Ok mate, I appreciate that. I'll give it a try and report back. Thanks.

Ok mate, that's disappointing but I appreciate your advice, thanks.

While putting a tee piece into the DHW pipe just near the boiler, I've obviously disturbed one of the soldered joints in the DHW pipe just as it exits the boiler and there is a very small leak. I've never done any solder work and anyway I wouldn't attempt it because the pipe is hard up against...

Cheers mate.

Just wanted to check. Is it ok to tee off from the DHW between 2 to 3 feet from the combi boiler?

Ah, ok, thanks for that mate.

Thanks Jack, I can go ahead now without worrying about that.

After some work on my combi CH system I've just refilled it and put inhibitor in. I've just discovered that I've got a dead leg on my DHW system which I'd like to take out. Is it ok to switch off the boiler, shut the main stopcock into the house, open all the taps in the house to drain the...

Having just put a new radiator in my bathroom I found that one of the joints was weeping slightly so I drained the system, added PTFE to the joint and refilled and repressurized the system. Shortly after switching on the CH the boiler started making a funny noise for about a minute and during...

Hi kb and thanks for getting back to me, your answer's very helpful. The return on the rad goes to the main 22mm return on the system via the same arrangement of reducer and reducing tee as on the flow. When I repressurized the combi boiler I bled all the rads then repressurized again and...

I've just put a new rad in my bathroom and I've got a couple of problems. Number 1. I teed off the 22mm flow at a point about 6 inches before the manifold for all the other rads, but for some reason the new rad is slower to heat up and even after an hour the top corner of the rad, above the...

Number 1. I teed off the 22mm flow at a point about 6 inches before the manifold for all the other rads, but for some reason the new rad is slower to heat up and even after an hour the top corner of the rad, above the exit valve, is still not fully hot whereas all the other rads are red hot...

Yeah, good advice I think. Anyway, that's what I've done and without kinking it this time! Thanks for your input.

Yeah, bit of a daft question I suppose. Anyway, I've replaced it with another bit of pipe and managed to do it without kinking it. :lol:

Trying to feed 8mm pipe through a hole I'd drilled in the floorboard I managed to get a slight kink in the pipe in spite of using a 8mm bender spring - although the pipe isn't fully kinked. It was already linked to the new radiator. Do I need to take it off the radiator and try again with a new...

Thanks for that.

Just read them now. Got a bit lost with the stuff about putting earth wires across JGS couplings - are they needed across JGS fittings in CH flow & returns?

I'm doing some work on my CH system (which runs off a Duo-tec Combi HE A Range 28 model) and I'm intending to use some JG Speedfit plastic fittings (tees and elbows). The Screwfix catalogue says that these are suitable for pressurized and combi systems but I'd be interested to know if the lads...

Thanks mfarrow. I've also seen 2-port ones, which is what I would need. The problem is that they need soldering in, I think, and I've never done any soldering.

Thanks Jack. I take your point about not having 2 rads both feeding through one 8mm pipe.
