If your Well Wizard system was ordered with bulk tubing, it will be necessary to measure the
tubing length in the field or to install the pump using tubing known to be longer than the well
depth, cutting the tubing off when the pump is at the desired depth. Below are instructions for
connecting the tubing to each pump model.
Pumps with compression style fittings – 1100 and 1200 Series models
1. Separate the ends of the twin-bonded tubing about 8-12 inches (20-30 cm).
2. These pumps use a discharge fitting that is taller than the air fitting connection. Shorten the
length of the discharge tubing by measuring the difference between the fitting heights and cutting
off this amount from the discharge tubing. Alternately, you can insert the air tubing into the fitting
and then cut off the appropriate length of the discharge tubing, generally to the center of the fitting
height. It’s best to test fit the tubing for length before tightening the fittings.
3. If the discharge tubing is 3/8” O.D. or larger, or if it has a Teflon lining, you must use a tubing
insert. Push the insert into the tubing before inserting the tubing into the fitting.
4. Loosen the nut-and-ferrule assembly and push the air supply tubing into the matching fitting on
the top end of the pump.
5. Tighten both fitting nuts finger tight.
6. For each fitting nut, hold the fitting base with one wrench and the fitting nut with another wrench,
then tighten the fitting nut one additional turn.
Pumps with barb style fittings – 1000, 1300 and 1500 Series models
1. Separate the ends of the twin-bonded tubing about 8-12 inches (20-30 cm).
2. For pumps that have staggered height air and discharge fittings, shorten the length of the
discharge tubing by measuring the difference between the fitting heights.
3. Place the stainless steel pinch clamps onto the ends of the air supply and discharge tubing
BEFORE pushing the tubing onto the barbs.
4. Install each tubing by pushing it over the barb fittings as far as possible, and then position the
clamp over the barb and tightening the clamp with the pinch clamp tool.
Cut Bulk Tubing to Length
Measuring tubing length can be difficult under field conditions. Some users prefer to attach the pump to a
bulk tubing spool that is known to be longer than the well depth and then cut off the tubing when the pump is
installed to the desired sampling depth. However, this approach requires having more tubing that required for
the desired sampling depth. To determine the desired pump position, follow these steps:
1. Before using this method, check the well construction log or other documentation to determine if
there is a “tailpipe” or sediment trap installed below the well screen. If so, it’s recommended to
sound the well bottom depth before installing the pump system.
2. Lower the pump into the well until the pump touches the bottom of the well.
3. To position the pump at the middle of the well screen, where the screen extends upward from the
bottom of the well and the length of the screen is known, pull the pump up by half of the screen
length and mark the depth.
4. For low yield wells and/or wells with short water columns, raise the pump up at least 12 inches
(30 cm) from the bottom and mark the depth.
