I was going to add one in my kitchen, but realized a dedicated circuit is a must, and since I'm a 2 story on a slab I gave up on that dream.

Anyone ever see fluctuations in their hot water temperature?

I've noticed that sometimes (very rare) my shower isn't as hot as usual and trying to diagnose if it's me, my 15 y/o water heater is on it's way out, or it's something else. I know I should replace the water heater even though visually it's in great shape. Only thing I can think of is I was afk so didn't run the hot water for 2 days and maybe things cooled down in the tank? Or is this a sign of failure.

I'm sure the anodes inside are seeing wear, but it may be to the point that if I try to replace them things just fall apart completely.

Most shower valves are pressure balance valves, so anything varying pressure on either hot or cold will make the temp bounce. Can't really diagnose your hot water heater that way. Maybe turn a tap all the way hot and let it purge for a few minutes so you know you're getting tank hot water, and then see what you're getting there? Probably too hot to touch though.

Better way is probably to drain it and see what happens after it fills back up. As long as it recovers in a reasonable time, should be OK.

You may have sediment collecting in the bottom that is around the element and reducing the ability to transfer the heat to the water.

Or you may have an intermittently working element.

When we replaced our 15yo water heater (which actually was still working just fine), we went with a hybrid water heater.

Have had it just a hair shy of 3 years and have been very happy with it.

It uses about 25% of the power our old one used. And I like my showers scalding, so I have the temp turned up to 135F-140F depending on time of year.

Can you change the water line running to the sink? If the supply is 1/2" a 3/8" will reduce time by roughly half. If it's in your slab...sorry.

Edit: I know they have the 1 and 2 gal ones. I just don't want to give up that much space for the hot water coming on 45 seconds sooner.
Work has under sink tankless heaters, plugged into 110V. They also have an adjustment knob for regulating temperature. This is the sort of thing I'm looking for.
I have the dishwasher outlet right next to the kitchen sink and can grab power from there.

Unfortunately I cant change pipes. The ones going to the kitchen must be on the 1/2 size.
That could be why previous owners upped the water psi to the max on the regulator.
Hint: Dont, unless you want leaky toilets and faucets.

I think its recommended to drain the tank once a year to get rid of sediment.

Last place I used to rent, I could connect the garden hose to the water heater and use that for washing the car inside during winter. Worked great The water contained so much sediment, it looked white. I may have done the landlord a favor in draining the water heater.

I need to drain my tank. I'd guess the steps are cut off the power first. Do you turn off supply and drain, or do you leave supply on and flush?

It's pretty common in downtown B'more on rowhouses.

I would suspect that was there because it's a dual zone HVAC system, that is probably the upstairs condensor.

I think this covers it


Turn off gas if you have a gas water heater or electricity if you have an electrical one.
Allow the water heater to cool down for a while
Shut off water supply
Turn on the hot water from a nearby faucet to prevent a vacuum from forming and allowing the tank to drain easier.
Attach a hose to the drain valve and run the hose to a drain or empty bucket
Drain the water heater tank by opening the drain valve and allow the water to flow until it stops, you may have to empty a bucket several times during this process. The water can be very hot at this stage unless you let the water heater sufficiently cool down, be careful!
Flush the tank by reopening the cold water supply and allow this to drain. Do this a couple of times to rid of all of the sediment.
Close the drain valve
Fill the water heater tank by reopening the water supply valve
Power up the water heater

I've always turned off the power and supply, and then just drain the tank.

Once it's empty, you can turn the supply back on and flush it a bit more if you like just to get any last dregs out.

I need to drain my new one as well.

My old one I drained after a couple of years because I needed to move it. And then a couple of years after that I drained it to move it again. So it got flushed early in its life.

Last time I did it I drained the water right away and used the hot water to kill some weeds right outside the garage door.

Thanks. I'm past 3.5 years now, probably should have gotten on this sooner. Along with exercising all my shut-offs.

I just use it hot without letting it cool down to clean out my sump pit.

Maybe I'll just shut the power off the next time the kid is in the shower. When she screams I know it's safe to drain the tank

This didn't work like expected.

Source: 8yo and me tried to do this to the 5yo the other day and the mixing valves just don't allow it. Basically just shuts it all down to a dribble. Hilarity did not ensue, but at least he finally got out of the shower.

Those are good mixing valves.
Back at home we used to have an online water heater that was right at the shower outlet.
Hilarity would ensue every time someone decides to use the garden hose.
Super hot water due to lower flow.

That sounds like you have a thermostatic valve. They are worth every penny.

I have two girls. I put a valve on the outlet of the water heater. So I can shut it off if they take too long.

Alright dudes, I would like to put brick in these channels.




Couple of questions:
Can I just take some of that DG out, dump mortar in there and use the thin brick pictured?
Do I use some type of thinset instead and then just grout around like a normal application?
Would the just dumping mortar and smashing them in there work better with full bricks?

I'm looking for the least amount of hassle/labor since I'm going to tackle this myself.

Meaty?


Finally got the fireplace and step finished after 7 months.

I would probably dig slightly further down. Loose gravel- mortar- bricks.

I was thinking about this as well. Digging it out a bit and the putting sand or something in there and compacting it a bit for a base.

Does that seem like a good idea?
