CARVER CASCADE 2

You have gas water heater with working burner.
But not getting hot water at faucet?

1) Bad faucet cartridge. Test for crossover. Copy following link:

2) Is there hot water inside the tank? Open drain valve and check for hot water.

3) Drips and leaks: Turn off all taps and put ear against pipe and listen for water leak.
Water leak can run all the hot out of tank.

If all the other faucets work, then the problem is the mixing valve in your shower. You will need a new shower fixture.

Water heater is heating water but only luke warm water arrives at faucet.
Open TP valve and confirm that hot water is available.
If water at TP valve is hot, then problem might be plumbing-related, for example crossover.

It sounds like your thermostat on the water heater isn't working properly. try turning it up higher and if this doesn't work I would have a service techy look at it.

Also check that by-pass valve(s) is/are, in proper position at back of tank.

Possible thermostat problem. Are you experienced enough in that area to do some testing. Have a multimeter? If not experienced, don't try it, too dangerous. Call in a service person.

Check the tank drain valve for water there.If you get a good water flow there you know the tank is getting water pressure.Check the first outlet downline from WH and if there is no water there you have a blockage or other problem.If you have to turn off water to tank, remove the outlet pipe ,and check for water flow from tank with in valve on.If no flow, tank is plugged up.
Hope this gets you going.

your pipes are clogged, what if you were to not turn on the cold and turn on the hot does any water come out at all, with just the hot side turned on,, if not there could be a valve that has been turned off, or the pipes are clogged

is the cold side hooked to the cold side if not you will be feeding the unit backwars making it to where the cold is just comming across the top of the tank, check the dip tube also, this makes the cold water go to the bottom and push the hot out of its outlet,, how many faucets are involved, if just one might want to check the cartridge to make sure it is working properly
