When fitting isolation valves to hot & cold taps under the sink can somebody tell me how much pipe to cut off is it around an inch and also is it ok to use Ptfe tape as I don't have any jointing compound

Ptfe on olives! NoooooooooDepends on which type of isolating valve you use. If it is the ordinary cheap & nasty Ballofix type valves, then it is about 1/2" to remove. Surely it is just a matter of you measuring how far a pipe goes into each side to find the centre cut off length?
Compress the olives & slacken back & put a couple turns ptfe over the olives to help seal them well. Paste is better.
Many thanks. Can you please tell me where I can purchase them from and what names to look out forIgnore the YouTube "plumber".
If you cut an inch off the pipe, the pipes would be slightly too short if there is no movement in them.
It is up to you what valves you use, but if you want or need better quality valves that will probably turn off properly & without leaks, even years in the future, then you can get full flow valves which also have better internal seals for another couple quid. Cheap ones will do fine though.

that's just for decorators who haven't got a clue.
I asked about the Ptfe instead of jointing compound because a plumber on Youtube was using it and I wanted some expert adviceWell he did ask could he use ptfe as a sealant because he'd no paste! He is a diyer. :smile:

Many thanks you seem a real gent who is genuineDepends where you are I guess. Plumb Centre or most other plumbing merchants will do both the cheap type & better types. Screwfix will probably do them. I will take a look & try to send you a link.

No slight on any previous posts but no ptfe tape doesn't belong on olives, best advise or not..
This is the full flow version. If it has the better internal seals, then it won't leak later & it helps with flow if you have gravity fed water.
