If you’re like most pool owners, you rely on your filter to keep your water clean and clear. But what do you do if your filter stops working properly? Here are a few tips on how to repair pool filter:

- Check the filter pressure. If the pressure is too high or too low, it may be causing the filter to malfunction.
- Clean or replace the filter cartridge. A dirty cartridge can cause the filter to work improperly.
- Check the pump motor. If the motor is running hot, it may be causing the filter to malfunction.
- Inspect the plumbing for leaks. A leaky pipe can cause the filter to work improperly.
- Check the water level. If the water level is too low, it can cause the filter to malfunction.
If you can’t find the source of the problem, it may be time to call a professional.
