Waste King Anaheim AH-1300 Quick and Hot Instant Hot Water Tank

My last Waste King Kitchen Water Dispenser was over 13 years old before I had to replace it with a new one. My new Waste King hot water dispenser was delivered the day after it was ordered, it was easy to install and works great.

Installed this as a replacement for the same unit with a Waterstone label on it - this one was 1/4 of the price. For the most part, very simple installation. Only thing to be aware of is that they do not give you a connector for the front peg. This drove me a bit batty because the instructions don't tell you to supply your own connector. I bought a 3/8 to 5/16 push connector (my tubing to the faucet was 5/16) - bought this on Amazon...it worked perfectly. Other caveat, adjusting the temperature just right takes some time. Max is too hot and the water boils. Min is a bit too low (around 140). Mine is about 3/4 between min and max and temp is around 175, which for some people, might be too hot. It's been a month or so - unit is super quiet and has been working well. I hope I'm not jinxing myself by writing this review.

This unit replaced one that lasted ten years and after about a month is working fine. As a mechanical engineer I always try to figure out why something stops working. When I opened up my previous unit, which seems to be identical to the new one, I expected to see a rusted out tank or some other obvious failure, but I didn't. I will examine it more closely some time and keep it for spare parts. I suspect that the leak was nothing more than a loose fitting or bad o-ring. To decide which unit, of the many on the market, to buy to replace the old one I did a lot of research and came up with some conclusions. I can't say for sure if these are 100% correct but I think they are worth sharing: As near as I can tell there are many of these under sink hot water heaters on the market that all look identical except for the label on the front. However the prices vary by almost a factor of two from about $150 to around $300. Some of the more expensive ones have a stainless steel outer shell and claim to have a stainless steel water tank. The former adds nothing of value to the unit since the outer shell would never cause a leak, and in fact has drain holes in the bottom. The latter does have value but I'm pretty sure all the units have a stainless steel water tank, regardless of price. So why the spread in costs? It appears to be due to different warranty periods. The one that I am reviewing, which is the cheapest one I found, has a one year warranty. The highest priced ones have a longer one, typically three years. Based on my research these seem to fail in one of two ways: very quickly, indicating a likely manufacturing defect, or after from four to ten years (or maybe more depending on water chemistry or amount of use). Both warranties cover the first failure mode and neither covers the second. My advice is to get the cheapest one that that has some sort of warranty (like the one I am reviewing). One more thing. A lot of people have commented on the tank leaking and destroying the wood cabinet. I put a plastic pail under the tank to catch the water. Note that even a perfect tank might leak if the thermostat is set too high and the leak is often a small shot of water to relieve the pressure. (November 2020): I have now had this unit in operation for several years and it continues to operate perfectly. I am constantly appalled by the cheap, poorly made stuff that's for sale but this unit is not one of them. It appears their business model is to sell a reasonably priced appliance that will have a reputation for quality and rely on reviews and word of mouth to sell a lot of them-what a refreshing approach! Please be assured that I have no financial interest in this product.

I have an Insinkerator hot/cold system with filtration. I've replaced the water dispenser once and the tank twice using original products. The Insinkerator products seem to have a knack for breaking down just as the warranty expires and Insinkerator won't even consider a courtesy replacement (my second tank started leaking 1 month after the warranty expired). This time I decided to take a chance and replace my leaking tank with this one. This tank isn't as sleek looking as the Insinkerator and is a bit deeper, but it appears well constructed. Actually it may be better constructed as the water in/out nozzles are metal as opposed to the plastic ones on the Insinkerator. Installation was relatively easy as the hoses are the same size; it took me about 15 minutes including repositioning the new tank. All required fittings were supplied with the exception of a metal clamp and an extra foot of water intake line. These cost me a total $1.21 at Rona. I've had it in for four days now and it is working fine. Actually, without the vent hose attached, the hot water does not sputter anymore, so in one way it's working better The only minor complaint I have is that the temperature adjustment is not as easy to use as the Insinkerator tanks. Update: I've been the using the system for about 3 months now and it actually performs better than the original. I not longer get the drip and sputtering I used to get and the recovery time of tank seems to be faster when compared to my original Insinkerator.

Not sure about all the other reviews. The first system lasted over 10 years so let's see how long this lasts. Started to leak for some reason? Install was pretty straight forward as I had everything ready to go. I will say the first time a lot of parts included. This time around very little. You need to be handy, as the instructions are not straightforward as advertised. The tap is NOT included and you need the right tap for this system. Taps range, but their not cheap. Thankfully I had it from the original system (included). It does leak from the tap once I go full TEMP. Altitude is the issue not the system. I just turned it back a degree/two and no more drips. I love this system and once you don't have it you quickly realize how often you use it. Two weeks to deliver as it comes from USA. Much cheaper in USA vs Canada too.
