Your water service line and supply-side plumbing are the backbone of the entire system. When pressure is low, valves don’t work, or the line is aging, the symptoms show up everywhere—showers, laundry, appliances, and fixtures. Tornado Plumbing & Drains provides water service upgrades, main water line repairs, shut‑off valve work, pressure regulation, and outdoor tap solutions across Toronto & the GTA. We focus on reliability, clean installation, and making sure shut‑offs and key components are accessible when you need them. If you suspect an underground leak or you’re planning renovations, addressing supply-side weaknesses early can prevent larger failures later.
