Side Entry Ball Valves (2 of 2)

water board regs and wras regs people plz need to be 1000000000000000% right which way i go

Note This Is A Commercial Setting Eg Schools Etc Where High Traffic Is Normal

during the schools shut down (aka school hols) 3 (me, building inspector and water-board) of us went round inspecting the water and heating systems in schools, we do this every 3 years to look for problems and check water meters etc,

went to a well brand new school (2 years old approx) everything ok heating and meter wise etc, the last thing we have to check is toilets, undo the the concealed panels takes the lid off the cistern, water board guy takes a look for wasting water etc (jobs-worth ) and see a brass ball valve (part 1) extended arm (which i love brass ball valves because theres less wear and easy to change parts but thats going off point ) and hes says thats illegal so i take a look and theres a dcv on the incoming main just after the iso and hes still said its illegal as water can still back flow.

now before i challenge him i want to make sure im right and dont want to charge the local a shed load to change every valve in the school if i am

summary can you use a part 1 with a dcv and be water regs ok etc

if no what ball valve can i fit needs to have an extended arm (float arm) and would like it brass if pos, because he also said you cant use one of these with the plastic silence tube on as that one can back flow (part 3)

i think i have made it as clear as i pos can
any q please ask

As far I was aware, part 1 valves are not wras approved no matter if there's a dcv or not. An argument could be if the dcv failed, it could back flow. So will have to be either a part 2 or a fluidmaster type ballvalve..

already looked the one i have says part 1 with dcv is ok now hes telling me no have they been updated ??????????

So what your saying is that you can no longer use a part 1 and dcv on a cold water supply connected directly to the mains
