Clean the pipe well before fitting. Yes, use a proper T - I replaced the cutter type with a T compression and the flow and range from the hose pipe increased dramatically. Rather than a washing machine valve I used a full-bore ball valve and also a check valve. The ball valve has a T-handle for ease of use. -- Peter. The gods will stay away whilst religions hold sway |

Yes, you fit an isolator without interrupting all water, so then you can fit a proper 3/4" compression tee W/M outlet, presumably the O/P has some reason for avoiding turning off the supply? |

'Emergency Plumber on Christmas Day Connectors'? That's what happened to a former colleague, the punched-out copper disc got jammed somewhere and they couldn't turn the water off.

Thanks for all the comments. Although it wasn't what I was originally asking for, I've subsequently found (the more expensive): https://www.screwfix.com/p/self-cutting-drain-cock-type-a-15mm/9543r Reviews a bit mixed, to say the least. However, that was after I'd bought and used the dishwasher tap to do a one-off emptying, and fitted a conventional drain cock. So I now have a spare dishwasher tap; maybe it'll come in handy if I feel the urge to fit more drain cocks in the future. -- Roland Perry |
