Can you drink water from a cold water storage tank?
There have been many documented cases of water from storage tanks being contaminated. So, you can only drink the water from a cold water storage tank if there is no algae growth. Even then, it doesn’t hurt to have an extra filtration system in place between the tank and the taps.
How can I replace the ballcock on my water tank?
Have a look at the ball valve you currently have. Buy a similar replacent. And buy a new fibre washer too. Isolate mains water and open the downstairs cold tap to release the last drop of water in the pipework. Then change it. 2 spanners and 10minutes later you can sit back and admire your work! Have buckets and towels ready just incase!!
What kind of valve does a ballcock washer use?
If you push the float of the ball cock downwards and no water flows into the tank, you have found the right valve. Usually valve 3 (shown in the diagram above) feeding the tank is on a 1/2 inch / 15 mm pipe. The valve on this tank is a slider type. Inside the body of the valve is a nylon or brass slider with a rubber washer embedded in the end.
How does a cold water header work in a hot water tank?
The second function of the tank is to provide a pressure head and feed for the hot water tank (gravity feed). Water flows out from the bottom of the cold tank (the blue line in the diagram below) to the bottom of the hot tank. Because the cold tank is higher than the hot tank, the resulting pressure forces water through the tank and out the top.
What’s the best way to adjust a ballcock valve?
With your other hand, grasp the arm just before the ball float. Bend the arm downwards so that it ends up being curved downwards. Water will now force the float to act on the arm and close the valve at a lower level. Newer style ballcock valves have a screw for adjusting level.

How does a header tank stop water from overflowing?
The hole towards the top of sinks is there to prevent water overflowing onto the floor and header tanks have a pipe that works in the same way. In the feed and expansion tank, there will be a float valve (another name for ball valves) which controls the flow of water into the tank.
