Outside tap advice. (Yes really!)

[JCplumb]

Thanks for the replies chaps, I will leave it to the customer to decide, but I now have more ideas to throw at him, and more pricing options 🙂
TYVM.

fit a sure-stop to the bath panel and a doc under o/tap!!!

 

[johnnyplumb]

If you fit a sure stop valve under bath you could possibly fit the switch In a adjacent cupboard

great idea,
but would the customer pay the extra £40 or so for it ?
i doubt it, especially if he's a landlord.

You can buy a tap with a screw out drain in the base, I would either offer that with a disclaimer about draining down, or a surestop switch with a drain in the pipework, I agree with coring the hole through and sleeving it.

That's a tap with check valve

And not compliant with the water regs. DC valve needs to be within the building envelope.

I gave the customer all the options today and he settled on a bit of pipework coming out through the bath panel with an ISO then the pipework goes back in under the bath and goes outside.
Not what I would have chosen, but the customer is king and all that.
Thanks oodles for your advice chaps 😉

I might add that he was asking me to just do the tap from under the bath without an internal isolation point until I mentioned that I would have to include a disclaimer on the invoice if he chose that option.
Don't you just love landlords?

Out of interest Mike, what happens if your replacing an existing outside tap with check valve, is it within regs to replace like for like when no check valve has been plumbed internally?

"Double check valves have been shown to be susceptible to frost damage and should therefore be protected against freezing by being installed inside a building, or by other means."

WRAS Recommendation R15.20

As long as you protect it from freezing by another means then you should be okay but I personally wouldn't put my trust in one of those tap covers.

I should not steal Mikes thunder but to answer your question Bob, they can be installed as a replacement only, like for like or if the original tap had no protection & it is not practical to install a D/C on the inside (fitted kitchen units etc).
That is the only reason why they are still on sale.

Just to add, you can now buy a 6 metre length of tubing so you could put the switch pretty much anywhere.
