If the motor of your VEVOR Water Pump is running but no water flows through, it could be that air is entering the system. Check all hose/pipe connections and ensure the strainer lid is tightened. Another possible reason is that the suction height is too high or in an incorrect position, so position the system/pump to a lower place.
Why is my VEVOR HFP250A-10 Water Pump not cleaning the pool water well enough?
If your VEVOR Water Pump isn't keeping your pool water sufficiently clean, it could be due to several reasons. The pool chemistry might not be adequate to inhibit algae growth, so maintain proper pool chemistry. Also, check the sand bed depth and sand size, as an improper amount or wrong size can cause this issue. Finally, the turnover rate might be inadequate, so run the system for a longer time.
What to do if I notice higher filter pressure in my VEVOR Water Pump?
If you notice higher filter pressure in your VEVOR Water Pump, it could be due to insufficient back washing. Backwash until effluent runs clear. Alternatively, a partially closed valve or restriction in the return line might be the cause. Open the valve or remove any obstruction.
Why has the return flow to my pool diminished with my VEVOR Water Pump?
If the return flow to the pool is diminished when using your VEVOR Water Pump, there might be an obstruction in the pump. Disassemble and clean the pump. Another possible cause is an obstruction in the suction line, so clean the strainer or skimmer basket.
Why is sand flowing to the pool from my VEVOR HFP250A-10 Water Pump?
If sand is flowing into your pool from the VEVOR Water Pump, it could be because the sand is too small, the level of the sand is too high, or the under drain assembly is broken.
How to troubleshoot control valve function on a VEVOR HFP250A-10?
Regarding the control valve function of your VEVOR Water Pump, if the control valve is set between two functions, set the valve to the correct function. Alternatively, the gasket may be broken, in which case you should replace it.

The VEVOR Sand Filter Pump is designed to provide clear, sparkling water for swimming pools with minimal maintenance when installed, operated, and maintained according to the instructions provided. This manual covers two models: HFP250A-10 and HFP250A-12.
The sand filter pump utilizes special filter sand as a dirt-removing medium. Pool water containing suspended dirt particles is pumped through the piping system and directed by the filter control valve to the top of the filter tank. As the water passes through the filter sand, dirt particles are trapped, and the filtered water flows from the bottom of the filter tank, up through the standpipe, back to the valve, and then returned to the pool. Over time, accumulated dirt increases resistance to flow, indicating the need for cleaning (backwashing). During backwashing, the water flow is reversed, directing water to the bottom of the tank, up through the sand, and out through the waste line, flushing out trapped dirt and debris. After backwashing, the control valve is manually resequenced to "Rinse" and then "Filter" to resume normal operation.
