Which would be better, this or just a local under the sink small water heater in the bathroom. I'm trying to save water. It takes a good 2 mins of running water to get any hot water.

This one is the better choice. The pump and the sensor bar are Grundfos the best pump on the market. I have seen Grundfos pumps go over 30 years in our plumbing business. The sensor bar should have a life span of 5-10 years and the replacement is usually $80.

Well, As a Do It Yorselfer, or more appropriately do it for the wife as she dieects the project while watching the video, she said she kinda LIKES the Verb "Unloosen" !! Maybe you have knowledge of what the heck is in the middle of that valve that is the sensor for the water temperature cut off?

[@DIYOnTheHouse]

It's a thermostatic valve.

This video was great It even made a non-DIY guy like me think that I could actually install it myself. One question I have is regarding the under sink sensor bar. According to another video I saw, I thought you only need to install one of those sensors under the sink furthest away from the water heater. But in this video you installed multiple sensors at different sinks? Trying to understand if one is enough, or if I need one at every sink?

[@DIYOnTheHouse]

Most houses will have a manifold near the water heater and that will send water different directions. What you can do is turn on the furthest faucet until the water becomes hot and then check faucets between that and the water heater. If the water heats up right away then you don't need another sensor. If it takes a while and you don't think it's satisfactory, then you can install another sensor at that point. You kind of have to decide is the cost of additional sensors and time it takes to get the hot water worth it.

@@DIYOnTheHouse Excellent answer. Thanks.

Will this pump bring hot water to faucets that have a long wait time for hot water to run? Am I understanding this correctly. I have two sinks like that. One is the kitchen sink, one is a bathroom sink. I had thought to put an on demand unit under my kitchen sink, but if this would do both sinks I will check this out. Thanks.

[@DIYOnTheHouse]

Yes, it will. You will need a sensor bar under each sink. Here is the sensor link amzn.to/49jQsGV -- pump amzn.to/4cMMjhI. Feel free to email me if you have any more questions [e-mail]

What about summertime scorching hot cold-water line?? Will this work for the cold side as well??? Using the supplied thermal shut off valve??

[@DIYOnTheHouse]

It is not designed to go on the cold side nipple. If temperature is a issue in the summer months you can turn the thermostat down on the heater.

@@DIYOnTheHouse so I have one of these in a house we just purchased and like the comment above, the sink where this "valve" is installed is only giving hot water on the cold water side, we never get cold water although we have it everywhere else through the house, so is it possible that this "valve" is bad??

Can I use this Pump for dedicated return line system?

[@DIYOnTheHouse]

Yes it will work great.

My house is a 1300 sq ft. 1971 ranch. Water heater in the laundry room at one end of the house, showers clear at the other end of the house. To get any hot water in my shower I have to turn it on and let it run while I brush my teeth for 2 solid minutes - or more (my teeth are very well maintained!). That's a lot of water just going down the drain just to get hot water. Is there something like this I can use for my shower?

[@DIYOnTheHouse]

You can use this watts system if there is a bathroom vanity in the room with the shower. It will take the 2 minutes down to 15-20 seconds.

[@MrTennc]

The pump overcomes the cold water pressure which means the lines are seeing increased pressure. Blowing open a plastic joint is a disaster. So how much more pressure is put on the piping by the booster pump? Is there a relief mechanism to prevent overpressure?

[@DIYOnTheHouse]

Circulating pumps don't increase the pressure on the system, they just move the water. This pump has an open cavity that doesn't allow them to pressurize anything. Circulating pumps are not booster pumps.

[@kevinwonsetler3777]

I dont understand the timer? Shouldn't it be recirculating all the time?

[@robertingram2820]

Thank you Sir. Appreciate you speaking loudly and clearly with no funky music in background...

[@rusteeznutz]

As a plumber i do not condone the use of the word unloosen.
