Pressure Gauge Reading on a Pool Filter Explained

Maintaining a swimming pool requires a lot of work and attention to detail. One of the most important aspects of pool maintenance is ensuring that the filtration system is functioning properly. The pressure gauge on a pool filter is a crucial tool to determine whether the system is working at optimum levels or not. In this article, we will explain what the pressure gauge should read on a pool filter, how to check it, and what to do if it is too high or too low.

Understanding the Pressure Gauge on a Pool Filter

The pressure gauge is a small, round dial that is in-built in the pool filter. It measures the pressure inside the filter and displays the readings in pounds per square inch (PSI). The pressure gauge is an essential tool for ensuring that your pool is clean and safe for swimmers. It indicates how well the filtration system is removing dirt, debris, and other contaminants from the pool water. Generally, when the pressure inside the filter increases, it means that the filter is working hard to clean the water. As the filter collects more dirt and debris, the pressure will continue to increase.

What Should the Pressure Gauge Read on a Pool Filter?

The ideal pressure gauge reading on a pool filter varies depending on the type of filter you have. For a sand filter, the pressure gauge should read between 10 and 20 PSI when the pump is running. If the pressure gauge reading is lower than 10 PSI, it means that the filter is not working efficiently, and if it is higher than 20 PSI, the filter is clogged and needs to be cleaned. For a cartridge filter, the pressure gauge should read between 10 and 15 PSI when the pump is running. If the pressure gauge reading is lower than 10 PSI, it means that the filter is not working efficiently, and if it is higher than 15 PSI, the filter needs to be cleaned.

How to Check the Pressure Gauge Reading on a Pool Filter

Checking the pressure gauge reading on a pool filter is a simple process that you can do yourself. First, locate the pressure gauge on your pool filter. It is usually located on the top or side of the filter tank. Once you have located the pressure gauge, make sure your pool pump is running. Then, look at the pressure gauge reading. If the reading is within the recommended range, then your filter is functioning correctly. If it is too high or too low, then further action is needed.

What to Do if the Pressure Gauge Reading is Too High

If the pressure gauge reading on your pool filter is too high, it means that your filter is clogged and needs to be cleaned. Here are the steps to follow to clean your pool filter:

1. Turn off the pool pump and filter system.

2. Open the filter tank lid and remove the filter element (either the sand or cartridge).

3. Rinse the filter element using a garden hose. For sand filters, use a sand filter cleaner to remove any organic materials from the sand.

4. Reassemble the filter and restart the pump and filter system.

5. After cleaning the filter, check the pressure gauge reading again. If it is still too high, you may need to replace the filter media.

What to Do if the Pressure Gauge Reading is Too Low

If the pressure gauge reading on your pool filter is too low, your filter is not working efficiently. Here are the steps to follow to troubleshoot the issue:

1. Check the water level in your pool. If the water level is too low, it can cause the pool pump to suck in air, resulting in a low-pressure reading on the filter gauge.

2. Check for clogs in the skimmer and pump baskets. A clog in these areas can restrict the flow of water to the filter, resulting in a low-pressure reading.

3. Check for obstructions in the pool returns. Any obstructions in these areas can cause the water to flow back into the pool without passing through the filter, resulting in a low-pressure reading.

4. Check the pool filter itself for any damage or wear and tear that may be affected its functionality.

5. If none of the above-mentioned steps works, it may be time to call a pool maintenance professional for further assistance.

Conclusion

In conclusion, ensuring that the pressure gauge on your pool filter is working correctly is crucial to maintaining clean and safe swimming pool water. Regularly checking the pressure gauge reading and keeping within the recommended range will prevent costly repairs and prolong the life of your pool filter. Remember, if the pressure gauge reading is too high or too low, take immediate action to troubleshoot the issue and fix any problems. With proper maintenance of your pool filtration system, you can enjoy a clean, refreshing pool all year round.
