I need to replace or refurbish my 30 year old Champion Sprinkler anti-siphon valves. They are leaking or streaming a lot of water out and need refurbished. How do they come apart? Can I take them out and down to a Champion Sprinkler dealer for replacement units? Who in the 87111 area handles these units?
