FAQ's

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

 

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 its 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. Its 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 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.

If you have a gas water heater supplied by city water you need the WK1. If you have an electric heater, or if you are on a well water supply with a gas heater, you need the WK1-E. Both fit any line size up to 1″ and it makes no difference how large the home is or how much water is used.

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!

Swimming Pools:- Aqua-Rex is great for clearing the calcium scale from tiles and water features. It stops scaling in the salt water 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.

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.

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 I installed the WK1 on 6/25/2009, I used the WK1 for build up on the aerators on the faucets, shower heads and glass shower walls which were terrible! After the WK1 was in use for 7 months the build up has almost totally disappeared without any physical cleaning.

I also have a tankless water heater that needs to be de-scaled once a year, to keep the performance ` the way it should be. After the first year with no WK1 installed, the first cleaning with a de-scaling product, the solution begins somewhat clear and light blue in color at the beginning, and after the 45 min flushing time the solution came out a rusty dark color with lots of scale. After the second cleaning with the WK1 installed for 8 months, the same solution used for 45min flushing time came out virtually the same as when it started, clean and clear.

I have recommended your product to friends and associates.

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.

I had the Aqua Rex system installed in my home for almost a year now and it is doing everything I was told it would do. First of all the system is easy to install and does not require any special tools and the Aqua-Rex system does not use a lot of energy. My scale build up on faucets and shower heads has been eliminated as a result of the Aqua-Rex system

Jonny, wanted to take a moment and thank you for introducing Aqua-Rex to me at the PWQA meeting in Anaheim several years ago. 2008 I believe. We install a lot of Rinnai, Eternal and Takagi tankless water heaters and recommend your product on every installation for scale prevention. When the client hears that they will not have to do the maintenance on the heater as often, it is a no brainer sale. In today's world, people are not wanting the hassle of a salt based water softener and Aqua Rex is a great alternative. We have installed 47 of the WK1 units and only had 1 customer not like the product. I would say that is a pretty good success rate. Any way's just wanted to drop you a line and say thanks.

Jonny, Thank you for taking the time to discuss the Aqua Rex with me yesterday at Pacific Plumbing in Wasilla. I'll research my customer data base this week and next for info on how the customers like having the WK1-E. I do have a customer that has one in her house and brochures in her beauty salon. She yells from the mountain tops how she likes the Aqua-Rex. She could tell a difference in just one week how her shower sprayer and kitchen sink sprayer where now working better and more outlets where unclogging (16 GPG). I also had a customer tell me that after just 2 days she could tell a difference in the her water, by having to use less soap (19 GPG). She said the water felt as if a Softener had been installed like it was in her previous home.

Thank you again for you time and the new article.
