I know what I'd rather do in this situation, but my buddy doesn't have a whole lot of money to repipe his trailer. He is doing remodel work and knicked a water line at a transition. His main water line is polyethylene 1/2. Seriously 1/2 off of the meter. Mind you no shut off valve anywhere. None under the house for the main or at the meter. Are sharkbites fine to go from polyethylene to polybutylene? I told him to rip all the poly b out and go in with pex. Again, can't afford it. Just curious. Only ran into poly b a few times and have ended up repiping everything that was poly b.

If the O.D of polyethylene is same as the polybutylene ( 5/8 ) then you can use shark bytes.
Make sure you use the inserts for inside the pipe.

We use John Guess fittings.

Trying to remember but I think polyethylene is still connected with just hose clamps, might be wrong here, I will definitely look up those John guess fittings lol

PB was connected with barbed fittings and crimp rings.
when we ran out of tubing to make repairs, we used copper or pex. O.D. are the same so sharkbyte or John Guest fittings will work. But make sure if you're repairing for a customer, that there are no guarantees.

Yeah poly b is no good. That's why I said I told him I'd rather rip it all out and start again. But it's for a friend of mine. He's doing all the work himself.

I have fixed a lot od those sort of leaks and the best way to fix Polybutylene is with sharkbite , just make sure the stiffner is in sharkbite
