Common Leaks to Look For

Some leaks are more common than others and can go unnoticed for longer than you would expect. To minimize the risk of ongoing leaks causing ongoing damage, we advise you to periodically inspect for:

Drain Leaks

Drain Leaks

Bathtub, shower, and sink drain leaks keep plumbers employed.

While water damage in the ceiling will usually be fairly obvious, we advise you to check underneath your sinks from time to time. Make sure to run water while observing, so you can catch a leak in the act!

Water Heater Leak

Water Heater Leaks

Traditional Hot Water Tanks store large amounts of water with varying temperatures. The heat and pressure that builds up can decay seals and prompt leaks.

Periodically inspect the hot water tank and the surrounding area, checking the tank’s pressure relief valve, as this is the most common water heater leak source.

Dishwasher Leak

Dishwasher Leaks

Dishwashers are more complex than most plumbing appliances, and several things can cause a leak. Always keep an eye out for puddling around the dishwasher, but also periodically check in the basement under the dishwasher while it’s running. Catching a dishwasher leak early is the key to preventing mould.

Toilet Leak

Toilet Leaks

Toilets can leak from multiple places, such as the valve, the bowl, and the drain. A pool of water around the toilet is a sure sign that you have a leak, but keep an eye out for water damage and leaking from lower floors as well!

Leaky Faucet

Leaky Faucets

While a leaking faucet is usually safer than most other leaks because of the sink drain underneath, it’s advisable to take care of it sooner than later as any leak is wasteful and expensive over time. Furthermore, faucets can leak at the hose connections, so remember to check under the sink from time to time!

Leaking Drain Pipes

Drain pipes can leak for various reasons, such as loose or worn compression nuts, incorrectly fitted pipes, damaged pipes, water pressure, lousy leak patches, and several other possibilities. While less consistent and pressurized than waterline leaks, drain leaks are used and dirty water, which can be hazardous.

Water Supply Leaks

Water supply lines have to deal with constant water pressure and varying water temperatures. Combine this with age, corrosion, or poor plumbing fittings, and you’ll eventually have a water supply leak. These leaks often appear behind drywall, in the ceiling, in floors, and basements.

Burst Pipe or Frozen Pipes

Burst Pipes or Frozen Pipes

Unlike most substances, water expands when it freezes. As a result, your pipes are susceptible to bending, damage, and bursting during the cold winter months. We Canadians are no strangers to cold winters!

Properly winterizing your home and plumbing system can save you tons of trouble and money! But we’re here when you need us!

What to do when you notice a leak?

When you notice signs of a leak, it’s important to act fast!

Remember to:

  1. Turn off water in your home.
  2. Take pictures and document the damage.
  3. Identify the source of the leak.
  4. Repair the leak yourself or call John The Plumber!

Signs that you may have a hidden leak?

While some leaks are obvious, others can go unnoticed for months.

Always keep an eye or ear out for:

  1. Unusual noises when using water.
  2. Sagging or water-stained ceilings.
  3. Damaged flooring.
  4. Mold and Mildew.
  5. A noticeable reduction in water pressure.
  6. Increased water usage.

Will a leak repair cause damage to my walls and flooring?

At John The Plumber Kanata and Ottawa, we use advanced plumbing technology and techniques to repair leaks in difficult-to-reach places. We can identify leaks behind walls or in ceilings, which allows us to repair leaks with minimal damage to your home. Unfortunately, sometimes a bit of drywall needs to be removed to reach a pipe, but you might be surprised at how small a hole is required!


More often than not, a leaking drain pipe or water pipe can be repaired, or a small section of pipe can be replaced. But if your plumbing system is old and worn, we may advise that it’s time to consider re-piping your plumbing system.

At John The Plumber, we know that this is daunting, and we don’t say it lightly. We will always try and find the best solution that fits your budget, but we’ll always be honest with our recommendations. If we suspect that your plumbing system is likely to fault, again and again, we may offer to replace your plumbing system with new pipes.

The good news is that the pipes used today last longer or indefinitely and will usually outlive us!

5 Tips on Plumbing Leak Detection

  1. Know the location of your home’s main water shut-off valve! We advise that you share this information with your family so that they can act in your absence!
  2. Locate shut-off valves for individual fixtures and appliances and consider adding shut-off valves where they should be.
  3. Consider installing a flow sensor or a leak detector. These devices can help prevent a leak from turning into a catastrophic basement flood!
  4. Don’t overstuff cabinets with pipes. Crammed sink cabinets and vanities will block your visibility of potential leaks and risk loosening connections when the lines inevitably get bumped.

Have a plumbing inspection done once in a while by a licensed plumber. Plumbers are trained to identify leaks and potential problems before they happen.
