Watts Whole House System for increasing the pH of acidic water.
Series PWBWCAL acid neutralizing system are designed for
residential applications with intermittent flow rates up to 15 gal-
lons per minute. They stop the corrosion of metal components
and fixtures within a plumbing system by neutralizing the acidic
nature of supply water that has a pH of less than 7. Periodic
backwashing of the media bed cleans it of captured impurities.
Features and Benefits
• Increases the pH of acidic water
• Eliminates the corrosion of plumbing and fixtures caused by
low pH water
• No more “green stain” copper deposits in tubs, toilets, and
sinks
• Better tasting pH balanced water
• User-friendly equipment
• 10” diameter tanks and larger have a dome hole access port
on the top for checking and adding media
• Low maintenance due to automatic operation
Media
These systems use a high quality granular calcite (calcium car-
bonate) media to accomplish the neutralization process. As low
pH water flows down through the media bed it reacts with the
calcite media and dissolves it. This causes the pH of the water
to move from an acidic state to a neutral state. This dissolving
of the calcite media will require calcite to be added to the bed
over time.
Pro SE Series Control Valve
The Pro SE Series control valve has been engineered and
tested to withstand the equivalent of 27 years of uninterrupted
daily use. The proprietary design features a Teflon ® coated pis-
ton that glides through a series of seals and spacers. This seal/
spacer and piston configuration is the most reliable design in
control valve technology. The valve features an electronic con-
troller for easy programming.
Filter Tank
Features a fiberglass tank with a thermoplastic inner liner. The
tanks are NSF/ANSI Standard 44 or 61 certified.
Note: Do not use with water that is microbiologically unsafe or
of unknown quality without adequate disinfection before or after
the system.
