not yet i've been told to to hire a smaller pump for a day or two to run a diagnostic test

to ascertain the flow and refill rates etc ...

pump 500–1500 litres
stop
measure recovery after 30 min / 1 hr / 2 hrs

That alone will tell us more than days of guessing.

What happens AFTER this test

Once you’ve done that, we can size your permanent system properly:

correct pump head (likely higher than this unit)
correct flow rate for 120m garden run
whether you need pressure vessel or not
whether pond + irrigation can run simultaneously
