Title: Need Advice on Lake Water System
Post by: bill447 on July 28, 2020, 08:26:18 AM
I have a PK1A tank kit being fed by a Goulds IrriGator on a dock on a lake.  The system works fine for normal irrigation usage.  However, the pump cycles rapidly when the hose is turned on just slightly or a small drain applied (like the drip line to the pool slide or a mister). Is the solution to replace the 4.4 gallon tank with a larger one?

It sounds like the adjustment bolt on the CSV is tightened too much.  As long as you are using more than 1 GPM the pump should not cycle at all.  If using less than 1 GPM it should cycle slowly, not fast, like on for 2 minutes and off for 2 minutes, even with the 4.5 gallon tank.

Those Gator pumps don't usually build enough pressure to work with even a 30/50 pressure switch.  With the switch at 20/40 the CSV should hold 30 PSI while using as little as 2 GPM.
