I agree but the only thing is they put it on the outside of the house here in Texas. How stupid is that! In the winter of 2020 a lot of our Tankless Heaters froze & bursted. So what I should of said “I would not buy another home with a Tankless Heater on the outside of house”. They’re OK but make sure they’re at least in your garage.

I think that is one of those things you are supposed to but no one ever does. There is a drain at the bottom of the tank. Junk, scale collects in the tank. If, you open the valve and dirt gets stuck in the valve, IT WILL LEAK. The heating element, IF connected to power must be in the water or it will burn out. Ours has not been done in 10 years. Expected life is like 14 years for a hot water heater.

One good thing about that drain is that it's basically a hose bib with a threaded end. If it does develop a leak when you drain it you can simply place a threaded cap on the end and the leak is stopped.

As said we are of the group that never does it. The concern is that dirt will end up in the drain valve and the valve will leak. IF, you only use your home part time, you may find when you first use the hot water it will look rusty. You are not supposed to use normal hot water supply in food.

Can't help it. Honey where are those caps I had down our basement. Don't you remember I tossed them?

Have it in your hand before you open the valve. Or just run out to Lowes and buy one and install it as soon as you get home. Don't over complicate this. lol

Then you are not the one who said to drain it sooner if needed. "If needed" implies there is some indication of need. I was asking that individual what the indication was.

News to me! What hot water supply are you supposed to use in food if not the normal supply in your home???

First of all, the manufacturer of many water heaters in The Villages is Rheem. The Rheem owners manual does not recommend that you drain or flush the water heater. And, second, the drain valve only has an opening of about one half inch when fully opened. That is not nearly large enough to allow very much sediment to be drained out of the tank and it will not create any type of "flushing" action in the tank. Any sediment that has become attached to the inside of the tank or to the heating elements will not be drained out at all. Note that the cold water enters the water heater near the bottom of the tank through a pipe called the dip tube. So, the water normally travels from the bottom of the tank to the top where it exits as hot water.

I would recommend that you also have a rubber washer to insert into the cap. Otherwise, it could leak.

Every time I've bought a cap it has had the washer included.

I got to laugh about going in the basement.

So many times, when I start a project, I figure I got one, then remember it was in the basement, UPNORTH.

Not my experience at all. I have bought pipe caps from Home Depot and Lowes. They were in a loose bin, and they didn't come with washers. They are not really designed to be water tight.

This is what I bought. Rated for 75psi with spikes to 150. Threaded Cap

If you read the reviews several people use them for their leaky water heater valve.

I agree. The important point is that you need to use a washer or it will probably leak.
