This may be a dumb question but if the return is the cold water line doesn't it heat up the cold water for the rest of the faucets in the chain.

The water is only passed through the valve if the temperature of the warm water pipe falls below a certain value. In my experience, this is enough for the first 5-10 seconds of "cold" water to warm up a little. I never felt a difference in other faucets in the same chain, but even if there was a difference, it arguable couldn't be greater than the 5-10 seconds on the faucet with the valve.

Yes, the cold water is a little warm, but it flushes through within a few seconds. We have it timed to go on in the morning for showers and on again late afternoon until 8:00 during dinner preparation/cleanup. Saves so much water when showering or doing dishes.

Yes, it briefly warms the cold. So you need to run cold for a second to dump the warm water. We've found it great to have instant warm water, before we installed the pump we had to run hot for quite a while before it warmed up. It's a long run from out hot water tank to the bathroom. The pump has several timing options so we have it set to come on in the morning and shut off at 10pm. Hope this helps

Yes, the cold water is a little warm, but it flushes through within a few seconds. Certainly not long enough to be objectionable. It's a small price to pay to have the hot water available within seconds! This pump is wonderful!!!

Not enough to be objectionable. The flow is very low once the thermostatic valve receives hot water.

Actually a valid question, you will experience a certain amount of warm water when the cold water is turned. But I myself personally have never found it to be a problem. The warm water on the cold side is quickly flushed out and cold water comes in a few seconds. Hope this helps, May God Bless.

Yes, the handle returns to vertical but does not go backward. It goes forward to get both hot and cold water.

I used this faucet for my three-hole sink (one for the faucet, one for cold water and one hole for hot water. With one hole, I'm not sure how separate hot and cold lines would connect to the faucet. The product description says it is for a three-hole sink. Good luck.

This unit only heats water supplied to it under pressure. I would think however you get cold water from you tap would supply the cold water to this heater. If your cold water faucet also activates a pump the same would be needed for the hot water faucet.

Good question. All depends how much heat you have going out your pipe. If it has a automatic fan on it there may not be enough heat in the pipe to make enough heat for the fan to work. Joe

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.

I have both single and double valve faucets and it works well for me. Be aware there has to be a return pipe from the plumbing point furthest from the pump. It is not one of those 'passive' systems that recycle water back down the cold water pipe. I found it to be a real quality product. Mark

it does not heat-up the water. it protects the water from freezing. it does work really well to keep hot water from your faucet hot all the way to your pool or whatever you need. the pirit hose is stronger and thicker than a normal hose so it handles hot water pretty good and helps hold the heat in.

It's a cold water washer. Never tried with hot water, and I don't think it works.

I have to open my faucets all the way to start it. There is a small amount of water in the unit that gets extremely hot all at once and heats the water exiting the unit. When there is enough water exiting the unit to ensure safe operation, it will turn on and do what it was designed to do. If the incoming water is very cold, or the faucet you want to use is far from the unit, you may need to turn it to maximum power (5).

Yes it does but only cold water. It's in kitchen sink where hot water is used more .

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.

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.

Yes, cold water control goes forward. At most, the handle may go about 1 cm behind the faucet. We have backsplash and had the same concerns but there is plenty of clearance (1 3/4 inches) between backsplash and base of faucet.

No. The pump only circulates cold water out of the hot water pipes and into the cold water pipes. If your shower goes cold, your hot water tank ran out of hot water and circulating the water further isn't going to make it hot again. If you keep pressing the circulate button after all of the cold water has been circulated out of the hot water pipes (and there is still lots of hot water in the tank), the pump will run for about 30 seconds each time the button is pressed. And if you press the button enough times, your cold water pipes become full of hot water. You then have the opposite problem-- hot water comes out of your cold water outlets and you waste water running it to cool down.

Hi, I guess it's how your plumbing is set up. For me, all water goes through the water boss softener. So the cold pipe that runs into the hot water tank is softened first. This company used to have great customer service but I've found it's not so great since I bought my second one.

Unlikely. The water is split after the filter and goes to the hot tank and staight to the cold-tap. But the hot/cold tap, filter, and water lines can get naturally warm from heat let off from the unit and of course right after you dispense hot water. Check under your sink and it will be a few degrees warmer due to the heat from the tank. For cold you need to let it run a few seconds (5 or so) to cool it down but even then it may take a lot longer to get as cold as the regular faucet.
