Why Maintaining Proper Pressure is Important

Maintaining proper pressure in your pool filter is crucial for keeping your pool clean and healthy. A pool's filtration system is responsible for removing debris, bacteria, and other contaminants. If your filter is not functioning properly, your pool water can become cloudy, green or even trigger skin and eye irritation. It is recommended that pool owners aim for a pressure reading of 10-15 psi for optimal filtration.

Clogged Filter or Pump Basket

When a pool filter loses pressure, one of the first things to check for is a clogged filter or pump basket. Dirt, debris, and other materials can accumulate in your filter, causing it to become clogged, which reduces flow and pressure in the filter. Similarly, your pump basket can become clogged with leaves and debris which leads to decreased water flow and pressure within the system. Regular cleaning of your filter and pump basket is necessary to prevent blockages, and remember to replace between every few months to every year, depending on filter type.

Leaks in the System

Another common cause of reduced pressure is leaks in the pool system. Leaks can occur in various parts of the system, from the pool pump to the filter to the pool skimmer or return jets. Even minor leaks can drastically decrease the pressure in your pump and filter. You can check for leaks by inspecting the pool equipment, as well as examining the area around the pool pump, the valves, and any connections. Also, keep an eye on the pool water level, if it drops faster than usual, this could be related to a leak.

Inconsistent Water Levels

Water levels may also be a cause for concern. If the water in your pool is too low, the pump may become clogged with air, leading to decreased pressure. To avoid this, monitor your pool's water level and add water as needed to maintain a proper level.

Damaged or Worn Out Parts

Lastly, worn-out or damaged pool parts can lead to a loss of pressure. Parts such as o-rings, seals, and gaskets can fail over time and require replacing. If you think you notice any damaged or worn parts, it's important to replace them right away to prevent any further damage.

In conclusion, low pressure in your pool filter is a common issue among pool owners. When you encounter this problem, start by checking for clogged filters or pump baskets, leaks, water levels, and worn-out parts. If none of these solutions work, it might be time to consult with a professional pool service company to help identify the problem and find a solution. Keep investing in the maintenance of your pool to keep it clean, healthy and enjoyable for years to come.
