Disconnect all power
Turn off the breaker at the main panel. For gas heaters, set the control dial to pilot. Verify with a non-contact voltage tester if available. Never work on electrical fittings with the breaker on.
DIY Installation Guide
Install the aurauto® TGR2-X1 in 5 Minutes
Before you start
Most homeowners complete this install in under five minutes. There is no plumbing rework and no electrical permit required. Read through every step once before touching the tank so you do not get caught on a missing tool.
Critical safety warnings
- Disconnect power at the breaker before opening any panel or touching wires.
- For gas heaters, set the control dial to the pilot position and confirm the gas is off.
- Water in the tank may be scalding. Wear closed-toe shoes and keep children and pets clear.
- Do not apply Teflon tape to the hex head threads —only the tank-side threads.
- Confirm your water heater has a dedicated anode port. Bradford White and some other brands do not.
What you need
1-1/16" socket wrenchRequired. Any other size will round the hex.
Channel-lock pliersOptional —only if the old rod is stuck.
Teflon (PTFE) tapeIncluded in some kits. 3 to 4 wraps clockwise.
Floor drain or bucketFor the 2 to 3 gallons you drain.
Standard 110V outletWithin 12 ft of the heater, for the 12V adapter.
The TGR2-X1 should be installed only in tanks with a dedicated anode port. Most Bradford White residential heaters mount the anode in the hot water outlet and are not compatible. See the Bradford White compatibility guide before installing.
Step-by-step install
2
Close the cold water valve
Turn the cold water shut-off valve clockwise until fully closed. This stops the tank from refilling while you drain. Open a hot tap in the house to break the vacuum so water can flow out of the drain valve.
3
Drain 2 to 3 gallons
Connect a garden hose to the drain valve at the bottom of the tank. Run it to a floor drain or large bucket. Open the drain valve and let 2 to 3 gallons out —enough to drop the water level below the anode port. You do not need to drain the whole tank.
- Water level must be below the anode fitting before you open it.
- Water may still be hot. Wear gloves and keep skin clear of the stream.
4
Remove the old anode rod
Set your socket wrench to a 1-1/16" (about 27 mm) socket. Fit it over the anode rod hex head. Turn counter-clockwise. Back the rod out by hand once it is loose. Pull the factory rod straight out. If the rod is stuck, apply penetrating oil, wait 15 minutes, and try again with a longer breaker bar.
5
Wrap threads with Teflon tape and install
Wrap the TGR2-X1 threads clockwise (looking at the end of the threads) with 3 to 4 wraps of Teflon (PTFE) tape. Do not skip the wrap —skipping it is the single most common cause of post-install drips. Screw the rod in by hand clockwise until snug, then tighten a quarter-turn more with your socket wrench.
- Tape direction matters: clockwise only.
- Hand-tight first, wrench snug —not gorilla-tight.
6
Reconnect power
Close the cold inlet slowly so the tank refills without hammering. Plug the 12V adapter into any standard 110V outlet. The green LED on the adapter confirms the unit is operating. Restore the breaker for the water heater. Wait 30 minutes, then run a hot tap. The water should now be under powered titanium protection.
Confirm the install worked. After 30 minutes, run a hot tap for 2 to 3 minutes. If the water smells like rotten eggs (sulfur) before the install and goes neutral within 24 hours, the unit is working. If you still smell sulfur after 48 hours, the unit may not be receiving power —check the adapter LED.

Frequently asked questions
Do I really need a 1-1/16 inch socket wrench?
Yes. The TGR2-X1 hex head is sized for a 1-1/16 inch (about 27 mm) socket. Any other socket will round the head off and make future service difficult.
What if my old anode rod is stuck?
Older tanks can corrode the threads so that the factory rod becomes stuck. Apply a penetrating oil like PB Blaster, wait 15 minutes, then try again with a longer breaker bar. If it still will not move, contact a licensed plumber.
Do I need to drain the whole tank?
No. Draining 2 to 3 gallons is enough to drop the water level below the anode port. Full draining is unnecessary and adds a 30 to 60 minute recovery time once you refill.
Can I install TGR2-X1 in my Bradford White water heater?
Most Bradford White residential heaters mount the anode rod in the hot water outlet rather than a dedicated port. The TGR2-X1 does not fit that configuration. See the Bradford White compatibility guide before installing.
Which direction should Teflon tape be wrapped?
Clockwise when looking at the end of the threads. Wrapping counter-clockwise causes the tape to unravel as you tighten the rod.
How will I know the TGR2-X1 is working after install?
The 12V power adapter has a small green LED that lights up when the unit is receiving power. If you have a multimeter, you can also verify approximately 12V DC at the rod top terminal.
Do I need a permit or electrician for this install?
No permit is required in any US jurisdiction. The TGR2-X1 plugs into a standard 110V outlet and draws well under 1 watt, well below the threshold for a hardwired electrical permit in any state.
