Water Tank In Attic Constantly Filling

So you will still have a small tank in the attic to feed the heating system and to allow for expansion.

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. This movement turns the cold water feed on so the tank refills. Hot water expands and requires relief. 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. There may be a valve outside the tank near the ballcock valve but otherwise you will have to locate the stopcock it is often under the sink in the kitchen and use this to turn off the water supply to the entire house. To replace the ballcock valve you must first turn off your mains supply to your attic tank. 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.

The maximum water level in the tank should be about one inch below the overflow pipe. There are several reasons why the condensate line will clog and then the drip pan will fill with water. 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.

When the water in the tank is used its level goes down and so does the ball and arm. 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. The evaporator will then not operate properly and the humidity level will be higher in your home and in the air handler. However some homeowners choose to wait for their heater to fail.

The other things could be that the heating itself is expanding too much and overflowing. Bought a new valve and ballcock and installed problem was still continuing. Does it always drip or only when the heating is on. It is doing what it is supposed to do.

Other things to consider include a constantly flowing toilet. You can adjust the pressure with a pressure reducing valve. As this water leaves the cylinder cold water flows into the bottom of it from the cold tank. The valve is a type 2 high pressure.

It wouldn t be pressurised then.
