RO Storage Tank
Within 24 hours of placing the order I received the RO Storage Tank. It was simple to install. It took me about ten minutes to remove the old one and put the new one in. I would definitely order from ISopure water again.

Ordered the tank from your website and received it very fast in perfect condition. I would do business with you again if I need anything for my RO.
