4. Subtract five feet from the depth of
your well. This is the total length
of PVC pipe and couplings to
cement onto both 1-1/4" male and
1" female PVC adapters. Cement
a section of PVC pipe to each
adapter, then lower the whole
assembly into the well, foot valve
first. Firmly clamp the end of the
PVC pipes with a pipe clamp to prevent the assembly from
sliding down into well.
