Pre-Pressurized Accumulator Tank

I installed the pump on old loran shocks and the acumulator, today you can not hear the pump unless you are right next to the bathroom sink and then it only hums, the acumulator helps with having a constant flow of water with no pulsing.

Before the instal the pump sounded and felt like a jack hammer was beimg used in the RV.

I installed a Sureflow tank, I think it was a two gallon unit which allows about a gallon to run before the pump kicks on. If you install one, also install the quieting kit. It helps to cut down some of the noise and makes the installation easier. I believe the instructions tell you to check the air pressure in the tank before you install it. I can't be more specific because the MH is a long ways away right now. I believe the cost and installation time was worth it.

The total pump run time to pump a given amount of water is still the same, however the volume of water that the accumulator contains can be used before the pump will be energized. Once it does come on it will run long enough to satisfy the demand plus whatever is needed to recharge the accumulator.

Considering installing a Shurflo 182-200 Pre Pressurized Accumulator Tank and I need to better understand how they work.
I know they will reduce the run time on the pump and eliminate the constant on/off/on of the pump that seems to occur all too ofter but just how does it do it?

Did you go to the Shurflo website?

Not sure what you mean by "how often it does it". Does what? It's activity depends on how long you run the water. It is just a small tank with a bladder diaphragm mid length with air on one side and water on the other. As the pressure drops on the water side the bladder equalizes the pressure up to a certain point and then beyond that the pump kicks in. In other words it fools the pump into thinking there is no pressure drop if only a little water is used and the pump does not come on. When it does it pressurizes the water side again and the cycle repeats itself until you shut the flow off.

It works and is a good and inexpensive modification which I automatically do when I get an RV.
