Here we turn our attention to pump and motor protection in a single-phase system, the potential problems and the available solutions.

During the next few months, we will focus on the electrical side of pumped water systems. We’ll start by looking at the components in two-wire and three-wire single-phase systems.

Splicing submersible pump cable is part and parcel of every submersible pump installation, because every submersible pump installation has at least one splice, between the motor leads and the pump cable.

This month’s article focuses on the portion of submersible water system between the wellhead and the house.

One of the most important factors when 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.

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. For simplicity’s sake, we will divide them into two categories – down-hole accessories, and aboveground accessories.

Check valves permit water flow in one direction only, and are required on all submersible pump installations.

The primary function of the pressure tank in a pumped water system is to protect the pump motor.

Controlling the amount of air in a conventional pressure tank is crucial in providing an efficient and reliable pumped water system.
