Easy to install . As i had one in place that needed to be replaced. Works fine.

Dispenser was bought to replace identical unit that had failed after about 5-6 years of daily/loyal service. The unit retains its solid build, however the instructions leave a lot to be desired. Confusing, & poorly diagrammed, combined with parts that have no use keeps this from a 5 star review. Plumbing knowledge is essential for a successful install.

Bought this Waste King H711-U-SN to replace an Insinkerator hot water dispenser I've had in my home for 15+ years. I actually installed one of these for my parents at their cottage a few years back and don’t remember them complaining about it. The Insinkerator still worked flawless but I was in the process of changing out the sink so why not have a hot water dispenser with a more decorative faucet matching the kitchen faucet. Right? If you price an Insinkerator system with decorative faucet they get pretty pricy.Received the unit March 7, 2018, installed March 9, 2018. Installation was fairly straight forward. Other than the tight work space, I had it installed within about 2 hours. First thing I noted was the eratic spray coming out of the nozzle as I purged the tank and lines. Pulled the nozzle off to find the o-ring bunched up and partially blocking the outlet. O-ring was destroyed so I removed it.Next observation, it would spit & spew water every time it heat cycled. Had to turn the unit down to just under 2/3 on the temp dial to rectify that situation. Water temp right around 140-145º. HUH?!? That’s a FAR cry from the 190º they advertise and even farther than that of the +200º from the Insinkerator unit. There goes making instant oatmeal, ramen noodles, tea, HOT coffee, etc… Seriously?!? Starting to miss the point of this purchase. But OK, it was half the price of a comparable name brand unit (trying to justify the purchase)… ugh.So this bring me now to Saturday, March 17th, St. Pats day. Woke up to the dispenser dripping, drop or two every 2-3 seconds. Actuated the valve several times to clear any possible obstructions. Nope, still dripping. Cut the temperature down even further. Still dripping... Through Saturday & Sunday I attempted various fixes, nothing resolved the issue. Contacted customer service this morning. Explained the new install and that in under two weeks the faucet is now constantly leaking. First excuse, it’s my water supply, i.e. dirty or contaminated. “Well ma’am, I run reverse osmosis through this dispenser and my fridge ice/water dispenser. I’ve had the system installed for roughly 15 years. While it’s certainly possible I would tend to believe something failed in the faucet.” Second excuse, my water pressure is too high. Cut the water pressure to the dispenser. “Why would I need to or want to do that?”, I inquired. “Our system is designed for lower pressures.” I comment, “You mean your faucet is not designed to handle typical municipal code water pressures?” No answer. So finally after screwing around with ridiculous questions and blaming game I got to the point, I requested service parts for the faucet. “The faucet is not serviceable.” “No service parts are available for the faucet.” WHAT?!? YOU'RE KIDDING!That’s it. Game over. Pulling the dispenser unit out this evening and sending it back (What a PITA). I know what I’ll be purchasing now, hint it won’t be a Waste King. Decorative Insinkerator faucet (only) for a few dollars more on Amazon. Done, order up.This is truly one of those, you get what you pay for. I wanted to save some hard earned cash and now I’ll pay extra in my labor to remove this substandard dispenser. Moments ago I was telling my father the above story and he commented they shut their unit down after about a year because it was doing the same thing (leaking faucet). I’m like, “Dad if you would have told me we probably could have gotten it covered under warranty…” Anyway, buyer beware. Best of luck.Pros: Looks nice.Cons: Reliability, NO service parts, questionable customer service, did I mention it’s NOT SERVICEABLE, NO SERVICE PARTS. Replacement faucet costs more than the entire system (heater, faucet, installation kit).

