Review: Good quality and reasonable price. - Quick delivery and very good quality, works great!
Review: Perfect replacement/upgrade for Jabsco 12573-2000 - I wish you could give bonus stars! The old jabsco 12573-2000 accumulator sprung a leak and I don’t think they make that model anymore and I REALLY didn't want to change styles, sizes, or drill new holes. I found this for an absolute bargain compared to the closest jabsco replacement and hoped it would work as it looked identical in size and shape from the picture to the old one. Not only was it physically the same size but even the screw holes lined up exactly the same. The fact that it even has rubber isolators in those screw holes was icing on the cake. The fittings are the easy to use plastic hand screw wingnut style and are extra long. I was concerned about the length difference but when I went to take the old accumulator out, the hoses were stuck. No problem! With the longer fittings I simply cut the hoses off at the old fittings and popped them right on the new ones. It’s like the person that designed this had actually done the job before. If you’ve done any work on a boat, you can greatly appreciate all of those details that make the job that much easier. The standard valve stem and bladder system are an upgrade over the old one as well. All in, it took me longer to gather and lay out all of the tools I was expecting to have to use than to actually replace this part. I want to say it was maybe 10 minutes. If you are in the same boat as I was, do yourself a favor and buy this!

### ⭐⭐⭐⭐⭐ well made accumulator tank for your RV
*by E***3 on February 1, 2025*

I bought this accumulator to try and stop the pulsations of the water pump in my RV. They have smaller versions of this that are about a quart in size. I chose to go with the 2 gallon one. it is obviously larger and takes a little more room in a cabinet but so worth it. Installation was not to difficult, except for working in a cabinet. You will need to buy some pipe fittings to install it also. it worked so good, no more pulsations in the water, just like home. They pump does run longer when the pressure in the tank drops to the cut in point however it does not run as often and turn off and on rapidly with lower water flows. I highly recommend one of these for your RV
