BACKWASHING
When the return flow diminishes and your filter pressure gauge reads 10 psi higher to double
the normal starting pressure it is time to backwash. The actual time between backwashing will
vary depending on the amount of dirt in the pool and clarity of the water; on average you may
expect to backwash every 10 days to 2 weeks.
When it comes to backwashing, more is NOT better. As dirt accumulates inside of
the filter tank it is actually able to filter smaller particles. Backwashing too frequently
will decrease your filter’s efficiency.

Sand should be replaced every 1 to 2 seasons. When replacing sand use only swimming pool
filter quartz referred to as #20 silica sand. DO NOT use play sand. When replacing sand be
careful of the bottom laterals (slotted tubes) at the bottom of the filter tank. Check laterals for
cracks and replace if necessary.
