Reverse Osmosis Storage Tanks

All reverse osmosis storage tanks supplied with Purestream Undersink Water Filter units are steel-made with precision weld seams to ensure superior structural integrity, coupled with a virgin polypropylene liner to ensure that all areas in contact with water are made to be NSF58 and CE approved.

Tanks are pressurised to 5-7 psi and contain a quality, virgin sourced, food grade Chlorobutyl diaphragm which pushes the water through the tank as the tap is turned on. A pressure valve is situated towards the base of the unit and covered with a blue sleeve, and can be adjusted using a bike pump if pressure drops below 5 psi.
