    While preparing my new to me pup for the first trip of the year I found the drain threads of my suburban water heater to be corroded and possibly striped to the point where I can't screw in a new anode. Has anyone else come across this problem and know how to fix it? I've looked into thread chasers and taps but the ones I'm finding are almost as expensive as a new water heater. Fortunately I have a bypass valve so it's not a show stopper but it would be nice not to lose 6 gallons of water.

    A new 3/4-14 npt tap should cost you about 20 dollars, try eBay.

    I just checked amazon. There are several choices for a 3/4 NPT tap for $15 to $20. That should clean the threads.

    Also keep in mind that the heater tank doesn't add 6 gallons of useable water capacity. If your fresh tank runs dry, the only way to use that 6 gallons in the heater would be to drain it into a container, bypass the heater, then pour the water into the fresh tank.
