Excellent condition and fast schipping
KEVIN -- columbia, PA   6/5/2012
Best priced 24v valve. Has female 3/4 NPT threads so need adapters for hose connections.
TIMOTHY -- ft. worth, TX   6/26/2011
I was disappointed that the one in the picture was not what I received. The picture has a switch that turns off & on and the one I received had a valve that turns off & on.
