We find hidden leaks before opening walls or floors.

Hydro Jetting
Right now: Repeat clogs usually mean buildup or roots in the line. A camera inspection shows the cause before you spend on a fix.

Tankless Water Heaters

What's the difference between snaking and hydro jetting?
Snaking (cabling) pushes a rotating cable through the clog to open a path, which works well for simple blockages. Hydro jetting uses high-pressure water to scour the whole pipe wall, removing grease, scale and roots, so it's the better fix for recurring clogs. Many jobs start with a camera to decide which one the line needs.
Do you install tankless water heaters?
Yes. Flash Plumbing Inc. installs Navien tankless water heaters, including tank-to-tankless conversions with any gas line and venting upgrades the switch needs.
