I heard backyard pool filters can explode. Is that true?

The importance of pool filter cleaning and how to stay safe.

Yes. Many homeowners have pool filters that are not safely manufactured or parts have become worn and ineffective. These filters can explode and cause devastating injuries. The explosions happen when homeowners have cleaned their pool filters, reassembled the filter housing, and start up the pool pump. Even if done flawlessly injury can occur. 

Most filters are comprised of a tank, a lid, and a clamp that holds the system together. The filter operates under high pressure generated by a mixture of water and air. The lid can explode off the tank with tremendous force if too much pressure builds up and the clamp or bolt fails.

Because of the extremely high pressure that can build in the filter and result in an explosion, a failure can be catastrophic. We have seen cases in which the filter lid has damaged awnings and roofs, become lodged in trees, and damaged ceilings of pool sheds. When the lid of the pool filter hits a person, we have seen severe traumatic brain injuries, deaths, traumatic loss of eyes, and multiple broken facial bones.

How it works:

A swimming pool filter cleans water of debris. Generally, a filter comprises a two-piece tank – a bottom and a top – molded from heavy-duty plastic. The tank bottom holds a filter cartridge that cleans water as it passes through the system. A pump delivers water from the pool to the filter and back to the pool.

A filter tank can trap or accumulate air. The pump discharge compresses any entrapped air and pressurizes the filter. This creates a risk of explosion or “sudden separation” of filter parts. Filter manufacturers have known about the explosion risk since at least the early 1970s. In 1974, the United States Consumer Products Safety Commission (“CPSC”) published an article that reported “problems of exploding filter tanks.” Many pool filters that have similar problems are still in use today, a ticking time bomb in unsuspecting owners’ backyards.

How Long Has It Been?

It’s a good idea to have your pool filter cleaned at least every 2 - 3 months, more frequently depending on pool usage, wind + dust, landscape debris (leaves & dirt) that enters the pool, and if your pets enjoy the pool we recommend cleaning each month.

Safety Firs

Safety First!

After being cleaned, the tank has to be turned on and pressurized again, which is typically when the “explosions” happen without warning. The separation also tends to occur if the top of the filter does not perfectly sit on the bottom part when the filter band is applied and secured. The person cleaning the filter may believe that the seal is secure when actually, they have just set up a time bomb.

Healthy & Clean!

Healthy & Clean!

Bacteria, debris, and oils in your pool filter contaminate the water, leading to rashes, eye infections, or wound infections. Cleanmypoolfilter sanitizes your filter with each cleaning and conducts a Free bacteria test on your pool water.

Why Clean Your Swimming Pool Filtration System?

We all want our pool water to be healthy, clear, and clean. Filters are an essential component to maintaining a healthy, sanitary pool. They are designed to remove unwanted dirt, debris, calcium, and oils. Unfortunately, filters aren’t yet able to clean themselves. This means that someone needs to physically remove and clean inside your filter system. And unless you’re extremely handy with at-home DIY, electricity, plumbing, cleaning, and pool filtration systems, you’ll want to call the experts, that’s us!
