Standard well caps like these are simple installations. Simply remove the vent cap and insert the probe. The probe fits perfectly in a standard 1/2 or 3/4 threaded pipe connection and gives a great tight seal.

Make sure that the well cap is securely fastened and that any other openings are sealed.

This installation was not giving reliable readings because the user did not seal the top of the well prior to testing. Remember that it is necessary to close the openings around the tubes and wires. The openings can be blocked with nearly anything that prevents the air from easily moving in and out of the well. Cardboard, duct tape, or even rags stuffed into the holes can do the job.

If sealing the well is not an option a sounding tube could also be used. A continuous length of 1/2″ or 3/4″ PE tubing could be fed into the well to below the low water line and left sticking out of the top of the well slightly for the well sounder. This would provide a stable and noise resistant path for the sound pulse.

The Well Watch and Well Sounder meters need access into the casing through the well cap. In regions that are prone to freezing the well is often outfitted with a pitless adapter and turtle cap, instead of a sanitary seal. These wells can still be measured with our sonic meters by drilling a hole to fit at least a 1/2″ pipe thread in the turtle cap. This will allow the tapered nozzle of the probes to sit firmly in place. If you prefer not to drill the existing well cap, we offer a predrilled threaded replacement

If the well is outfitted with a spool type pitless adapter then a sounding tube will need to be utilized to get past the spool, otherwise the spool will create too much of a blockage to get a good reading of the water levels. If using, the sounding tube needs to reach from the tip of the probe down to the access hole in the spool. The microphone tube of the Well Watch will also need to be extended the same distance. This will allow for accurate readings with either type of pitless adapter setup.
