How to Use Soft Water
Now that your Sumo water system is installed, you can enjoy all the
benefits of having soft water. If you are not accustomed to soft water,
here are some tips to follow to get the most benefit from your new
system:
Use pure soap products.
Most leading brands of laundry soaps,
household cleaners and shampoos contain large
amounts of detergents. The harsh chemicals in
these detergents are necessary when using
hard water, but you can reduce your use or
eliminate them altogether with soft water. We
recommend you use pure soap products, clear
liquid soaps without dyes and perfumes. If you
continue to use your normal detergents, you
should significantly reduce the amount used.
Your Monument Water Systems representative
can provide you with more information and
recommended detergent amounts.
Use less soap and household cleaners.
When using soap or cleaners with soft water, start by cutting the
amount of soap you normally use in half. You may even find you can use
as little as one-quarter the amount you were using before. Hardness
minerals in water interfere with soap’s cleaning ability. Once they are
removed, soap can do its job better. Even though you’ll use less soap,
you’ll get more suds and cleaner results.
It’s especially important to reduce the amount of laundry soap you use.
Washing clothes in soft water not only means
you’ll need less soap to get your clothes clean,
but also that the soap you do use will rinse out
completely. Washing in soft water makes your
clothes look whiter and brighter, and they’ll
last
longer too. It is very important not to let
your clothes sit in the washer after the cycle is
complete. Detergent buildup can stain your
clothing. When possible, use clear, liquid soaps,
without dyes or perfumes.
After bathing in soft water, your skin should
feel “slippery.” It’s not soap you feel on your skin. What you’re feeling is
your own smooth skin without any leftover soap curd or residue. When
you bathed in hard water, you were never able to rinse this residue off
completely. The soap curd that left a ring in your bathtub was also left
on your skin. But now that you have soft water, you’ll feel soft, smooth
and clean. The same holds true for rinsing shampoo out of your hair.

Reduce or eliminate the use of fabric softeners.
Fabrics washed in hard water retain soap curd or residue making them
“crackle” when removed from the dryer or stiff if air-dried. Fabric
softeners are necessary with hard water to keep your clothing soft, but
with soft water, you can reduce your use of fabric softeners or eliminate
them altogether.
Take special precautions with automatic dishwashers.
Soft water, when combined with caustic phosphates in some
dishwasher detergents and very high temperatures in the dry cycle, can
etch dishes and glassware. To prevent this possibility:
•use the “no heat” dry cycle on your
dishwasher;
•use the minimum amount of a good
quality, low phosphate dishwasher
detergent needed to clean your dishes.
This may be as little as 20 percent of
the amount recommended by the
appliance manufacturer or on the
dishwasher soap box;
•wash good china and crystal by hand.
Special care for plants and fish.
Depending on your water hardness level, amount of rainfall and how
often you water, you could use soft water for
outside watering, but why waste your soft
water? Water your lawn, shrubs and outside
plants from an outside hard water faucet, or
put your Sumo water system in by-pass
before watering. See “By-pass” on page 8 for
instructions on by-passing your system. Many
houseplants can be watered with soft water,
although some can be highly sensitive to the
elevated level of sodium ions in soft water.
You may prefer to water houseplants with
hard water or water from a reverse osmosis system.
Fish accustomed to hard water may have trouble with an abrupt change
to soft water. Make the change gradually over a period of seven to 14
days by blending hard and soft water until the tank contains 100
percent soft water. Once you begin using soft water, you should notice
that your fish tank stays cleaner longer.

Product Line Overview
The Sumo Water Softener is available in two (2) tank sizes that allow
you to use the ideal configuration for your application.
System Operation
Your Sumo Water Softener is designed to provide years of trouble-free
operation. The following cycles soften your water and regenerate your
system when necessary.
Service: Hard water enters the unit at the valve inlet and flows down
through the center tube. The hard water then passes through the lower
distributor and flows up through the resin. Conditioned water finally
passes through the upper distributor and flows to the system outlet and
into your home.
Regeneration:
Brine/Slow Rinse: Hard water enters the unit at the valve inlet and
flows into the compartment housing the venturi which draws brine
(or sodium chloride solution) from the brine tank or cabinet. Brine
flows down through the resin and then enters the center tube
through the lower distributor. Then, the brine flows through the
drain valve to the drain line. The resin beads are replenished with
sodium ions from the brine solution during the brine/slow rinse
stage. Since the resin beads prefer calcium and magnesium ions, an

overwhelming concentration of sodium ions during the brine and
slow rinse stages is necessary to force the calcium and magnesium
off the resin beads.
Backwash: Hard water enters the unit at the valve inlet, flows down
through the resin bed, and then through the lower distributor to the
center tube. The backwash water then flows through the drain valve
to the drain line. The backwash flow rinses the excess brine from
the resin bed after the brine/slow rinse so that you do not get
“salty” water after going back into service.
Brine Tank/Cabinet Refill: After backwash, hard water refills the
brine tank/cabinet through the brine valve to make brine solution
for the next regeneration.
Adjustable Regeneration Frequency:
This valve allows for the adjustment of regeneration
frequency based on inlet water hardness. This improves
performance and reduces water consumption. The
integrated system meter tracks the volume of water
processed and after the adjustable set-point has been
reached, the regeneration process begins.

