Attic Water Tank Overflow

If not then u will still have a expansion tank in the attic with an overflow.

Attic water tank overflow. The tank supplies your bath and basin taps and your hot water cylinder with water. Take the lid off each tank and check how high the water level is in each one. The cold water feed and expansion tank overflow pipe runs from the large water tank in your loft to the outside of your house. It s not likely to be a catastrophe and the flow may only be a trickle but if you have a water meter and pay for your water obviously the cost of this wastage can add up.

That mysterious pipe is the overflow from the cold water header tank also called a cistern in your attic. The water level in a tank is too high so it is running out the overflow. It will be made of either plastic copper or lead and usually leads out through the eaves and soffits. Before you remove the old ball valve you must ensure that there is no water still coming even when the valve is open which is when the float ball is hanging down.

If in doubt get a plumber the mains water supply to the attic tank has the potential to create a bad flood if anything goes wrong. Go into the loft and take the lid off each tank.
