I'm considering PVC 40, PVC 80, HDPE and PEX-A for my 35' main water line from the meter to the house.
- Single story home with 53 PSI
- The pipe will be buried 18+ inches, with the frost line in my zone being ~4-6 inches and CA code requiring 18" deep buried.
- Ground is not rocky, no major roots.
- For cold water main line only. Will be using copper for exposed sections and PEX-a throughout the house
Considered PC 80 for added strength, but generally this is for industrial use and may be overkill.
PEX-A would be ideal since I'm running this throughout the house, but finding the right fittings is/has been a major headache.
Copper too expensive and not necessary given the alternatives.
City says they generally use HDPE, but I am having difficult finding fittings as well. City also says PVC is acceptable and schedule 40 is plenty strong for my house.
Hesitant about PVC because of the (potential? internet argues about this) leaching from solvents, though I'd only be looking at ~3 couplers and an elbow.
Local supply stores carry PVC 40 (450PSI) and PVC 80 with all fittings (don't know what PSI these are rated, if fittings even have ratings).
Any reason not to go with Schedule 40 PVC?
