Questions & Answers

How does the RS15 compare to the RS14? Is it okay to use green water in potable ?

RS15 might be a better choice for you The six-stage system for potable water consists of 6 SS Green.

The device can recirculate hot water or ice-cold water. Which one is better? Can I use it in that manner if I wish to?

Cooling is a factor to consider when deciding whether to use a hot water or cold water pump. A common principle is that all hot water pumps can also pump cold water regardless of their In the case of cryogenics, this is not true. This is the summary of what we learned. The answer is yes.

Is there an English version of the instructions / operating manual?

Not at all! Instructions are illustrated in cartoon form. This is not much of a deal.

After a heat pump is installed on the hot water discharge line, how should it be primed?

Until it is primed, the pump won't work. While the supply valve to the water tank was closed, the faucet was open when you installed the pump. You need to re-install the pump after it has been installed Allow the water to flow for a reasonable amount of time until you begin to notice a solid stream of water coming out of the faucet outlet and the gurgling has stopped at the open faucet. After this, let it run this way a little bit more, as trapped air may still escape. You can shut off the faucet and then operate the pump if the faucet is running full water for a long time. I find it hard to believe people would call this self-serving How do you prime?

The pump works great The installation process was easy and went smoothly
5/5

I thought it was a good buy for the money. To circulate hot water throughout the house, we use this pump on our water heater. Hot water is readily available at every faucet, and we love this feature. Easy to install, easy to use We found that when first installed, there was a smell coming from the hot water, but it lasted for about two days, and then it disappeared It was presumably oil in the pump that made its way into the hot water when it was installed and dissipated over time. Great product! I had a pump in my house that cost three times as much as this one and it only lasted Our choice was good, so that's what we did.

This unit is exceptionally quiet and stable, but it requires priming in order to operate properly
4/5

This is the RS15-A we bought In a DIY hot tub, you can use tube 6 (the blue one) to circulate water through an instant hot water heater. In addition to being quiet, reliable, and able to provide 8PSI (about 18 feet of headspace), I also needed something that was durable and cost-effective. The tank we used had a minimum capacity of this amount. Besides that, I would like something that we could put in place and forget about (or let it prime itself, then turn it on as It is equipped with RS15-based features The 6 did an excellent job on all of this, with one caveat, however. Instructions state that it must be properly primed, but it is extremely important. No, this pump does not operate on its own You can't prime it and have air in the lines, so you can't push anything. There are some pumps that are forgiving when the line is partially primed. The RS15-500 does that This is not the case with 6. The pump will not work if the line is full of air. The grade has been reduced by one star. I don't think it's due to the pump itself However, this can cause problems even with a permanent installation if air gets in the line. This was solved by installing a three-way garden hose fitting by hooking up one intake side to the tub, the other to the faucet hook, and the other to the pump output. It makes it possible to prime the pump without any hassles by just turning the faucet on. In the manual, they describe a setup similar to this one. There are times when we have operated the pump for more than 30 minutes at a time (not sure whether it is really rated to do so) and it never overheated. This winter we will see how well it does.

Exactly as described, great pump for a reasonable price
5/5

Purchased this pump for water circulation in a bathroom away from home, it was easy to install and was extremely fast. In addition to this, I can now control whether the pump runs on a schedule. If I want hot water during off hours, I can just command it. I never waste any water by simply asking the Alexa to start the pump. Wait a minute, and I have instant hot.

This works really well
4/5

In order to have instant hot water, I got this to circulate the water from my water heater to the far fixtures in my house. I am very happy with it. The leaks from the connections were a problem for other reviewers who had issues with the pump. my experience in plumbing, I figured I could handle those challenges. The first thing I realized is that the threads on the pipe are not the same as the threads on the hoses, so a straight pipe connection was not viable. My first purchase was an adapter with hose threads, thinking I had already solved the problem. But it wasn't enough. That is incorrect, it leaking badly. It would not stop leaking no matter how many times I tried. Whatever the problem was, the threads on the adapter were weak or the adapter was warped. There is nothing superior about my In order to hook up the water heater, I tried a braided hose. I got it to work! This approach has the disadvantage of not supporting the pump since the hose will not go through the pump. My waste water pump rests on top of the water heater now that I have a long, looped hose that is 24" long and long enough to loop without kinking. After placing it on the water heater I connected it to the water supply again with another braided line. It went smoothly. I used the styrofoam packing to support it and just let it rest on the water heater. My timer is linked to an outlet and is triggered by a light switch. With a cost of less than $30, it also works well. Here is a photo. However, I am considering getting a smart outlet so that I can turn on the pump via an app when I need hot water, as another reviewer suggested.

Using a regular joint compound and pipe and joint compound will result in leaks
5/5

I have no problems with the pump. My cold water heater is attached to the cold water return line and the pump is at the end of the hot water return line. The whole house has instant hot water. We insulated the lines and raised the crawl space temperature by only two degrees thanks to this. The most efficient way to install this is to use 3/4" fittings with a gasket like those used for.

I use this pump with my tankless water heater and it works very well
5/5

I use this pump with my tankless water heater and it works very well. This pump supplies hot water to all my hot water faucets instantly every 15 minutes with the Amazon KMASHI Timer Switch Outlet and Grundfos Comfort Valves. Combined, these systems provide instant hot water to my pipes every 15 minutes and run for 2 minutes each time.

Water can be saved
5/5

We'd need a long time for the water to warm up in our master bathroom and kitchen sink. There is now an instant response. It's not necessary to add a timer to the pump since no timer is supplied by it. The timer does not work when I plug it into a WiFi outlet. The fact that I can turn it on or off from my phone is so convenient when we leave home or before we.

Everything seems to be going smoothly
5/5

We installed it under the sink for instant hot water in the bathroom faucets and shower to instantly heat water. My smart plug lets me control it with Alexa, so I can turn it on and off using the voice. Due to my retirement and lack of a fixed schedule, I did not want to spend the extra money for a unit with a I can also set up a timer through the remote app on the smart plug if I need to do so. I am very satisfied with how it is working.
