I've got 2000 liters of stored water off caught off the roof of my shed (2 x IBC containers). These containers are situated about 0.5 meters off the ground but unfortunately the ground slopes upwards.
I intend to put in a small (350 watt / 0.5hp pump) with included adjustable water pressure regulator/dry run protection. (Link to pump I am considering) below the tanks.
Initially I intend to connect this to a hosepipe with the intention of putting in a simple irrigation system (which will probably have flow control valves for each feeder). I expect this system to water 2-4 times per day for a fixed amount of time.
I am somewhat price conscious as I'm doing this on a budget.
Do I need a pressure tank in this setup? (and also, do you see any problems with what I'm proposing to do)?
