always seem to have some sort of leak , I just sort one and get another , back of van is always wet I use hozelock fittings I put in hot water before fitting I have tried brass but always some sort of leak im not to worried cos I get my work done but is it just my van that's always wet or is this just part n parcel of being a cool windy
Pure H2o; I've been using those couplings for a while too after recommendations on here and they are very good.Had one fall apart on me in about 18 months use, so not bad going.Also using the rectus 26 style fittings for my taps and they are brilliant too. No more we let from the 19or21
