Replacement outside Tap

Question

Hi, I have recently had a repair done on my stop tap. The plumber removed the outside tap as a quick repair. He came back the next day to do the repair. After he finished the job i asked him about the outside tap. He said sorry i forgot to connect it. So off her went and reconnected the outside tap. My question is he's not fitted a DCV or a way for me to isolate the water during winter.  There wasn't a DCV installed before but does he not need to install one now? Thanks

A double check valve should be fitted to an outside tap, as there wasn’t one on it previously it would be chargeable.

It’s a basic requirement to install an outside tap with an ‘icv’ (isolation control valve) due to temperatures in Scotland it is better to shut off the connection to your outside tap to prevent it from freezing during the winter

You are correct an isolation valve is best used to save birst internal pipes in the winter, but this is an easy fix
Kind regards

Personally I would fit one, incase of frozen pipes in the winter, I would have thought it would be part of the WRAS regulations, but I would need to look this up.

Sam · Answer

You don,t need a DCV fitted but you should have an isolation valve fitted.

It's not a legal requirement however I would always fit an isolation valve as they are very cheap and makes it easier in future if there was ever a problem to just turn that off rather than the water to the house

Craig · Answer

No the plumber doesn't need to install a DCV he will only install one on customers request but he could install a the bib tap with a check valve built in.

Steven · Answer

Yes a tap must have both a double check valve and a separate isolating valve Plus a drain off point to comply with the water bylaws

Richard · Answer

There should be a check valve and an isolation valve. The check valve could be in the tap body and the isolation valve should be near the supply. The initial installation should have included these and as peace of mind one should have been fitted before reconnecting but not mandatory as it was a previous installation

William · Answer

It is good practice to fit and isolation vale to any appliance/outside tap. In the winter you will not be able to drain the outside tap and it may freeze and burst.
