Nomal for this system. I forget how I found it but on theb site it has a nice manual describing the function. You may want to consider using the time clock function and turn the pump off at night. Unless you need hot water at night at least early in the AM you would get cold water.

Yes. this is normal. Because you are pushing the water from the hot water side to the cold water side. The valve will stop the flow of water from the hot to cold water side at a certain threshold temperature. And this temperature is somewhere on the warm side. Therefore the cold water side will be warmer than expected and you will have to run the cold water side until you get the water to the cooler temperature that you want. This is one of the drawbacks of this type of system. It cannot be helped. It's basically a compromise based on the need to get hot water faster. The only way you will truly get the instant hot water and cold water is to set up your plumbing system whereby the entire hot water supply line daisy chains all your fixtures such that the last fixture has a hot water return line running all the way back to the water heater. But this will cost you money to have a plumber do that. This hot water recirculating system is a compromise to save costs.

I have the same symptoms. The best thing is to run the pump ON and OFF on the timer. ON for the period hot water is needed, and OFF when not needed - when you sleep at night.

I had an old one that I replaced due to getting hot water on cold side that lasted about about 15 seconds -there should only be a few seconds of hot coming out of the cold side so if it take more time there may be something wrong with the unit - mine is fine now. good luck- Steve

The comfort valve under your sink, which connects the hot and cold water lines, is not working correctly and needs to be replaced. That valve should automatically close when it senses that the water temperature from the hot water side reaches approximately 90 degrees or more. Your valve is failing to close allowing hot water to flow to the cold water side continuously. Sometimes, even a new comfort valve can be bad. I had this same problem. Replacing the comfort valve solved the problem.

I installed one of these valves on my kitchen sink without a pump (as mentioned by an engineer in one of the online reviews) but the valve does not appear to work at all.

We have the pump installed, and it works well. The pump only starts when we push the button connected to the unit, or when we push the button on the remote control. When the water temperature is reached, the unit stays off until the button is pushed again.

I feel like it is not getting full water supply. That is the only reason I know of that it would do that. How are you running it, like, in line with another pump or what? You may want to rebleed all your lines and then check it again.

Not sure what tour question is, but am wondering if you turned off the water supply before installing. I've forgotten this step and had it leak. Once I redid the installation process, it worked quote fine. If that's not the problem, maybe it is a defective filter? Wishing you luck.

I think it's possible you have your plumbing hooked up wrong. Did you hook the cold water hose to your sink's hot water and your hot water line to the cold? That could be why you get cold water when you turn your valve toward the red hot water. Also, go to luxebidet.com and send them an email or call them. They will get you figured out ... they are wonderful.

It should be installed at the furthest distance from the water heater so all locations have hot water each time the system is run. This was per the instructions. It is also how the system was originally installed in my house when it was built.

I have a hot and cold system and it works like a dream. The water goes from filter to separate heating tank however. Not sure how your system is set up.

Dear Michael, I am sorry to read that you are experiencing problems with this heater as well - it sounds like exactly the issue we had. Please avoid the mistake I made and do not spend thousands on attempts to fix it. Please read my review to get a sense of what we experienced and don't waste any more time and money on this product. By the way, the water heater I replaced it with is still going strong and I haven't had to think about hot water since I got rid of the Bosch. Best of luck!

Mr. Schafer and Mr. Dave have mentioned two good things to look at. I think a kink in the hot water line to the faucet is the most probable cause. But you should also check the shutoff valves emerging from the wall below the faucet -- if the hot water valve is only partly opened, it will restrict the amount of hot water available at the faucet. So make sure those shutoff valves are fully open ("lefty, loosey" or counterclockwise, if you prefer) for both the hot and cold supplies.

The recirculating pump runs continuously when turned on. The valve simply controls when hot water begins to seep into the cold water line which is what makes the hot water always available at faucets with the valves installed. Depending on the pump you have, you can either program it to run 27/7 or as I do, program the timer on the pump to be on at certain times and off otherwise. Mine is programed to be on from 7 am to 9 am, then again from 9 pm until 11 pm. I also can override the timer when I need hot water at unanticipated times. If you run the pump continuously, it will greatly increase the amount of energy used to keep the water heated. Hope that helps. The recirculating pump runs continuously when turned on.

Mine when 1st hooked up didn't run hot so my plumber switched the hot and cold line...and it works great

The water is hot even in cold climate. My basement is not heated and shower is on 2nd fl I don't have a problem. Realize that the cold water already in the pipe has to come out first so it takes a minute to expel that.

I've had this happen when someone runs hot water through the filter (which the instructions say not to do). Warm seems to be ok, but occasionally a guest will try to fill our kettle with hot water though the filter. It's also happened when debris blocked the small opening of the valve after the water main was turned off and back on for repairs. You can remove the fixture from the tap and clean the valve out by running water through it the opposite way.

When I originally put mine back together, I assembled it incorrectly - limiting my hot water. I went back and realigned the gears on the temperature selector so that it would give me the entire range of temps.

The pump is on a timer set by your needs.........It comes with a "Comfort" valve which installs under the sink which is basically the farthest from the water heater. We have found that now the whole home gets hot water extremely fast since the installation of the recirculating pump. Honestly we couldn't be any happier with the system and should have had it installed long ago. It saves on water too.

You can just let the water run and you will get hot water just as if the pump is not there. Also, you can turn on the pump with the built in switch. Mine is in a location such that it is not easy to get to. If we are going to be away for a week or more I will make the effort to shut the pump off.
