A compact, no-power-required hand pump that connects directly to Pro-Fill RV, Qwik-Fill, and Millennium SPW onboard battery watering systems. Fill every cell in seconds using only distilled water and a steady squeeze -- no bending, no spills, no guesswork.
The Flow-Rite RV-2020 is the hand-operated companion pump for Flow-Rite onboard battery watering systems. If you have a Pro-Fill RV Edition, Qwik-Fill, or Millennium SPW single-point watering system already installed on your coach or vehicle, this pump gives you a clean, quick way to top off every cell without tools, electricity, or a pressurized water source.
Just connect the quick disconnect fitting to your watering system's port, place the intake tube into your container of distilled water, and squeeze. The dual check-valve bulb moves water in one direction only -- into the battery -- preventing backflow and keeping things tidy. The included intake filter keeps debris out of your cells.
Dual check valves ensure water flows in one direction only. No backflow, no mess during use.
Snaps onto Flow-Rite Pro-Fill RV, Qwik-Fill, and Millennium SPW system ports for a leak-free connection.
Filters debris from the distilled water source before it reaches battery cells, protecting cell internals.
Fully manual operation -- no 12V outlet, shore power, or battery charge needed to use this pump.
The RV-2020 is designed for use with Flow-Rite's onboard single-point battery watering systems. Compatible systems include:
This pump is the manual alternative to Flow-Rite's 12V electric pump option. If you prefer not to run power to your watering system port, or if you water batteries infrequently, the RV-2020 is the practical choice.
The RV-2020 is well suited for:
Always fill flooded lead-acid batteries with distilled water. Tap water contains minerals and chlorine that contaminate electrolyte and shorten battery life. This pump is a transfer tool -- it does not filter or purify water.
