Bib Tap

[besenzig]

Hi

Could someone please explain what a Bib tap is and if it has a check valve does that mean a separate double check valve is not needed.

Thanks

a bib tap is an outside tap, (if you know what that is ) having a check valve doent matter, as the water regs say an outside tap needs an internal double check valve

Thanks for that.

Just wondering whats the point of an outside tap with a check valve if you still need an internal double check valve.

Frost damage.

A Bib Tap, is one that fixes on the wall, usually with a backplate elbow, most common with Belfast sinks etc.

An Hose union Bib tap is most use as a garden tap with provisions for a hose pipe, they can be purchased with a double check or without.

The regs for same says, a stopcock and draincock, and double check valve is required, it can be in the tap (bad idea) or in doors in the warm where you can winterise it properly.

The pipe for the outside tap would run from a tee piece under the sink, then a stopcock followed by a double ckeck valve and then drops to the floor along the back of the units. It then rises and exists to the ouside wall to the tap.

My problem is the lowest point to fit a draincock is on the floor behind the units and this would be difficult to get at. Can you suggest an alternate arrangement or can I leave the draincock out?

Thanks

Yes an alternative is to drill a hole higher up so you can drain it out in the winter.

Another is to prevent it freezing with lagging and maybe a heat tape on the pipe.

Another is to replace the damaged pipe each year.

I think its unlikely to freeze up as its internal in a heated kitchen, surely there is minimal risk of freezing.....

Is the outside tap inside as well.

another alternative depending on access etc is to drill the hole in the wall slightly downwards to the outside, cut a tee in the inside and run pipe slightly down to outside, on the outside fit a bend facing down and 3-4" of pipe then the back plate, when required you turn off supply inside, open tap (which is lower than the bend and the water will drain out, leave the tap open then any water inside that freezes will expand along the pipe and not burst and will defrost again in the spring

LOL...what a comedian.

wrap a rag round it when it's cold and bother none.

What is funny is:-

Bloke going down the streeet sees his mate with 'one arm' and says 'Where you going John?', 'Going to change a lighty bulb' replies John.

'Won't that be awakward?' ask his mate. 'No says John, I've still got the receipt'.......

Forget the outside tap, you should be on the stage

Perhaps you should read your own posts first.

So is in inside or out, and do you think turning the water off will stop the pipe freezing unless you drain it.
