But if you’re not testing for plumbness and alignment—and you’re installing municipal, industrial, or irrigation wells with lineshaft turbine pumps—you’re making a big mistake.

If you’re primarily drilling domestic wells or other small-diameter, shallow wells, it’s not likely a small deviation in plumbness or alignment will cause problems. However, on deep wells or wells to be equipped with lineshaft turbine pumps, the plumbness, straightness, and alignment of the well is extremely important to the operation of the pumping equipment.

“If a lineshaft turbine pump is out of alignment, it will start to vibrate; the bushings will start to wear,” Hix says. “Then, once they wear too much, the drive shaft starts to wobble and shake. It wears out the pumping equipment too fast.”

Plumbness and alignment may be less of an issue with submersible pumps, but misalignment can cause the pump to lie against one side of the casing, resulting in excessive wear. If the casing is in contact with a hot motor, it can also cause PVC casing to melt or become deformed.

“The pump always goes in easier than it will come out,” Hix says. “When you’re lowering it down, it will glide and follow the casing. But then you lift it up, it will want to go in a straight line. Now, you’re really dragging through the misalignment areas.”

For wells greater than 10 inches in nominal diameter and/or equipped with a lineshaft turbine pump, the National Ground Water Association’s NGWA-01-14 Water Well Construction Standard recommends the maximum allowable horizontal deviation of the well from the vertical not exceed two-thirds times the smaller inside diameter per 100 feet, tested to the depth of the expected pump installation.

Alignment—according to NGWA’s standard—should be such that a 40-foot-long dummy pipe can pass freely through the casing to the depth of the expected pump installation.

Maximum allowable horizontal distance between the actual well centerline and a straight line representing the proposed pump centerline shall not exceed one-half of the difference between the inside diameter of the casing and the desired maximum outside diameter of the proposed pump to be installed.

One simple way to test for alignment is to complete a dummy test. Lower a 40-foot-long pipe into the hole to where the pump is going to be set. If it freely goes to that point and you can pull it back out again, the well passes.

The results will tell you how large the diameter of the pump can be and how deep you can set the pump without bending. So, if the well owner would want to install a larger-diameter pump or set the pump deeper, the information will be available.

“What if in 10 to 20 years they want to set the pump lower?” Renner says. “If the bottom of the well is crooked, they’ll have a problem. You’d have to tell the owner the pump they just spent $50,000 for can’t go in the hole.”

That’s why Hix recommends contractors complete plumbness and alignment tests—particularly for wells with lineshaft turbine pumps—even if it’s not required for acceptance. He compares it to doing a video log of a well to preserve what it looked like at completion. You’ll always have the plumbness and verification results in your files in case something comes up down the road.

Using the language python, I created a game of blackjack played in the terminal, giving the user and the computer two numbers, and both players try to get as close to 21 as the can by getting more cards or staying with the cards they were dealt.
