RV/MARINE APPLICATIONS The most efficient use of the accumulator occurs with the pre-charge set at the SAME pressure as the pump’s pressure switch “turn on” setting. Typically, a 40 psi [2.7 bar] pump will turn on at 20 psi [1.4 bar]. Therefore, the pre-charge should also be 20 psi [1.4 bar].
Do I need an accumulator tank in my RV?
An RV accumulator tank helps the water pump. 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.
What does accumulator tank do?
The Accumulator Tank smooths water flow and reduces on/off cycling of the pump by lessening the variation in pressure and flow between the pump and the outlets in the system. The even flow of water gives better control of hot water temperature especially noticeable with instantaneous gas water heaters and with showers.
Is an expansion tank the same as an accumulator?
There is a difference. An accumulator tank will have an air bladder and will store the water under pressure. An expansion tank is just an empty vessel that holds water. You want an accumulator tank for your RV.
How should an expansion tank be installed?
An expansion tank is generally installed directly above the water heater by means of a tee-fitting installed in the cold water delivery pipe. The expansion tank is usually installed horizontally, though it is acceptable to install it vertically if it is necessary because of space limitations.

How do you size an accumulator?
Suppose you calculated that 230 cubic inches will be needed for your application. The minimum accumulator capacity is: 230 ÷ 55 = 4.18 gallons. The nearest standard accumulator size is 5 gallons – the correct size to use.
Where is the most common place to install an expansion tank?
Your expansion tank can be anywhere on your plumbing system and does not need to be installed in close proximity to the water heater. It is most commonly installed using a “T” at the cold inlet to the water heater. But, functionally, it can be installed anywhere on the cold inlet line.
Where should an expansion tank be located?
The expansion tank (potable water type) should be installed on the inlet cold-water line. It can be installed anywhere in the building on the cold-water supply (after the regulator). It is usually installed by plumbers on the cold-water inlet of the water heater.
Does Pentair own shurflo?
In July 2004, Pentair bought WICOR Industries, the former water systems subsidiary of Wisconsin Energy, for $850 million. WICOR made water pumps, filters, and pool equipment components under the Sta-Rite, SHURflo, and Hypro brands.
