## Description

APCOM UT1 Automatic Hot Water Recirculation Pump For Under Sink - Instant Hot Water Recirculating System For Tank Type Water Heaters - Energy & Cost Efficient - desertcart.com

Review: Easy to install and works great! - If it takes your water a long time to get hot, this will solve your problem. I was considering a similar system where the pump mounts at the water heater, but that installation was much more involved and I didn't want to deal with that. Then I found this where the pump mounts under the sink. Installation could not have been easier. You do need an outlet under the sink, or near enough to plug the pump into, and room enough under the sink to put it. I had to mount a small shelf to the back wall of the sink cabinet to get it above the stuff we have under the sink. Make sure you put the brass fitting with the red mark on the hot side of the pump (also marked red). You can get this wrong - ask me how I know. Just follow the installation directions. Our water now gets hot in seconds. You can hear the pump humming, but it doesn't run often and it's small price to pay for having near instant hot water. It was a little on the expensive side, but the quality is excellent and it was well worth the investment.
Review: This pump actually works! - I have a kitchen sink that is quite far from the tank-top water heater located in the garage. It takes up to 2 minutes to get the hot water. Recently I learned about recirculation pump idea. After doing some research and given that I have a power outlet underneath the kitchen sink, I purchased APCOM UT1. The unit is quite heavy, which I'd personally interpret as being well-made. The installation takes like an hour but not difficult. I just need to make sure all connections are carefully tightened to avoid water leak. I also used a smart power socket so I can control the on-time from my phone instead of using the built-in timer. This unit works beautifully. For example, I set my smart socket to turn on between 7am to 9am in the morning. When we get to the kitchen in the morning after 7am, the hot water is available almost instantly (in contrast to 2 minutes wait as before). I'm also very satisfied with the very low noise level when it runs (I have pretty sensitive ears to noises). The built-in timer is also super quiet (even though I don't use the timer, it keeps running when the power is on so the noise level matters). The only 4-star (instead of 5-star) I gave is the price. $350+ feels a bit pricier than I hoped. I went for it for the brand. I definitively don't regret paying for it.

## Questions & Answers

**Q: Does the pump prevent flow when not running? Not just a check valve to prevent back flow, but a complete isolation between the hot/cold lines.**
A: I'm not sure if there's complete isolation, but keep in mind that the pump creates a side-chain to the flow of water from supply to outlet, so when it's not pumping, the natural flow (on both H & C sides) is going to bypass the pump and do very little intermixing, even if there's not perfect isolation.  Hope that helps.

**Q: What size are fittings?**
A: 3/4

**Q: Is this compatible with Ranni  tankless lol water heater**
A: I do not know why it would not work with a tankless water heater, and plan to try this device.  

We have a tankless water heater in our attic, and in winter we will run the downstairs kitchen sink hot tap for literally minutes in order to get all the standing cold water in the pipes to flush down the drain so that the hot water from the attic finally arrives at the kitchen sink tap.

Assuming that this pump comes on every 15 minutes [four times an hour] and runs three or four minutes until the hot water gets to the sink tap and gets the volume of water in the many feet of piping to the kitchen sink replaced with hot water, the next time we actually want hot water, the pipes should hopefully be filled with maybe room-temperature water instead of 40-or-50-degree-F water.  

When we run our dishwasher, the kitchen sink's hot water tap will start getting hot water within 10 seconds if we turn it on within 20 or so minutes after the dishwasher has completed its washing cycle that uses hot water.

Bottom line, when we open the tap after this device is installed and running, we should immediately be getting hopefully at least room-temperature water instead of 40-50degree water, followed by the tankless-heated-water in another few seconds, because when the tankless water heater kicks on the metal copper piping won't need to be heated from perhaps near-freezing.

**Q: Does this work with tanks that have heat traps?**
A: Yes this is a circulating pump to get hot water to the valves without having to run water down the drains
