An Easy Guide to Changing Laterals in Pool Filters

Swimming pools are a perfect way to relax and have fun with family and friends. Pools require maintenance to keep the water sanitary, clear and sparkling. One important part of pool maintenance is ensuring the filter is functioning optimally. Over time, the pool filter’s laterals may become damaged or worn, leaving the filter ineffective. Changing the pool filter’s laterals is a common maintenance task that can be done in a few easy steps. This article will guide you through the process of changing the laterals in your pool filter.

Why Laterals Need to be Changed

Laterals, also frequently referred to as fingers or cartridges, are vital components of the pool filtration system. They are slender plastic tubes that are placed inside a pool filter to ensure that water flows through the filter media, trapping and removing debris from the pool water. Over time, laterals can become dirty, corroded, or broken due to continuous exposure to water and chemicals. Damaged laterals may cause your pool filter to work less efficiently, and contaminants can seep through into the pool water.

Signs That Your Laterals Require Changing

Your pool filtration system water flow may decrease if laterals are damaged or clogged. You may see other signs of damaged laterals including:

- Cloudy or dirty Pool water: A clogged or damaged lateral may cause water to circulate through the filter inadequately, allowing debris to accumulate in the pool water.

- Pressure Gauge Readings: During a normal filter cycle, the water pressure gauge reads 5-10 psi. If this reading is higher, it may indicate that the laterals are clogged and need to be replaced.

- Inadequate back-washing: When laterals are damaged, proper backwashing will be challenging due to the clogs, thus leading to dirty or cloudy pool water.

Materials Required

Before beginning the process of changing out the laterals, you will need to gather the necessary tools and materials. These include:

- New Laterals: Buy the laterals that are compatible with your filter. It is important to check your filter's owner’s manual for the correct size, style, and number of laterals to purchase.

- Screwdriver or Wrenches: Depending on the type of filter and valve mechanism installed, you may need either a long-handled screwdriver or wrenches.

- Gasket Sealant: Purchase a silicone-based sealant to apply if necessary.

Steps for Changing Pool Filter Laterals

Step 1: Turn off the Pump

Before starting the lateral change process, shut off the pool pump system to reduce pressure in the filter system.

Step 2: Open the filter system and remove the old laterals

Unscrew the filter housing and remove the filter from the housing carefully. If your filtration system has a multiport valve, remove the drain plug in the bottom of the filter housing.

Remove the old laterals while being careful not to crack or break them.

Step 3: Add the new laterals and gaskets

Add the new laterals into the filter housing, ensuring that they are properly seated on the laterals’ hub.

Replace the O-ring gasket, and apply silicone sealant to ensure a proper seal.

Step 4: Close the filter and test the system.

After installing the new laterals in your pool filter, close the filter housing, reconnect the multiport valve to the pump, turn on the pump, and start the system.

Monitor the water pressure gauge and check for any leaks.

Conclusion

In conclusion, if you want to keep your swimming pool clean, clear, and healthy, changing the laterals in your pool filter is an important step to take. You can make this a regular part of your pool maintenance to ensure that your pool water is always sparkling and healthy. Replacing laterals requires some work, but if you follow the basic steps outlined in this article, you’ll be able to complete the process in no time. Remember, properly maintaining your pool filter helps extend the life of your swimming pool and makes it more enjoyable.
