A system and method for measuring liquid levels in a plurality of recreational vehicle holding tanks uses an electric air pump and a selection unit to measure the air pressure required to selectively pump air to the bottom of the holding tanks. The electric air pump is actuated using a user-operated electrical switch and is shut off by a normally-closed pressure switch when the air pressure at the outlet of the electric air pump exceeds a threshold. The liquid level in each tank can be measured using a pressure gage that reads the air pressure downstream of the electric air pump, which equals the pressure of the liquid at the bottom of each tank.
