Well Casing Extensions in CT

Well Casing Extension Service in CT

Well Casing Extensions are a natural “next step” to take when performing a jet pump conversion or replacing a submersible well pump in a buried water well. Buried water wells were the standard offering of well system installers until the advent of the pitless adapters in the early 60’s. All new wells must extend above grade a minimum of 6 inches. Existing buried wells are “grandfathered in”.

Homes with jet pumps (pumps that are typically located in the basement next to the well tank) can benefit from a conversion to a submersible pump. Submersible well pumps will generate better pressure and flow. Since they’re located down the well, there’s no operational noise associated with them.

What is a well cap & what does it do?

The well cap is the cover on top of the well casing that sticks out of the ground. It serves many purposes. Most caps, which are usually aluminum or a thermoplastic, include a vented screen so that the pressure difference between the inside and outside of the well casing may be equalized when water is pumped from the well. However, the cap’s main function is to keep contaminants out of the water supply.

What type of contaminants does the well cap keep out of the well?

A properly sealed well cap protects against all types of contamination. It is the first line of protection against nonpoint source pollution, which constitutes the majority of ground water contamination. Nonpoint source pollution includes runoff of pesticides and herbicides, soil erosion, and elements from the street.

Well caps also keep out insects, such as earwigs, which prefer a dark, damp environment to nest. Insects can cause major problems in a well. Bacteria levels can rise from their droppings, and sometimes the bugs themselves can get trapped in the wells, die, and decompose in the well water.

Does the well cap make my water safe?

Surface water can encounter many types of pollutants and transport them. These are not always easily detected by taste or smell. A properly sealed well cap is a safeguard in preventing those contaminants from penetrating the household water supply.

Having your well tested is the surest way to determine that the water is safe. Even if your well cap fits tightly on your well and your water tastes fine, the water well system should be given a checkup by a contractor every year.

Why should you have your well cap raised?

Well casings that extend above grade with a water tight well cap offer several advantages over buried water wells:

  • With the well head above ground and covered by a water tight cap; there’s significantly less chance of surface water intrusion into the potable water supply.
  • The well is easier to find (critical in a “no water” emergency).
  • The water tight cap also prevents varmint & insect intrusion.
  • Access is easier for general maintenance & inspection.
