Why Is My Pool Filter Overflowing?

Having a backyard pool to spend the hot summer days in is a luxury that many people enjoy. However, it also comes with responsibilities like cleaning and maintaining it regularly. One essential part of maintaining a swimming pool is ensuring that the pool filter is functioning correctly. If you're experiencing an overflow from your pool filter, it's a sign that something is amiss. Here are some reasons why your pool filter may be overflowing and how to remedy the situation.

1. Improper Backwashing

Backwashing is a crucial step to keep your pool filter clean and running efficiently. However, overdoing it can cause an overflow. When you backwash, the dirty water goes out of the waste valve, and clean water returns to the pool. If you backwash too long or too often, the pressure relief valve can't handle the volume of water, leading to an overflow. To avoid this, use a pressure gauge to determine when to backwash and don't overdo it.

2. Dirty or Damaged Pool Filter Cartridge

If your pool filter cartridge is dirty or damaged, water filtration won't be as effective, leading to clogged pipes and, eventually, an overflow. Cleaning your filter cartridge regularly and replacing it every three to five years is vital in avoiding an overflow. You can clean the filter cartridge by taking it out of the filter unit and rinsing it under a high-pressure hose. Be gentle, don't use any chemicals and remember to wear gloves.

3. Clogged Skimmer

The skimmer is the part of the pool that takes in water and filters out debris. If the skimmer is clogged, it won't let water through, leading to an overflow. To remedy this, remove the basket and clean out any debris or leaves, making sure to wear gloves and use a skimmer net to pick out any unwanted growth or small debris.

4. Electricity Supply Issues

The pool filter relies on electricity to function correctly. If there is a power outage or a problem with the power supply, the filter may not be able to regulate water flow and cause an overflow. Check if the electrical supply to the filter is working correctly and, if not, seek professional help.

5. Incomplete Plumbing Layout

If there is a plumbing leak or something is not installed correctly in the pool's plumbing system, water flow can be hindered, leading to an overflow. Have a professional inspect your pool system to ensure that everything is correctly installed and working as it should.

In conclusion, an overflowing pool filter can be a significant headache for pool owners. However, it isn't all doom and gloom, and there are things you can do to fix the problem. Keep in mind the five reasons above and take the necessary steps, such as regular maintenance or seeking professional help, to avoid an overflow.
