Hot water overflow

[Ned]

Ask me at Moab about my adventure in draining the HWT last summer.

 

[Tom]

Will do Ned. Do I see a HFWPOH award?

 

[Ned]

No, just a simple job gone awry.  It involves the relief valve, too, and the rule "Never start a plumbing job on a Sunday".

 

[Karl]

I'll second that, and never remove (or try to remove) a nylon drain plug unless you already have a new one. And plan on spending a few hours removing the old one after you've twisted the head off it with a wrench.

 

[Ned]

I broke the nylon plug in Louisiana a few years ago.  This episode involved the relief valve.

 

[Ron]

I broke the nylon plug in Louisiana a few years ago.? This episode involved the relief valve.

Does that mean rule two is to have a spare nylon plug when ever you drain & flush the tank? : ??? :

 

[Ned]

No, have a new, brass, plug on hand first.  I got one with a petcock for draining and anode rod too.

I remove the  the plug to flush the tank.  I don't see how the tank can be flushed though a petcock.  I do keep a spare nylon plug on hand.  and have replace one once just because I figured it was time.  However I still have the old plug on board somewhere to just in case.

I totally agree with Ned. Get a brass petcock w/anode. You can use the petcock to renew the "head" by opening it and the pressure relief valve to suck some air in, or remove it completely for flushing. Don't forget your teflon tape. I would also recommend you find that old nylon plug and toss it.
