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

The accumulator has now been fitted and has cut down the stop start of the freshwater pump considerably .

This is a great bit of kit, evening out water flow, essentila for an instantaneous water heater. However, I feel that it is seriously over priced being just a bit of plastic and rubber. It can't cost a lot to make. Also, spare bladders/diaphragms are not available, if there is a split in the diaphragm you have to buy a whole new unit. My first one lasted at least 10 years and I will buy anotherwhen this one fails.

Le compresseur fait très bien son travail; mais ce n'est que par hasard, après plusieurs semaines, que je suis arrivé à le faire travailler comme je le souhaitais : le taux de compression maximal de l'air est bien indiqué, mais pas celui de fonctionnement conseillé; et ils sont très différents. :-(

Perfect replacement, fit into the same location, even the same screw holes.

It is relatively small and very easy to install. Functions as advertised at lest so far into a months use.

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.

The tank arrived quickly and was completely as advertised. Easy to install as well.