a little challenging to in stall, but works great

How to fix the Waste King H711 Dripping FaucetI have been using hot water dispensers for 25 years. I went through so many InSinkErator brand “Hot Taps” that I lost count. They would last 2 or 3 years and fail.In 2009 I decided to try the Waste King H711-U and it lasted an incredible 5 years and 3 months.I also liked it better that the InSinkErator “Hot Taps”. It had a larger capacity tank, better flow rate and a better faucet. Several of the copper tanks in the old InSinkErator models had failed, so the stainless steel tank in the Waster King sounded like a good idea.When the heater coil in my H711 corroded and burned out after 5 years I bought a second one without hesitation. I have had more issues with the second unit. At a year of age the tank stopped reaching full temperature. Customer support worked with me and with some effort I could get it to 180 degrees when set at max. They replaced the tank free of charge!Unfortunately, the faucet started dripping occasionally just after 1 year of age. It would drip for a few days and then stop for a few weeks. However at about 17 months of use, it became a fast steady dripping and needed to be fixed. This seems to be a top cause of negative reviews here.I asked Waste King customer support if this valve could be serviced, perhaps a washer or o-ring could be replaced. They were nice but said it was sealed and could not be serviced. They said it had to be replaced. They also acknowledged the odd fact that most suppliers sold just the replacement faucet assembly for more money than the entire H711-U installation including the tank, fittings and faucet. As of this writing, Amazon charges just one dollar less for the faucet than the whole kit. Better to buy the whole thing and have a spare tank if you need it.So, I was faced with replacing the whole unit. With nothing to lose, I decided to attempt repair. I was successful and it may be a very easy repair or a moderately difficult repair depending on your situation. Mine was the latter. Here is what fixed my HL711-U faucet:First, you need to be reasonably comfortable with plumbing and hand tools. You don’t want to flood your kitchen with near-boiling water.Step 1: Before working on this appliance, please unplug it and wait for it to cool down or run the water until it is cool.Step 2: Turn off the water supply to the H711. If the water is on, you will make a fountain in your kitchen when you open the valve. If you didn’t do step 1, you will make a fountain of near boiling water.Step 3: Repair the leak.I had to fully tear down the faucet and so I uninstalled it before taking it apart. To remove the faucet, you have to disconnect the two water lines from the tank and remove the nut under the sink that holds the faucet to the sink deck.If you are very lucky, you may be able to fix the faucet QUICKLY without even removing it.The first picture is of the valve mounted on a sink. There is a nut that holds the valve parts together. You can remove this with a 3/4” crescent wrench or an adjustable wrench. There is a white plastic plunger under the valve lever. It has a strong spring below it and you should be careful when you remove the nut and faucet lever. My valve was stuck and did not fly apart when I disassembled it.Note the angle of the faucet lever and the position of the slotted metal collar below it so that you can return the lever to its original orientation. (When you re-assemble the faucet, you can actually rotate these two pieces to make the faucet lever work sideways if you prefer.)If you look at the second picture you will see what is below the faucet lever. The white plastic plunger has two 1/4" o-rings. In my case, the bottom o-ring was damaged and causing the leak.If the plunger comes out and you see that the o-ring is damaged (or now missing) replacing this o-ring will stop the leak. This is a standard 1/4"x1/8”x1/16” faucet o-ring available at any hardware or big-box DIY store. (See the third picture, I bought mine at Lowes for $0.50)In my case the o-ring had become jammed in the bottom of the valve and the white plastic plunger could not be removed. This required some significant extra effort to fix. This is where it became apparent that the customer service people were telling the truth. If the plunger does not pop out, then you have to disassemble the whole valve.To remove the whole valve core shown in the picture, you need a 17/32” socket that will fit into the hole that you have opened in the top of the faucet. 17/32” is an odd size and is not in many socket sets. The only 17/32” socket I had was slightly too large to fit in the hole. I had to use a bench grinder to grind it down a bit to fit. This is the hard step and if you can’t get a wrench or socket down that hole you are finished.You will have to remove a slotted metal cylinder (not shown) that is just sitting in the hole. This is the slotted piece that the faucet lever rests in and which determines its orientation.At the bottom of the hole you will see the nut (marked on the second photo). Once I reached that nut at the bottom of the hole with a socket, it came out easily. I then had the whole assembly as shown in the picture.Clean out the damaged o-ring bits, replace the o-ring and re-assembled the valve.When re-assembling, the two larger o-rings rest on the smooth areas marked in the picture.The repaired plunger with two good o-rings easily slid into place but had to be held down against the spring until the nut holding the lever down was replaced.It has now worked perfectly for over a month dispensing at over 190 degrees.---------------------------------------------------------------------December 2017 UpdateThe repair lasted less than 8 months before the dripping began again.Since I had the disassembly process all figured out and I had the tools, it took only about 1 minute to get the valve apart and see the problem. The same o-ring was again bulging out and causing the leak.Though I could easily see the problem, the O-ring proved quite difficult to remove. The original O-ring easily came out in pieces. The replacement O-ring that I bought in a local big-box store was a LOT more sturdy and could not easily be ripped out in pieces. The trick that finally worked was to use a sharp pin.Puncture the O-ring with the pin and then compress the spring. Pry the O-Ring out slightly and release the spring. The O-ring will now be pinched slightly further out of the groove. Repeat 3 or 4 times and work the o-ring further out of the groove in the plunger. You can then pull out the O-ring with a pair of tweezers while compressing the spring.1. Unplug hot water dispenser and allow to fully cool.2. Turn off water supply and observe that dripping stops.3. Use a 3/4” crescent wrench or an adjustable wrench to remove the nut under the faucet lever.4. Remove the slotted collar with tweezers or fine needle-nose pliers.5. Use the 17/32” socket to remove the whole valve core6. If the valve doesn’t come apart, you will have to depress the white plunger to compress the spring while working to remove the o-ring. (I did this by pressing the assembly down onto a hex-nut that was smaller than the plunger.) Once the o-ring is removed, the assembly slides apart and a new o-ring can be easily installed.It was suggested that a “Viton” o-ring might last longer and reduce the frequency of repairs.I will try that if another repair is needed and post an update.

We love it. It was not as easy to install and had to hire a plumber but it works wonderfully.We had a Kitchen Aid previously that was triple the cost. We were worried this would not work well at this lower price. It Has! We had also previously tried 4 different Instahot but they all burnt out in less than 1 year. We Won't go back to that brand. The plastic handles also broke off. This has a good lever. The temperature control is vast. We need hot water but you can adjust to a very wide spectrum. Quiet and excellent so far. We did take a cold line and ran it through our 2 stage water filter and then split the clean cold water line. We ran one of the cold filtered lines to a dedicated cold drinking tap and the other filtered line we ran into the Waste King. Perfect taste and temperature. We hope it lasts. It also has a good holding tank.

Defected Product. Bought it back in early Oct. Installed the unit just today and found out that it is defected. Water is leaking from the base of the dispenser. $283 down the drain.
