how to remove spider gasket for pool filter

Author: PoolKing - Pool Sand Filter Manufacturers

The spider gasket is an essential component of a pool filter, preventing water from bypassing the filter and keeping the filter operating efficiently. Over time, the gasket can become worn or damaged, resulting in leaks or reduced filtration performance. When this occurs, it's necessary to remove the old gasket and replace it with a new one. In this article, we'll walk you through the process of removing a spider gasket from a pool filter.

What is a Spider Gasket?

A spider gasket is a small, circular rubber seal located in the valve assembly of a pool filter. The gasket sits inside a multiport valve, which controls the flow of water through the filter. When the valve handle is turned, the spider gasket is responsible for sealing off the individual ports, redirecting water flow, and preventing leaks.

Why Remove a Spider Gasket?

Over time, the spider gasket may become brittle, crack or become damaged, resulting in leaks or reduced filtration performance. If you notice that water is bypassing the filter or leaking out of the valve assembly, it may be time to replace the spider gasket.

Tools Needed:

- Screwdriver

- Socket Wrench

- Replacement Spider Gasket

- Lubricant

Step 1: Shut Off the Pump

Before you begin, ensure that the pool pump is switched off. This will prevent water from flowing through the multiport valve and allow you to work safely without getting wet.

Step 2: Remove the Multiport Valve

Remove the screws or bolts holding the multiport valve in place using a screwdriver or socket wrench. Carefully lift off the valve assembly, taking care not to damage the filter or the plumbing connections.

Step 3: Remove the Old Gasket

The spider gasket is located on the underside of the multiport valve. Gently lift out the old gasket, taking care not to damage the valve or the gasket seat. If the gasket is stuck in place, you may need to use a screwdriver or other tool to pry it loose.

Step 4: Clean the Gasket Seat

Before installing the new gasket, clean the gasket seat. Use a clean cloth and a mild detergent to remove any dirt or debris that may be present. This will ensure a tight seal when the new gasket is installed.

Step 5: Install the New Gasket

Carefully place the new spider gasket onto the gasket seat, ensuring that it is fully seated in place. Apply a small amount of lubricant to the gasket surface to make it easier to slide into position.

Step 6: Reinstall the Multiport Valve

Replace the multiport valve, making sure that it is seated properly on the filter. Tighten the screws or bolts in a criss-cross pattern to ensure an even and secure fit.

Step 7: Turn On the Pump

Once the valve is securely in place, turn on the pool pump to test for leaks. If you notice any leaks, turn off the pump and recheck the installation of the gasket.

Conclusion

Removing a spider gasket from a pool filter is a straightforward process that can usually be completed in less than an hour. By following the steps outlined in this article, you can ensure that your filter is operating optimally and that your pool is free of leaks. Remember to perform routine maintenance on your pool filter to ensure that it continues to operate efficiently for years to come.
