I suspect this is a rather simple question to some but here comes my newb question for the week [emoji2] . I'm in the process of redoing my setup including plumbing, this time I would like to use flex for portions, however I haven't worked with it before in this application. My question is this, for connecting up with rigid sections do you just simply solvent weld it into a slip fitting end just like a pipe? I've dry fitted a piece and the schedule 40 flex fits great however given the limited contact it has with the fitting walls unlike a straight pipe section due to its ridges it has me seconds guessing the connection.... So, what's common practice here?

It's the same as standard PVC, but you need to secure the fitting and let it dry before bending or you can weaken the bond and cause a leak.

Also if you want a super sharp or tight bend you can heat it easily with a Professional heat gun or propane torch applying slight pressure.. Once in the position you want hold it there until it cools. I use a adjustable bungie cord when heating to bend.. .

Once the solvent glue is applied, the flex PVC will push all the way into the fitting. Let it weld fir a few mins and you're good.

If you look hard you can find cement made specifically for the flex PVC. My local big box stores carry it but it's not as prominent as the normal all-purpose stuff. It doesn't seem to be a strict requirement based on the number of people who seem to not know it exists, but I try to use it when I'm gluing flex just in case.
