My sump pump discharge pipe was discharging water in to a bad area. During heavy rain (3 inches in 24 hours, let's just say), the area forms a puddle completely covering the discharge pipe. When this happens it dumps a lot of water where the discharge pipe meets the 90 degree PVC joint that takes the discharge line under ground. The discharge line has 10 feet of head, then 20 ft horizontal to the back of the house, then connects to a 90 degree PVC joint and goes under ground. Underground, it goes 20 feet then 90 degree turn and goes about another 40 feet. I extended the discharge pipe and additional 10 feet where the area is better drained. This puts total horizontal pipe length around 90 ft. Is this too long for a half horse power zoeller pump? Any insight will be greatly appreciated.
