How to Drain Your Pool Filter Tank: Get Your Pool Back to Crystal Clear Water
If you own a backyard swimming pool, it’s important to maintain it regularly to ensure that the water is clean, safe and healthy for swimming. One of the most important aspects of pool maintenance is the pool filter. The filter’s job is to remove impurities and debris from the pool water to ensure that it’s sparkling clean. However, over time, the filter tank can fill with debris, dirt, and other contaminants that make it less effective. That’s why it’s essential to know how to drain your pool filter tank to keep your pool water crystal clear and free of impurities.
1. Why You Need to Drain Your Pool Filter Tank
Draining your pool filter tank is a necessary step in maintaining your pool water. The filter tank is where all the debris and contaminants caught in the filter cartridges or sand collect. Over time, this debris can clog the filter, reducing its effectiveness and compromising the quality of the pool water. Draining the tank is necessary to flush out the debris and contaminants and ensure that your filter continues to work efficiently.
2. When to Drain Your Pool Filter Tank
It’s recommended that you drain your pool filter tank at least once every six months, or more often if you notice that the water flow has become restricted, or if you’ve backwashed the filter excessively. You may also need to drain the tank if you’ve experienced heavy rainfall or a high volume of leaves and debris in the pool.
