St. Petersburg Water Leak on Floor: Tracking the Source Without the Guesswork

When a homeowner in St. Petersburg saw water collecting on their bathroom floor, they did what most people would do — grabbed a few towels and hoped for the best. But after the second day of soggy floors and no visible source, they realized this wasn’t going to solve itself.

They called I Find Leaks — and Jeremy, known as “The Leak Whisperer,” headed straight to the home.

When Jeremy arrived, he found standing water on the bathroom floor with soaked towels between the shower and vanity.

Right away, Jeremy spotted two soaked towels stuffed between the vanity and shower. There was no visible water flowing from anywhere obvious, but the fact that the towels were completely saturated told us something was active. That’s when we got to work.

Using advanced thermal imaging tools, Jeremy began scanning the floor around the toilet. Our infrared technology lets us see changes in temperature that often reveal hidden moisture. In small bathrooms like this, where multiple plumbing fixtures are close together, guessing isn’t an option — you need precise tools and experience.

After confirming that nothing was actively leaking near the toilet base or vanity, Jeremy turned his attention to the shower wall. The floor just outside the shower was damp, and the heat signature suggested that something was wicking behind the drywall.

We never cut until we’re sure. But in this case, the thermal scan led us to one specific location behind the wall. Jeremy made a single, clean 3-inch by 4-inch cut into the drywall — the only hole made during the entire job.

Behind that small access hole? Exactly what the thermal camera predicted: pipe fittings feeding the shower valve, right above the area where the floor was damp.

Right behind the cut drywall, Jeremy finds multiple pipe fittings — exactly where the leak was pinpointed.

A closer inspection confirmed it — a CPVC reducer fitting was weeping slowly into the wall, sending water down the backside of the drywall and pooling onto the floor behind the shower and vanity. This is why guessing doesn’t work. Without the tools and training, you’d never find this leak until the damage had gotten much worse.
