Know When to Replace Your Inground Pool Skimmer Box

If you own an inground pool, it’s crucial to keep your pool skimmer box in good working condition. The skimmer box is responsible for removing debris and leaves from your pool, preventing them from clogging your pool’s filter system. Over time, wear and tear on your skimmer box can cause cracks, leaks, and other damage. If you notice that your pool isn’t as clean as it used to be, or if you see visible damage to your skimmer box, it’s time to consider a replacement.

One important sign that your skimmer box needs to be replaced is a loss of suction. If you notice that your pool’s suction isn’t as strong as it used to be, it’s likely that your skimmer box is clogged, damaged, or has a leak.

Another thing to look out for is visible damage to your skimmer box. If you see cracks or other signs of wear and tear, it’s likely that your skimmer box is no longer functioning as it should be.

If you’re not sure whether your skimmer box needs to be replaced, you can perform a simple test. Turn off your pool’s pump and remove the skimmer basket from the box. Fill the skimmer box with water and observe the water level for several hours. If the water level drops significantly, it’s likely that your skimmer box has a leak and needs to be replaced.

Ultimately, replacing your inground pool skimmer box is an important maintenance task that can help keep your pool clean and functioning properly. By knowing when to replace your skimmer box and taking action promptly, you can ensure that your pool stays in great condition for years to come.

Step 1: Locate your pool’s main electrical panel. It’s usually located near the pump and filter system.

Step 2: Turn off the circuit breaker that controls the power to your pool. This may be labeled as “pool” or “pool equipment”.

Step 3: Double-check that the power is off by using a non-contact voltage tester. Simply hold the tester near the electrical panel, and it will indicate whether or not there is any electrical current present.

Remember to never work on your pool’s electrical components without turning off the power supply first. Taking this precaution can prevent serious injury or even death.
