Have a customer with Wanner pumps going to an Omni arch. The pumps are fed by tanks mounted above them, about 6 feet above the floor. What's happening is when it shuts off, water siphons out of the nozzles. It's not been a big deal because it's reclaim water and it keeps it from smelling. But we want it to stop. Is there a simple vacuum breaker that can be put inline to stop it? The only ones I find are not rated for this pressure. Any suggestions?
