Plumbing emergencies rarely happen at a convenient time, and the first few minutes matter. Whether it's a burst pipe in the middle of the night or a toilet that won't stop overflowing, knowing what to do (and what not to do) can be the difference between a quick cleanup and thousands of dollars in water damage. Here's our guide for staying calm and minimizing damage while you wait for help.
Your first move should always be to stop the source. Every home has a main water shut-off valve, usually near where the water line enters the house, in a basement, utility room, or near the water meter. If you're not sure where yours is, take a few minutes today to find it; during an emergency is not the time to be searching. For an isolated issue, like an overflowing toilet, you can often shut off the smaller valve located directly behind or beneath the fixture.
Rural properties around Keswick, Georgina, King City, Stouffville, Bradford, East Gwillimbury and the edges of Holland Landing are often on private wells, so there is no municipal shut-off. Water comes from the well pump into a pressure tank, usually in the basement or utility room. Close the valve on the house side of the pressure tank; if you can't find it or it won't turn, switch off the breaker labelled well pump or pump. The pressure tank keeps pushing out the water it holds until its pressure drops, so expect some flow to continue briefly.
If the burst is on a line below the tank, the tank can drain out through it. Set a gas heater to Pilot or Vacation and switch an electric heater off at its breaker so an element does not run dry.
Water and electricity are a dangerous combination. If flooding is approaching outlets, electrical panels, or appliances, shut off power to that area at the breaker, but only if you can do so safely without stepping into water.
Use towels, buckets, and any waterproof containers to limit how far the water spreads. Move furniture, electronics, and valuables out of the affected area if it's safe to do so. Every minute counts when it comes to preventing damage to flooring, drywall, and belongings.
It's tempting to grab tools and attempt a repair, but in an emergency situation this can often make things worse, especially with pressurized lines or sewage backups. Stick to shutting off water and limiting the spread; leave the diagnosis and repair to a licensed professional.
Water rising from a basement floor drain or the lowest toilet usually means a main line blockage or a sewer line problem. Every flush, shower and laundry load upstairs adds to it. Stop all water use, stay out of the water (it is sewage), and call. Once it is cleared, ask us about municipal subsidy programs for a backwater valve.
If you can reach the plug from dry floor, unplug the pump before touching anything in the pit. Check the float is not jammed against the pit wall and the breaker has not tripped, then plug it back in. If the pit is rising and the pump is quiet, call; a battery backup is the fix for next time.
Leave the main off and do not thaw it with a torch; the split will spray as soon as it thaws. Burst pipe repair usually means cutting out and replacing the split section. Our guide to preventing frozen pipes in York Region covers what to do before winter.
The plumber confirms the water is isolated, finds the actual failure (often not where the water is showing), makes it safe, and gives you a written price for the permanent repair before doing it. If a part has to be ordered you will know what the temporary fix is and when we are back. We cover Keswick, Georgina, Holland Landing, Newmarket, Aurora, Richmond Hill, Vaughan, Markham and the other towns in our service area with 24/7 emergency plumbing.
