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

No hot water coming out of tap but we do have cold water out of cold water tap...any suggestions??


Check your by-pass valve(s) at back of water heater. Water goes in cold to bottom fitting, and out hot at top fitting, so those 2 valves ( if any) need to be open, anything in between needs to be closed. There are a few different by-pass set-ups, so if that doesn't explain it, get back to me with a description of your valve set-up and I'll guide you through it. If valve(s) are all in proper position and still no flow through hot line, I'd suspect faulty check valve in between hot line connection and tank.

Only about a cup of hot water will come out, then it gets cold.


You need to check 2 things. First, go outside and carefully open pressure relief valve at top of tank,(careful in case hot water spurts out) and make sure there is water in it. Second, look at back of tank inside RV and check your by-pass valves(s) for proper positioning. Cold water enters the water heater at the bottom fitting, so that valve has to be open, as well as leaves water heater at hot fitting at top of tank (the highest fitting) so that valve as well needs to be open. Any valves that may be in between those 2 water lines need to be closed. I am assuming that the heater starts runs, shuts down etc, just not running any hot water through hot side of taps, correct?

Turned off the hot water to fix a leaking tap. now the tap has no hot or cold water and the hot water tank valve is leaking?


It sounds like two problems.
Problem 1) Clog inside faucet or clog inside pipes at faucet
Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
My bet is clog inside faucet.

If you have galvanized pipe that meets copper pipe, this can be trouble spot.

Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

If cold water shut-off is leaking, then replace shut off.

If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

If TP valve is leaking, then replace with same temperature and pressure rating.
New TP valve threads need teflon tape to seal pipe.

Problem 3) If pressure is low all over house:
Buy pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

Test pressure on water heater drain valve.
This says if pressure problem is before -or- after water heater.

If problem is before the water heater, then shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.

Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
Read articles above about clogs inside water lines.

Carver cascade 2 No water at all comes out of the hot water outlet. The inlet non return valve has been changed & is working correctly.


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.

CARVER CASCADE 2


Hello .. when an electric water heater only gets warm, it is usually the thermostats. I would replace the thermostats, make notes where the wires are connected .. make sure after replacing that the back of the thermostat is flat against the metal of the tank.

No water coming out of hot water taps, water is getting hot in the tank, we have changed the non return valve it izs a cascade 2 that is whot it says on the outer cover of the caravan


I'm not sure I have the whole picture here but When water simply will not flow from a tank your first guess that it is a faulty valve was a good one. While you had the valve off did you turn on the water briefly to verify that it flows well at least up to where your valve was? You may have to do this test. The clog could be right at the tank itself. Before you open up the pipe again first look for anything steel. I have found steel plugs screwed into an old threaded outlet on a pipe that has, over time, produced a large rusty blob that has blocked the flow of the water. If there is nothing like that going on you will have to open up the pipe. By the way, if hot water flows at any other locations, like the tub, then you know that the problem is not at the tank. you have to figure out where the blockage is by a process of elimination.

Water pump does not work when i turn on hot water tap


Since the cold water works, the problem is not the pump. Look for a blockage or possibly a major leak in the hot water system. if you have a kitchen sink and bathroom sink, are both hot water outlets not working? Does the water heater have shut off valve , or is its drain still open from when you winterized it (and the water running out to the ground instead of to the faucet?
