Hi,
I have a frost-proof yard hydrant near my well. I'm assuming it's teed off the line to the house, as I've seen no evidence of any pipe going from the house out to the yard.
Recently, the county tested the water and it was quite high for coliform, so the system needs disinfected.
The water guy at the county said that one way the well can get contaminated is from the frost-proof hydrant. He said new installations are required to have a backflow preventer between the hydrant and its tee to the main line into the house.
Question:
A web search shows many different kinds of backflow preventers. Could someone please provide a link to an example of the kind I need?
Thank you!
Backflow preventer for yard hydrant?
