Deep-Well Pumps: How Deep Is Too Deep, and How Do You Get the Pump to Stay Put?

Posted on: 7 July 2016

Many wells are not nearly as deep as you might think. The minimum drilling distance is usually about twenty feet down, but it could be more depending on the underground terrain and the quality of water in the area. Really deep wells can occur as the result of not reaching the bedrock where your contractor would expect it to be. Since it is important to reach bedrock, the contractor may have had to drill until he or she hit it. In that case, you might end up with a well that is sixty to one hundred feet deep, but rarely does a contractor dig deeper. Then there is the issue of the well pump. Do you know how deep to put the pump? How deep is too deep? How will your contractor get the pump to stay put? The following information should answer these questions.

How Deep Is Too Deep for the Deep-Well Pump?

The greater the depth, the greater the pressure acquired under water and the greater the pressure needed to pump water out. However, your pump should not be adhered to the very bottom of the well, especially since everything underground can shift and come loose anyway. Your contractor will already know that a pump that can be used for wells that are sixty to one hundred feet below the surface of the ground should still only be placed on a spot some yards above the bottom of the well. He or she will also know whether or not the pump will have any difficulty getting the water into the plumbing lines from this position and will tell you what to watch for. Still, the only time you have to worry about your well pump going too deep is if your well is already unusually deep (i.e., greater than one hundred feet).

How Your Contractor Will Get the Pump to Stay Put

Typically, after the walls of the well have been covered in cement, rungs are placed into the wall to help the contractor climb into the well and help wate- quality specialists gather testing samples without having to jump several feet or yards into the well. Next, the contractor will install a bracket on the surface of the wall below the water line. This holds onto the pump tightly while it pumps water out of the well. Any time you suspect that the pump needs repairs, the pump will have to be removed from this bracket, hauled out into daylight, and examined to determine what needs fixing.

Got Hail Damager? What You Need to Know About Repairs

We had a major hail storm in our area. I could see the dents and dings on the side of our home, but I had no idea how to go about getting it repaired or what to expect from the process. Luckily, we had a great insurance agent who helped guide us through the process and put us in touch with great contractors. But, I know not everyone is as lucky as we are. As such, I started this website to help people like you who may have hail damage. I hope you will learn what hail damage looks like, what happens if it isn't repaired, who to contact and what to expect during the process of repairing the damage. I am sorry about the damage to your home, but I hope my website gives you information that helps you during this time.
