Went to repair a main service where the pool guy used a shark bite tee and it failed. I saw the main and proceeded to cut out the sb with my tubing cutters. I cut and cut and cut. Thought my cutters were stripped. Then cut it with a sawzall. Turns out that main is pex. Anybody ever seen it discolor like that? It straight up looked and felt like copper.
Another discussion would be how to tell if it’s PEXa or PEXb without seeing the lettering. I couldn’t tell so I had to crimp it all back. I also don’t like to use the crimp brass fittings underground. They corrode badly as well.
On another note, the brass they use in the shark bites is straight trash. They rot out quicker than the underside of a New York State pickup truck when buried.

Inspector told me a few weeks ago that shark bites are approved for below grade installs as long as it is wrapped. Puzzled me but then realized the job security.

I’d have to see a better pic before I could comment. Maybe a pic of the piece you cut out up close.

Looks like a coating on the pex or chemical attack that’s discolored it.
If it’s pex.

I’d like to find a way to tell pex a from pex B without reading the letters.

If it’s 1” pipe, Boshart makes stainless crimp fittings that will work on either A or B.

I’m not sure how extensive Boshart fitting line is. I haven’t looked into all of it.

 

[jim285pro]

I looked them up. They make 1/2 and 3/4 also. Supplyhouse.com has them

It does look like copper.

A few years ago I did a service call out to an old gas station in a podunk town and they had pex that was discolored so bad I swore it was pb. Turns out it was clear pex that had accumulated a film of nastiness along the inside of the pipe that made it look dark grey

Yup, clear pex freaks people out.

Ive heard you can tell by taste.

Underground gets a stainless sleeve and brass Corp fitting. I hate call backs.

Are you referring to Polyethylene lines? We've been doing that more lately. Been using a thicker PE that is fusion weld compatible too. Blue with red stripe I believe. This is for insurance paid for residential service line replacements.

When we do residential lines on the customer's dime we still use K copper for 3/4" to 1-1/4".

Service lines where I live have to be K copper and nothing else.

It's called biofilm.

It's called biofilm.

Hopefully not. Usually it's just mineral buildup.

Ever change a slimy filter? 🤢🤮
