I need to fit tees into hot and cold water pipes to make provision for the supply to our new kitchen.

At the moment, the pipework runs horizontally into the room I'm working in and then two elbows send the pipework up to the 1st floor.

Is it better to cut the pipework after the elbows and insert the tees or to desolder the elbows and put the tees in their place?

Cheers,

Dan

Personally I wouldn't get hung up about either method. Do whatever seems easiest but be sure there is enough movement/ length of pipe remaining to make the connection if you decide to cut them off.

I wouldn't recommend desoldering, you need to get the work spotlessly clean for the solder to take, and in my experience its not always very easy. Secondly, if there's any trace of water in the pipe, it will not solder, regardless of how much heat you put on it. I'd be looking to cut in the tees into a straight section of pipe, with a couple of compression fittings on standby in case soldering isn't viable.

Exactly what I done in the end.

All went fine until I undone the stopcock and seen a drip, even though water was still off at the meter.

Turns out I completely missed a joint whilst doing an elbow and tee at the same time. Hopefully the repair has taken, we'll find out in a minute.
