Keep your pump as close to the water source as possible.
Depending on what you have for static head, you may have to put in a relay pump to maintain the GPM. of your primary pump.
32.2 ft above water is max for suction (anything above is impossible because of gravity)... mgh little physics 101 haha
This is true, we would test our pumpers, to see that they would draw water @ 28'. The higher you draw, the less GPM you get at the nozzle even less when you figure in friction loss of your supply line. I have forgotten a lot since I took hydraulics & rural water supply courses 30-40 yrs. ago in fire school, it has been 15 or so yrs. since I have used it, but, if I need to dig through the archives, I can make it work, in a hands on situation.
And yes, gravity is NOT always your friend, on VERY rare occasions, it can be your enemy!
