Good evening all.
So I'm getting ready to replace the Anode Rod in the Hot Water Tank.
I had a previous post asking about advise and learned a lot.
One thing I'm also going to do is replace the Drain Valve.
Reason: Going with a Ball Valve to get a lot better flow when I do a 'drain' checking for any sediment.
I have County water and don't expect much sediment, but with using a 3/4" Ball Valve, if their is any
garbage in bottom of Tank, it should come out (more so than with factory drain).
I'm thinking of Galvanic Corrosion if I screw a 3/4 x 3" brass nipple into the steel tank.
Yes, the factory Valve is brass so it may not matter to much.
But I can't help but think that I should use a Galvanized/Steel nipple screwed into the Tank (plenty of Sealant)
and then use a Union for joining dissimilar metal would be the way to go.
Then, attach the Ball Valve to the Union.

Question:
Would anybody be worried about screwing a Brass nipple to Water Tank ? ? ?
I would like to purchase the dielectric union, but there $28.00 each.
I did purchase a 3/4" NPT Tap to clean up any threads when I do the Anode Rod and Drain Valve.
Any other options ?
Thank you.
