 HDPE tubing oddball size
Author: Stutsman (CA)

My house was built in 1971/2 in Los Angeles County. The water main is (I am pretty sure)HDPE, black in color. The dimensions are 1.375” ID (1 3/8) and 1.900” OD (same as 1 1/2” pipe). I need to install a new 1 1/2” backflow preventer to it. I have looked at Ford Meter Box fittings but it means mismatched parts to make them work. Anyone heard of or seen this type of pipe/ tubing and know what fittings are/were used on it? To replace it means digging up 500 feet of asphalt. Any and all ideas are welcome.

How does that pipe transition to the house piping/meter (what kind of fitting)?
