I broke a braided hose broke on the hot connection to the kitchen tap over the weekend.
I've replaced the horrible screwdriver shutoff valve with a handled version and also used new copper pipes.
Problem is I get a leak in two places - one at the top connection of the shutoff valve (I used ptfe tape on the thread and screwed it really tight. And one where the copper pipe connects to a plastic elbow joint (rubber o-ring with a plastic collar and plastic screwtop).
Now the o-ring seal did work fine before I replaced the copper pipe, so that kind of points to me doing something wrong. (using a junior hacksaw not the best for cutting copper pipe but my cutter broke so i'll get a new one).
Any ideas on how to get a watertight seal?
