I have 4 hose bibs on my house. I think 2 of them are connected before my pressure regulator. The other two are after pressure regulator. There are no backflow prevention devices in my house. House was built in 1959 in California.
What is standard? Pre or post pressure regulator? Does it matter?
And do I need a backflow prevention device? If so do I want one/bib or one for my entire house?
Thank you
