How to Read Your Water Meter and Spot Hidden Leaks
At Murrayville Plumbing, we hear the same concern from homeowners all the time: the water bill crept up and nobody can figure out why. Learning how to read your water meter and spot hidden leaks is one of the most practical things you can do as a homeowner, and it costs nothing but a few minutes of your time. You do not need any tools, any plumbing background, or any prior experience.
Finding Your Water Meter
If you have never located your meter before, you are in good company. Most homeowners go years without ever looking for it.
In the Murrayville area, residential meters are typically found in one of these spots:
- In a covered concrete box near the street or property line
- In the basement, near where the main water line enters the house
- In a crawl space or utility room
Lift the cover carefully and set it aside. The meter itself will be clearly visible once you find the box. If you are having trouble, your municipality’s website will usually have location guidance specific to your neighbourhood.

Understanding What You Are Looking At
Water meters generally fall into one of two types, and each reads a little differently.
Analog (Dial) Meters
These have a series of small clock-like dials arranged in a row. Read them left to right, noting the lower of the two numbers the needle sits between on each dial, similar to reading an odometer. The combined reading gives your cumulative water usage in cubic metres or gallons depending on your utility.
Digital Meters
These display a straight row of numbers, making them simpler to read at a glance. Just note the numbers shown on the display.
The Flow Indicator
Both meter types include a small indicator, often a triangle, star, or spinning wheel, that moves whenever water is flowing anywhere in your system. This is the most important element for leak detection. Even a very slow, steady flow will keep that indicator moving.

The At-Home Leak Test
This is the part that makes a real difference. The process is straightforward, and it will give you a clear answer.
- Turn off every water-using fixture and appliance in the house. This includes toilets, taps, the dishwasher, washing machine, ice maker, and any outdoor irrigation.
- Check your meter. Write down the reading, or simply watch the flow indicator for 30 to 60 seconds.
- If the flow indicator is already moving with everything off, water is actively going somewhere it should not be.
- If the indicator is still, wait one to two hours without using any water in the house.
- Check the meter again. If the reading has changed, you have a leak somewhere in the system.
A reading that stays identical confirms no leak is present. A reading that changed, even slightly, tells you water is leaving the system.
Common Places Leaks Hide
Once your meter confirms a leak, the next step is narrowing down the source. These are the spots worth checking first:
- Toilets: A worn flapper valve is the single most common cause of hidden water loss. Add a few drops of food colouring to the tank and wait 15 minutes without flushing. If colour appears in the bowl, the flapper is leaking.
- Faucets: A slow, steady drip at any tap adds up meaningfully over weeks and months.
- Water heater: Check around the base of the unit for moisture, rust staining, or pooling.
- Washing machine hoses: Inspect the connections at the back of the machine for any sign of weeping or mineral buildup.
- Refrigerator ice maker line: Follow the supply line behind the fridge and check where it connects to the wall valve.
- Underground pipes: If you cannot locate a source inside the house, look outside for unexplained wet patches in the yard or areas where the grass is noticeably greener than the surrounding lawn.
Knowing When to Call
Some leaks are straightforward fixes: a new flapper, a tightened connection, a replaced washer. Others are not, and there is no shame in recognizing where the line falls between a confident DIY repair and a job that needs a professional.
Call sooner rather than later if:
- Your meter confirms a leak but you cannot locate the source anywhere in the house
- Water is actively flowing or causing visible damage
- The suspected leak is inside a wall, under a slab, or underground
- You find the source but are not comfortable making the repair yourself
Catching a problem early almost always means a simpler, less costly fix. Waiting to see if it resolves on its own tends to turn a small repair into a much bigger one.
