Question 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?

Oops.

When you're finished, open a hot water faucet and turn on water to tank.

ONLY when tank has completely refilled, turn on power.

Cool

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,

Mike,

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,
