To remove pressure from a sand filter (likely meaning to address high pressure readings), the primary method is to clean the filter, typically by backwashing.
Here's a breakdown:
-
Cleaning the Filter: The initial step to address high pressure is to clean the filter.
- For a sand filter, this usually involves backwashing. This reverses the flow of water to flush out accumulated debris.
-
What to do if Pressure Remains High:
- According to a reference, "If the pressure gauge continues to read high after you've cleaned the filter, something isn't working right."
In summary, the main way to remove pressure, indicated by a high-pressure reading, from a sand filter is to backwash it. If backwashing doesn't resolve the high-pressure issue, further troubleshooting is required to identify the underlying problem.
