Why is tank in attic overflowing?
The overflow (also called the expansion/vent pipe) from a copper cylinder runs into the cold water feed and expansion tank in your loft. This pipe allows for the water in the cylinder to expand when it’s heated. It’s normal for the overflow pipe on a copper cylinder to drip when your water is heating.
Why do I have two water tanks in my attic?
Why are there two water tanks in your loft? If you are not sure why there are two water tanks in your loft, it is probably because the property has (or used to have) a vented central heating system. Water from the mains is fed into the larger of the tanks which is the cold water storage tank.
How do you control water tank overflow?
In addition, there is the best way in solving overflowing water tank by installing automatic water level controller because this helps in regulating the flow of water in your water tank and it optimizes the performance of the rainwater harvesting system.
What is the large water tank in the loft for?
The Header Tank is the smaller of the two water tanks usually found in the loft, the larger one being the cold water storage tank. The header tank is used to fill the heating system and accommodate the expansion of water during the heating cycle.
Why is a leak coming from the attic?
The most common leaks coming through the ceiling from the attic would be the float operating valve followed by a burst pipe due to the cold or a joint on the pipe work that may of been knocked at some point.
Why is there a leak in my central heating system?
Why do leaks occur? The most common reason is that if the pipes are not properly protected, ie if the pipe work is copper, then the acidic nature of the concrete of a period of time will slowly start to eat away and corrode the copper pipe and/or fittings.
What should I put on my central heating pipe to prevent a leak?
The pipe should be properly covered and protected with Petrolatum Tapes (common brand is Denso) this will prevent corrosion if installed correctly. In this instance, literally thousands of tiny hairline stress cracks form within the concrete slab as the concrete slab settles over the years.
How can I tell if my central heating system is sealed?
Do you have a sealed central heating system ie a combination boiler or system boiler, another way to identify your system is to check and see if you have a small expansion tank or ‘header tank’ as some installers call them, if you do, you don’t have combination or system boiler. We will deal with conventional boilers further down this page.

Is it safe to install an attic expansion tank?
Where an attic expansion tank is installed the boiler may depend on the expansion tank and its overflow for safe pressure release. Such systems are less safe than modern hot water heating systems that include a pressure and temperature relief valve right at the heating boiler.
Is there a header tank in the attic?
At below left is a small wooden box lined with galvanized metal found in the attic of an historic home in Vermont, in New England. This header tank was quite small, certainly not large enough to be used as a water supply cistern. Its piping was incomplete, making clear that it had been abandoned.
What should I do if my attic overflows?
Overflow from attic expansion tanks that are open to atmospheric pressure typically run outside to a roof gutter and drain system (risking freezing and blockage in some climates) or the tank may be connected to a building drain. Some attic expansion tanks were intended to be drained manually if needed and may not be piped to a drain.
