Thank you for this forum!
I am having a battle with a Goulds pump which is now going into 3 weeks. I’ll try to explain the situation as best possible. This is on a small Caribbean island with not many resources for parts, pipes etc.
This pump supplies an entire household with water and is the ONLY supply of water for the house. It comes from a cistern. The system as described below has worked for over 25 years with pumps being replaced over the years. Always had been jet pumps.
The draw up pipe is 15 feet and then crosses over the cistern wall for two feet, then drops 9 feet to the pump. There is a valve at the top for priming. There is also a foot valve in the cistern. There is a check valve (one way flow valve) just before the inlet of the pump (I question if this is necessary). All piping to the pump is 1 ½ inch and the pump is 1.5 HP. It is an Irrigator but Goulds said this should work. Goulds said a jet pump is better but one was not available here.
The pump is new and was taken apart to make sure the impeller etc was not faulty.
The first problem is the pressure will not go above 38 psi. Second problem is the pressure cutoff switch will not shut off no matter how we adjust it. We have tried 4 switches and all the same problem. We have checked for air in the feed pipe and that seems not to be the case.
There is also a bladder tank set at about 18 psi. We have tried various settings on this also.
Any help would be greatly appreciated. Thanks Kitty
