This article series began with a look at the four basic types of pumps that are used, and also described the two major components of a water system pump, the impeller and the diffuser. Now we look more closely at these two components to see how they can be manipulated to affect a pump’s performance.
In this series of articles, we will be referring to systems that move ground water from a well to its intended point of use – the types of systems likely to be encountered by well drillers and other ground water professionals. We’ll start with a look at the heart of any pumped water system, the pump.
This month’s article focuses on the portion of a submersible water system between the wellhead and the house. To put things in perspective, let’s think about what needs to happen in this area to make the system work …
One of the most important aspects of installing a water well system is to provide a method of protecting the wellhead so that surface water, debris, insects and vermin do not enter the well. There are two primary methods used to provide wellhead protection …
Making a proper splice is crucial to a long-lasting, trouble-free installation. A good splice is watertight, has good electrical conductivity and is mechanically strong. There basically are two ways to make a splice - the tape method and the shrink-tube splice-kit method.
In response to a reader's letter, this month's column addresses the use of stainless steel or galvanized steel pipe couplings and check valves with galvanized steel drop pipe.
Submersible pump accessories are the plumbing and electrical components of a pumped water system that are particular to a submersible pump system vs. a jet pump system. We will cover the torque arrestors, cable guards and drop pipe this month.
The primary function of the pressure tank in a pumped water system is to protect the pump motor, which is accomplished by storing water under pressure so the pump does not have to come on every time there is a small, intermittent demand for water.
