Yeah I've been eyeing them up. Thing is they all come with a tiny hose and I want to attach it to a c.20m garden hose. Trying to work out if I can find one the same bore.
@JurekB surely the vacuum is just to get the system started? once that's remove it has no influence on flow rate .
Correct. Either you or a more efficient apparatus sucking only needs to get the 'water' below the base of the upper tank, preferably filling the entire hose, gravity will do the rest.
