Gas Ballast Knob
Gas Ballast Knob
The RV series pumps are the industry standard. Over 400,000 units have been sold. They are tough and reliable. The gas ballast is a key feature on these pumps. It lets you pump water vapor without ruining the oil.
But the gas ballast knob gets used a lot. It is exposed to the environment. It can get bumped. It can get broken.
