Services

Comprehensive Inspection of Water Mains and Water Valves

Not sure whether your line needs a repair or a full replacement? We assess the main and valves with pressure testing and locate weak joints, leaks, and corrosion before they become a main break.

Reasons not to delay an inspection:

An inspection costs far less than an emergency main break repair
Early detection extends the service life of your mains and valves
Catching a small leak now saves money and water over the long run

Repair of Damaged Water Mains and Water Valves

Have a cracked main, a failing gate valve, or a main break? We repair the line and valves, often using a tapping sleeve and valve so we can work without shutting down the whole system. Because fire hydrants tee off the main, we also handle fire hydrant preventive maintenance when a repair affects the hydrant line.

Reasons not to delay a repair:

A leaking main causes water damage and undermines pavement and foundations
Cracked pipe and corroded valves allow contamination into the supply
A small fault left alone can escalate into a full main break and liability

Replacement of Aging Water Mains and Water Valves

Is your main old cast iron or galvanized pipe nearing the end of its life? We replace failing mains and valves with new ductile iron pipe and modern valves, restoring pressure and reliability.

Reasons to replace an aging main or valve:

Aging pipe sharply increases the risk of a major water main break
Corroded mains raise the risk of water contamination
Deteriorated lines lose pressure across the building or site

Installation of Water Service Connection

Need to connect a property to the municipal supply? We install water service connections from the main to the meter, and this pairs naturally with a full water house connection for the property side of the line.

Reasons to install a new water service connection:

An old or corroded service line restricts flow and risks failure
An undersized connection cannot meet the demand of a new build or expansion
Your local water utility may require a new connection before occupancy
