I am going to bury 1" in PEX in clay soil in North Carolina.
- Can I bury the PEX directly in the clay as long as the clay is firm and just put the clay soil back on top? Or do I need a bed of sand.
- I was thinking about wrapping the pipe in polyethylene foam tubing and snaking for expansion issues and some say that it will help stop or slow any absorption of chemicals that might be in soil (some say PEX can absorb chemicals) .
Also, I have the PEX temporally just laying the in trench and it supply water to the house. There is not any problem with that correct?
Checked with the city before I started on the need for a permit. They said if I am not changing sizing, not adding or deleting and it is under $15,000 I do not need one. But, I can get one if someone thinks it still a good idea.
I just want to make sure I do this right and to code.
