What Is an RV Accumulator Tank?

    An RV accumulator tank helps the water pump. These small gadgets enhance the performance of the water pump by reducing the water cycle, saving battery power, and preventing water pressure increases that could damage your RV. Without an accumulator tank an RV water pump cycles on and off to maintain pressure in the water lines. This cycling can cause pulsing in the water flow and uneven flow. You can install it anywhere on the pressurized side of the water pump.

Almost all homes with well water use an accumulator or pressure tank for the same reason, so why not in an RV?

An accumulator tank uses a small air bladder inside the tank that is like a balloon. You inflate this “balloon” to a certain pressure and when the pump kicks on it compresses it. With the pump off the pressure in the balloon can continue to push water out of the tank and into your water lines.

SINGFLO 0.75L Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot water delivery.
