Hello,
I have a 22 gpm Grundfos SQE with a CU 301 controller. The manual says that it should be paired with a 2 gallon tank, however we have a 22 gallon tank. We had our original well replaced last year because we needed to put an irrigation system in our new construction home and the well the builder put in was not powerful enough.
Is it possible that the person who installed this newer pump gave us a bigger tank because it helps with the water hammering when the irrigation system turns on outside? It is just bothersome because when we are running a faucet or shower, it doesn't use enough water to keep the pump on constantly since the tank is so oversized, so it short cycles by turning on for 20 seconds to bring the pressure back up and turning off for a minute or so.
