How does this valve stop the hot water from running into the cold water side when there is a CW pressure drop (such as running a garden hose)?

The water does run from the hot water pipe into the cold water pipe and back to the hot water heater. It works great. I have not noticed any hot water coming out the garden hose when the pump is on. This system was first recommended to me by a Hospital Building Superintendant which uses a commercial version of this same system. I highly recommend installing this product to save water and get hot water when you need it.

The valve gradually closes with the rise in the temp of the water passing thru and will close completely at the predetermined temp. In any case the hot and cold water pressure in the home is always very near the same sense it hasa ccommon supply.

The valve stop is heat activated and will close when the hot water flow has heated it sufficiently, regardless of the cold water pressure.

The valve responds to temperature differentials between the hot and cold side, not pressure.

The water is fed into the chamber by power being applied to a solenoid valve. The water flows over the media where the warm air passes through it adding humidity to the return air. Any water that does not evaporate into the air stream flows to the bottom of the chamber and is drained out of the unit via 1/2" hose. The only way that there could be an overflow situation is if the 1/2" line got blocked. Proper installation and regular basic maintenance should avoid that.

Yes.The water supply line passes through the filter, then goes to either the heater tank or the cold water spigot. Three lines go to the valve: filtered cold water to the faucet, filtered water to go into the heating tank, and hot water returning from the tank to the faucet.The hot water is supplied to the faucet when the red control valve pushes supply water into the heater tank, displacing hot water back out to the faucet. In this fashion, the hot water tank is never pressurized.

Weird. Is the hot water valve all the way open after installation? Do you have good pressure with cold water? If not is something under the sink pinching the hose? Never heard of anything like this. BTW I'm just a consumer not a plumber.

No, it's only one valve that controls between hot and cold water. There IS a Delta fixture similar to this one that DOES divert water between the shower head on the wall to the shower head on the ceiling.

The water pressure from the motion sensor on the top or front of the faucet is fixed and is based on the flow from the water supply value to the electronic control module. If you want to vary the water pressure or temperature, you should use the manual valve on the right bottom side of the faucet. Strongly recommend the AC adaper. Great faucet!

The force of the flow and the temperature are at the faucet . The hose valve & wand button only are on/off. It is simple install and operate.I had no problems or leaks following the manufacturer's instructions.

It attaches to the faucet directly and does not plug in. If you run cold water, you will get cold water. In fact, you should only run cold water according to manufacturer.

Open vent faucets allow the "instant hot" tank to run without a temperature and pressure relief valve as is found in your domestic hot water heater; the tank normally runs at atmospheric pressure (is vented through the faucet spout itself) and is only pressurized to the extent that when you open the hot water dispensing valve you are actually allowing cold water to enter the tank thus forcing hot water out through the spout, which is always open through to the tank. When you release (close) the hot water dispensing valve the cold water supply to the tank is once again shut off, ending the flow of hot water and leaving the tank vented through the faucet. This method of avoids/solves the problem of providing a safe method and place to vent a tank overpressurized as a result of a stuck thermostat.

I bought two valves from Lowes. Same problem at first: as long as it's hooked, water just run through. What I found was this is the default status for the valve. To solve it, you need to connect it to the timmer, adjust to manual watering for 1 min, when 1 min is up, the valve shuts off. No problem.

This is actually a two-part quiz. First, there is the valve on the back side which hopefully has been adjusted to allow the full flow of cold to hot water. Second, once installed, it's designed as a set and forget temperature gauge on the bottom, and a water pressure flow on the top. You'll love it. Enjoy!

There's a plastic lever on the left side of where the wires hook up. Make sure the valve itself is seated properly., and slowly pull the lever down. You should hear the water rushing through the system and your heat will work until u figure if your thermostat is bad of the wiring is not right. Good luck

I agree to procedure made by Ben Percy. I would add,turn off cold water valve to prevent pouring out of water from quick connect mounted on wall of cabinet beneath sink. Sometimes it may be difficult to twist new filter up clockwise. If pressure pin (valve) becomes stuck, water will pour out from port that filter inserts into. I am suggesting to close off main cold water line to filter.My past experience has been water flooded inside of my cabinet.

The first two responses are very good. One addition check, make sure the cross-over valve is installed correct, not inverted. If inverted the check valve within the crossover will now allow cold water to flow back into the hot water line instead of how water into cold line. By following these recommendations you should be able to identify the root cause and diagnose the issue. Good luck.

Neither. It is just a faucet adapter with an adjustable valve that allows you to lower the water flow to a steady drip. There is a stainless steel spout as shown in the picture and the rest is plastic tubing, the leak valve and the faucet adapter, which has a Y-junction and shutoff valves to allow you to still use a garden hose.

There is no pressure controller / valve. This is one thing I mentioned in my review, that I also wish it had. It simply runs at full blast once you turn the faucet on. One small thing you can do tho, is buy a water restrictor or cut a rubber washer to fit the hot and cold lines. That will reduce the flow of hot and cold and thus reduce the pressure. If you use the handheld shower mostly, you can buy a shower head water restrictor (they are literally only $1.00... go to True Value... Home Depot and Lowes don't sell oddly enough!), and they restrict shower flow to 2.5 gallons per minute which is green and eco-conscious! But the restrictor will literally restrict / lessen the flow and the pressure.... ;-)

If you set the faucet up where the handle is on the right, the further you pull the handle out to the right, the stronger the stream of water. If you pull the faucet forward (again, if connected to the hot and cold water hoses properly), you will get cold water (or if you live in Texas and it is summer, you get warm water!), and if you push it back you will get hot water. There is not a lot of range of movement in the handle and it takes a little getting used to, but I LOVE mine!!
