Why is my water meter continuously moving even though all our faucets and fixtures are closed already?

If your water meter is registering flow even when all fixtures are closed, it can be due to leaks in the piping system, unauthorized taps or backflow of water to the mains.

Backflow of water can occur if you are using an overhead water tank system and the pressure in your overhead tank is higher than that of the mains (Nawasa).  If this occurs, install a check valve after your water meter to prevent backflows and unnecessarily high water bills.
