Where and How to Install
To be most effective this filter system must be attached to your water line after your water meter and/or main shut off valve and before the water goes anywhere else in the home— especially before your hot water heater. The best installation incorporates by-pass plumbing (described herein) that allows the filter system to be by-passed in an emergency.
Please check entire installation plan for compliance with local building codes before proceeding with installation. If the home is plumbed with galvanized pipe, that pipe should be replaced with copper or CPVC before installing the filter.
In the event there is an in-ground sprinkling system attached near the main shut-off valve this filtration system should be attached after the in-ground sprinkling system and before the water goes anywhere else. If a water softener is present this filter should attach after the softener.
Special Note: The volume of water this filtration system is designed to handle assumes a normal amount of outdoor watering through outside taps. If you desire to avoid filtering water to outside taps then you must bring those lines back to a source point prior to this filtration system. Under normal circumstances this is not necessary due to the capacity of the filter in relation to the average number of gallons used by a single family residence over the normal life of the filter. Resetting the valves to re-route the water will also avoid sending filtered water outside but supplies unfiltered water to all interior taps. It should be noted that chemical free water helps plants too.
Suggested Installation Instructions
Please read and understand ALL instructions BEFORE starting
NOTE: Be sure to use teflon tape where needed. Never use joint compound or pipe dope!
IMPORTANT: Unit must be flushed per instructions before connecting the outlet side!
Steps of installation:
- Apply teflon tape to both ends of the nipple and the MPT (male pipe thread) ends of the two union, ball valve adapters. Remove plugs from main filter.
- Thread the 4” male nipple into the side marked “in” on the main filtration tank and one union, ball valve adapter into side marked “out”. Turn the elbow so the open end is facing down for flushing. (use pliers—tighten to stop—do not over-tighten—hold white adapter while tightening nipple and union ball valve adapter)
- Unscrew jar from pre-filter head and thread the side marked “out” on the pre-filter head to the 4” threaded nipple on the tank. (Tighten to point where jar threads on head point directly down—hold nipple while tightening head.) Screw jar back on pre-filter head without inserting pre-filter cartridge (see step 12)—tighten with pre-filter wrench.
- Thread the other union, ball valve adapter into the side of the pre-filter head marked “in”. (hold pre-filter housing and tighten)
- Turn off water to house by closing main shut-off valve. Open faucet closest to main shut-off valve to relieve pressure and allow pipes to drain. Drainage will be best from tap on same floor as shut off. If not possible, use kitchen sink cold tap.
- Set assembled tank in place.
- Following local plumbing codes and taking into consideration the size and type of your supply line, install a bypass with stop valve as depicted in illustration. This can be soldered copper, Qest fittings, Shark Bites, Seaquest or any other locally approved plumbing materials. Note: some water meters will need to be supported until bypass has been assembled and supply line is reconnected.
- Set filter unit in place. Remove black locking clip and attach piping from the tee closest to the water supply to the elbow on the “in” side (pre-filter side) of the main water filter using locally approved fittings and tubing. Supplied elbow will accept ¾” copper or CPVC pipe. Note: Make sure to push tubing all the way into supplied elbow. White SeaTech elbows have two stops—be sure to press firmly until the tubing reaches the second stop, then replace locking clip. (To remove tubing from elbow, remove clip, hold back ring and pull.)
- With the valve between the tees closed, turn main water valve slowly on so that water begins to fill the pre-filter housing. Let water run at a slow rate until main filter fills (air can be felt escaping from open end) and carbon fines begin spurting from main filter into a bucket held up to catch them (you may want to attach a short piece of 3/4” tubing to the open side of the elbow to facilitate flushing). Fill bucket—turn off main valve—dump bucket in sump or other drain and repeat until all air and carbon fines have been expelled, increasing water pressure each time until it runs clear with main valve fully open. (15 to 20 gallons minimum—it may take more to get all the air out.)
- With main valve turned off, remove black locking clip and turn the elbow in the direction needed to run tubing from the “out” side of the filter to the tee on the other side of the shut off valve using locally approved fittings and tubing. Supplied elbow will accept ¾” copper of CPVC pipe. Note: Make sure to push tubing all the way into supplied elbow. White SeaTech elbows have two stops—be sure to press firmly until the tubing reaches the second stop, then replace locking clip. (To remove tubing from elbow, remove clip, hold back ring and pull.)
- Make sure the in and out valves are in the open position and stop valve between tees on the by-pass tree is in the off or shut position—open faucet as nearby as possible—turn main water shut off valve on slowly allowing all air to escape before you gradually open valve all the way, restoring service to the home.
- The separation of KDF and carbon within the unit has a tendency to trap air. Inserting the pre-filter cartridge after the installation is complete allows the air to escape. Turn valves on both sides of the filter to off. Use red pressure release button on pre-filter to release pressure. Remove pre-filter housing by using the supplied wrench. Dump out water in pre-filter. Insert pre-filter cartridge and re-attach to head. Tighten with wrench then turn the in and out valves to restore water flow.
- Let cold water run to complete the flushing while you clean up. This will allow the residual air in the unit to be forced out. Water may appear cloudy until all air is forced out. The water will usually run completely clear in about 15 minutes.
- After water runs clear—close all open faucets and recheck for leaks.
NOTE: Effects of clean water in shower and laundry will not be realized until hot water tank empties of old tap water and refills with filtered water.
