PEX Is A Sturdy Pipe: Repairing Using Sharkbite Fittings

Share Article

Mr. Rooter's Tip Of The Day: Repair if you get a kink or the pipe is pierced.

Replace if the pipe gets a dent or becomes pierced!

If the damage lies in a straight run, simply cut it out and install a new piece with two crimped or push-on couplings.

Mr Rooter Plumbing specializes in the free second opinion, Mr Rooter’s Daily Tips and being the most referred plumber in the Northeast Ohio and Southwest Pennsylvania regions. According to Bob Beall, president, “PEX pipe, although versatile and flexible when making a mild turn, won’t take a tight turn without kinking.” If it becomes necessary to begin forcing the pipe, it is too tight.

“Once kinked,” says Mr Rooter, “commonly when it goes through a stud or around an object, it will need to be repaired.” It is also recommended to repair any PEX pipe that’s been dented or pierced.

It is possible to to use crimped PEX fittings or push-on fittings. “Using crimped fittings is not all that hard,” according to Beall, “but it’s easy to make a poor crimp, especially in a cramped position, and it requires and expensive crimper (over $100).” Push-on fittings simplify the tough plumbing job!

And tackling tough plumbing jobs is Mr Rooter’s specialty, according to Brett Keisel, who knows a thing or two about tackling! Beall says, “If the damage lies in a straight run, simply cut it out and install a new piece with two crimped or push-on couplings.”

BONUS TIP: Use the same techniques you would use for copper pipe.

Mr Rooter’s Tip Of The Day

Tip #1 Repairing a kink at a corner or turn will be a little more complicated because you have to crimp on two couplings or add two push-on fittings in addition to the elbow. No matter what fittings you use, first, mark a line on both sides of the damage. Make sure you go beyond the damaged area by several inches so you’re working with undamaged and fully round pipe.

Tip #2 Cut PEX pipe with any sharp knife–even a pocketknife. However, the easiest way is with PEX cutting scissors.

Tip #3 Crimp a PEX coupling of the pipe diameter into one of the main pipes. If you can’t get the fitting on, the pipe is probably out of need to cut two pieces of pipe to replace the damaged section.

Tip #4 It will be necessary to cut two pieces of pipe to replace the damaged section.

Tip #5 Crimp a PEX elbow into one of the replacement sections.

Tip #6 Then insert the open end of this section into the coupling in the main line, and crimp both the elbow and the coupling.

Tip #7 Repeat the process for the replacement section at the other end of the elbow.

VERY IMPORTANT PEX ELBOW OPTIONS: When installing an elbow in PEX pipe, you have two options–using a combination of crimp-on and Sharkbite-type push-on fittings or doing the whole job with push-on fittings.
