Why does my Bestway Lawn and Garden Equipment filter have excessive pressure?
- D
  Dylan FuentesAug 7, 2025
  If your Bestway Lawn and Garden Equipment sand filter exhibits excessive pressure, several factors could be responsible. The filter might be dirty, in which case you should backwash it. The sand bed may be calcified, requiring inspection and potential replacement of the sand. Insufficient backwashing could also be the cause, so continue backwashing until the water runs clear. Finally, the pressure gauge itself might be faulty and need replacement.

How to stop sand flowing to the pool from Bestway Lawn and Garden Equipment?

  Lisa MoyerAug 13, 2025
  If sand is flowing into your pool from your Bestway Lawn and Garden Equipment sand filter, several issues could be the cause. The sand might be too fine; it's recommended to use 0.45mm to 0.85mm #20 silica sand. Ensure you stop the sand filter each time you set the control valve. Also, the sand level could be too high; check that it's between the marked “MAX” and “MIN” on the collector hub. Lastly, the skimmer might be broken and require replacement.

  Sean JordanAug 19, 2025
  If you're experiencing no water flow in your Bestway Lawn and Garden Equipment, start by checking if the stopper plugs have been removed and the debris screens inserted. Ensure that any trapped air has been released. Verify that the control valve isn't set to the closed position; it should be set to the filter function. Also, inspect the strainer for blockages and clean it if necessary. If none of these steps resolve the issue, the sand filter may be broken and require professional service.

Why is the control valve leaking from port D on Bestway Lawn and Garden Equipment?
- C
  Christine HendersonAug 30, 2025
  If the control valve on your Bestway Lawn and Garden Equipment is leaking from port D, it could be because the control valve is set between two functions; set it to only one function. Alternatively, the gasket might be broken and needs replacement.
