Repair Pex tubing?


I've got a problem. I was digging a 12" trench in backyard today and just happened to put a small puncture in my well water line leading to the house. This trench quickly filled with water as I ran to cut the power to the well. This water line is made from black 3/4" Pex piping (Poly PE3408).

My question is, can I repair the small slice which is no more than a couple inches? If so, is this something I can get a Home Depot?

Also, is there something I need to do to the pressure tank that this pipe goes into?

Advice is greatly appreciated for I am without water now.

It's probably not Pex, more likely polyethylene or polybutyl? I yahood the code and one of the hits said to use insert fittings and stainless steel clamps. So cut it at the slice and rejoin with the insert fitting. They might have it at HD or a local farm store. Insert fittings come in brass or plastic. Not long after I moved into my place a plastic one let loose in my yard. The plumber replaced it with a brass fitting and said they hold better than the plastic ones.

BTW, be careful the power line to the well pump could be close to the water line. You don't want any more shocks today.

Jogr,

You were right in all apsects. I later discovered it was not Pex. The local Home Depot guy explained the same repair proccess too.

I also inspected that power line before I flipped the breaker for the well.

Thanks for your time, Jogr.

in a similar post about poly couplings, it was recommended to use brass couplings especially on a buried run on poly pipe. (I've had problems with brand new poly couplings leaking under pressure). Apparently the brass couplings will perform better (leak proof) and last longer - fwiw....
