Review: Water system runs much more smoothly. - I was really gratified at the huge improvement this little one liter accumulator made for my marine potable water system, no more cutting in an out or stuttering when I wash my hands or a dish. Increasing the pre charge was easy with a bicycle pump and gage. Manual says to set 3 psi below cut in pressure, a label on the box says 2; I used 3 but I doubt that matters much. I was worried about the o ring seal and retaining clips, but it hasn't leaked a drop all summer.
Review: Works, but expect failure - Smoothed out the water pump on my boat system, but I do not expect it to last. This stores pressure in an internal bladder filled with air, so the minor uses do not cycle the water pump. The bladder is slightly pressurized with a standard bicycle pump. The last rubber bladder failed, so I expect this one to as well in a couple years. Unfortunately, even though I could easily replace the rubber bladder, it is not sold, so it is a $100 replacement. The other problem is there is no guidance for what to pressurize it to.

### ⭐⭐⭐⭐⭐ great but, note on clips
*by J***F on March 9, 2025*

all good. Note that they changed the clips from the old models, use the new ones or it will leak.
