Rated 5.0 out of 5.0 by DIYER Great idea
This pump does everthing it says it does. Easy installation. Over time I expect to save water and sewer charges. This is such a simple idea. The pump has a 24 hour timer. I set the timer to run all the time and control the receptacle that the pump is plugged into with a timer so I can turn the heater on when I need too. All of these parts came from Home Depot.

Rated 4.0 out of 5.0 by jeff Easy to install - Provides instant 95 degree water - then hot within 10 seconds
Easy to install. The unit does not come with water lines so you need to purchase 3/8 to 1/4 compression. You remove the water lines to the sink -then hook them to the pump top. Then attach the new lines to the house water and pump. Easy to install. Plug the pump in and you get 95 degree water. Then when you turn on the faucet- 10 seconds later you get hot water. I insulated the hot water line in the basement. The water lines are PEX so they do not retain heat like copper. So we went from running the hot water for 90 seconds to 10 seconds. The water is 95 degrees on the hot side and cold side since the water is being mixed. In 10 Seconds you can get the cold water to run cold and the hot water also. So we are saving 80 seconds of wasting expensive water. I see no difference in how the water heater runs. I will update once I get my next water / gas bill in 30 days.

Rated 5.0 out of 5.0 by John Less water waste
I installed this under a pedestal sink so there is no cabinet to absorb the noise but the pump is still reasonably quiet (less than a quiet bathroom fan).
I added a receptacle into the lighting circuit so the fan only runs when the light is on. Once you turn the light switch on it takes about a minute for hot water to reach the pump (which is about how long you'd need to run the faucet to get hot water without the pump).
Easy to install but be sure to order two faucet supply lines when you're ordering the pump. Your existing supply lines from the shutoff valves to the sink will get connected from the valves to the pump, then you'll need two more 3/8 X 1/2 lines to connect the pump to the faucet.

Rated 5.0 out of 5.0 by Homeowner The Autocirc turned out to be a good choice to get instant hot water
I spent several months researching the best solution to get instant hot water to a
bathroom that is quite a ways from the water heater.
The Autocirc instant hot water pump turned out to be a good solution.
I have had it about 6 months and it works well. And it was easy to install and less expensive than
some other solutions.
The installation was easy as I have an electrical plug that was close by.
The water hookup was easy, just 4 flex hose connections.
The pump is not noisy. It does make a hum when it is running but I can't hear it except when I
am in the bathroom. And to me it is not any louder than a refrigerator or the HVAC.
It has a timer and I have it set to run in the morning and evening and even when it is on
it does not seem to run very long at a time.
I tried to notice if I could tell any difference in my gas bill because of the water heater running
more but it did not make a noticeable difference.
It does make the water at the sink hot quickly and at a close by shower within a few moments.
Another thing I noticed is before installing the Autocirc if I shut the hot water off for a short time
it would quickly cool down, which was annoying. The Autocirc solved that problem.
This is not really a complaint but the water only gets warm not hot, I wish the hi temp were set a little hotter, say 5 degrees or so.
This is not a problem for me but be aware the cold water at the sink does get warm until you run it a few seconds.

Rated 4.0 out of 5.0 by Brandan Overall, this product works as it is described.
I installed the pump under our kitchen sink, as this is the furthest water faucet from our water heater. I set the timer to operate between 6 AM and 10 PM, and during those times, we have warm or hot water available within seconds. Way better than before...which could take up to 90 seconds to flush cold water from the pipes.
There are some noises (gurgling and squeaking) as the pump starts and starts, like shutting off a ball valve, and only minor noise when the pump is circulating. With the cabinets closed, the noise is tolerable.
Overall, a good purchase and when compared to other, more elaborate pumps, very cost effective.

Rated 5.0 out of 5.0 by taupe56 Worth its weight in gold
I have used this pump for over 10 years and never had a problem with it. My water inlet from the street is at least 50 feet from my second bath room and shower and I never have to wait for the hot water in the bathroom sink. The shower takes a little bit longer because of the length of the pipes. All of the other sinks in the house have instant hot water. This pump has probably saved me thousands of gallons of water over the years since I installed it. I might add that in my town we have strict water conservation rules.

Rated 5.0 out of 5.0 by Robert99 Hot Water When You Need It
This unit provides Hot Water when and where you need it. Installation is quite easy and the almost instant hot water can be very convenient. Now, that's about where it ends. If you're looking to be environmentally savvy by saving water, this isn't going to make much of a dent. All that you are buying is CONVENIENCE. That being said, is it worth the investment? Investing in this is like when I purchased the “Remote Start” feature for my car. Does it save me money or wear and tear on the car? No, but I would invest in this feature again? ...in a heartbeat!
Do yourself a favor and Google "Do hot water recirculators save money?". There is a very good, accurate article in tree-hugger that explains in detail using very generous and conservative numbers how to calculate the savings …or non-savings. One article uses a water savings of 2.8 gallons per draw with a ¾”dia. hot water line over a 50 foot distance. In actuality, I have a ½”dia. hot water line and calculate a half gallon savings. In reality, before the recirculator, I run a half gallon to warm water and about ¾ gallon to hot on my 50 foot distance. You’ll have to read it for yourself if you want to consider heat loss and energy use even if pipes are insulated as well as electricity use. If you're looking to save money, there's a negative return on investment (ROI) by installing a recirculator. Because there is no financial payback, the unit never pays for itself.
But remember, what you are buying here is convenience …and at the end of the day, that just might be what you want.

Rated 4.0 out of 5.0 by BobTheLobster Pricey Bang for the Buck
Product works as advertised, but at an exceptionally high price! The install was straight forward and no more difficult than installing new faucet hoses. We had hot water within minutes of install and start-up at our kitchen sink. Also, delighted that there is now instant hot water for the dishwasher so it can do its job properly. Other benefit is that the laundry room now has instant hot water, so the "warm" and "hot" water wash options on the washer really do what they're supposed to do. No reason this product should cost more than $60, but the market seems to be cornered by few suppliers. HomeDepot was the lowest cost (least of all evils) on this one. So, if you want instant hot water, this is the way to go. I prefer this product to the "two-part" one that I mounted where the pump installs at the hot water heater and the thermostat-valve at the sink. (I have two hot water tanks and separate hot water systems.)
