Water Well Service Guidelines
Serving Orono & Minneapolis, MN
GUIDELINES FOR AN EXCELLENT PRIVATE WATER SYSTEM

LOCATION: The well should be located in an area that is easily accessible for future well work, but also in a safe location so the well will not be hit by cars, snow plows, etc. The top of the well should be 12” above ground after final grade has been done to prevent groundwater runoff from entering your well. The well location must comply with state regulations.

WELL SCREEN: Proper placement of the screen is determined by the driller and is set in the most porous ground material. The advantage of screen over slotted pipe is that a screen allows better water flow into the well and does not plug up as easily. T.L. Stevens Well Company installs screens, not just slotted pipe or smaller 2” screen.

WELL DEVELOPMENT: After the well has been completed it must be developed to get the best possible performance. Developing is usually done by airlifting and high pressure jetting the well. This procedure forces loose sand, mud, and gravel to the surface; leaving the bottom of the well clean from debris that could plug the screen and restrict water flow into the well. T.L. Stevens Well Company will develop your well for as long as needed to produce the best possible water quality and quantity.
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.

PUMPS: The size of your pump is determined by a combination of factors; well production, water usage, drop pipe size, static water level and pressure needed. Biggest is not always best. A knowledgeable well company will install the correctly sized pump for the application. If the pump is undersized you will have low water volume, low water pressure and the pump will not last long because it is constantly being overworked. If the pump is oversized, it will start and stop too often. Cycling too often will cause failure to electrical components (fuses, switches, contacts, etc.) much faster. The power usage is greater and the life expectancy of an oversized pump decreases. It will also waterhammer (sudden pressure spikes) which is hard on the pump and plumbing. T.L. Stevens Well Company installs the most efficient pump for the job.

PLUMBING: All plumbing should be properly sized and neatly installed. RO lines for a future system can be installed.

PRESSURE TANKS: The pressure tank should be sized properly for the water system. A tank which is too small will cause the pump to start/stop too much and reduce the life expectancy of your pump. A tank which is too large is not necessary, will waste installation time, take up more space in the utility room and the tank will cost more without serving any real benefit. Your water will not be as fresh because more water is held in a larger tank.
