1
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
3 core steps · 7 detailed actions · about 5 minutes of hands-on work once the tank is prepared.
Before you start
Most homeowners complete the hands-on portion 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.
Safety first — read before you start
- 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 which kit matches your tank: Standard Kit for a dedicated anode port, or Bradford White Kit for hot-water-outlet tanks.
What you need
Three groups: tools you bring, shared parts in every kit, and the one kit-specific part that differs between Standard and Bradford White.
Tools you prepare
Sockets ship in your Standard Kit — bring only the three tools below, plus your ratchet to use with the included sockets.
Ratchet wrenchUse with the included 1-1/16" and 1-3/16" sockets.
Robertson (#2) screwdriverFor panel screws and square-drive fittings.
Universal pliersOptional — if the old rod or outlet is stuck.
Also prepare: 1-1/16" + 1-3/16" sockets
Not in your BW Kit box — same sizes as Standard Kit. Hardware store or your existing set.
In every kit (in the box)
Same three parts ship in both Standard Kit and Bradford White Kit.
1× TGR2-X1 anode rodPowered titanium anode — the core unit.
1× power adapter12 ft cord · 110V to 12V. Plugs into a standard outlet near the heater.
1× Teflon (PTFE) tapeWrap rod threads clockwise — 3 to 4 turns.
Kit-specific part — the only difference
Your Standard Kit includes 1-1/16" + 1-3/16" sockets in the box.
Standard Kit Only
1-1/16" + 1-3/16" sockets
Use with your ratchet wrench. 1-1/16" removes the factory rod; 1-3/16" installs the TGR2-X1.

Step-by-step install
Detailed actions below. Steps 1–2 prepare the tank. Steps 3–5 swap the rod. Steps 6–7 power on and verify.
Phase 1
Prepare the tank
Power off, stop water flow, and drain enough to clear the anode port.
2
Close water and drain
Step 2-1
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.
Step 2-2
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.
Phase 2
Swap the anode rod
The core install — remove the factory rod and install the TGR2-X1.
3
Remove the old anode rod
Fit the included 1-1/16" socket on your ratchet wrench. Place it over the anode rod hex head at the dedicated anode port. 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 like PB Blaster, wait 15 minutes, and try again with a longer breaker bar.
4
Wrap threads with Teflon tape
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.
- Tape direction matters: clockwise only.
5
Install the TGR2-X1
Screw the rod in by hand clockwise until snug, then tighten a quarter-turn more with your ratchet and the included 1-3/16" socket. Hand-tight first, wrench snug — not gorilla-tight.
3
Remove the hot water outlet assembly
With water off and the tank depressurized, unscrew the hot water outlet nipple on your Bradford White tank to access the factory anode rod inside. Keep track of any existing fittings you remove. If the assembly is stuck, use channel-lock pliers gently — do not crush soft copper.
4
Wrap threads with Teflon tape
Wrap the TGR2-X1 threads clockwise with 3 to 4 wraps of PTFE tape before assembling the Bradford White tee fittings.
5
Install with tee fittings
Remove the factory rod. Install using the three pre-assembled tee fittings from the Bradford White Kit, following the branch shown in the install video. Hand-tight first, then snug — do not over-tighten.
- Use all three tee fittings supplied in the BW kit.
- Confirm hot outlet orientation matches your tank before final tightening.
Common issues during install
- Old rod won’t budge: PB Blaster, wait 15 min, longer breaker bar. Still stuck? Contact support.
- Drip at the fitting after install: Re-check PTFE wrap direction (clockwise only) and hand-tighten before wrench-snugging.
- Green LED off: Confirm outlet power, adapter connection, and ground clip on bare tank metal — not paint.
Phase 3
Power on and verify
Refill the tank, attach the ground clip, plug in, and confirm the green LED.
6
Refill and attach ground clip
Close the drain valve. Reopen the cold inlet slowly so the tank refills without hammering. Snap the ground clip to bare metal on the tank shell — not painted surfaces.
7
Plug in and verify
Plug the 12V adapter into any standard 110V outlet within 12 ft of the heater. The green LED on the adapter should turn solid when the unit is operating. Restore the breaker for the water heater. Wait 30 minutes, then run a hot tap.
- Green LED solid = power is reaching the rod.
- No LED? Check outlet, clip contact, and adapter connection.
WQA Gold Seal applies to model TGR2-X1. Kit fittings are installation accessories.
Confirm the install worked
After 30 minutes, run a hot tap for 2 to 3 minutes. If the water smelled like rotten eggs (sulfur) before the install, it should go neutral within 24 hours. If you still smell sulfur after 48 hours, the unit may not be receiving power — check the adapter LED and ground clip contact.
Not sure which kit fits your tank?
Most Bradford White residential tanks (40–89 gal) mount the anode in the hot water outlet. Check your layout before you buy.

Frequently asked questions
Do I need the included sockets and my own ratchet?
Standard Kit ships with 1-1/16" and 1-3/16" sockets in the box. You bring the ratchet wrench. Use 1-1/16" to remove the factory rod and 1-3/16" to install the TGR2-X1. Wrong sizes will round the hex head 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 or aurauto support for guidance.
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?
Yes — use the Bradford White Installation Kit on the TGR2-X1 page. It includes tee fittings for hot-water-outlet installation. The Standard Kit is for dedicated ports only. See the Bradford White compatibility guide.
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. Snap the ground clip to bare tank metal. 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.
