Fire Hydrant Preventative Maintenance and Repair Services
Are you responsible for a fire hydrant on your property that has not been tested in the last year, or one that is leaking, seized, or missing parts? Our licensed team at Seadmok Water Construction LLC keeps private fire hydrants across Anne Arundel County in a constant state of readiness, the same standard the County's own Water Line Maintenance Division holds its public hydrants to. We test PSI and GPM, flush, lubricate, and repair hydrants, and we replace hydrants and associated components including valves, gaskets, and nozzles once a hydrant is past its service life, generally around 50 years.
Contact us today to schedule an inspection or repair for your property's fire hydrant.

Services
PSI and GPM Flow Testing
Is your property's hydrant overdue for testing? We test the PSI and GPM produced by the fire hydrant on the water main closest to your building, so you know it can deliver the pressure and volume firefighters need if it's ever called on.
Reasons not to delay flow testing:
- Low PSI or GPM often traces back to a partially closed valve you cannot see from the surface
- A hydrant that has not been tested is an unknown, not a known good
- Flow testing also flags leaks and other issues before they become an emergency day problem
Preventative Maintenance and Lubrication
Are your hydrant's caps or stem nuts difficult to turn? Seized hardware is one of the most common reasons a hydrant fails when it is needed most. We flush the hydrant, lubricate all stems, threads, and caps with industrial grade grease, and grease the exterior to guard against corrosion and rust. For more detail on our process, see our guide to fire hydrant maintenance and repair.
Reasons to keep hydrants maintained:
- Seized caps and stem nuts can cost critical minutes during a fire response
- Regular lubrication and greasing prevents corrosion from locking up moving parts
- A hydrant that operates smoothly is less likely to be damaged during use

Fire Hydrant Repair
Is your hydrant leaking, missing a cap, or showing rusted bolts and broken couplings? We repair private fire hydrants across Anne Arundel County to restore full function, replacing valves, gaskets, and nozzles as needed, and we flag anything that needs full replacement rather than patching a hydrant that will fail again. Read our ultimate guide to fire hydrant repair and maintenance for a deeper walkthrough of how we assess a hydrant on site.
Reasons not to delay a hydrant repair:
- A leaking hydrant wastes water and can undermine the surrounding pavement or soil
- Missing caps and exposed threads invite debris, corrosion, and vandalism
- A hydrant that fails during an actual fire is a liability issue, not just a maintenance issue
Fire Hydrant Replacement
Fire hydrants are generally due for replacement after about 50 years of service, and older hydrants can also fall out of step with current parts and fitting standards. We replace aging hydrants and associated components, excavating, setting the new hydrant, backfilling to proper depth over the weep and drain holes, and restoring the site when we're done.
Reasons to replace an aging hydrant:
- A hydrant nearing or past 50 years old is a higher risk for internal failure under pressure
- Older hydrant models can be harder to source parts for when something breaks
- Replacing proactively avoids losing hydrant coverage on the exact day you need it
New Fire Hydrant Installation
Are you developing a new site or adding a building that needs fire protection coverage? Seadmok Water Construction LLC installs new fire hydrants for commercial and multifamily development across Anne Arundel County, tied into a new or existing water main, and sized and placed to meet fire marshal spacing requirements.
Reasons to install a new fire hydrant:
- Fire Marshal review for new construction typically requires hydrant coverage within a set distance of the building
- An undersized or poorly placed hydrant can hold up a certificate of occupancy
- New hydrants installed correctly the first time avoid a costly relocation later
Public Hydrants vs Private Hydrants, Who Maintains What in Anne Arundel County
This is where a lot of property owners get caught off guard. Anne Arundel County's Water Line Maintenance Division, a 30 person team, maintains the public hydrants along the county's roughly 1,200 miles of water main, including painting more than 1,000 hydrants a year and flushing mains through hydrants to clear sediment. It does not maintain the hydrant sitting on your shopping center lot, your apartment complex's fire lane, or your warehouse yard. That one is yours, and it is usually the one an insurance auditor or fire marshal asks about first.
How Seadmok Compares to Other Fire Hydrant Options in Anne Arundel County
Property owners in Anne Arundel County researching fire hydrant service usually run into one of three types of providers, and each leaves a gap Seadmok fills differently.
- Anne Arundel County's own Water Line Maintenance Division only maintains the roughly 1,200 miles of public water main and the public hydrants along it. They have no role in servicing the hydrant on your private property, and calling them about a private hydrant just gets redirected.
- General plumbing companies serving the county, the kind that list hydrant repair alongside drain clearing and water heaters, treat hydrant work as one line item among dozens of trades. We are a utility contractor first, hydrants, water mains, and service connections are the core of what we do every day, not an add on.
- Commercial fire protection companies in the area focus on sprinkler systems, fire alarms, and fire extinguisher inspection. Fire hydrants sit outside that scope for most of them, they will point you elsewhere if your issue is the hydrant itself rather than the building's internal suppression system.
- Seadmok sits in the gap: a licensed Maryland utility contractor whose daily work is water and sewer infrastructure, with fire hydrant PSI and GPM testing, maintenance, repair, and replacement as a standing part of that scope, not a side service.
CASE STUDY: CAPITOL HEIGHTS FIRE HYDRANT REPLACEMENT
Service: Fire Hydrant Replacement
A local business in Capitol Heights, Maryland needed a contractor to replace three aging 6 inch fire hydrants. The property owner consulted multiple firms before choosing Seadmok Water Construction LLC. The site's infrastructure posed unique challenges, but our team executed the replacement with detailed planning and finished the job as scoped.
What we did:
- Conducted careful excavation to remove three old 6" fire hydrants.
- Installed three new 6" fire hydrants.
- Backfilled to a 2 foot depth with Class 57 gravel over the weep and drain holes.
- Stabilized and seeded the area, restoring the landscape.
We have not published an Anne Arundel County specific fire hydrant case study yet, this Capitol Heights job shows the same scope and process we run on private hydrant replacements across our Maryland service area, Anne Arundel County included.
Frequently Asked Questions
Fire hydrants should be tested at least once a year to make sure they are functioning correctly. Properties with heavier occupancy or insurance requirements sometimes test more often.
