Next I cut and glued up all
the PVC pipe. For the supply line that ran from the well to the
heat pump, one inch PVC was used. To go from the heat pump to the
three injection wells, 1 1/4 inch pipe was utilized. A couple of
minor bumps were encountered. A sprinkler head and a sprinkler
line turned out to be in the planned path of the PVC. Other than
that, it went smoothly. Not particularly fast, but smoothly.
After a couple of days of cutting and gluing with numerous extra trips
to Lowes for PVC fittings, it was done.
Here are some pictures.
The first two show the detail of the 1 1/4 inch pipes going to the injection
wells. You can see two pipes in the main trench. The pipe on
the bottom is the one inch supply line. The pipe on the top is the 1 1/4
inch drain returning from the heat pump.
Above is a better view of where
I didn't fill in the annular space with cement. Dumb, dumb, dumb.
In the next two pictures you can see
the branches going to all three injection wells. You can see the supply
well on the right. A few years ago, in anticipation of geothermal, I had
put in a one inch supply line from the well to the area where the injection
wells were drilled. That was one small part of the yard I didn't have to
In the photo above, the old heat pumps are on the left
in the distance. A sprinkler line was in the originally planned path of
I filled in the trenches with
topsoil. More about that in Part 3...
