Has anyone used breaker valves on pumplines using only primary treated wastewater?

Breaker Valves are common on pressurised irrigation systems to let air into the pipes when there is a pressure reduction to reduce the risk of soil being drawn back into the pipes.

Even distribution of primary treated wastewater into trenches is best practice and a means of reducing the clogging effects at the start of trenches and getting better dillution of fresh toxic wastewater along the whole trench.

If a pump is being used then how do we prevent siphoning of wastewater back out of higher trenches into lower trenches or back down into the pumpwell if the non-return valve leaks due to hair etc?

A breaker valve up hill and only just before where the pumpline branches out to each trench should help prevent siphoning once the pump stops.

Has anyone tried this or had a problem with it ? Do breaker valves gum up?

I wouldn't think so. The mechanism is outside the liquid flow.

- I suspect you are right the more people I talk to !

Sometimes you just have to try it! If it doesn't work, you're out a few bucks.
