We have a large underground rainwater tank that I use for watering the flowers.
I’ve got an electric water pump that just stands by the opening and I lower a large hose down into the tank.
In winter the pump goes into store and I’ve just taken it out and put the hose into the tank, primed the pump and turned it on.
So far I have used 3 full watering cans to prime the pump. The pump itself seems to be working fine, but I just cannot get any water drawn up from the tank through the pump.
It’s never been a problem before, even on first using after winter. Any suggestions please?
It looks something like this one …
