Water Tank In Attic Constantly Filling

Notice the overflow pipe from the attic leaking climbed up and checked the cold water tank and noticed that the ballcock was no longer working and the tank was constantly filling.

Water tank in attic constantly filling.

As the water level rises the ball rises to switch the water feed off again when the tank is full. The evaporator will then not operate properly and the humidity level will be higher in your home and in the air handler. As this water leaves the cylinder cold water flows into the bottom of it from the cold tank. Other things to consider include a constantly flowing toilet.

When this is the situation your best move is to purchase a new water heater. The ballvalve in it should be replaced if it s dripping. When the water in the tank is used its level goes down and so does the ball and arm. This movement turns the cold water feed on so the tank refills.

You can adjust the pressure with a pressure reducing valve. In some cases the sediment build up can reach a point where flushing the tank is no longer possible and may cause your tank to leak. We always had some noise with the old valve but i must agree this is much louder. Hot water expands and requires relief.

It is doing what it is supposed to do. I recently replaced the ball valve on my cold water tank in the loft but ever since then my wife has complained about the loud whooshing noise as the cistern fills. Reducing the flow into the house from the main stop cock outside might help. The other things could be that the heating itself is expanding too much and overflowing.

However some homeowners choose to wait for their heater to fail. There are several reasons why the condensate line will clog and then the drip pan will fill with water. You may have an expansion tank to handle this or you just have an open vent that runs up and fills into the cold water tank in the attic. To replace the ballcock valve you must first turn off your mains supply to your attic tank.

Bought a new valve and ballcock and installed problem was still continuing. Does it always drip or only when the heating is on. One is that the evaporator is filled with debris like hair dirt or dust. The valve is a type 2 high pressure.

The maximum water level in the tank should be about one inch below the overflow pipe.
