Review: Highly recommended - You need this pump to get hot water quickly from your water heater to your faucets and showers. It also improves the performance of your laundry machine and dishwasher. I puchased a new home and it literally took 5 minutes of running the water for it to produce hot water. I have a friend who is a plumbing engineer and he recommended this. I installed two valves; one under my kitchen sink and one under the faucet furthest away from the water heater. This resolved the issue and I now get hot water quickly to all of my faucets and showers. The Grundfos pump is excellent quality and very solidly built. The pump gets hot during normal operation, but will run for many years (I had one installed in a previous home and it is still running after 8 years). I like the timer function so that I don't have to run it in the middle of the night while everyone is asleep. One thing to note. You need an electrical outlet close to the water heater to plug the pump in to. My garage did not have one close, so I had to have one installed. I hate plumbing, so I hired a plumber to install the pump. Money well spent, IMHO. Also, unless you have a dedicated return line, the pump cycles water through the cold-water line. This makes the cold water line luke-warm. I have an RO system and ice, so getting cold water from the tap is not a concern to me. I highly recommend this pump. It should pay for itself over time since less water is wasted. I think that every home should have one of these.
Review: Great design and solid functionality - When I was looking at all the reviews of these hot water pump systems, this Grundfos system seemed to get the best reviews on desertcart and other web pages. It's a bit more expensive than the Watts pump system (also made by Grundfos) but it's also made from better materials. There is no label on the pump itself indicating where it's made, but the box states that it's assembled in the U.S., so that's a good thing! The quality of this pump is immediately apparent when you take it out of the box. It's heavy, very solid and it just really appears well made. My sensor valve is located in my front bathroom because it's the furthest from the hot water heater. Almost instant hot water at that spigot. Before, I had to wait at least 45 seconds to get hot water in the master bath sink (located between the pump and the front bathroom sink), but now it's less than 10 seconds, and really hot water in about 15-20 seconds. The master shower used to be that you had to run the hot water for at least a minute and a half to get hot enough water for a shower, but now I have warm water after about 10 seconds and "shower hot" water in 25 seconds. A vast improvement!! My installation under the sink was relatively easy, the only difficult part was that my shutoff valves are Accor FlowTite valves with the outlet hose permanently attached at the valve end. This wasn't a no-go, but it made getting the sensor valve in a bit more difficult than it needed to be. The included connection hoses and adapters were all I needed for a good DYI installation using a set of pliers as the only needed tool. The pump installation was much more difficult; not because of the pump, but because of the location of my water heater and the copper "flex" pipe attached to it. Unfortunately, the flex pipe is soldered in on the house side and it made it very difficult to get bent correctly to make the pump fit. Trying to get it to not kink was a major challenge, using two channel lock wrenches. Several reviewers mentioned that either the pump or the under-sink valve made noise, but I find it almost impossible to hear this thing when it's running. Also, the box and the instructions say that the cord is 6' long, but although I didn't measure it, it seems to be much longer than that. I had more than enough length to reach the only nearby outlet that's on the next wall over. Some reviewers also state that the pump gets hot, but I've only noticed that it gets as hot as the water passing through it. I don't think the pump motor is over heating. The timer functions OK, but because my installation makes it so difficult to get to, I opted for a Kasa WiFi outlet and app to control it. This works really well, and I can access the pump from anywhere in my house. I would buy one of these again, but if I have any problems with it, I will update this review. With the way it's working now, I don't expect any issues.

## Questions & Answers

**Q: Any reason this unit wouldnt be compatible with a Navien tankless propane water heater in my garage ?**
A: This pump probably will not work with navien tankless.  The navien needs to have a .5 gallon per minute to turn heater on, the flow rate will probably be too low.  Check your model, navien does make a tankless that has recirculating pump installed.  They also have their own thermonic tees that you can install if you don’t have a hot water recirculating line.

**Q: how to get operating instructions**
A: Operating instructions come with the Grundfo's 595916.

**Q: Does this have a button that can be pressed to turn the pump on and cycle the water?**
A: There is a switch as a part of the timeclock that can turn the pump to On. Auto, or Off.  Then look at the perimeter of the timeclock at the little switches, I think there are four per hour. If you push them toward the center the pump will not run at that time; the pump will run during the times when the switches are in the position farther away from the center.

**Q: Plumber said we needed additional parts under kitchen sink and bathroom.  Correct?**
A: Additional hoses to couple the bypass device at the farthest sink connection. Of course the pump is located at the hot water heater.

### ⭐⭐⭐⭐⭐ Works very well, easy to install, silent operation.
*by J***S on January 3, 2025*

My previous house had a dedicated copper return pipe for the master bath, so there was instant hot water and no wasting of water for the shower or sink to warm up. This device doesn't require any special plumbing installs in about 30 minutes with a crescent wrench. Under the farthest sink, you install the supplied temperature sensitive flow through adapter and you're done. There is a slight quirk where the the cold water is slightly warm for a few seconds, not a big deal. After some use I decided to use the timer function (easy) where it cycles on/off every 15 minutes, and not running it at all at night. This gives you warm water in the daytime while using less energy (electric for the pump and natural gas on the water heater) as you're not heating pipes at when not in use. You can buy additional under sink adapters for about $60 so you have instant hot water in both the kitchen and bath(s).
