Why is my hot water tank cold?
The most common reason for a dip tube going “bad” is because it’s disintegrated away (or has started to). And when this happens, cold water no longer gets pushed down to the bottom. Instead, it mixes with the hot water at the top of the tank. Which means, your hot water supply quickly turns lukewarm/cold.
Why is hot water back flowing into cold water tank?
This happens over a period of a 90 mins (water is only heated for 20 mins). Having looked in the tank I can see that water is being backfilling the large cold water tank not via the open vent pipe but the pipe at the bottom of the tank where the cold water should flow to the Cylinder.

that stopcock should be left open and the ballvalve will stop the water when the tank is full. – the crusty valve (2) as in the first photo is on the pipe from the overhead tank to the hot water cylinder and takes the cold water from the tank and feeds it to the cylinder to give hot water.

Why does my water heater not have enough hot water?
Again, if you don’t have enough hot water, the reason why will depend on the type of heater you have. If you have a heater with a tank, it may simply be that your tank is not big enough for your requirements. If your tank is too small for the number of people showering, for example, you may use up all the hot water before everyone is finished.
How does a vented cold water tank work?
Cold Water Tank. The cold water tank in a vented cold water system stores the large volume of water to supply the hot and cold water systems that are not directly fed by the rising main. The water level within the tank is controlled by a float operated valve which is set to allow water to enter when the water level drops below the required level.
Why do I get cold water when I Turn on the water heater?
The tank fills up and the water gets hot but when I turn on the hot water at any faucet all I get is cold water. I checked the valve and it is open on the water heater. There are three valves: one is the cold water feed and one is for hot water, and there is another pipe that runs in between the cold water pipe and the hot water pipe.
What to do if your hot water tank wont stay lit?
If your hot water tank won’t stay lit, one of the first things you should check is the thermocouple. The thermocouple is a device that checks if your water heater’s pilot light is on. If the thermocouple has been damaged, it may think the pilot light isn’t on and not light your water heater.
Why is my hot water tank not draining?
If you turn on the hot water at a faucet and nothing comes out, this is an indication the supply valve was never reopened after draining the tank. Remove the metal plate on the front of your hot water heater, if it’s gas operated, and look through the glass panel to see if the pilot light is on.
What to do when your hot water heater wont turn on?
Check the cold water supply valve to see that you’ve reopened the cold water inlet leading into the hot water heater. If the valve has a round knob, it should be turned clockwise to open the valve. If the valve has a straight metal lever, the lever should be parallel to the inlet pipe for the valve to be open.
