## Description

A genuine Jabsco part

Review: Great service - Arrived in four days. desertcart under-promise and over-deliver. Excellent service. As for the accumulator, I bought to replace a 9 year old unit - the old one had developed a small approx 4mm crack in the membrane (bladder). It's a pity it isn't possible to buy just the membrane. The unit is very simple - three main parts. The lower half has the hose connections. The upper has the air valve. Both halves bolt together with a rubber membrane/diaphragm/bladder in between which also doubles as a seal between the halves. It's a waste that I can't simply replace the faulty membrane. Despite not being able to save the planet this time, great service from desertcart. I should add that I live in the UAE and am not accustomed to such short delivery times.
Review: Fitting an accumulater . - The accumulator has now been fitted and has cut down the stop start of the freshwater pump considerably .

### ⭐⭐⭐⭐ Bien, mais mode d'emploi incomplet.
*by F***H on 18 April 2024*

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. :-(
