Had a irrigaiton meter put in at the house,, 3/4" line, brought it in to property, elevated to 2' and left it with a cut off valve, I was going to install a drip irrigation to the raised planter boxes, (vegetables),citrus trees, and then a stand of containers along with a protected area for tomatoes and whatever,,, the problem I have is I have to put a anti-siphon valve first off the main line, no problem I'll do it, but from there I planned on breaking the header off into 4 different runs and installing a block valve out at the end of the one run towards the end of the property for future "hose dragging",,, all my research says there is "no" anti-siphon valve recommended with a block valve downstream.

I was hoping somebody could recommend a anti-siphon that would work with a downstream valve that I could get by the city codes. City is no help, they're clueless, just has to pass inspection,,,, duh!

thanks for reading such a long winded post,
