What do skimmers do for your pool?

When you start a pool pump, the skimmer pulls water and floating debris from the pool surface through a butterfly valve called a weir, then collects them in the skimmer basket after passing through the weir.

The butterfly valve on the pool pump returns to its original position when the pump is turned off, which prevents debris from returning to the pool.

The skimmer baskets in this phase collect debris from the pool surface, ensuring maximum filtration capacity and free flow of water.

Why does the suction power weaken?

Let’s list some of the problems that cause pool skimmer suction to weaken and ways to repair low suction power in pool skimmers.

Importance of the correct water level

Flow into the inlet of the pool skimmer must be high enough that no air is present. Most of the pool’s skimmers move about an 1/8 inch into the water. It will help skimmers to remove debris and chemicals properly.

But, when the weather is warm and sunny, too much water may evaporate from the pool, so it may need to be refilled.

In torrential rain, water levels rise abruptly above the skimmer opening. And in this way skimmer does not work at all.

You may notice that leaves are floating or near the skimmer when the water level in your pool is too high. If the water is too high, drain the pool until the water is the skimmer line.
