Pool Filter Troubleshooting Guide

There is no getting around the fact that every pool requires a functioning pool pump and pool filter. These components work in a ‘closed loop system’ to ensure clean, clear, and sanitary pool water. With the proper maintenance, pool filters can last for years, without sacrificing efficiency. Experiencing problems with your filter? Troubleshoot three of the most common issues below.

How Does It Work?

During normal operation, a pool pump draws water from the main drain and skimmers, generating pressure as it circulates water through various pool equipment. Before the water is returned to the pool, it passes through the filter, which effectively removes any remaining debris and contaminants. It then passed onto your pool’s heater, if applicable, and finally the chlorinator.

The three main types of filters are: sand pool filters, Diatomaceous Earth (D.E.) pool filters, and cartridge pool filters. Because there are pros and cons of each, it’s important to do your research, ensuring you make the right selection for your pool and budget. The job of pool filters is to keep your pool’s water crystal clear and free of debris, bacteria, and algae.

3 Common Pool Filter Issues

Why is my pool filter not filtering?

If your filter needs to be cleaned more once every one to three months, the problem could result from incompatibility between the pool and filter; the pool is too big for the filter or vice versa. Increased usage can also increase the number of cleanings needed. A more serious cause, warranting replacement, is a damaged filter or broken parts. You should have a pool service professional troubleshoot this problem.

Why is my pool filter leaking out the backwash line?

This is one of the most common problems pool owners encounter. That is a common symptom of a worn or loose gasket. If this is the case, you’ll need to replace the gasket. If the valve is the problem, a replacement may be needed, which depending on age may be covered under your system’s warranty.

Why does my pool filter run at a high pressure but with reduced water flow?

While no two filters will operate at the same pressure, if your filter rise 8-10 PSI over the clean starting pressure according to Hayward, it’s time to backwash or clean the filter. Always follow manufacturer directions when either backwashing or cleaning a filter. You may also benefit from a replacement cartridge. Other causes include algae and incorrect size.
