What could cause this pierced pipe?

[Outpost]

First time poster... See the attached picture for a pretty impressive puncture in a pipe.

Installed 1 year ago during a full Reno, I went to turn on water to my hose bib this morning and didn't notice the hole until I turned it on! I was quick to turn it off and wipe down the walls, so no damage!

But what could cause this? Is it pipe failure or for sure someone poking it somehow?

I'm just a homeowner, so have no experience at all!

Thanks all!

Thank you... First timer... Each forum has it's own quirks to get used too!

Looks like it must of had water left in the pipe when the temperatures dropped below freezing. Is that exposed to freezing temps?

I don't know how that would happen looks almost like a slice but that's just a guess

Yeah, should have noted, this is inside. No exposure to cold.

Looks like it was defective to me and just blew out.

That's my real worry... This is the only pipe in the entire house I can see! What is behind the walls?!?

How much pressure are you running? I'd be checking that first.

looks like grey poly pipe, that was involved in a nasty law suit about pipe failure

https://www.handymanhowto.com/leaking-polybutylene-pipe-replacement/

chlorine in municipal water systems attacks polybutylene pipe which causes it to become brittle and crack lengthwise, resulting in massive leaks. The homeowner believes the polybutylene pipe becomes so brittle that any movement or bending during a splice repair causes a new leak a short distance away.


look on the pipe for these numbers, if it is poly pipe, repipe your house,,or it is going to flood

That’s superpex

Has all the tell tale signs of freeze damage. PEX is freeze burst resistant but that short piece is too short to allow much expansion without bursting. Is the pipe near an outside wall?

well ****.....

It’s definitely not a freeze. Copper freezes looks similar but with this stuff, the rings and fittings would have gone first. Defective pipe would be my guess. Send the pics to the manufacturer and cross your fingers. Wirsbo had some problems 10-15 years ago. Still dealing with that pipe.

A few pieces of additional information, but first, thanks for all the responses! All are much appreciated, though obviously there is nothing conclusive at this point.

Pressure: there is no pressure on that section until I turned the valve leading to the hose bib. Note... the pressure at that point of the piping is direct city pressure... (gauge and reducing valve are not engaged at that part of the line. On another point, pressure to the house is at 50 which seems low to me, but whatever.

Temperature: This is interior, though on an outside wall, but it is insulated and we don't get terribly cold here in Vancouver.

More pictures.

1. I don't know how to read pex, so there's a picture of the pex for you to check out the coding.
2. Set up. The main line comes from the city at the bottom. Hose bib line junctions off to the right and through the wall (the puncture is on the bit that has a release into the house for whatever reason).

Thanks again all!
