## Description

Finerfilters AquaPro Reverse Osmosis 11 litre Pressurised Storage Tank Replacement pressurised water storage tank for your Reverse Osmosis Water filter system. This tank can be connected to additional tanks to increase the storage capacity on your Reverse Osmosis system. This tank is an air bladder tank meaning the water does not touch the metal outer shell, but rests in a butyl bladder. There is a small air charge between the outside of the bladder and the inside of the tank. It’s the air pressure that pushes the water out of the tank when the tap is opened. The tank is pre-charged with air but will require topping up as part of the regular maintenance of your reverse osmosis system. Air can be added using a bicycle pump or similar. Tank uses ¼” valves. Stainless steel, 3 gallons (11.35 litres). Operating pressure 6 bar (80-90 psi) Weight is 3.4kg including the box. Dimensions: 280 x 280 x 375 Please Note: All tanks are sold without a tank valve. If you're replacing an existing tank, your old tank valve will probably work. If you want a new valve, please contact us before placing your order

Review: Does what it says on the tin. - I am happy with this purchase which replaced my old tank. Now I have the water pressure to restore my RO system. Which many pros wanted to replace at four times the cost. Good value.
Review: Disappointed - Just received my order today and it was damaged as you can see by the photo, and it would cost me to much to send it back. 😭
