Installation Guide
Every OMGEN system is designed for simplicity. Whether you're a DIY enthusiast or prefer professional help, these step-by-step guides will walk you through restoring life to your water.
Tools Required
Step-by-Step Instructions
-
1
Shut Off Cold Water Supply
Locate the cold water shut-off valve under your sink. Turn it clockwise until fully closed. Open the faucet to release any remaining pressure, then place a bucket or towel beneath the connection point.
-
2
Install the Dedicated Faucet
If your sink has a pre-drilled accessory hole (soap dispenser opening), use it. Otherwise, drill a ½" hole in the countertop or sink deck. Insert the faucet stem through the hole, secure from below with the mounting nut and washer. Hand-tighten, then snug with a wrench — do not over-tighten.
-
3
Mount the Filter Housing
Choose a location inside the cabinet with enough clearance to change filters (at least 4" below the housing). Mount the bracket to the cabinet wall using the included screws. Slide the filter housing onto the bracket until it clicks.
-
4
Connect the Feed Water Line
Disconnect the cold water supply line from the shut-off valve. Attach the included T-adapter to the shut-off valve. Reconnect the original supply line to one side; connect the ¼" tubing (included) from the T-adapter to the filter's "IN" port. Push the tubing into the quick-connect fitting until you feel a click.
-
5
Connect the Output to Your Faucet
Run the ¼" tubing from the filter's "OUT" port up to the dedicated faucet stem. Push the tubing into the faucet's quick-connect fitting. Ensure all connections are snug and the tubing has no sharp kinks.
-
6
Flush & Test
Turn the cold water supply back on slowly. Check all connections for leaks. Open the dedicated faucet and let water run for 5 minutes to flush the system and activate the media. The water may appear cloudy initially — this is normal carbon fines and will clear quickly.
⚠ Safety Tips
- Always shut off the water supply before starting installation
- Use Teflon tape on all threaded connections to prevent leaks
- Wear safety glasses when drilling countertop holes
- Do not use hot water through the system — cold water only
- Flush for a full 5 minutes before drinking
Tools Required
Step-by-Step Instructions
-
1
Shut Off Main Water Supply
Locate and close your home's main water shut-off valve. Open the lowest faucet in the house to drain remaining water pressure. Place buckets and towels in the installation area. Turn off the water heater to protect it during the process.
-
2
Choose Installation Location
Install the system on the main water line after the shut-off valve but before it splits to the water heater and house. Choose a location that is easily accessible for filter changes, protected from freezing temperatures, and has adequate clearance (at least 12" above and below the unit).
-
3
Mount the System Bracket
Secure the mounting bracket to the wall using the included hardware. Use a level to ensure it's perfectly straight. The bracket must be secured to studs or use appropriate anchors for your wall type — the system is heavy when full of water.
-
4
Cut Into the Main Water Line
Measure and mark cut points on the main line. Cut the pipe using a pipe cutter (copper) or hacksaw (PVC/PEX). Install shut-off valves on both the inlet and outlet sides — this allows future maintenance without shutting off the entire house.
-
5
Connect Inlet and Outlet
Apply Teflon tape and pipe thread sealant to all threaded connections. Connect the inlet (from main) to the system's "IN" port. Connect the "OUT" port to the house supply line. Follow the flow direction arrows on the unit. Double-check all connections are tight.
-
6
Install the Bypass Valve
Connect the included bypass valve between inlet and outlet shut-offs. This critical component allows water to flow to your home during filter changes or maintenance without interrupting service.
-
7
Flush, Test & Commission
Slowly open the inlet valve. Check every connection for leaks — tighten as needed. Once leak-free, open the outlet valve. Run water through the system for 15–20 minutes to flush media and purge air. Open faucets throughout the house one at a time to clear air from the lines. Re-enable your water heater.