System Maintenance and Install Guidelines
Adding Salt
Ensure that the salt level in the brine tank or cabinet is always above
the water level.
Use a quality grade of block or pellet salt processed especially for use in
water softeners. DO NOT USE ROCK SALT.
Water Pressure
Inlet water pressure range of 1.5 – 8 bar (22 – 116 psi) is required for
valve to operate effectively.
Existing Plumbing
Existing plumbing should be free from lime and iron buildup. Replace
plumbing that has heavy lime and/or iron buildup. If plumbing is
clogged with iron, install a separate iron filter unit ahead of the water
softener.
System By-pass
Always provide for the installation of a by-pass valve if unit is not
equipped with one.

Manual Regeneration
Using a #2 Phillips screwdriver, push down firmly on the softener valve
screw (see page 7) and slowly turn clockwise, listening for four (4)
clicks to start the regeneration. At this point you should hear water
begin to run through the system. If you do not hear water running
through the system, the disc has not been advanced far enough.
NOTE: If your hot water tank has refilled with hard water, it may take
several days for it to empty and for your water to feel soft again.
CAUTION
Do not exceed water pressure of 8 bar (116 psi).
Do not exceed water temperature of 50°C (120°F).
Do not subject unit to freezing conditions.
Cold Weather Protection
If your Sumo water system is installed outside or in an area that is not
heated, you may want to take precautionary measures to prevent
damage to your unit from freezing.
NOTE: Monument Water Systems’ warranty doesn’t cover damage to
your system due to freezing. If you have questions about your
Sumo water system, or if you suspect that it isn’t working
properly, contact your authorized Monument Water Systems
representative.
Sanitization
After installation, or if water is not used for >30 days, sanitization of the
system is recommended.
Regenerate system. After regeneration, go through sanitization
procedures.
Mix 1 oz. of household, unscented bleach with 1 U.S. gallon of water
in a bucket.
Disconnect brine line from brine valve.
Place brine line in bucket with diluted bleach solution.
Place system into brine draw.
Draw the 1 U.S. gallon of solution, then put unit into by-pass.
Let bleach soak tank for 60 minutes.
Reconnect brine line to brine tank.
Open by-pass valve, continue with system regeneration cycle.
After cycle is complete, repeat the backwash cycle.
Return unit to service.

Commonly Asked Questions
There has been a drop in my home’s water pressure. What can be the
cause?
A reduction in your home’s water pressure can indicate that it is time to
change your prefilter. If you do not have a prefilter with your system or
changing the filter has no effect, contact your authorized Monument
Water Systems representative.
My system seems to be regenerating more frequently. Is this normal?
Remember, your Sumo system is demand-operated, adjusting
automatically to your water usage. If you do not think that your water
usage has increased due to extra house guests, additional laundry or
some other reason, check for any leaky plumbing, dripping faucets or
running toilets, all of which can contribute to more frequent
regenerations.
My water doesn’t seem soft. How can I be sure that my system is
regenerating properly?
Be sure that the water supply to the softener is not by-passed. Follow
the instructions on page 9 to manually regenerate the softener tanks. If
the unit does not begin advancing to the next regeneration
automatically, please contact your Monument Water Systems
representative for further assistance.
I can hear my Sumo system running or regenerating during the day. My
old softener only used to run at night. Is this normal?
Unlike traditional water softeners, Sumo systems operate on demand
based on your water usage, without timers or electronics. So your
system regenerates whenever necessary, at any time of day.
How will I know when it is time to add salt?
Lift the lid of the cabinet to check the level of salt. If you can see water,
it is time to add salt. You can add salt anytime there is enough room to
accommodate additional blocks or pellets.
Is it OK to drink soft water?
Yes, soft water is OK for drinking and cooking. If your softener
regenerates with sodium chloride (salt), keep in mind that there will be
a small amount of sodium added to the softened water. People who are
on sodium restricted diets should consider the added sodium as part of
their overall sodium intake.
♦
If at any time you feel your Sumo water system is not operating
properly, put the system in by-pass and call your Monument Water
Systems representative.
