Hot water in a flash.
Installs easily and works great. The 3/8 to 1/2 adapter was installed already so it appeared as if the hose was 1/2 to 1/2 , but all that you have to do is remove the end with the adapter.

Cheaply make. Not happy at all.
Cheaply make. If I could give it no star, I would. I bought two of these. I had to throw away all hoses because they all leaked no matter what I did. Not only it cost more money but also I lost a lot of time and to make two trips to home depot to get new hoses. Not happy at all.

Sensor Valve - Hot Water Circ Pump Companion
As advertised. Along with my Grundfos hot water Circ pump, we have hot water almost instantaneously at kitchen sink and master bath, which are farthest points in house from hot water heater. I have one installed at kitchen sink and one installed at master bath sink.

Hot water on tap.
I had installed a Watts recirculating pump in my new townhouse. Due to the plumbing run, I had a branch line and I needed a second check valve kit. After installing the second kit all is good. I have hot water with in 10 sec. The check valve kit comes with all the needed parts and hardware.

Design flaw of the product
The product has a design flaw. It works, allowing hot water to bypass and go to the cold water pipe as it is supposed to. When the temperature increases, the bypass shuts down. However, at a regular temperature, it also allows cold water to bypass going to the hot water when the pressure on the hot water side decreases. The problem is that there is no temperature increase if cold water flows to hot water pipe. In this case, you will not get hot water at all because cold water will keep flowing to the hot water side. The product should have a stop valve preventing cold water flow to the hot water side.