⚠ Safety Tips
- Turn off the water heater before shutting off the main supply to prevent dry-firing
- If you have a well pump, turn it off at the breaker before starting
- Check local building codes — some jurisdictions require a permit for whole-house systems
- The system is heavy — have a helper when mounting to the wall
- Do not install in locations where temperatures drop below 40°F (4°C)
Tools Required
Step-by-Step Instructions
-
1
Remove Your Existing Shower Head
Unscrew your current shower head from the shower arm by turning it counter-clockwise. If it's stuck, wrap a cloth around it and use an adjustable wrench for leverage. Clean any old Teflon tape or buildup from the shower arm threads.
-
2
Apply Teflon Tape to Shower Arm
Wrap 3–4 layers of Teflon tape (included) clockwise around the shower arm threads. This ensures a watertight seal and prevents leaks at the connection point.
-
3
Attach the OMGEN Shower Filter
Screw the OMGEN filter housing onto the shower arm by turning clockwise. The "IN" end connects to the shower arm. Hand-tighten firmly — you should not need a wrench. Ensure the included rubber washer is seated inside the connection.
-
4
Reattach Your Shower Head
Apply Teflon tape to the filter's "OUT" threads. Screw your original shower head onto the filter's outlet. Hand-tighten firmly. The installation order is: shower arm → OMGEN filter → shower head.
-
5
Flush & Enjoy
Turn on the shower and let it run for 2 minutes to flush the media. Check both connections for drips — hand-tighten further if needed. You're done. Your skin and hair will feel the difference immediately.
⚠ Safety Tips
- Do not over-tighten — hand-tight is sufficient for shower connections
- Replace the shower filter cartridge every 6 months or when flow rate decreases
- The filter housing is designed for standard ½" shower arm threading (universal fit)

Step-by-Step Instructions

1
Shut Off Well Pump & Drain Pressure
Turn off the well pump at the circuit breaker. Open the lowest faucet in the house to drain pressure from the system. Turn off the water heater. Allow the pressure tank to depressurize fully before beginning work.
-
2
Test Your Well Water
Before installation, test your well water for pH, iron, manganese, hardness, and sulfur. This data helps OMGEN customize your media blend. If you haven't already, request a free water analysis through our contact page. The Well Water System uses the WellGuard Blend specifically engineered for groundwater contaminants.
-
3
Choose Installation Location
Install after the pressure tank but before the water heater and house distribution. The system needs: indoor location protected from freezing, minimum 15" clearance above for filter changes, easy access to a drain for backwash (if applicable), and proximity to an electrical outlet for UV stage (if included).
-
4
Install Pre-Filter Sediment Stage
The Well Water System includes a sediment pre-filter to protect the main media from heavy particulates. Mount the pre-filter housing first, upstream of the main unit. Connect with the included fittings. This stage captures sand, silt, and rust particles common in well water.
-
5
Mount & Connect the Main System
Secure the main system bracket to the wall. Cut into the water line and install shut-off valves on both inlet and outlet sides. Connect the pre-filter output to the main system input. Connect the main system output to the house supply. Install the bypass valve assembly between inlet and outlet.
-
6
Connect Drain Line (If Equipped with Backwash)
If your system includes an automatic backwash valve, connect the drain line to a nearby floor drain, utility sink, or exterior drain. The backwash cycle flushes accumulated contaminants and regenerates the media — typically programmed to run once per week during off-hours.
-
7
Commission the System
Open the inlet valve slowly. Check every connection for leaks. Open the outlet valve. Restore power to the well pump. Run water through the system for 20–30 minutes to flush all media stages and purge air. Open faucets throughout the house to clear air pockets. Check water pressure with a gauge — should be within 5 PSI of pre-install pressure. Re-enable the water heater.
⚠ Safety Tips
- Always turn off the well pump at the breaker — not just the pressure switch
- Well water systems are heavier than municipal systems — ensure proper wall mounting
- If your well has high iron (>3 ppm) or sulfur, contact OMGEN for a custom media recommendation
- Check local health department requirements for well water treatment systems
- Test your water annually after installation to verify system performance
- Keep the area around the system dry and accessible at all times
