Plastic 3/4” service entrance on a brass adapter
this one weirded me out-
DPW killed the line at the curb. I didn’t want to touch this plastic to brass adapter. I’ve never seen this- they normally have a small “pinch screw” and a compression style fitting
so I cut the copper and spun the old valve off. But it was tight! Putting muscle and leverage on it meant a slight twisting affect on the plastic. It wasn’t stable
I Spun the new valve on and the assembly didn’t pop off, hopefully it stays. Filling a basement with water seems like a bad day
This was a small adder job, we installed a new heat pump system.
anyone seen this style of fitting?

so I’m not nuts? That’s a little sketchy? 😀

See them all over the place in Boston area. Not on plastic but on copper only. Why is that service in plastic?

It sure looks like a flare fitting.
You can flare some PE tube. Often that service water piping is the thicker wall 160 psi version in a CTS (copper tube size) OD.
The yellow PE gas piping takes a flare fitting also.

Plastic is semi common, but the connection is odd. The guy that originally installed this "may" know something I don't

@hot_rod That makes me feel less queasy.

Hard to tell from the pic, it could be the Ford Grip Joint fitting. The nut looks similar to a flare nut. It has a bronze gripper ring inside. That would be more common than a plastic flare, which requires the flare tool shown above.,
For plastic I prefer the fitting with the extra "gripper" collar on the outside, bottom of the pages.
My home has a black PE plastic water line with a regular copper crimp ring!

Looks like the bigger issue is someone sliding something across the floor and not paying attention shearing the pe right off flush with the floor. You could shear copper off too but it would be a lot more difficult.

yes, the 'shear' would be a little easier to get out of jail it seems. The 'pop' is what rattles me.

a fusion welded socket fitting is probably the only thing that would be as strong as the pipe. a long brass barb fitting that has to be installed with heat is unlikely to fail catastrophically but may seep.

I've seen the water company here use poly with a flare joint that was made for copper. The guy used a torch and a normal hammer flare tool and slowly flared the plastic.
I couldn't believe it but he did it and it worked.
I took it as another one of those "you're not supposed to but it works". You could tell it wasn't his first time doing it either, looked like he's done it hundreds or thousands of times.

you have to heat pe to use barb fittings, not sure that flaring it that way would be much different other than overtightening could shear the flare off.

if it wasn’t for this nice HP job, I would not have touched the valve. I told the guy a 100 bucks, maybe that’s why I got the sweet heat pump job- no one else wanted to touch it.

Nice Job! Is Bosch on R-454B or R-32?

You must get a lot of snow.

It also helps keep it out of the weeds, grass blowing and dogs peeing.

yes it’s tall, I think it’s 15.75”
MassSave has some rules on height- yet their rules have changed twice in the last several years
this was custom made- we have about 30 of these stands out therethe Next batch will be a few inches shorter

This has me curious. Is it now blocked (DIRECTLY BELOW) ? Obsolete, or actually not directly below ? Is putting placards like this on residential dwellings common in some areas ?

MA requires a sign over the vent pipe. A Child was killed on Cape Cod some years ago when the vent pipe was blocked by snow….this is the result.
We (in MA) are also required to put labels on the air intake and flue outlet on condensing furnaces and boilers, The pipe has to me marked with labels along its entire length.
Apparently some HO or Plumber cut into a flue or intake and thought it was a sewer drain or vent.
MA is way over regulated, no common sense

yes we yanked the gas furnace but not the sign. There is a gas power vent wh still there though

We call them Ranger fittings the connect plastic to another type of pipe
