I think we're all in agreement that I shouldn't be using the old copper pipe - whether it's chemically sterilised or not.
I was wondering now whether I could thread a new 15mm plastic pipe through the old copper - simply using it as a sheath, as no water will be passed through it? Hopefully it...
Thanks again for all your comments.
I'd happily rerun the pipes, only it would either require ripping up the bathroom floor, or going from the underside through the lounge ceiling. It's more balancing the destruction, but totally agree that if doing it, do it properly.
Is there any reason I...
As in the volume of water you'd need to run through the tap to clear the cold water is more with a 25mm than a 15mm, ,therefore you're waiting around for longer for the water to run hot. I didn't really think of that - just assumed bigger was better!
The longest run from the boiler would be...
Thank you for your comments.
Can I please check why you wouldn't trust him to do this - is it not good practice? The pipes are approx. 10 years old if that makes a difference.
Thanks

Hi all,
Just a quick question that I have so far received mixed views on.
I currently have a vented central heating system, which I plan to have replaced with a combi boiler in the garage. In order to link up with the existing network, one plumber suggested sending the cold water from the...
So I just fired up the HW. The hot return from boiler got piping hot instantly, right up to entering the cylinder. The bypass going back to the boiler got instantly hot, suggesting hot water was going back to the boiler and the pipe exiting the cylinder (going back to the boiler) got pretty hot...
So the 'hot return from the boiler' is red hot, so I'm happy the boiler is working. This pipe is hot right up to the point of entering the cylinder.
Is it possible that air in the coil will prevent hot water entering the cylinder (and therefore returning to the boiler), and the hot water is...
Just to add a little more to the puzzle...
When fired up together, we do get hot water, albeit heating up very slowly - would this mean that there is no blockage? The pipe leaving the boiler and entering the cylinder (mid level) goes through a gate valve and a 2 port valve (set to auto). These...
Hi all, just a quick update.
Replaced pump - the old one was full of sludge and red rusty water. Initially the boiler fired but then as before the pipe feeding the boiler got hot and the boiler shut down. I then fired up the central heating system and it gave out a massive gurgle followed by...
So I've tried firing up the boiler and turning it off manually after a few minutes, then repeating several times just to try and push some water through the system.
The boiler fires up ok, but still sounds like water is trickling in the pipes, which makes me still think air, but then a...
Morning - thank you all for your responses.
I reset the boiler last night and it fired up for about 5 minutes and automatically shut down. The hot water pipe exiting the boiler was red hot, but after a while the cold feed started to get hot - this hot water then started to back up into the...
So the bubbles wont stop when draining from the boiler - and when I then go in the loft the small tank is filling and feeding into the pipe that feeds the boiler and sucking a load of air in.
I think it may be time to call a plumber!
