Huh? Are you some elitist valve snob? Rain Bird ASVF valves are the sturdiest most long lived valve of that kind I've run across to date. No solenoid cases splitting, never a failed solenoid in fact in the many years I've used them. Never a leak. Better than Irritrol or Hunter. The guts are the same as a DVF. These valves were in fine shape except for the glued threads. I salvaged the bonnets, guts, A/S caps and solenoids, though I'll probably never need them. Inline valves are not required by code or by climate where I live. Anti-siphon valves are easy to get to and work on, and they can be hidden well on most residential jobs. BTW, you use a Toro logo as your avatar, and dare talk about anything else as "trash"?
