Hi Quick question. I'm having building work done and my quote details a Vaillant boiler and Megaflo system. I've been away while they do the plumbing and they have fitted a MAIN 24Kw boiler and a 210 MAIN unvented cylinder. I want a reliable HW/CH system and am not so hung up on the...

Pump now back on right way, air bled from it, all working and I've just been in the loft and there's no circulation of water through the F&E tank. Thank you everyone for your pointers. Richard.

Nige That's it :D . Thank you. I had to buy a new screwdriver with a large head but it must have taken about 20 seconds to fix it. A few splutters and then a steady stream. The boiler has now been on for 15 minutes, the right pipes are getting hot in the right order and the radiators...

The system was installed, and old, when I bought the house six years ago so I don't know its entire history. I've had numerous new parts (pump, bits on the boiler) but don't have its installation history. The non-return that you talk about. There is a junction on the outlet pipe between the...

Hi Apologies for starting a new thread about my CH/HW issue. I've done this because it's a different problem to the one resolved in the other thread. I've put a schematic of my system in my photo album taken from the boiler's manual. From what I can see, this lower schematic is how my...

Photos to accompany Potterton 2 system

I just fired it up again. The boiler comes on for about a minute during which time it sounds like a kettle heating up. It sounds like the water is getting to boiling point inside. It then turns off. The pipe running along the top of the boiler goes to the pump and on to the valve. It doesn't...

He didn't drain the system this time. He isolated the pump and put it back on the right way round pointing out of the boiler and into the valve. The problem of the boiler turning itself off now seems to be the original problem I had when I turned the CH back on last week before I had it power...

Hi It took a few days for him to come but he's just been this afternoon and swapped it round. I don't know what inhibitor he added but I know he put some in when he refilled it. I've previously used Wickes own brand. Anyway, it all came back on and off he went. Now, there's another problem...

Yes. Definitely he's put it on the wrong way round. Oh well, easily fixed. Interesting that the system still works fine (apart from the flow through the F&E tank). I've turned it off until he fixes it though. Thanks again. Richard.

Yup. He's coming round at 8am tomorrow to fix it back in its previous direction. Thanks for all the advice. Really great. Richard.

What a great forum. Thanks for the replies. I cannot see where the vent pipe is attached because all the pipes disappear behind the boiler and flue and it's completely inaccessible. However, what you say makes sense - if the first thing after the pump is now the vent pipe just before it's...

Hi I just discovered this forum. I hope somebody can help me out. I just had my CH & HW system power flushed and the guy told me the pump was on the wrong way so he replaced it the right way up. The Potterton Kingfisher 2 boiler, pump and motorised valve are all next to each other in a...
