Installing outside tap - Help!

[yerino]

What would you use then?

Remembering you will have to isolate the mains cold and drain the exsisting water out of the pipe so it don't freeze?

How do you drain the water out of the DCV if the drain-off is after?

Er, why would you want to BB? We're only talking about a cupful between stop cock and DCV. Aren't we?

Drain-off is to drain the water from everything after the stoptap.

In which case a DOC before the DCV wouldn't achieve that, because of the DCV.

and how often will those great big things fit under a little sink space? Mini Valves are fine!

Never failed yet yerino.

Apart from the handle, the Arrow valve is the same size as the thing you rather weirdly refer to as a "mini valve".

In any case, I wasn't advocating the use of this one under a sink - it was merely an illustration of the things that get the sap rising in some of us.

Don't know Arrow particularly. Most are OK on cold water, but some leak on hot. The better ones have a compressible gland seal. Peglers and PC's own brand are OK.


Only planet-polluting lower life forms would fit one of these

on an outside tap. Even the WRAS approved ones (most aren't) are not suitable.

They are not the same size As I have both infront of me and there is quite a difference

I use the big bore quarter turn valves for instances like hot water to a bath...

With mains the pressure is so great you can use a "mini-valve" as I call it or a ball operated valve as you call it!

Mains header tank in the attic... Cold mains coming in THROUGH a mini-valve!

Got me there, moment of stupidity

ball operated valve as you call it!

Wrong yet again. Nobody's calling it that.
The point is it must be full flow, or near to it, and not leak. Yours fails on the first count, and the second as well if it's a cheap one.
Cowboys and amateurs think they "get away" with fitting all sorts of junk.
