Installing water accumulator in my 2023 Airstream 27FB. Love how it helps with less pump pulsating, quieter water pump and helps with pump longevity. It also helped with more consistent hot water with my on-demand hot water system when I turn the water off and on in the shower.

- Disconnect line out hose on water pump, connect new hose to water pump.
