Expert Q&A: Why Is Sand Still Coming Out of My Pool Jets After Replacing the Lateral Lines?

Understanding the Issue of Sand in Your Pool Jets Post-Lateral Replacement

If you’ve recently had your pool’s lateral lines replaced and are noticing sand coming out of the jets, you’re likely concerned about what this means for your pool’s condition and maintenance. This is a common question among pool owners seeking to ensure their filtration system functions optimally.

Possible Causes of Sand in the Jets

Residual Sand in the Filter System: During the lateral replacement process, some sand particles may have been dislodged and temporarily circulated through the system.
Incomplete Backwashing or Rinsing: If the filter hasn’t been properly backwashed or rinsed after the repair, residual sand can remain and eventually exit through the jets.
Incorrect Filter Media Installation: Using the wrong type or improperly installing the filter media can cause sand to escape into the pool water.
Wear or Damage to the Filter System: Any cracks or damage to the filter housing might allow sand to bypass the filtration media and exit via the jets.

Steps to Resolve the Issue

Perform a Thorough Backwash: Initiate a complete backwash cycle to remove loose sand particles from the filter system.
Rinse the Filter: Follow the backwash with a rinse cycle to settle the media and remove residual debris.
Check the Installation: Verify that the lateral lines and filter media are installed correctly according to manufacturer specifications.
Inspect the Filter Housing: Look for cracks, leaks, or damage that could be causing sand to bypass the filtration system.
Run the Pump and Monitor: Operate the pool pump and observe the water flow, ensuring no excessive sand is being discharged.

When to Seek Professional Help

If after following these steps the problem persists, or if you’re unsure about performing these procedures yourself, it’s advisable to consult a professional pool technician. They can inspect the system thoroughly, identify underlying issues, and ensure your pool’s filtration system is functioning correctly.

Preventative Maintenance Tips

Regularly backwash and rinse the filter as recommended by the manufacturer.
Periodically inspect the filter and lateral lines for damage or wear.
Use the appropriate filter media and replace it according to the maintenance schedule.
Keep debris out of the pool to reduce strain on the filtration system.
