Thanks for sharing your video. I have done something very similar but incorporated the pump into our Alexa "Good Night" routine which turns the pump on when we head to bed and shuts it off after 10 minutes. Works like a charm and gives my wife instant hot water in our ensuite bathroom which is the furthest water faucet from the hot water tank.

We have Alexa, but no smart switches (yet). However, the Watts recirc unit comes with a valve that you can install under a bathroom sink farthest from the hot water tank. When the hot water from the pump hits it, the valve closes, keeping the cold water cold without a separate return line. We have our timer turning on the pump every 15 minutes in the morning, then every 30 minutes during the day as we're usually both home. Then once every hour after 5pm and off after 10pm. The hot water comes out warm right away and we're not wasting any water. There is also a selector for constant on or off, too, so you can turn it off while you're away on vacation without losing your settings or TofDay. Best addition to our new HW heater and I wish I had installed one years ago! I considered a "switch" but the valve and very flexible timer cinched it.

Nice video. Assuming the line size to all your fixtures is 1/2", any reason you went with 3/4" for the return (that's the size of the pump)? To me, that's just more cool water in the line that needs to be flushed. If the water heater has 3/4" connections, I guess that could be one reason to go with 3/4".

Thanks for the video. I've a few questions. It looks like you installed the pump on a T on the cold line entering the top of the water heater? Was the check valve right after the pump before the T? I already have a thermal expansion tank on my water heater. Will the recirculation pump play well with the expansion tank? Where should the pump and valve be in relation to the tank?

I use motion sensors instead of relying on a switch. Making it totally automatic. I have sensors in the master bath, kitchen and outside a guest bathroom. So, I don’t have to even think about pressing a button or turning on a switch or a light(i seldom turn on the light in the master bath during the day.). Which has worked great.

What kinds of sensors. I would like to get this set up

+1 on wanting info on your sensor. Agree, much nicer than a manual switch. Even using the light switch, at night there would be times when that's not turned on, but then you still want to use the sink.

Hi, the pump circulates through the crossover valve. What if for some reason, the crossover valve being blocked, will the system be over pressured? I don’t see anyone install a hammer arrestor or a relief valve. Thank you!

This is a great idea and hooking it into your smart home is a great way to do it. I wish I could do this as well but we have a tankless water heater so it won't work unless I put a hot water tank somewhere in the system. I wish it would though because tankless heaters have an even longer run time before you get hot water and it's a major pet peeve of mine.

From my research you can do this with a tankless! You should look into it!
