I'm looking at their website.....what am I missing? Seems the same Watts/Grundfos bridge valve is used in all applications...maybe with enlarged shut-off valves or flex lines, that give more flow....but not a different bridge valve. No ?
@@TheWilferch You need to contact them directly about their Brass Bridge Valve. It is part of their professional systems which they do not sell online. 619-665-2077
It's funny that they created the video but don't know how to answer! I am a DIY person. In physics, if you have this valve on without the pump, the hot water actually pass the valve a little bit because the high pressure while it is hot. But, it definitely will not flow too far from the valve. Creating a warm water line without having a circulation pump on the line is impossible. Therefore, you will end up to pay more money on the gas bill due to the temperature drop in the tank and it will keep the gas stove running all the time. To install this thermal bypass valve, you will end up of installing the pump and modifying with a timer so that the pump will turn on and off in a certain time!
Bud, do some research! This thermal bypass valve is a hoax. You will waste your money and time for nothing. What this valve does is to allow the hot water line from the heater water tank pass through the valve only one direction. Once you turn off the hot water faucet, this hot water line will be pushed back through the thermal bypass valve to the cold water line back into the heater tank. This is how you will get the hot water current remains in the line until you set the timer to make it to be timed out. Therefore, in order for this valve to be working correctly, you need to have a recirculation pump to be installed at the heater output. This recirculation pump will circulate hot water through the cold line back into the heater and exit to the hot water line again. To have this system works correctly, you need to set the timer on that circulation pump and adjust the heater to medium or it may get too hot on the line. Without the timer, the pump will keep pumping and you will end up paying more for gas bill or electric bill depend on gas heater or electric heater. This thermal bypass valve installation in this video is missing. For me, it is too complicated to install. The very best to deal with this is to install a portable heater under the sink. Those portable heaters are cheap and they are easy to be installed!
@@Robie1 I have a recirculation pump on the hot water heater downstairs, the recirculating line like this upstairs under my for the sink. I turned off the recirculating pump, and I unplugged the timer. I am still getting hot water almost on demand upstairs in that bathroom and I don’t want it recirculating because I just found out how bad my copper pipes are. Why is it still coming up there so quickly if the pump is unplugged and what pipe is it recirculating through? The cold pipes? Would it help if I had someone remove the thing under the sink upstairs?
@@jeanies8495 Yes. If you are still getting hot water on demand without the pump on the comfort valve may be stuck in the open position. You can try to close the isolation valves for a few moments. This may reset the comfort valve. Or you can simply remove the comfort valve. Best of luck,
@@jeanies8495 That is odd regardless of the mixing valve being open or closed. Something is heating the water inside the copper pipe between the sink and the water heater. Does any of the faucets sometimes turns on by itself?
