Marylou Ward and her husband were sitting in their Port Charlotte home as a thunderstorm rolled through on Sunday when she said she heard a “boom” that was “the loudest noise I ever heard.”

“We smelled smoke and I looked outside,” Ward told WINK News. “It was the smoke from the septic tank that was coming.”

When she went into her bathroom, she found our that the toilet was now in bits of pieces. A plumber from A-1 Affordable Plumbing Inc. told the couple the lightning strike ignited methane gas that built up in the pipes and septic tanks. Methane is typically emitted during the breakdown of sewage in waste systems.

“The toilet exploded in homeowners master bathroom sending porcelain airborne like a missile (the porcelain penetrated into wall). Most likely all sewer piping will need to be replaced and septic tank,” a plumber posted to Facebook.

“Luckily no one was hurt! Scheduling a camera inspection this week to see how much sanitary pipe needs to be replaced!!”

Besides her toilet being destroyed, Ward said her septic tank and indoor plumbing were also wrecked. The blast also broke a window in the couple’s master bedroom and destroyed yard decorations. No one was hurt during the incident, but Ward said it made her feel lucky.

“I’m just glad none of us were on the toilet,” she told WINK News. “That’s the main thing.”

In 2018 the Sunshine State had the highest density of lightning strikes, according to environmental measurement specialist Vaisala released its Annual Lightning Report. Florida had the highest average of negative ground-to-cloud flasher per square mile, with 24, according to the study.

Lighting typically strikes tall objects such as trees and skyscrapers because their tops are closer to the base of the storm cloud, according to The National Severe Storms Laboratory.
