How to Drain a Pool Using the Main Drain?

Published in Pool Maintenance 2 mins read

To drain your pool using the main drain, follow these steps carefully, ensuring your pool system is off for safe operation.

Steps to Drain Your Pool via Main Drain

Here's a structured guide based on the information provided:

Step Action Details
1 Turn Off Pool System: Make sure the pump and any other automated system is completely off. Safety first!
2 Open Backwash/Drain Line: Locate your backwash valve or the dedicated drain line for your pool setup and open it. This is where the water will be expelled during draining.
3 Close Off Skimmer Lines: Using plugs or valves on the suction side of your pump, block all water intake from the skimmer(s). This ensures water is pulled only from the main drain.
4 Verify Main Drain Suction: Ensure that the pump will be drawing water only from the main drain. If you have a valve system, verify the line coming from main drain is open.
5 Turn On Pool Pump: With the drainage path and water source secured, turn on the pool pump to begin the water draining process.
6 Monitor Water Level: Check the water level periodically during drainage to ensure it is lowering as expected. Once the pool is drained to the level you want, turn off the pump.

Key Points for Safe and Effective Draining

  • Safety: Always turn off the pool system before starting this process.
  • Clear Path: Double-check that the backwash or drain line is clear and ready for water discharge.
  • Suction Control: Verifying water is only coming from the main drain is crucial for this method to work effectively.
  • Monitoring: Don't leave the system unattended; keep an eye on the draining process to avoid over-draining.

This method provides a controlled way to drain your pool, specifically using the main drain as the suction source as per the reference.
