Water authority been into a company workshop urinal and requested they bring it up to spec with an air gap/ petcock etc.. I understand the principals behind the mechanics but never came across a job like this before.. I've done a bit of digging and as I under stand a petcock should be fitted in tandem with an auto siphon allowing the required air gap however I'd like a bit of guidance how I should best set this arrangement up to limit water usage when toilet not in use over night or weekends/holidays?
