Hello to all what is the best way to revise for the water regs exam I know its open book muiltable choice but have any of you guys know the best way to revise for it thanks
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
so what is??DCV isn't sufficient for cat. 5.
Double checks only good up to cat 3 (single up to 2) even something called an RPZ valve (mechanical back flow protection device) is only good up to 4.I was going to say cat 5 and would you use double check valves
Mike, I would be very interested in any details you may have on the above, especially the combination of DC & trigger, is this still OK if hose can be left in the sink?To be fully compliant you need to plumb via a break tank for both hot and cold but on a domestic kitchen sink you can now fit one using DC valves as long as the pull out spray is equipped with a trigger mechanism that shuts off when releases.
A few manufactures are now also supplying kitchen sink mixers with a fixed length flexi hose that clips in to a curved section. I've fitted a couple and they are nice.
