Question:I am trying to pump a manhole that is about 30 feet deep and the truck is sitting up a hill about 10 more feet. What is the best way? It’s sucking but very slow and I don’t want to burn up the pump. Would a 2-inch hose work better than a 3-inch hose? Any suggestions?Answers: Maximum water lift at sea level is 33 feet. Changing hose won’t help. You’re near the limit of vacuum lift***Try using a length of 3-inch PVC hooked to your hose. Make a 1/2-inch hole in the PVC so it will draw a little air.***Can
