Waste KingAH-780-UL FBA_AH-780-UL Instant Hot Water Tank, White

Others indicated that this was the same as the Frankie Little Butler tank. Here’s photographic proof. What a savings! I only had to transfer over an additional pressure fitting at the top that reduced the fitting to use existing piping. Installation took all of five minutes once I figured out how to remove the existing pressure fittings (thank you YouTube). So far water is hotter and no sputtering (of course we’re replacing a seven+ year old unit). Highly recommended for price, convenience, and performance.

This is my third Waste-King Quick & Hot instant hot water device. The first one was purchased in April 2001; the 2nd in August 2011; and this 3rd one in April 2021. Hence, based on my experience, they have a dependable & useful performance life of approx.10 years. Which is fine with me. The device is relatively easy to install (though it would be helpful to have some basic hands-on plumbing experience) and which for me has performed reliably during the prior 10-year intervals. I recommend the purchase.

Great small water heater

I swapped out a 6 year old unit that began leaking from the center pipe with this one. Overall, an easy swap EXCEPT they changed the center pipe that exits the tank. The old one (right photo) had a built in flange and nut that threaded onto a reducer. The new one (right photo) has just a straight pipe. The instructions say to use a clamp to install the water line. Really? The water line is a smaller diameter than the pipe exiting the tank, so that won't work. Plus, they do not include a clamp. I ended up buying a compression nut and a 3/8" ferrel and re-used the threaded adapter (the silver colored piece) to attach the water line. Why did they do that? I have no idea. Also, when I first tested it water was leaking from the compression nut. I had to reinstall it and make sure the ferrel was at the end of the pipe prior to threading the adapter to the nut. The first time I had installed it the ferrel had slide down too far down the pipe. This is why I HATE plumbing projects. I would have given this 5 stars but gave it 4 for this reason.

I've only had it installed for 3 weeks and on several occasions I notices water spray on the interior of my cabinet door (NOT good for the wood!). I now have a new task to remember when I'm in the kitchen: Open the cabinet door to check if there is moisture. Plus, it's sputtered like a volcano into the sink and onto the counter. I turned the heat down about 1/3 to help reduce this from occurring, but now my water isn't hot enough. I bought this model because I could use the existing Kitchenaid external faucet that I had. (It looks like the same manufacturer made both.) Additional advice: never order anything too far ahead of installation: I realize now that my return window is closed-- in fact it was closed before it was installed.

Great Unit, but be warned, you may have to turn down the heat. It you have it too high it will spew piping hot water out of the valve. The built in pressure release feature does this. Just make sure your not under the spout when this happens. My wife was washing dishes and this thing let loose and she almost got burned. Personally I love the power of this thing but in reality, turn it down to about 2/3 the temperature range and that will be all you'll be able to stand in your tea, coffee, hot co-co. Good Luck! ;-)

These heaters work great, but don't be upset if the heating coils don't last more than a couple of years. Ive had two of them and each failed before they were 24 months old. Both had open (failed heating elements) and no one will sell or make that coil available to the public. Sort of a shame that you'll be replacing a $150 heater for a $10 part that could be easily replaced.Either way, I love to have it in the house. On a side note, This manufacturer makes the identical heater for companies like Frankie who will charge you 3 or 4 times the price. Don't waste you money for the same product which has identical components. I've had them all apart and they are exactly identical. Stick with waste king and be prepared to replace it in a couple years or so.

This is the 3rd hot water tank I have installed and the easiest by far. I also connected this from my 5 filter RO unit with a Hot/Cool water tap that came out just great. Not to the tinkerers out there, it is not a good idea toi try and take this unit apart to look for leaks, if you are careful and able to fix your issue, resembling this unit and securing it with screws may create other issues. I found I still needed to replace this unit and be very careful on the install not to move the unit to much!
