A properly functioning pool filter is essential for keeping your pool clean, clear, and safe for swimming. If you notice that the water in your pool isn’t as clean as it should be, you may begin to suspect that the filter is broken. But how can you know for sure, and what should you do about it?
One of the strongest indications that your pool filter is not working properly is if you clean the pool thoroughly, but the water soon becomes murky or filled with debris again. However, there are several different problems that could impair the filter’s performance—some of which may be easily resolved and others that could indicate that the filter needs to be replaced. For example, here are a few signs to watch for, aside from dirty water:
- Pressure problems. If the filter is dirty—or if the filter is too small for your pool pump—excessive pressure may build up inside the tank, thereby causing filtration problems. On the other hand, if the pressure is too low, water may not flow into the filter properly, which could impair circulation in the pool. Check to ensure that the pressure gauge on your filter gives a normal reading when the filter is running. See the owner’s manual for how to determine when it’s time to clean the filter.
- Filter leaks. If you hear dripping water or notice puddles around your filter, it’s likely that there is a leak. To try and identify the source, examine the tank for holes—if you find any, the filter will probably need to be replaced.
- Loud noises. If the filter system is emitting unusual noises, it could indicate that the motor on the pump is not functioning properly.
- Filter material leaking into the pool. If you have a sand or diatomaceous earth (DE) filter, it’s normal for small particles to pass into the pool. However, if you notice steady streams of particles seeping in, there may be a broken component in the filter.
