System Installation

Pre-Installation Considerations

•  A minimum of 25psi of water pressure is required for regeneration 

valve to operate effectively.

•  A continuous 115 volt, 60 Hertz current supply is required. 

Make certain the current supply is always hot and cannot be 

turned off with another switch.

•  Condition of existing plumbing should be free from lime and 

iron buildup. Piping that is built up heavily with lime and/or iron 

should be replaced. If piping is clogged with iron, a separate 

iron filter unit should be installed ahead of the water softener.

•  The softener should be located close to a drain.
•  Always provide for the installation of a bypass valve.
•  The full weight of the plumbing system must be supported by 

pipe hangers or other means.

•  Do not install the system where it would block access to the water 

heater, main water shutoff, water meter, or electrical panels.

•  Install the system in a place where water damage is least likely 

to occur if a leak develops.

•  If applicable, use di-electric unions where dissimilar metals  

are present.

The main control valve and all plumbing connections have 

right-hand threads. Turn clockwise to install.

NOTICE

If O-ring lubricant is required, only use a silicone based 

compound formulated for potable water O-ring applications. 

Watts recommends Ordering Code #68102757 Silicone 

Lubricant. The use of other types of lubricants may attack 

the control’s plastic or rubber components. Petroleum-based 

lubricants can cause swelling in rubber parts, including  

O-rings and seals.

NOTICE

WARNING

!

Do not exceed water pressure of 125psi (8.6 bar). Do  

not exceed 110°F (43°C). Do not subject unit to freezing  

conditions.

General Installation Instructions

1.  Turn off water heater(s).
2.  Turn off the main water supply to the building and open a treated 

water faucet (cold and hot) to relieve any pressure within the 

plumbing system.

3.  Place the mineral tanks into their final position for installation. 

Make sure that the location is level and sturdy enough to  

support the weight of the system once it is in operation. 

4.  Unloaded mineral tanks will need to be loaded with resin and 

gravel media following the instructions below:

4a.  Inspect the distributor screens for damage, and make  

sure the screens are present before loading the mineral 

tanks with media. Before proceeding with installation, 

replace any damaged components immediately.

4b.  Cap the top open end of the distributor tubes with tape 

and plastic sheeting to keep all media and foreign debris 

from entering the distributor tubes. This cap must be 

secure and not come off during media loading.

4c.  Place the distributor tubes, screen end down, into the mineral 

tanks and center them in the bottom. The top of the dis-

tributor tubes should be flush with the top of the tanks. Test 

the tapes cap to make sure they can not come off during the 

media loading process.

4d.  Make sure the plastic and tape caps are secure to the top 

of the distributor tubes, place a funnel on the top of the 

tanks and load first the gravel then the softening resin into 

the tanks. The caps must not come off of the distributor 

tubes during the loading of the media.

4e.  Remove the funnel from the top of the tanks and plastic 

caps and tape from the top of the distributor tubes. DO 

NOT PULL UP ON THE DISTRIBUTOR TUBES when 

removing the caps. The distributor tube tops must remain 

flush with the top of the tank.

4f.   Clean any media from the threads and top of the mineral 

tanks. Media in the threads and on the O-ring sealing sur-

face of the tanks can cause tank thread damage and pre-

vent the control valve’s O-ring seal from sealing properly.

4g.  Lubricate the O-rings on the bottom of the control valve 

(distributor tube port O-ring and top of tank O-ring). Use 

nonpetroleum based silicone lubricant only. For PWS15T 

series systems press the factory suppled black upper  

diffuser into the base of the control valve and then repeat 

this step using the second tank adapter.

4h.  Place the control valve on top of the tank. When per-

forming this step, seat the top of the distributor tube inside 

the distributor port located on the bottom of the control valve 

first, then press the control valve down until the control valve 

threads come in contact with the tank threads. This ensures 

that the distributor tube is properly seated into the bottom 

of the control valve. Repeat this step using the other mineral 

tank and the second tank adapter. 

4i.   Tighten the control valve onto the tank with a clockwise 

rotation. Be careful not to cross thread the control valve to 

tank connection or over tighten it. A hand tight fit is appro-

priate for the control valve torque. DO NOT use a wrench. 

Tank or control valve damage could result. DO NOT apply 

thread sealant or plumbing tape on the control valve to 

tank threaded connection. Repeat this step using the other 

mineral tank and the second tank adapter.

4j.  Install the interconnecting tube assembly from the control 

valve to the second tank adapter. For PWS10T series sys-

tems tighten clips with screws provided using a nut driver. 

For PWS15T series systems tighten flanges (X2) to control 

valve and second tank adapter using a wrench.

5.    

Meter Installation:

 On PWS10T series systems the meter is 

pre-installed by the factory. Proceed to installation step 7. For 

PWS15T series systems, apply a suitable thread sealant to the 

male threads of the flow meter and with the meter’s direction of 

flow arrow pointing in the direction of water flow, install the meter 

directly into the outlet port of the system control valve. 

6.  For PWS15T series systems, rotate meter clockwise to tighten, 

by gripping the meter on the end connector that attaches to the 

control valve with a wrench, and continue to tighten the flow meter 

end connector until tight. Then rotate plastic meter body so the 

meter cable can be aligned and inserted into the meter’s cable 

port. DO NOT grip on the plastic meter body with the wrench 

when installing the flow meter. 

7.  For PWS10T series systems, attach bypass valve assembly using 

clips and screws provided. Hand tighten screws with a nut driver.

If 4" X 21/2" PVC tank bushings are included with the system 

to adapt the control valve base to a larger control valve tank 

connection, ensure the bushings are tightened, fully hand 

tight, into the tanks at this time.
