|In response to Frost Free anti-siphon sill cock limiting flow|
I too have a similar problem that has been plaguing me for a while. I have a frost-free sill cock with an in-line anti-siphon device (the anti-siphon is mounted on the output of the sill cock which then connects to the 3/4" hose). I believe that it's the anti-siphon device that is limiting the water flow, not really the sill cock itself.
The anti-siphon device seems to be mounted to the sill cock with a special thread so that only an anti-siphon device can be attached (so you can't remove it -- I just wanted to test to see if it really was the thing limiting the flow). I was hoping to find a replacement anti-siphon device with a higher flow rate, but I can't seem to find them anywhere. It would seem that replacing the entire sill cock is my only option, huh?
I've seen other sill cocks which have the anti-siphon device mounted on top of the sill-cock (I assume that these are not in-line). Are these better for water flow?
