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

Yes. Many homeowners have pool filters are not safely manufactured. These filters can explode and cause devastating injuries.

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 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 1970’s. In 1974, the United States Consumer Products Safety Commission (“CPSC”) published an article which reported “problems of exploding filter tanks.” There are dozens of reported cases of these explosions. A company called B & S Plastics (doing business as “Waterway”) recalled almost 20,000 of its filters after receiving several sudden separation claims. Many pool filters that have similar problems are still in use today, a ticking time bomb in unsuspecting owners’ backyards.
