minutes.

initial startup pressure reading.

once a week.
4. Performing a backwash procedure is required
once the pressure consistently reads 10 PSI
greater than the initial startup pressure, DO NOT
EXCEED 35 PSI.
5. Follow backwash and rinse procedure.

If after backwashing the filter you are unable to
get the pressure to lower sufficiently to ensure
operational pressures below 35 PSI you will need
to replace the filter sand.
