Measuring water temp is a good idea. I was turning down a water heater for someone (water temp was something like 65 C) and thermostats were set for less than 50. Turning them down to ~40 got me to 55.

How would I measure the temp? Is there a specific drop amount by the time it comes out of the tap?

Okay this is weird.. !!

I turned off the cold valve coming out from the tank and there is no hot water in the house.. I turned the cold back on and the hot water is back.. I thought maybe they are crossed but if i touch the hot side its hot and if in touch the cold side its cold

a) top of tank should be labelled hot/cold (directly in the metal of the tank or with a sticker). Unless something has gone severely wrong, your cold side is on the right (humidifier takeoff on that line, anti-scald on the other line).
b) shutting off the flow of cold water into the tank shuts off the flow of hot water out (there should be no air in there to act like a pressure tank). You may get a second or two of flow after shutting off the cold, but not much more.

Ghost you are right!

And i figured out what is wrong..

As you said the white hose on the right side of the picture feeds the cold water from the city into the tank to be heated.

The red hose on the left side is the hot water coming out from thank and it also gets mixed with the cold water coming from the city so that the hot water is not burning hot..

The problem is ---> this cold water hose that is mixing with the hot so to stop the scalding, it is back up about 10 feet hot to the point where it is about a foot away from the cold water splitting off to go to the taps...

I am a plumbing moron and it tool me a while to figure out all the pipes tonight.

So my question is .. The cold water that mixes with the hot to stop the scalding should it not be on some sort of one way valve where only the cold goes in but the hot does not come back thru?

close off the valve on the right there that feeds water to the tank.

then go to every faucet and test if you are getting water flow from the hot side.


if you have a flow of water from any taps u got issues that need to be located. listen for hissing.
