Irrigation pump blowing out connections on low-pressure side.

We have an irrigation pump that gets its water from a larger pump which supplies water to our entire community. Last night, one of the PVC pipe connections blew and flooded the entire yard. This morning I re-built the PVC connection from scratch and left it plenty of time to cure. Tonight, same thing. The supply-side line blew, this time at a threaded junction between the pump and the PVC supply tube. This happened when the pump turned on. It's clear that when the pump turned on, it created a great deal of pressure on the supply side. Could this be a problem with the pump itself, or perhaps a blocked line somewhere in the irrigation system? Shouldn't there be something in the pump system that keeps the pressure from backing up in this way?

Thanks

Since the main pump feeds the entire community are any others having similar problems or is it only happening to your irrigation pump?

Anti flow back & pressure relief valves ETC.

Do you have anti flow back valves with some form of adjustable or nonadjustable pressure regulators? What type of wattering system? A drip irigation or standard eg garden hose to soaker hoses sprinklers?

There are many ways to deliver water to your crops however all use or some type of anti flow back valves in order
to keep from contamaninating your main water source.

Please describe in as much detail how your water is delivered
to your pump & where it goes from the pump + all valves
pressure regulators or if drip type all emitiers + tube size etc. The more we know the better we can help you.

Thank you.
