Hydrant Maintenance Dry hydrants require regular maintenance. Each hydrant should be inspected quarterly. Clear away any trees and underbrush that may make it difficult to locate or access the hydrant. Also check for aquatic plants or silt that could clog the screen. Backflush the hydrant quarterly and conduct a pump test.
Regular inspections offer a great opportunity to train new fire department personnel.
If a dry hydrant is located on private property, get written permission at the time of installation to access for inspections and emergencies. It is always simpler and cheaper to install a dry hydrant as the pond is being built. For More Information National Fire Protection Association.
