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.I have been asked to fit an external tap at a mental health facility to enable the external paths to be hosed down.

Made an appointment for UU on Monday and yes it is the same person, who are you?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.

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?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.
Inclined to agree with your supervisor, with some reservation. Do bear in mind that the document you show is industry guidance (i.e. the water undertakers) which can be over-ridden if the industry (in this case UU) decides. In practice, my experience with water regulation enforcement officers is they tend to be practical people with a common sense approach.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?
My vote is for cat 5 because, for example, someone might decide to stick the hose up a blocked drain in an attempt to clean it. A lower category might be possible but would require a proper risk assessment to justify it.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?
A homeowner might do the same though, and they’re still cat 3.My vote is for cat 5 because, for example, someone might decide to stick the hose up a blocked drain in an attempt to clean it. A lower category might be possible but would require a proper risk assessment to justify it.
AAIU these are industrial premises not domestic. Not the same risk profile.A homeowner might do the same though, and they’re still cat 3.
