Joining Two Sections

The Well Casing has a 4" long straight end (not corrugated) on each end of pipe. The one end is the same diameter as outside of pipe and the other end is a smaller diameter. Therefore the small end fits into the larger end and the pipe can only be joined at these straight ends. This bell and splicket joint is fastened together by using eight self-tapping plated #10 screws ΒΌ" diameter by 2" long. An epoxy sealant (Sika) can be used to obtain a water tight seal.


Slots

The Well Casing can be perforated with a 4" diameter tungsten carbide blade in a small skill saw as shown or various other blades can be used in an angle grinder. Thickness of blade shown is 1/16" but thinner or thicker blades are available. The average well is perforated from 2 ft. above the aquifer down to within 2 ft. of bottom of the well. Slots are cut in every second hollow as shown, four to six evenly spaced rows around pipe, depending on individual well conditions.

Well Cap

Well Caps are compression molded with smooth inner and outer surfaces to a uniform thickness of .430" on top and rim is .350" with a 1 3/8" inch crown on top. SRC (Sask Research Council, an Independent Testing Company) rated maximum vertical load of Cap to be 57640 lbs. Well Cap is secured with self tapping screws anywhere on pipe except on the small belled end. If you would like to view a copy of the SRC report click here (pdf).
