Why does my water run hot at times when I am watering my flowers? Also, why does it take so long for me to get cold water when I need it?

The valve/using the cold water lines as your return lines system is imperfect. What happens is you are filling the cold water line with hot water recirculating to the water heater and you have to run it out before you get cold water. In theory, the valve is supposed to close when the water at the faucet is hot enough but it does not always work as advertised and your "cold" water would still be warm anyway. The way to completely solve this is to abandon the valve and install a return line directly from the last hot water appliance in each main hot water line all the way back to the water heater, and into a tee at the drain line. This way the cold water lines are unaffected. The valve/using the cold water lines as your return lines system is imperfect.

I don't know for sure about your plant watering. Are you watering indoor or outdoor? If indoor, then this means that your pump is "on" and working to keep hot water in your pipes. I would try to either reset your timer to run at times of day when you need it most, like bath time and off when you could use cooler water around the house. Basically, when the pump is running, hot water is in your pipes so your pipes are "warmed" by this, and that could be the result of the cold water taking longer to show up. I go to the farthest part of the house to access cold water if I need it during my pump on time. Just my best guess at your situation. Hope it helps. I don't know for sure about your plant watering.

It's the nature of the system. This is why I wrote a negative review on the product. Wait until the bacteria starts growing in your toilets. You'll always have hot water and you'll always have difficulty getting cold water. There's no point washing fruit or produce with water going through this system.

If your getting Luke warm water in the cold to other fixtures by the valve the valve has gone bad. The pump should feel cool not hot to the touch and a slight vibration as it is a very low horsepower pump. As a plumbing contractor I find the comfort valve being the problem most often. However if the pump is quite hot the motor has frozen and will get rather hot.

I highly recommend warming the water first. Using cold water can be very uncomfortable.

Cold spells, yes, I've experienced it as well. I guess it doesn't want to overload or burn itself out in some way. We had to keep the flow low to get hot water. I don't think it can handle two showers. the inlet is small, and when you look inside, the valve inside makes it smaller. I got two years out of mine before it died.

Mine is full of water and on all the time, so I have instant hot water. It would be pointless to have to wait for 5 liters of water to heat.

I would think you could use warmer water. We have our connected to a garden hose, which is is designed for, so it's cold except for any sun warming on the water when it's sitting out. It's plumbing pipe so should be OK for normal tap water temperatures.

When I plug in the ones I have they get fairly hot within an hour or two. That's how I know it's working. The heat is necessary to evaporate the moisture from the silica crystals. I recently recharged a couple that had been neglected and it took three days to evaporate all the water out. I'm happy and very satisfied with the units I have so far.

The water will come out cold until you have used the faucet for quiet a while. I don't think you can have the water come out hot unless you just run the water.

cold water works great. to hook up hot water you would have to run a line from the sink

As long as you wish :), the water will get cold in 5-7 min, but I keep adding hot water... I do it for 20-30 min total.

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.

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.

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.

The handle has to be pushed to the left closest to the stem. If you push it back you get hot water, front is cold water. Hope this helps - it's a great buy and a nice faucet!

I have not experienced that problem. The problem we had was not getting any cold water. After many calls to Delta I finally got someone who said the problem was with our hot water circulating system. Once that was replaced there have been no issues.

It heats the water rather nicely. I have even had to turn the heat off because it got to hot. I still start with warm water just so it heats up faster but have put in cold water before. It took about 5 min to warm up to a nice temperature.

To the degree that you are pumping out warm water, it may be warm. But if it's actually too hot to touch, something is wrong. It's working too hard.
