When you're facing the task of either replacing or installing a new well pump to service your home's water needs, finding the right one can make or break your investment. A well pump should not only deliver water efficiently for your household on demand, but it must work without the need for habitual maintenance or constant care. So before you replace your unit with one that's identical to the old one or buy a one-size-all model, there are a few things to know before you invest.
The Ground Work
You should understand the ground where your well is located and the depth of the drill before you install a new pump. Shallow wells are considered below 25 feet in depth, and though some can even be dug by hand for an ample water supply, many that are already drilled are subject to fluctuations in the water table. Deep wells generally run from beyond the 25-foot mark up to hundreds of feet, so finding a reliable pump that can create the needed pressure to move your water the distance is a large part of selecting a unit. If you have a fluctuating water source at either shallow or deep sources, you'll have to buy a convertible pump designed to meet large differences in table content.
Understanding your ground composition is important for selecting a well, as sand, silt, and any bacterial or algal growth can make an impact on the efficiency of the pump system you choose.
Turning on the Pressure
Well pumps come in many flavors to meet the needs of your ground and home's capacity needs. Though capacity is important, you should select a pump based first on depth, then narrow your selection further according to your ground type. There are two main types of pumps you can consider for your home:
- Jet: Jet pumps use the power of an impeller to drive water from your water source to the surface. Single jet pumps work best at shallow depths, because atmospheric pressure does most of the leg work for your unit. Double jet pumps allow you to tap the energy of impeller power at a deeper source, where the motor is housed at the surface and the impeller is located within the pipe. Convertible well pumps are a type of jet system that either use single jet or ejector components to retrieve water at fluctuating table depths.
- Submersible: Submersible pumps use a system that is submerged in the water source, with impellers stacked in the housing that drive water upward. Both deep and shallow wells can be serviced by a submersible system, but wells subject to silt, sand, or contaminant growth, may be better off with a jet system. Submersible systems tend to be more reliable, but must be installed and serviced by a professional like T. W. Stanley & Son Well Pump & Plumbing Repair, due to their remote housing.
