For a Traditional Cover
To measure the size of the bore cover use a tape measure and measure the distance across the concrete liner. You need to measure from the outside of the concrete liner to the outside of the other side.

For a Flat Cover
We need you to measure the outside diameter which is the distance from the outside of the concrete liner to the outside of the other side and the Inside diameter which is the distance from the inside of one side to the inside of the opposite side.

It is a good idea to measure this diameter in 2 directions because some of the old liners are bigger on one side.

Do not do this if you believe there is any chance you may fall in to the well. Do not send children to do this task.
