The drain valve on my hot water tank is dripping from the outlet (controlled by the red switch)....
The whole thing is only about 2.5 years old so want to avoid calling a plumber if possible.

It may be that even over this timescale, some calcium is stopping the red switch from fully closing. I have tried the anti calcium formula sprays to no avail Is there a simple solution to stopping the drip?
