There aren't many household systems more confusing than plumbing, which is why I stopped trying to fix mine on my own. I realized that taking things apart was increasingly more difficult, so I stopped guessing and started looking for a trained expert who could come out and help. When I found the right professional, it was amazing to see how much easier things were. They went through, evaluated my plumbing system, and made changes that changed my home from the inside-out. Check out this blog to find out more about how to avoid plumbing problems and when to hire a professional of your own.
Although submersible pumps are common in many newer water wells, a practical pump choice for a relatively shallow well is an above-ground pump. The installation above ground usually makes pump repair more convenient, but there are added inspection steps to take to ensure that the remaining components within the well itself are working as designed.
Unlike a pump submerged deep within water, an above-ground pump is clearly audible when in operation. If no sound is produced when electricity is supplied to your pump, the pump may be faulty. If the pump is simply not providing an adequate supply of water, the problem might actually lie beneath the ground surface and not with the pump itself.
Pipe configuration clues
If you have an above-ground pump, you will notice that it is attached to either one or two pipes that travel down into the water well. The presence of one pipe indicates that the well is relatively shallow and that the pipe is likely less than 25 feet in length. The presence of two pipes indicates that the well is likely deeper than 25 feet. Since pump replacement requires the disconnection of attached pipes, you might as well also lift the pipes from the well for inspection.
All above-ground pumps work in conjunction with a check valve located at the bottom of any attached pipes. The purpose of the valve is to prevent water from falling back into the well each time the pump switches off. The check valve is also referred to as a foot valve. A single-pipe system has one check valve. A two-pipe system has only one check valve, but it also requires an additional component to connect the bottom of the two pipes.
In a two-pipe system, water is pumped down one pipe and back up the other. An injector nozzle connecting the bottom of both pipes draws in additional water from the well. Both the injector nozzle and the foot valve should ideally be inspected whenever the pipes are disconnected due to a suspected pump problem.
Over the course of several years, encrusted mineral deposits may lead to a partial blockage of the injector nozzle. The foot valve relies on a spring mechanism to open or close in response to the flow of water. Unless you are certain that your pump is faulty, the repair of a failing component at the bottom of the pipes could possibly restore the capacity of your pump to perform as originally designed.
If an above-ground pump is located in tight quarters, it can be somewhat difficult to access fully. Contact a plumber for further information about well pump services.Share
