Using A Smaller Pipe to Increase Water Pressure

There is a very persistent misconception in the lawn sprinkler industry that using progressively smaller pipe sizes in a sprinkler system will help keep the water pressure high. The argument is that as the water moves through the pipes past the sprinklers, the pipe must get smaller in order to squeeze the water so … Continue reading Using A Smaller Pipe to Increase Water Pressure →
