Backed by a 2-year warranty, it’s a smart upgrade for efficient, quiet, and reliable water pressure control.

## Description

Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot water delivery.DETAILSComposed of food grade plasticsReduces pump cyclingIncreases pump lifeReduces strain on plumblingReduces strain on batteryReduces noise of your water systemAllows for better control of hot waterSTANDARD CONFIGURATIONSInternal Volume: 0.75L/23.5OZPre-charge (PSI/BAR): 10/0.7Max Operating(GPM/LPM): 125/8.6Air Fill Vale: standard automotive style tire valveInlet/Outlet Dia: 1/2" MNPTWeight: 0.79 lbsDimensions: 14.37" x 7.87" x 4.92"
