RainPac rainwater bladder tank harvesting systems are the perfect solution for rainwater storage. Using, in many instances, otherwise unused space under houses, buildings, and decks, RainPac flexible rainwater tanks allow vast amounts of soft rainwater to be stored without ruining the aesthetics of your home, nor taking up yard space.  By using these areas, RainPac does not sacrifice space and house aesthetic for valuable water storage.

Behind every great brand is an even better warranty!  Every RainPac is covered by FloatPac’s 10 year manufacturer’s warranty.  This is further back by FloatPac’s successful 35 year manufacturing history, and a combined public and product liability insurance of $20 MILLION dollars!  This is an excellent back up for your family and household just in case (highly unlikely) something goes wrong with your RainPac bladder system.

RainPac – because it never rains forever.

Standard sizes:

We also offer a complete custom made to order service so that we can tailor make a RainPac pillow tank to suit your exact measurements.  For a no obligation, free of charge quotation, please contact us and advise your length, width and height available, and our sales team will provide you with a quotation.
