Jabsco 30573-0000 Marine Pressurized Water Accumulator Tank with Bladder (1-Liter) , Black

The media could not be loaded. I installed a new FloJet pump on the sailboat and the water pulsing was so bad that it would splash out of the galley sink! I tried to research if a small accumulator tank would “solve” the problem or just “help” a little. Decided to go with this model as it is 1 liter instead of the 3/4 liter of other brands. The flow now is silky smooth!!! Check the video…problem SOLVED! I couldn’t be happier with this purchase!

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

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.

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.

I purchased this to replace the same model that was already installed on my boat. Installation was simple as I already had the fittings from the existing unit. The fittings push into each side and are then locked in place with some sliding wedges. The whole changeout process took less than 5 minutes. In the case of a new installation, you need to find a location where you can mount the housing, and cut into existing lines. This particular unit shipped with one straight and one 90 degree hose barb fitting, while the old unit had straight hose barb fittings on both ends. Since my hoses were already lined up, I reused the existing fittings. Unit works well, greatly reducing the pump cycling.

Just past the warranty. Will no longer hold pressure.

Wow! What a difference. Installed in place of existing 2.5 gallon pressure tank. Excellent decision. My pump runs less. I have two heads one galley and a transom shower. I don’t think it would keep up with all open but two of them it could. Great space saver too!Ok, it's a year and a half later and the internal bladder has ruptured and it doesn't hold pressure. I've had to continue to recharge the precharge every 6 months (to the prescribed 10psi). Now, I need a replacement. Your call from here.

Direct replacement for a previous accumulator, thought I'd get away with reusing my existing quick-connect fittings. A 5-minute replacement turned into an hour of little drips, until I installed the (same?) supplied fittings that came with the accumulator. Once I used the new supplied fittings, everything worked great.I've now lost 3 of these accumulators over the years, which is a little crazy. Clearing the lines out with pressurized air to winterize the boat never gets rid of 100% of the water, so it freezes over winter and cracks. I pump pink-antifreeze through the lines to take care of any trapped water, but then I think the internal bladder wears out from the alcohol. It's a no-win with this accumulator :(
