Hi all.
New to this forum and looking for a little advice please.
I’m changing the location of the sink in my kitchen and so need to move the stop cock, (which is under the sink), and all the other pipes too.
The mains pipe coming into the house is black 18mm OD going into the stop cock and a 15mm OD copper pipe coming out which feeds the house.
I believe the black PVC like pipe may be 18mm alkathene after searching the web?
I’m wondering if it would be OK to leave the old stop cock connected and leave it horizontal under floor and forget about it and put the out going copper pipe to the new stop cock about 1.5 metres away, OR, should I remove the stop cock and join new pipe to the old imperial black PVC one?
The pipe is almost certainaly 18mm and I would be happier cutting off a couple of inches and taking it to a plumbers merchant but this means using the isolation cock in the street and this would be problem because it also cuts of next doors too.
They wouldn’t mind too much for ½ an hour or a little more but if I can’t get what I want we’re are knackered.
I’m sure that there will be fittings and pipe inserts to connect the old pipe to the new pipe but it's finding them for certain.
I was just thinking that I could close the old stop cock until the new one is piped up and then just opening the old one and leaving it under floor. It would save me a lot of stress.
I was also thinking of using a full bore quarter turn ball valve instead of the old type.
Any valid opinions on that?
P.s. I’ve used a digital vernier gauge to measure the mains incoming pipe but it’s very hard to reach due to it’s present location. I’ve got 3 readings. 17.8mm – 18mm and 18.2mm so I’m certain it’s 18mm.
Appreciate any help.
