Hi ,
I have installed a 7500 liter rain water tank, which tahnks to the recent rains, has been filled in one day !!
Anyhow, I also installed a Hylow DHJ800 pressure activated pump. Basically, I have the rain tank outlet coupled to the pump inlet. The outlet of the pump goes to a T junction whereby it is split into 2 stream. Both ends of the T junction have PVC valves to close off supply if need be.
When the pump is on and the PVC valves are closed, should the pump not automatcailly switch off ? It doesnt appear to be doing that and I have one possible theory for this.
Assuming that the pump would switch off when pressure reaches a certain value, this would cause the pressure in the pipes to drop. The reason for this drop is due to the fact that the impeller inlet is open to the rain water tank. Does that sound correct ?
Any pump experts on this forum ?
