Awesome man, thanks. So I'm thinking of getting a 58 gpm pump. As far as I've understood, this baby would have a head of 28,5 feet, ≈ 14,25 PSI. How come smaller pumps that do like 26 gpm can produce 135 feet of head ≈ 67 PSI? Because the tubes have a smaller diameter?
Which should I go by to estimate the power, i.e. the length and solidity of the water beam, the gpm or the PSI?
