First time seeing this

[Robert Jones]

I am not real sure what to say about this configuration. The original home was built in 1924 with an addition added approx 10 years ago. There is a mix of plastic, copper and galvanized water branch lines. The end of this water branch line, which in actuality, is the main feed line to which other lines branch out, has a cap on one end. This same material is also used as a branch line to other items like an exterior hose bib. These pics are from the crawl space under the addition. Comments? Suggestions please.

Thanks,

Hi Robert,

the pipe looks like PE (poly- ethylene) water piping. It is not allowed for use inside living space (much like PVC). I do not know if that has always been the case, nor do I know what WA allowed when it was installed.

Nice hose clamps by the way.

I would probably say something about the fact that PE piping is not allowed in that application, and recommend a plumber correct it.

ABS is allowed to be use as a supply line, not as a branch distribution material. I never see it it used anywhere except on systems served by a well or spring.

FTR, I almost wrote 'except on well supplied systems'. Walter would have had a heyday.

I suspect that if Walter had any sort of special day reading that, it would be a "field day."

It's not ABS. It's high density polyethylene (HDPE) meeting the standards for potable water (NSF-pw) supply. As Brandon said, it's not for distribution. Like Chad, I only see it installed from the well to the pressure tank.

Thanks guys. This home was being serviced via city water and sewer.

Put a hyphen between "well" and "supplied" and I would've had a Happy-Go-Fun Day.

Of course it's HDPE. My bad.
