been using these for a few years now and they'd work perfectly, then after about 2 months they'd just explode, so it was just a case of unscrewing old one and screw on new one, job done, carry on cleaning.
well now the manufacurer has changed the design and now after a couple of days they jam up, in fact today i put a brand new one on, did the front of a small house where i didnt have to move so didn't even let go of connector and when i released it to move it wouldn't seal, so after about 3 minutes work it needed changing.
has anyone else found this and if so have you changed to another type? if so what?
