How to Repair a Cracked Pool Filter Tank

A swimming pool is a great addition to any backyard, but it requires maintenance and repairs to keep it in good condition. One of the most common problems with a pool is a cracked filter tank, which can cause water leaks and reduce the effectiveness of the filter system. In this article, we will discuss how to repair a cracked pool filter tank.

What Causes a Pool Filter Tank to Crack?

A pool filter tank can crack for many reasons, including:

- Age: Over time, the plastic material of the filter tank can deteriorate and become brittle.

- Over-tightening: If the filter tank is over-tightened during installation or maintenance, it can crack.

- Freezing: If the pool is exposed to freezing temperatures, the water in the filter tank can expand and crack the tank.

- Pressure: If the pool filter is not cleaned regularly, the pressure inside the tank can build up and cause it to crack.

Before You Start

Before you attempt to repair a cracked pool filter tank, you need to assess the damage and determine if it is repairable. If the crack is severe or the tank is too old, you may need to replace the entire filter system. A minor crack can be repaired with a few tools and materials.

Materials and Tools Needed

- Epoxy putty

- Sandpaper

- Plastic welder

- Plastic patch kit

- Heat gun

- Screwdriver

- Wrench

Step 1: Drain the Filter Tank

The first step in repairing a cracked filter tank is to drain the water from the tank. Turn off the pool pump and release the pressure from the tank by turning the air release valve. You can then remove the drain plug to drain the water from the tank.

Step 2: Sand the Crack

Use sandpaper to sand the edges of the crack to remove any rough or jagged edges. This will make it easier to apply the epoxy putty.

Step 3: Apply Epoxy Putty

Apply the epoxy putty to the crack, making sure to fill the entire crack. Use your fingers or a putty knife to smooth out the putty and make it level with the surface of the tank. Let the putty dry and harden according to the manufacturer's instructions.

Step 4: Weld the Crack

If the crack is too large for epoxy putty, you can use a plastic welder to bond the cracked pieces together. Heat the welder and run it along the crack to melt the plastic and fuse the pieces together.

Step 5: Apply a Patch

If the crack is in a corner or a difficult-to-reach area, you can use a plastic patch kit to repair it. Cut a piece of plastic from the kit and place it over the crack. Use a heat gun to melt the plastic and bond it to the tank.

Step 6: Reassemble the Filter System

Once the repair is complete, you can reassemble the filter system. Replace the drain plug and turn on the pool pump. Check for any leaks or pressure issues before using the pool.

Conclusion

Repairing a cracked pool filter tank is a fairly simple task that can save you money and extend the life of your filter system. With the right tools and materials, you can repair most minor cracks easily. However, if the crack is severe or the filter system is too old, it may be time to replace it with a new one. Regular maintenance and care can help prevent cracks and other problems with your pool filter system.
