Where do I install it?

Aqua-Rex is simple to install. Just wrap the wires around the inlet to the water heater or on the softener loop and plug the transformer into an outlet. You don't need to cut any pipes or do any other kind of plumbing. Just check that the light is flashing and you can leave it to work all year long for about $20 in electricity. Just Fit it and Forget it!

Does it treat all the water in the home?

Aqua-Rex 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 units.

How does it compare with a water softener?

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.

Is it as good as a water softener?

Aqua-Rex can partially soften hot water, it reduces scaling and also gets rid of old scale in the home. You can use less soap and detergents and there is no slippery feel to the water. It is nearly as good as a water softener!

Will it work on any pipe?

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

Which unit do I need?

The WK1 and the WK1-E will fit on any pipe size up to 1" and can also be fitted on a 1¼" softener loop. It doesn't make any difference how big the house is or how much water is used. If you have an electric water heater, and especially if you are on well water, we recommend the WK1-E.

Will it do what I want?

Only you can decide that. Try it and see! We give you a no condition money back guarantee so you have nothing to lose except your limescale!

What else can Aqua-Rex do?

Swimming Pools:- Aqua-Rex is great for clearing the scale from around the water line. It helps keep the filter and heater scale free and helps biocides act on bacteria so the pool is cleaner and clearer. It reduces phosphates so it is especially good for salt water pools. The WK1P is fully waterproof and will fit on 2" plastic lines.

Does Aqua-Rex work on the Dishwasher?

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 Lemishine 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.

Can Aqua-Rex treat anything bigger than a home?

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.



"Since the installation of AQUA-REX in my home, I have enjoyed the following: noticeably softer skin; reduced redness in my eyes after showering; improved efficiency of hair and skin products (I need less to achieve same results); diminished severity of eczema. After experiencing these positive results with my system, I purchased a unit as a gift for my mother! Now she is also benefiting from the AQUA-REX system."
