Suburban water heater anode replacement
I pulled and inspected the anode rod yesterday. It obviously needs to be replaced. My question is the replacement rods I see online are substantially larger in diameter. Was my anode that large when new?

Yes, a new one is larger than that one.

That looks like it has 40+% left. But as long as it is out, go ahead and change it. They are inexpensive.

So are you telling me that rod was bigger? Holy crap Carl, I had no idea. 5 trailers out of 7 that had a water heater and I never touched the anode rod.... 
I thought it was small and collected crap.

When you install a new one don’t over tighten it. They have 3/4” NPT pipe threads which are basically self sealing. Two wraps with Teflon tape, snug it in, and maybe another quarter to half turn with a ratchet/socket.
