I was looking for 1" , rather than 28mm, which is a couple of mm too wide.......

Hi all, I'm looking for a way to connect a 1" copper pipe (on a solar collector), to a 22mm or other more normal size. I'd prefer compression fitting to solder. I've checked out a number of places but can't find anything with a 1" compression end - they're all threaded at the 1" end...

Hi, I have worked out that I can replace a saniflow in an extension, with proper drainage - there's enough fall to the existing manhole based on 1:25 fall - total length is about 17 metres. Previous owner obviously took the easy route. Thing is, I want to plumb two bathrooms to it. The...

Hi, I want to lay laminate, ideally straight over ceramic tiles in a through kitchen/dining room. The tiles are approx 30cm square, flat topped, but obviously have a slight bevel on the edges where they are grouted (dip probably 1.5-2 mm from high to low. They are laid over concrete...

It's venting from the HW cylinder into the large cold water tank, not the heating circuit venting into the heating header tank.

Sorry My original post was slightly inaccurate. javascript:emoticon(':oops:') It's not gravity fed, it's an open vented system with a circulating pump. The immersion isn't connected, but I'll check. The boiler thermostat is possible but in the past it's proved very oversensitive and has had...

Hi, I've got a gravity fed heating system, with a potterton boiler, cylinder in airing cupboard and tanks in the loft. For the first time in years there has been a discharge from the hot water cylinder vent pipe (which didn't quite vent into the cold water header tank, which is how I know...

Hi folks, I've discovered through a tortuous process of elimination, by turning stopcocks on and off and playing with taps, that I'm getting a back flow from the cold supply, via a Grohe thermostatic shower valve, into my unvented hot water cylinder, which eventually builds up enough...

Thanks for the advice!!javascript:emoticon(':D') Very Happy I pressured the system up to 2.5 Bar and could see it visibly dropping. I went round checking all the radiators. In the kitchen I heard a hissing from under a cupboard and discovered a radiator valve from where a radiator had been...

Thanks for your replies. I meant to say bleed radiators, not drain radiators. They fill up with air and as I fill I have to keep bleeding and the pressure drops again. The sealed system was put in about 5 years ago as a retrofit by the company that did my loft conversion - not sure if...

Hi folks, Basically my question is "Where is all the water going?". My heating has been getting noisy recently. It's a sealed system and every 6 months or so I have needed to repressurise it up to 1 bar through the filling loop and drain a couple of radiators. However, it got very noisy...

Hi folks, My unvented cylinder is now discharging almost continuously from the vent pipe. Varies between a fast drip and a low trickle and I'm now having to descale my car windscreen regularly. Expansion vessel was replaced about a year ago following earlier problems where the vessel lost...

Hi folks, A friend is being proposed a horizontal hot water cylinder as part of a loft conversion. I also have one of these and am not convinced it's as good as a vertical cylinder as it doesn't seem to warm up as quickly as our old cylinder (although this could just be different coils etcs)...

Hi folks, I've worked out that it would be relatively easy (well, that's what I think now) to raise my loft cold water tank by about 30cm. At the moment it's about 2ft above the shower head and about 5 feet above the bath taps. Would raising it by a foot have a significant effect on...

I'm looking for advice on how to stop a tap soaking all my guests. In our downstairs toilet, since the cold water was switched to mains pressure we now have a cold tap which can send water once around the very small basin and about 3 feet into the air. This is sufficient to soak a small...
