Hydrant Cap Check Report

Summary:

During a fire training in late May of 2021, a 4” fire hydrant cap was seized when undergoing the first run through of the training. The seize took up to ten minutes to resolve and broke a hydrant wrench in the process. It was determined that other hydrant caps in the

Boulder Basin area should be checked for the same issue. Over the past two weeks, 53 hydrants in the area have been checked, with the conclusion being that many caps require service for residue buildup, rust, and gasket damage.

Process:

The process at each hydrant began with a general check over of hydrant location and accessibility based on provided hydrant maps. This was followed by the removal of each of the three caps on the hydrants. Any seizures were documented and then resolved, primarily by striking the sides of the caps with a rubber mallet several times. Once the caps had been removed, threads were inspected as well as the gaskets for residue buildup, rust, and damage to gaskets. Caps were then replaced hand tight. Findings were documented in the comments section of the excel report.

Findings:

Out of 159 caps removed, both the center 4” cap and two 2 ½” side caps on each hydrant, 16 were found to be seized. Seizures were defined as the inability to remove the cap under strenuous effort using a hydrant wrench, requiring additional remedial measures to operate the cap. This equates to about 10.06% of all caps. Some were unable to be screwed in all the way flush with their threads, creating potential for leaks during operation. In addition, out of 53 hydrants, it was found that 10 were obstructed, ranging from completely inaccessible to increased difficulty of access/operation. Out of these 10, 3 were completely inaccessible due to plant overgrowth, and are therefore labeled as unknown for seizures and condition not recorded. (See Figures 6‐7) Residue buildup, rust, and gasket damage were found on over 50% of all hydrants. Residue buildup on the threads was prevalent, often visibly falling off when unscrewing caps, and sometimes causing difficulty in removing them. High amounts of rust were present on the interior of many of the caps as well as some threads. Gasket damage was common throughout all caps, ranging from light wear to heavy damage, such as deformation and tearing. (See Figures 1‐5)

Conclusion:

In conclusion, the risk of complete seizure by a hydrant cap is low, coming in at only

10.06% of all caps tested. However, given the effect this would have on response time if it was to occur on scene, it is something that should be addressed. Many of the seizures were likely a result of the high buildup of residue and rust on both cap and outlet threads and interior. A thorough cleaning and lubing (anti‐seize) of these threads/caps, a quick and easy task, would go a long way in preventing seizures and securing ease of opening and closure. This process could be delegated to a private company or done by NPS maintenance (see video link.) In addition, hydrants that were marked as obstructed should be addressed and remedied as soon as possible to secure ease of access in the event of an emergency. Most of these cases are related to plant growth surrounding the hydrants that could be altered easily.
