For maintenance or repair it may be necessary to drain
water from the filter or completely remove all the sand
from the filter. The filter drain will allow for both water
removal and the flushing of sand.
Any additional piping installed at the water drain must
be removable in order to facilitate the further removal
of drain components. Allow sufficient space for the
flushing of sand from the filter. See
Figure 11
.
CAUTION
Be sure that all provisions for wastewater disposal
meet local, state or national codes. During any
backwashing or draining process, 100 gallons or more
of pool water will be discharged. Do not discharge
water where it will cause flooding or damage.
