Used with an irrigation welll, water depth is about 12 feet deep and bottoms out about 16 feet. Do yourself a favor and get a good foot valve at the end of the suction hose and brass fittings at the inlet and outlet of the pump and use teflon tape on all connections. Fill the pump reservoir and primes quickly, steady output pressure through a 50’ 1/2” hose for the garden. I have a 4 way splitter on the output side, does not have enough power to run more than 2 at a time but not a problem for me. First pump quit priming after about 4 months, Vevor honored the warranty after minimal troubleshooting and haggling and sent a new replacement for free and it’s been fine. Im confident it’ll be fine to fire up again in the spring, Would buy again!
