the right of the mains feed. And I should remove any valves between the expansion tank and the system? TIA

My central heating system is a closed system with an expansion tank. There is a filler valve on the mains side of the expansion tank that allows me to top up/pressurise the system to the recommended 1 bar. The connection from the expansion tank to the is a braided pipe with a valve on it...

If you have a soldering iron and some solder. I suggest you re-solder the off-pcb connectors. They have a tendency to crack away from the sockets. This can be fixed by a new dollop of solder. My suprima 60 was doing the same until I re-soldered the off-pcb connection sockets. If you look...

My suprima 60 was doing something similar. I removed the PCB and re-soldered a number of dry joints which generally were the off-board connection sockets. That was about 2 months ago and it cured that problem.. Regards DM

The boiler is at the top of the system but it is fed by the pump on the floor below (in tank cupboard). Last year I had a problem with the pump leaking. I was constantly topping up until I replaced it so I suspect the inhibitor was 0% for a while...

Thanks for your interest guys... When I drained down the system the water was clean. I removed the heat exchanger expecting to find it full of crap and it was clean, no more that a couple of eggcups full of crap, is that to be expected? On the issue of a powerflush I think that is...

[Copied form other thread] The system was installed by a plumber on recommendation of a neighbour of mine who is and ex-plumber. He uses the same guy to do his work for him so I feel reasonably confident that he knows what he is doing. The boiler is sited in the loft and is fed from a...

I suspect that on Tuesday I may be buying a new boiler because the heat exchanger in my Potterton Suprima 60 has a crack in it. It picked a cracker of a time to go wrong ' New Years Eve' :( If replacing it I would like to get something that will slot in as a replacment without too much...

What is wrong with my CH system. In the past 2 months I have replaced 3 radiators that have perforated. After the first one went I made sure the system had inhibitor in it. When I drained down to deal with the other 2 rads (that leaked within 2 weeks of each other) the water was clean and...

How would I deal with using a leak sealer, would it not just travel all around the system and be seriously diluted where its needed. Is the heat exchanged too hostile an environment for this to work in :?: On the issue of it being a naff boiler. Yes it has given me lots of problems in the...

Is it possible/advisable to fix leaking heat exchanger by welding. I think I can see the crack at the back. Its about 2" long. The exchanger does not leak until the system is running, ie heat exchanger warm and under pressure. The boiler is a Potterton Suprima 60, closed system. Ta much...
