How to Adjust the Pressure on an Inground Pool Sand Filter

Adjusting the pressure on an inground pool sand filter is an essential task for maintaining your pool's cleanliness and ensuring that it operates efficiently. Here is a step-by-step guide on how to adjust the pressure on an inground pool sand filter:

Step 1: Turn off the Pool Pump
The first step is to turn off the pool pump. This ensures that no water is flowing through the filter during the adjustment process.

Step 2: Locate the Pressure Gauge
The pressure gauge is typically located on the top of the filter tank. It measures the pressure inside the filter tank and displays it in pounds per square inch (PSI).

Step 3: Read the Current Pressure
Read the current pressure on the pressure gauge. It is essential to know the starting pressure before making any adjustments.

Step 4: Backwash the Filter
Backwashing the filter is necessary before adjusting the pressure. This process ensures that any debris or dirt is removed from the filter tank, allowing for accurate pressure readings. Follow the manufacturer's instructions for backwashing your specific filter model.

Step 5: Rinse the Filter
After backwashing, rinse the filter for about 30 seconds to remove any remaining debris or dirt.

Step 6: Turn on the Pump
Turn on the pool pump and let it run for a few minutes to allow the filter to settle.

Step 7: Read the Pressure
Read the pressure on the pressure gauge after the filter has settled. The pressure reading should be between 8 and 10 PSI above the starting pressure.

Step 8: Adjust the Pressure
If the pressure reading is too low, it means that the filter is not working efficiently, and you need to adjust the pressure. To increase the pressure, turn the valve handle clockwise. To decrease the pressure, turn the valve handle counterclockwise.

Step 9: Rinse the Filter Again
After adjusting the pressure, rinse the filter again to remove any debris or dirt that may have accumulated during the adjustment process.

Step 10: Monitor the Pressure
Monitor the pressure regularly to ensure that it stays within the recommended range. If the pressure is consistently too high or too low, it may indicate a problem with the filter or pump that requires professional attention.

In conclusion, adjusting the pressure on an inground pool sand filter is a simple process that can be done by following these ten steps. Regularly monitoring the pressure and adjusting it when necessary is crucial for maintaining a clean and efficient pool.
