Overview
Thank you for your purchase of a Watts Whole House Water Filter. Water quality concerns are quickly becoming more of
a focus for the public. This Watts whole house water filter has been designed and tested to provide you with a higher
quality of water.
This filter is designed to reduce the amount of sediment that would normally enter your home water system. Reducing
the amount of sediment in your home water system will allow your fixtures and water use appliances to work better.
It is important to change out your filters at the recommended intervals as indicated in this system manual. When
replacing the filter elements, pay special attention to any cleaning instructions. Should you have any further questions
please refer to our web site at www.premierH2o.com or call our customer service department at 1-800-752-5582.

Figure 1: There are several ways to plumb your whole house Filter into your existing
water line. The diagram above is the basic install layout.
Step 1: Determine the size of the incoming water line you will be tapping into.
Step 2: Determine the pipe material (Copper, Pex, CPVC, or other)
Step 3: Make sure water flow direction coincides with the “IN” and “OUT” ports marked on the unit.
NOTICE
For copper we recommend using brass 3/4” MPT x (plumbing size) 1/2” or 3/4”
compression style fittings. For all other types check with your plumbing professional.
Step 4: Make sure to use teflon tape on all male pipe threading used.
CAUTION
Make sure not to overtighten threaded port to unit!
Step 5: Shut off main water supply and open a faucet beyond the connection to relieve water pressure.
Step 6: Determine placement of the unit. The amount of pipe to be removed will be dependant on the type of
fittings used.
NOTICE
This unit must be installed vertically with the lid on top.

Step 7: Cut the water line where the Whole House Filter is to be installed. Copper plumbing needs to be cleaned
& de-burred of any imperfections. Make sure the installation location allows for easy servicing of the
system, including a clearance beneath the filter bowl for filter changes.
Step 8: Plumb waterline to system. Make sure that the flow direction is correct through the filter system.
Start Up
Step 1: Make sure the valve on the lid is turned to “FILTER”.
Step 2: Open a faucet downstream of the Whole House filter unit.
Step 3: Slowly turn on main water supply until faucet downstream is steadily flowing.
Step 4: Turn off faucet and check for leaks at your connections. Monitor for leaks for 24 hours after installation.
Operating Instructions
This whole-house filter features a Valve-in-Head design. This allows you to control water flow through the unit without
additional hardware.
Valve Operation (See Label for Position)
BY-PASS Allows water to continue to flow through the house NOT utilizing the filter.
OFF Shuts off water before the filter.
FILTER Allows water to flow through the house utilizing the filter.
Note: In all three modes the unit will remain under pressure.
Suggested Maintenance
This whole house filter can use 5, 10, 20, or 50 micron sediment filters. This kit includes three (3) 50 micron filter. The
recommended filter is a 50 micron. The recommended time for replacing your filter is every three (3) to six (6) months
depending on your incoming water conditions. If your water contains more sediment you may be required to change
your filters more often. Failure to change filters regularly will reduce water pressure & flow. Visually check filter for
sediment or dirt loading.
