Introduction

The Watts OneFlow® system provides protection from scale formation throughout the plumbing system. The OneFlow system can be installed at the point of entry to treat your entire system, both hot and cold water, or it can be located directly before a water heater or other device (e.g. steamer, etc) that requires protection from hard water.

OneFlow and external plumbing surfaces as well as reducing spotting and streaking normally associated with hard water.

OneFlow solved hardness minerals into undissolved crystal micro-particles. These crystals stay suspended in the water and have a greatly reduced ability to react and attach to surfaces like dissolved hardness does. Therefore, the problem of internal buildup of scale in pipes, water heaters and on ﬁxtures and glass is greatly reduced.

Using OneFlow® with other water treatment equipment.

Due to the unique properties of OneFlow®, there are some unique requirements for using OneFlow tion or other forms of water treatment.

1. OneFlow not install any ﬁlters after OneFlow which scale prevention is required. POU drinking water ﬁlters, e.g. carbon or RO are exempt from this requirement.

2. Do not apply phosphate or any other antiscalant either before or after OneFlow

Important note about iron, manganese and copper

in the water supply

Iron and Manganese

Just as with conventional water softening media, OneFlow® needs to be protected from excess levels of certain metals that can easily coat the active surface, reducing its effectiveness over time. Public water supplies rarely, if ever, present a problem. However, if the water supply is from a private well, conﬁrm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L and 0.05 mg/L respectively. Copper should be less than 1.3 mg/L.

Cautions!

• Do not let the system freeze. Damage to the tank may result.

• System must be operated in a vertical position. Do not lay it down during operation. The system may be placed in any position for shipping and installation but must be operated in the vertical position.

• Place the system on a smooth, level surface. Because the system operates in an UP-Flow, fluidized bed mode, having a level surface is more important than with a softener or media filter.

• A bypass valve should be installed on every system to facilitate installation and service.

• Observe all local plumbing and building codes when installing the system.

Copper

Copper usually originates from new copper plumbing upstream of the OneFlow waiting 3-4 weeks before placing the system in operation. This will allow the copper surfaces to be fully ﬂushed and develop a natural protective surface. To further minimize any problem with excess copper, avoid applying excess ﬂux on the inner surfaces of the pipe and use a low-corrosivity water soluble ﬂux listed under the ASTM B813 standard. Once the plumbing connections are complete, place the OneFlow lowing the startup procedure and ﬂush the plumbing for at least 10 minutes.

Notes to the Installer

The OneFlow® system differs from a conventional softener or media ﬁlter in a number of key respects.

• The system is light and only partially filled with media. This is normal. The UP-flow operation of the system requires a lot of freeboard to allow the bed to fully fluidize.

• The system has no underbed so you can tip the system over without any fear of upsetting the media. This makes transportation and installation much easier than conventional systems.

• Because the OneFlow the tank connections are opposite of traditional installations.

Note to the building owner

Your OneFlow® system will improve the properties of water throughout your building. Here are some things to expect and some recommendations for maximizing the beneﬁts and your enjoyment of OneFlow

Dishwasher-Spotting on dishes and on the surface of the dishwasher should be greatly reduced or eliminated. We

recommend that you immediately reduce the amount of dishwashing detergent by approximately 50% as compared to hard water use. Dishwashing detergents low in phosphates are highly recommended as they are better for the environment and phosphates can cause spotting. In very hard water areas, the use of a rinse aid may be advised.

Shower doors and tiles- should have little or no spotting. When water evaporates off a surface, small spots may be left behind. These spots should 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.

Sinks and ﬁxtures - should have little or no spotting. If water is allowed to evaporate off a surface, small spots may be left behind. This spotting should not require any more than a wet cloth or sponge to remove. No harsh chemical should be required as with typical hard water spotting.

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 because 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 initial cleaning OneFlow

We also recommend that you drain your water heater tank. This should be done 30 to 60 days after OneFlow again in one year. This is a good practice that can dramatically increase the life of your water heating appliance. The OneFlow help keep the tank and heating elements free of scale and operating at peak efﬁciency. Please follow the manufacturers instructions when draining the tank!
