Note To The Home Owner

Your OneFlow

®

 system will improve the properties of water 

throughout your home. Here are some things to expect and 

some recommendations for maximizing the benefits and your 

enjoyment of OneFlow

®

Sinks and fixtures -

 should 

have reduced spotting.  If water 

is allowed to evaporate off a 

surface, small spots may be left 

behind.  Many times this residue 

is easier to clean up than the 

previous hard water spotting.

Dishwasher-Spotting on 

dishes and on the surface of 

the dishwasher should be greatly reduced.

  We recommend 

that you immediately reduce the 

amount of dishwashing deter-

gent by approximately 50% as 

compared to hard water use.  

Dishwashing detergents low in 

phosphates are highly recom-

mended as they are better for 

the environment and phos-

phates can cause spotting.  In 

very hard water areas, the use of a 

rinse aid may be advised.

Shower doors and tiles-

 should 

have reduced spotting. When water 

evaporates off a surface, small spots 

may be left behind. Depending on 

water chemistry, these spots may be 

easy to remove with a damp 

cloth or sponge.

In the bath

 you should notice 

that soaps and shampoos 

lather more than with un-

treated water.  Soaps and 

shampoos will also rinse off 

much easier and faster than 

they would with traditional soft 

water. We recommend the 

use of modern soaps for the 

best results.

 Media 

Replacement

The Watts OneFlow

®

 media has an average life span in ex-

cess of 3 years depending on water volume and specific water 

chemistry. If you notice a change in performance after a three 

year period and feel the media should be replaced contact your 

system installer, professional plumber, or water treatment expert 

to perform a re-bed service. The color of the media should be 

noted any time it is replaced to ensure the media has not be-

come fouled. If it has, additional pretreatment for the system may 

be necessary.

Replacement Media

OFRES-0835RM Media should be replaced every 3 years
OFRES-0935RM Media should be replaced every 3 years
OFRES-1035RM Media should be replaced every 3 years

Things to watch for:

During the first 30-90 days:
• Faucet aerators and drains may plug occasionally as old scale 

is removed from your plumbing system and water heater.  
• You may also see milky water while the descaling is taking 

place. This is simply an increase in the calcium in the water be-

cause OneFlow

®

 is removing old scale deposits from your pipes.

Good practices:

If your dishwasher is severely coated with scale at the time of 

installation, we recommend that you purchase a product like Jet-

Dry

®

 Dishwasher cleaner to accelerate the cleaning.  After this 

initial cleaning OneFlow

®

 should keep it clean.

We also recommend that you drain your water heater tank. This 

should be done 30 to 60 days after OneFlow

®

 is installed, and 

again in one year. This is a good practice that can dramatically 

increase the life of your water heating appliance. The OneFlow

®

will help keep the tank and heating elements free of scale and 

operating at peak efficiency. Please follow the manufacturer's 

instructions when draining the tank!
