New outdoor faucet question

[walter]

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

Some of those answers depend on where you live. Up here where it gets cold, it must be buried 48". Other places can go less. Some places forbid the use of PVC for any water use. Still others require a metal shield or at least a tracer wire along the plastic tube. It is certainly a poor choice for a riser out of the ground.

Since you want to adhere to code, find out what your local code is as it may differ from the rest of us here.

Just use a frost free yard hydrant.

Another factor is if you need to use it in the winter or not. If not, you can make provisions to blow out the line with an air compressor. In which case you don't need to freeze proof the whole thing.
