How High to Fill a Pool?

The correct water level for a pool is typically based on the position of the skimmer.

Based on the provided reference, your pool water level should reach one third to one half of the way up the pool skimmer's opening. This is the optimal range for the skimmer to operate efficiently.

Why the Skimmer is Your Guide

The pool skimmer is a crucial part of your pool's filtration system. It's designed to pull water from the surface, capturing debris like leaves, bugs, and other floating particles before they sink to the bottom. For the skimmer to work effectively, the water level needs to be within a specific range relative to its opening.

The Ideal Water Level Range

Setting the water level correctly ensures proper water flow through the skimmer and into your filter and heater.

• Recommended Range: One third to one half of the way up the skimmer opening.
• Reasoning: A pool skimmer is most efficient when covered halfway with pool water, according to the reference. This range allows for optimal surface debris removal and prevents air from being sucked into the system.

Consequences of Incorrect Water Levels

Maintaining the water level within the recommended range is important for several reasons:

• Water Too Low:
  • The skimmer will suck in air.
  • This can cause the pump to lose its prime.
  • The pump may overheat and potentially burn out.
  • Poor water circulation and filtration.
• Water Too High:
  • The skimmer opening is fully submerged or too low in the water.
  • Reduces the skimmer's ability to effectively draw in surface debris.
  • Floating debris may simply bypass the skimmer opening.

Practical Tips for Maintaining Water Level

Keeping your pool water level within the ideal range requires occasional monitoring and adjustment.

• Check Regularly: Especially during periods of high evaporation (hot weather, windy conditions) or after heavy use.
• Add Water: Use a garden hose to fill the pool until the water level is between one-third and one-half up the skimmer opening.
• Remove Water: If the level is too high (e.g., after heavy rain), you may need to drain some water using a submersible pump or the pool's main drain/filter system if it has a waste setting.
• Be Mindful of Activity: Splashing and evaporation naturally lower the water level over time.

Here's a quick summary table:

By keeping your pool water level properly aligned with the skimmer, you ensure your filtration system runs smoothly, keeping your water clean and your equipment protected.
