A Good Flushing

The final process that takes place prior to connecting the lateral pipes to the new mainline is a flushing. It is critical that all debris that has gotten in the pipe during construction is removed.

The easiest way to do this is to pressure up the line and open up drain valves to blow out any debris that may have found its way into the pipe. If this is not done correctly, the debris left inside the pipe will cause problems to the operation of the new sprinkler heads.
