I have a PVC underground water pipe which feeds a faucet in my backyard. I
use this faucet to connect garden hoses as needed.
This PVC pipe connects directly to the water meter and is always under
pressure. The faucet-riser just sticks out of the ground with 18" of
schedule 80 PVC pipe (threaded, thick-wall, charcoal PVC). I would like to
extend this PVC pipe by adding another 100 feet of pipe and a faucet in the
further reaches of my property.
If I want to adhere to Code, how far must the new faucet be above the ground
(soil)? Do I need a vacuum breaker at the new faucet? Is it actually OK to
use Schedule 80 PVC pipe as the riser for the faucet, or do I need to use a
copper pipe riser? What is the minimum burial depth of the PVC pipe?
Thank you for your help
