Jetted cleaning of RV black and gray tanks

What it is

• Jetted cleaning uses high-pressure water delivered through a specialized nozzle to remove built-up waste, biofilm, mineral scale, and odors from the interior walls and plumbing of black (toilet) and gray (sink/shower) tanks.

• The nozzle spins or sprays at multiple angles to reach seams, baffles, and trap areas that ordinary flushing can’t clean.

Why it matters

• Removes stubborn deposits and solids that cause clogs, slow draining, and strong odors.

• Breaks down biofilm and mineral buildup that can protect bacteria and retain smells even after dumping.

• Helps restore proper tank capacity and improves sensor accuracy (full/empty readings).

• Reduces need for harsh chemicals, extended dumping, or tank replacement.

Typical jetted cleaning process

1. Inspection: Technician checks tank access, valves, fittings, sensors, and any visible damage. Tank is partially emptied if needed.

2. Access setup: Service connects to the tank through a cleanout port, toilet flange, or exterior access panel.

3. High-pressure jetted rinse: A rotating or multi-nozzle jetted head is inserted into the tank. Water pressure and nozzle
