pipes
PIPES is the common name for piperazine-N,N′-bis(2-ethanesulfonic acid), and is a frequently used buffering agent in biochemistry. It is an ethanesulfonic acid buffer developed by Good et al. in the 1960s.
I'm retiling my bathroom, and so everything in this photo minus the copper pipes must be removed.
Anyone familiar with these screw fittings that go over the pipes? They have filed down areas to get an adjustable spanner in there to turn them, but when I grip the copper pipe and the screw...
Hello. I'm new to this forum and I'm hoping to be able to learn some things as well as contribute as best I can.
This might seem like an odd query, but I need to determine what kinds of plumbing pipes I have, and approximately what percentage of each type. I'd appreciate any help with this...
I'm currently refurbishing a room. Plumber has been in for first fix to lay new pipework for new radiators.
He's laid fresh copper pipe, however around the joints they are all green which I believe is flux residue he hasn't cleaned up after soldering.
Not the cleanest of jobs but I'm not too...
We have a bathroom where drainage runs across the house to soil stack.
After shower especially in night when there is high temperature difference between inside and out there is clicking noises that impacts our bedroom (1) and more annoyingly our 3rd olds room (2)!
I am wondering what could be...
Hi , need to cut flow and return pipes and hot and cold pipes from boiler to put back into wall vertically approx 3 inches , the pipes in question are 400mm below combi boiler but approx 4mts in distance horizontally , if I was to drain a radiator (I don’t have a drain valve ) would this remove...
I am looking to replace an oldish boiler and hot tank with a combi boiler. The house dates from around 1968 and quite possibly the (copper) piping could be that old. I had someone round to give a quote and they said they would not recommend a combi boiler because the piping downstairs was buried...
I'm currently refurbishing a room and in the process adding some internal wall insulation.
The wall has been stripped and my plumber is coming this week to install/reconfigure the pipework for new radiators.
The walls are solid brick and as I am installing insulated plasterboards, we agreed...
I can’t work out how to connect this pipe back to the pipe on the wall. Every time I try water leaks down the back wall. Help appreciated. Thanks (images below).

I am told I need to replace my boiler. I am considering a system boiler so I can lose the tank in the loft and feed it direct from the mains water. My rads are fed by 10mm plastic pipe. Is there much of a pressure increase with a system boiler and will the plastic pipe joints (e.g. John Guest...
This is regarding the hot water, but I didn't have a clue where else to post it.
We live in a 22 year old Barratt house, we have lived here since new.
The start of last year, we had to have our hot water cylinder replaced as it started leaking (closed system).
Because it was a different make...
Hi All,
I'm trying to work out why the 'rule of thumb' is ~3 radiators on a single 15mm run...
I've calculated the heat demand of my house at ~14kW:
3 bed 1930s solid wall, end terrace, no wall insulation
7 radiators
2 air change per hour for all rooms
21deg in all rooms
When I do the...
I'm a plumbing novice so first of all I apologise if I'm not explaining this situation correctly. I've recently renovated a house for my family to live in and we're having an issue with water not staying hot when the secondary return circuit is on. From a starting point of fully heated the...
Not on the hot but whenever a cold tap is ran in the bathrooms or toilet flushed the two cold water pipes reverberate round the house.
The cold mains and the balanced cold.
We changed the water inlet valve with PRV last week but the problem has come back quickly.
Is the street pressure too...

I havent ever really done any steel pipework hence my question to you . .

Hello, I hope someone can help me. I'm in England. I would like to know if it's okay to bury copper water pipes under a concrete floor. I've tried to look up the regs but's it's like double dutch to me. The pipes will be wrapped in hessian, overlaid with PIR insulation and then screed. I don't...
Hi : I’ve no idea about plumbing so please be patient. The plethora of pipes in my hot press, which one is the cold water feed to my central heating system? I have an oil boiler in the garage. Thanks.
We're having the loft converted at the front of our house, and the plumber has routed the new water and central heating pipes via the rafters in the back loft (which isn't being converted). He's wrapped some insulation (looks like TopSleeve) round them and assures me it'll be fine. I'm worried...
Hi all. Thames Water lead pipes - meter to stopcock liability? I have had contradicting info. from TW & employees regarding the TW /consumer onus to repair or replace and various dates relating to policy changes. I was denied a free change or repair 5+ years ago. Also been told that near future...
