Fitting an external tap at a commercial premise

[Malcolm Greenhouse]

I have been asked to fit an external tap at a mental health facility to enable the external paths to be hosed down. What form of back syphoning measure is sufficient for this installation?

I used to work with someone of the same name (used to be a postal worker, then health and safety officer), anyway I digress, if it’s just to be used like a garden tap, then I think (although don’t quote me) it can be a double check valve. If it’s to used near a bin store, I think the fluid risk category changes to a 5. Best bet would be United Utilities water regulations department, as they enforce the regulations for your area. Alternatively seek guidance from Wateregs uk, or look in the water regulations guide.

Let us know what UU says. I'd imagine that so long as it's intended for use with an above-ground hose (to be fitted with a spray terminal that shuts off when you release it as per Water Regs) and not connected to some kind of device for dispensing chemicals with the water, a DCV will be fine, but I'd like to hear it from them.

Will do but my in house maintenance manager suggests that the attached makes it Class 5 because we would be fitting a hose union tap, what do you think?

If you think about it though, and similar logic applies in the gas industry, it’s a commercial premise, but then installation is deemed as a domestic setup. However, as I said, this is why it’s best to seek guidance from united utilities - it’s their supply and they enforce the regulations.

Neil Foster and Ken Lacey (if they’re still there) are nice helpful gentlemen.
