Aqua-Rex Frequently Asked Questions

Aqua-Rex is the only device of its type with US independent third-party performance verification. When tested by IAPMO R&T Labs it showed it could reduce scaling by 83% in Las Vegas water heated to 180°F for 23 hours.

Aqua-Rex is simple to install. Just wrap the wires around the inlet pipe to the water heater. Second choice would be on the softener loop or third choice anywhere else on the cold-water supply. Remember the signal goes in both directions, upstream and downstream so you don’t need to pass the water through the wires to have it treated. Just plug the transformer into an outlet – that is all you have to do. No set up or calibrating and it needs no servicing, supplies or maintenance, it is Plug and Play. It cost around $20 a year in electricity. There are no pipes to cut or plumbing to play with so it’s perfect if you are a Renter. Just remember to take it with you when you move home.

Aqua-Rex treats all the water in the home, all the time. It sends a signal into the water heater even when no water is flowing, and it also sends a signal back into the cold supply in the rest of the home so mixing valves, showerheads and kitchen faucets won’t get scaled up either. It is OK to treat the water to the kitchen faucet because it doesn’t add unhealthy sodium to the water, instead it retains the healthy calcium.

Aqua-Rex doesn’t use any salt or chemicals and it doesn’t produce any environmentally unfriendly discharges. It needs no maintenance or servicing and it costs hardly anything to run. It doesn’t add any unpleasant taste to the water or risk any additional corrosion to your plumbing system. It’s a lot less expensive to buy, install and maintain.

Aqua-Rex reduces scaling like a softener, but it also gets rid of the old scale in the home which a softener won’t do. It partially softens hot water, so you use less soap and detergents, but you don’t get that slippery feel to the water from the sodium dumped in by a softener. It can deliver about the same benefits as a conventional water softener, and there’s no salt to haul!

You can wrap the Aqua-Rex wires on any type of pipe material: plastic or metal, even the flexible copper inlet pipe to the water heater.

Aqua-Rex is great for clearing the calcium scale from tiles and water features. It stops scaling in the saltwater chlorine generator and makes the biocide work more efficiently. It reduces phosphates thus making the pool clearer. The WK1P is fully waterproof and should be installed on the circulating line after the pump. Ask for Aqua-Rex in your local pool store or see the equivalent Jacuzzi de-scaler in your local Leslie’s Pool Supplies.

The answer is no! The pump in the dishwasher reduces the effectiveness of Aqua-Rex so you need to use a good hard water detergent and most importantly a hard water rinse aid, such as Lemi Shine ®, which is available from most stores. If you follow these instructions you should be happy with the results from the dishwasher. Laundry washing machines work better with Aqua-Rex.

Aqua-Rex units are available for all pipe sizes and are installed on hotels, condos, industrial plants and cooling towers. They are used in schools, colleges and military bases, everywhere that hard water is a problem.
