Does anyone else double plug the wall and use 3.5 inch screws to fix to heavy things to this kind of wall.

Thanks but your ok using different makes together? The solder will take up any slackness?

have you noticed they feel abit slack in end feed fittings of a different make?

I brought some end feed copper elbows from screwfix flomasta I think the make is they seem really slack in the 15mm elbows I get from the plumbers merchants anyone else noticed this? They should still seal ok?

Thanks there just enough room at the top to have a service valve accessible. That's if I screw the female end of the flexi on to it. What are peoples thoughts on doing this? I no some prefer a 1/2 male to 15mm compression.

It has a 2 inch void at the back

Do most people tend to run the hot and cold feeds to a vanity basin behind the blanking piece of wood at the back. Or in front of it in the unit?

As the title. Or will the solder not run right as the olive that has been cut off will leave an indention in the pipe.

Thanks yes and there should be a check valve to stop expansion back down the cold mains. The valve was just dripping slightly. It could need an expansion vessel fitting then?

Thanks I'll check was a pressure reducing valve at about 3 bar but don't recall seeing an expansion vessel. Is it unlikely to it just start leaking cause the washer has gone in it?

Thank you, not sure it had one but I'll check. This could of lost its charge and not taking up the expansion causing the pressure relief to run abit?

needing to swap a 6 bar pressure relief as the one that in in is leaking slightly be it won't reseat with operating it for abit. Probably a stupid question but can I just swap for a 6bar pressure relief from the merchants? There not specific to the under sink heater? I have done all my exams...

The section to be tested was just a 500mm length of 22mm with an elbow either end and a 150mm section in the elbows. So not a large section at all. The rest of the pipe run is getting run after the plasters been in.

Thanks how long do you tend to keep it at 1/2bar for?

Did think about using one of the dry test pressure kit but the gauge isnt as accurate as a manometer

Thanks so do you not hook it up to a manometer then?

My gas safe plumber I work for, doesn't test his pipework before he applies corrosion protection as he say he trusts his soldered joints. However I'd like to be sure.

Can anyone confirm how to use this I hooked it up to my manometer and the pressure keep dropping. Thought there was no leak was just a full length of pipe with a cap on, was just testing the kit. This stopped when I put a spare piece of manometer hose from the open ended nipple on the...

I am looking at getting a new manometer. I was looking and there's one is about £50 that has glass tubes instead of plastic. Many advantages of this?
