Every time i turn on a HOT tap in my house there is all ways a lot of air in the pipes, i run the tap for a bit and it seams to go but not properly, and it is still in the pipes the next time i turn it on. Anyone help.

Check tank is filling quick enough.

If the ball valve isn't opening fully, the water may just be trickling into the tank, if the tank is emptying quicker that it is filling it will draw air in.
