The Gravity Difference

Water restored. Repaired without delay.

A small leak in your water main today is a burst line tomorrow. Water mains corrode over time due to age, soil movement or temperature changes, leading to persistent leaks, ruptures and reduced water pressure. Our team diagnoses and repairs underground water supply lines, addressing leakage, cracks, corrosion and discontinuities before they cause structural damage.

If you notice low water pressure, unexplained puddles in your yard, or a sudden increase in your utility bills, turn off your water supply and call us right away rather than attempting a DIY repair.

Original galvanized steel water mains are still common in older pockets of Vancouver and New Westminster, and their internal corrosion is one of the most frequent causes of the low pressure and rusty water we get called out for in those neighbourhoods.

Yes, our emergency plumbing team can be engaged for urgent water main fixes any time, day or night.

Water mains are often damaged by corrosion, soil movement and tree root intrusion.

A frozen line can often be repaired professionally using pipe repair methods, but in extreme cases a full replacement may be needed.

An average main water line replacement takes one to three days, depending on the complexity of the job.

The municipal utility typically owns the main under the street, while the homeowner is responsible for the service line running from that main into the house — we can help clarify where the line falls if you're unsure.
