Having grown up with compression and solder fittings for copper pipe I guess I've missed the introduction of pushfits, but as I'm still young enough to learn new tricks......
I understand the basic principles of pushfit connections. But the thing that has put me off a bit has been that under pressure I felt they might give way. Obviously that's not the case otherwise other people wouldn't be using them.
So how do you release a pushfit joint after you've made it? If the thing has the ability to increase its grip when the pipe tries to come out (as it must do) then I'm curious as to how you "persuade" the joint that you want it to break.
And (assuming you can release it) can these joints be re-made afterwards, or do you replace the fitting?
Finally for the pushfit beginners course, are there different pushfits for copper and plastic pipes, or are the pushfits common?
Sorry if these are real dumb questions from plumbing 101, but like all these things you have to start somewhere and because I've always had a viable alternative I've been reticent to give pushfits a try.
