If this happens it is possible to re-prime the pump with water from another source. The pump motor will run but no water is delivered. Where a one line or two line jet pump is installed, you may have lost prime at the pump. No water pressure due to lost pump prime: IF you have no water pressure, absolutely no water in theīuilding water supply piping, and no water in the water pump itself, THEN we've lost prime and the one line or two line jet pump may be unable to bring water back from the But there can be other causes of loss of water supply that are not pump priming trouble but something else. If the diagnosis determines that you need to re-prime the water pump, the instructions are provided in this article. Recurrent Lost Prime in a Well Pump? - How to Fix Repeated Water Pressure Loss First Let's Correctly Identify The Type of Water Delivery Problem You've Gotīefore we get into details about how to prime the well pump, or diagnosing why the well pump keeps losing its prime, let's make sure we're tackling the correct problem. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article series describes how to prime a water pump to restore water pressure to a building. Replacing a foot valve in the well requires that the well be opened and the well piping be pulled out to permit removal of the old valve and installation of a new one. The sketch shows how a foot valve works and where it is installed. Page top sketch courtesy of Carson Dunlop Associates, a Toronto home inspection, education & report writing tool company. Here we describe the common causes of this water loss and thus the loss of well pump prime. The air-bound pump can no longer lift water out of the well. Loss of well prime means that the water inside an above-ground well pump has been lost along with water in the piping between the pump and the well The spinning impeller inside of a typical jet pump requires a water-filled cavity in order to develop enough lift power to bring water up from the well.
