Water Heater Drain Valve

Water Heater Drain Valve
Have a water heater with a leaky drain valve.
Want to replace it.
Brand: Hoyt
I know Hoyt is out of business but I just
want to replace the valve and would
appreciate anyone that would list the
steps in the replacing the valve.
Do I have to turn the water off at the main ?
Do I have to shut the WH off ?
These are a few of my concerns.
Thanks for any help you can provide.

1. Turn off main unless there is a shutoff at the water heater.
2. Turn off water heater or flip circuit breaker.
3. Drain tank.
4. Remove fitting and see what it needs.
BUT, before you do that; if the valve is merely leaking out the spout, why not just cap it with a screw-on cap and washer?

By "drain", we assume that you're talking about the drain spigot at the bottom of the heater, and NOT the temperature-and-pressure relief valve at the top of the heater.
You can cap off the drain spigot at the bottom, but do NOT plug off the T&P valve. That can cause a major steam explosion if the heater malfunctions.

Tow Guy,
Thanks for your help. Since this is a very
slow leak from the spout I think I'll cap it
for now. Think Home Depot should have what
I need to do that.
Now I can focus on striper fishing.
Thanks again,

Thank you for your help. I think capping the
Drain Valve (at the bottom of the tank) is the
answer for now since this is a very slow leak.
If I can't find a cap at HD then I'll go to
a plumbing supply.
I also appreciate your concern as to which
valve I was talking about. I bet there are
a lot of folks out there that could very
easily make that mistake causing a serious
explosion.
Time to go fishin
Thanks again,
