Expert Water Main Repair in the GTA

Who Needs Water Main Repair?

A damaged water main requires prompt attention to prevent property flooding, foundation damage, and total loss of water supply.

‍Galaxy Plumbing provides water main repair for:

Homeowners experiencing a sudden loss of water pressure or no water flow to the property
Property owners who notice unexplained wet patches, sinkholes, or unusually green lawn sections above the water main path
Businesses and commercial operators whose water supply has been disrupted by a main line failure
Multi-unit residential building managers dealing with water main leaks affecting multiple units
Homeowners whose older lead, galvanised steel, or Poly-B water mains have failed or corroded through

What Does Water Main Repair Include?

Galaxy Plumbing provides a complete water main repair service from fault location through to connection restoration:

Water main leak detection using pressure testing, acoustic listening equipment, or ground-penetrating survey to pinpoint the failure
Excavation of the failure zone only, minimising surface disruption
Removal of the damaged pipe section and inspection of adjacent pipe for additional deterioration
Installation of new pipe segment using copper, HDPE, or PVC depending on the existing material and local code
Joint sealing and pressure testing of the repaired section before backfill
Shut-off valve inspection and replacement where the main valve is found to be non-functional
Trench backfill and surface restoration
Permit documentation and inspection support where required by the Ontario Building Code

How Does the Water Main Repair Process Work?

Galaxy Plumbing follows a methodical process for every water main repair to minimise downtime and ensure a durable result:

Fault Location

We use pressure testing and acoustic leak detection equipment to locate the exact failure point without opening unnecessary ground area.

Municipal Notification

Where the failure is near the curb stop or municipal connection, we notify the local utility and coordinate the water shutoff.

Targeted Excavation

We excavate the failure zone only, cutting to the damaged section and inspecting the surrounding pipe for additional deterioration.

Pipe Repair or Section Replacement

Depending on the failure type, we repair the joint or coupling, or cut out and replace the damaged section with new pipe in a matching or upgraded material.

Pressure Testing

The repaired section is pressure-tested before backfill to confirm a leak-free result.

Backfill and Surface Restoration

The trench is backfilled, compacted, and the surface is restored. Driveway or concrete cutting and patching is completed where required.

What Are the Warning Signs of a Water Main Problem?

Identifying a water main problem early limits damage and repair cost. The table below outlines the most common symptoms and what each typically indicates.

Symptom	Likely Cause	Urgency
Sudden drop in water pressure throughout property	Main line break or severe leak	Immediate
No water supply to property	Main line failure or municipal shutoff	Immediate
Wet or sunken lawn above water main path	Slow leak or pinhole failure	High
Discoloured or rusty water at all fixtures	Corroded main line interior	High
Unusually high water bill with no change in use	Slow underground leak	Moderate
Recurring low pressure despite no visible leaks	Partial blockage or internal corrosion	Moderate

For properties where the failure location is not visually obvious, Galaxy Plumbing uses water leak detection equipment to pinpoint the fault before any ground is opened.

It's all love, baby.

We love what we do.
It's pretty much all because of you.

Nancy Pascua ★★★★★

Just fantastic service. Spent extra time trying to figure out a mysterious water leak. Super professional and knowledgeable. Gave me options and time to decide how to proceed. Would use again and would recommend to anyone.

Bev Battaglia ★★★★★

Fantastic job by Galaxy Plumbing! Appreciated the professionalism and informative service from this team. I had a toilet and sink back up issue which the technician was able to come and resolve the same day I called. At the same time, recommendations were shared to prevent similar issues in the future. Great attitude and top notch workmanship!

Jason Lobo ★★★★★

Rob's service from start to finish was exceptional. Spoke with him about getting a dripping bathtub faucet fixed. Walked me through how to remove the valve cover. Also correctly guesses that it was a water cartridge issue. Booked a plumber the next day and sent me a text with the ETA. The communication through out was fantastic. For some one who has never booked a plumber for a smaller job, understand that it's not cheap. And you have to consider the cost of parts if not covered under warranty. Would definitely recommend Rob and use his company again if needed.
