We have a bid from a plumbing company to replace our water service from meter to house. The bid is to use polyethylene tubing rated at 160 PSI. The diameter wasn't specified. Not knowing anything about this, I checked alt.home.repair and other places and read that cross-linked polyethylene, or PEX, is great stuff. I don't think the product being proposed is PEX; it's from Wesflex and the literature the plumber left me doesn't mention "cross-linked." Is PEX better for the main service, or is regular polyethylene good enough?
Also, the proposal is to not trench but use a device that burrows underground, requiring just a few holes to be dug. Our run is over 150' and goes under brick sidewalk, flower bed, driveway, and shallow-rooted mature camellias, so not trenching sounds great. However, I never heard of this technology. Does it work, or will they just wind up trenching anyway?
The bid is around $5000. Does this sound like the right price?
Finally, I had always thought copper was the way to go. Is this incompatible with the burrowing technique because copper isn't flexible enough to feed through? If I don't want plastic of any kind because of health concerns, am I stuck with trenching?
Thanks for any thoughts or suggestions.
