Bestway Sand Filter Pumps

Only a screwdriver is necessary to assemble the Sand Filter.

No, the swimming pool should not be used when the sand filter is operating.

Open the strainer cover, remove the O-ring and apply petroleum jelly or Vaseline over the O-ring, replace the O-ring and cover back. If this does not help, please contact your local Bestway After Sales Service point to get instructions.

No. Playground sand and beach sand or similar contain impurities and their grains size is not uniform.

The recommended size of sand for Bestway Flowclear Sand Filter is from 0.45mm to 0.85 mm. The most common type is Silica #20, which is available from pool suppliers and many mass merchandisers. Using the incorrect size of sand will cause the system to malfunction and void its warranty.

Under normal operating conditions, sand should be changed in residential filters every 4 to 5 years. In areas with high air contaminants such as dust, leaves or any condition that requires frequent back washing, the sand may need to be changed every 2 to 3 years.

If the pressure reading on the pressure gauge is 0.045 MP (6.5 PSI) or higher or the water flow to the pool is too low it could be the time to clean the sand. Please check the following:

If there is any blockages in the hoses

If the connection valves are closed or partially closed

After having checked the above conditions, please follow the instructions on the manual to perform backwash and rinsing. If after having performed them, there is still a high-pressure reading, sand bed replacement is necessary.
