I need to replace my water line. It's about a 230' run. I currently have 3/4" ID poly, which is failing at the seam. I've repaired it myself about 5 times in the last 3 years.
Due to proximity to the gas line and my neighbors line, the first 150' needs to be hand dug. Alternatively, I can go with a directional bore under my driveway. I've received conflicting info from my bids. Once company said that they can't do directional boring because the 'vibrations on the road will cause the line to fail'. Another company said no problem, and gave me a quote. The last company also recommended trenching. His concerns are the rocky glacial soil. The soil is littered with rocks between the size of a golf ball to a cantaloupe. He states that with a bore, the line is smaller than the hole. The earth will collapse around the line and can cause stress on the pex line. This makes sense to me, but I'm wonder how concerned I should be. I want this to last for at least 15 years, preferably 50 years like the original poly line. The plumber recommended sleeving the line, but warned that it would be expensive. I'm waiting on the bid.
Any thoughts on the subject?
