Well. I found this one:
I don't know about the website or seller.
Replacement Irritol 311A
But Rainbird makes a similar looking one. I don't know about the piping in between the flow in/out though.
Rain Bird 100-ASVF
See what the experts have to say first........
Many thanks for the link Seansy59..................Ray
Since the entire operating portion of a 311A can be unthreaded from the body, it can be replaced with another "converter" assembly. The easiest one to lay hands on can be the Lawn Genie L1010, which is really an industry-standard Richdel design.
The reason for this interchangeability, is that the 311A is a plastic copy of the old industry standard brass valve. Everybody made converters for them
Many thanks for this information, it should make my job of maintenance much easier!!.........Ray

===================================
Good morning wet_boots, I looked into the Lawn Genie L1010 valve adapter and it appears that it is for brass valves and the L2010 is for plastic valves. Is this correct?
Many thanks, Ray
Many parts of the country never saw that Hydro-Rain antisyphon valve, and wouldn't know from parts. I only saw a few of the Champion/Richdel combinations that Richdel sold, way back when. (I would appreciate posters that input their location, so that specific advice can be given)Just go to a sprinkler supply house such as Ewing or Hydroscape. That valve is still available. So are replacement parts.
