High pressure in your pool pump is often related to your filter system. Here's how to lower it:
Understanding the Problem
High pressure in your pool pump system usually indicates a blockage or restriction in the flow of water. Addressing this promptly is important to ensure your pump and filtration system function correctly and to prevent potential damage.
Common Solutions
Based on the provided references, here are the primary actions you can take:
-
Clean Your Filter: The most frequent cause of high pressure is a dirty filter.
- How: Backwash your filter if it's a sand or DE filter, or thoroughly rinse your cartridge filter.
- Why: A build-up of debris and contaminants reduces water flow through the filter, causing pressure to rise.
-
Change Filter Elements:
- When: If cleaning doesn't resolve the pressure issue, the filter media itself might be old and require replacement.
- How: Replace your sand, DE grids, or cartridge filter element according to the manufacturer's instructions.
-
Give Your Filters a Break:
- How: If your system runs continuously, reduce the running time of your pool pump.
- Why: Constant use can also contribute to filter issues and higher pressure.
Detailed Steps
| Step | Action | Why |
|---|---|---|
| 1. Assess Filter Type | Identify if you have a sand, DE, or cartridge filter. | The specific cleaning method differs for each type. |
| 2. Backwash (Sand/DE) | Follow your filter's backwash procedure. This reverses the water flow, forcing out accumulated dirt. | This is an initial, crucial step to remove debris from the filter media. |
| 3. Rinse (Cartridge) | Remove the cartridge and rinse it thoroughly with a garden hose. Avoid using high-pressure sprays. | This process removes most surface debris and ensures even water flow through the media. |
| 4. Inspect | Check for any damage or tears in the filter element after cleaning. | Damaged filters cannot clean efficiently. |
| 5. Replace Element (If Needed) | Replace filter media according to manufacturer instructions for long-term performance. | Failing to do so can cause the system to work harder, increasing the chance of damage or reduced functionality. |
| 6. Adjust Pump Runtime | Reduce the daily hours your pump operates. | Less run time allows the system to rest and improves its ability to function optimally. |
Example
If your pressure gauge reads unusually high (refer to your pool manual for normal range), start with a filter cleaning. If this does not resolve the issue, inspect the filter element. If cleaning and inspection do not improve the pressure you may need to replace the filter media.
