GROUTING THE WELL:
Proper sealing around the well is accomplished by forcing a sealant between the drilled hole and the outer well casing to keep the water from becoming contaminated. If this is not properly done, water can travel down the outside of the well casing into the aquifer and can contaminate the well water with nitrates, bacteria and other pollution from ground water runoff.
PITLESS UNIT: A pitless unit is made of steel and extends from 1’ above ground to 5' below ground. Its purpose is to make a sealed, sanitary, frost-free, water tight connection between the well and the house and to keep the waterline from freezing. With a pitless unit the water flows from the well to the house below the frost line. Since the unit is made from steel, it is stronger and better protects the well head. T.L. Stevens Well Company installs pitless units while other well companies may use pitless adapters.
A pitless adapter serves the same purpose as a pitless unit, but it is mounted directly onto the PVC well casing. When a pitless adapter is used, it is the PVC well casing that extends 1’ above ground. This PVC well casing is vulnerable to UV sunlight which will break down the plastic and may eventually weaken it, thus causing well repair to be needed. The adapter is also more prone to leak.
WATERLINE & WIRE: The waterline to the house should be 160# poly pipe. 100# poly pipe is weaker and more vulnerable to damage. 12 gauge UF wire should always be used. Never use 14 gauge NM-B household wire because it is not designed for underground applications. All underground fittings should be brass. Galvanized fittings will corrode and eventually leak. Brass fittings will not. T.L. Stevens Well Company uses 160# poly pipe, 12 gauge UF wire and all brass fittings underground, whereas other companies may use inferior material.
