Hi
Thanks to all who replied, the answer is almost unanimous and is the one I argued for. Five of us said that a stopcock should be opened full then turned back half a turn, the other two said it should be opened half way.

Good to everyone agreeing on something which is rare on a forum.

ask the other two how they would know it was half way.

 

[macplumb]

Fully open 1/2 turn back

gonna be the same all day long, aint it.

Fully open back half a turn to stop it gettin seized. if you get problems with water blowing out of a tap too fast and spraying everywhere either fit a flow regulator or fit/throttle back a iso valve at point of use till desired flow is reached.

 

[Guest123]

ask the other two how they would know it was half way.

I assume half a dozen turns without getting too precise over what the halfway point is.

Wonder what the colleges teach the kids?

We're having a (friendly) argument over whether it's right to fully open the main stopcock in a house or crack it open a few turns.
Right now it's 5 for against 2 and I'm curious to see the result on here. I'm not telling which way the voting is going until the result on here is counted!

bored are we?

Fully open then back 1/2 a turn.

If you want to limit the flow use a PRV and flow limiter. Relying on the stopcock can cause the jumper to virbrate and the pipes to be noisy.

Open fully then turn back a turn

Spot on, that's what I was taught

some questions are timeless

Always open full then 180' turn close. Makes it easy for the next man to use. End of

 

[Furgazoid@hotma]

Open sd valve fully open and crack back. If valve is half closed, eventually the water can wear away part part of the seating and it wont shut off
