Before calling a plumber for a leak, there are three things you can do at home that take 20 minutes total and often reveal exactly what’s going on. We’ve coached Everett homeowners through these on the phone enough times that we figured it was worth writing them down.
The Three DIY Methods That Actually Work
Method one: the meter test. Turn off every water-using fixture and appliance in the house. Read your water meter (the digital display or the dial). Wait 30 minutes without using any water. Read again. If the number moved, you have a leak somewhere in the supply system. If it didn’t move, the leak is downstream of a shutoff (toilet, fixture, or supply line that’s currently off). The meter test takes 30 minutes and tells you whether you’re chasing a supply leak or a fixture leak.
Method two: the food coloring test for toilets. Drop 10 drops of food coloring (or a dye tablet) into the toilet tank. Don’t flush. Wait 20 minutes. If the coloring appears in the bowl, the flapper or flush valve is leaking. This is one of the most common hidden leaks in Everett homes — a slow-leaking toilet can waste 200+ gallons per day without making any obvious noise. We see it on water bills before homeowners see it in the bathroom.
Method three: visual + audio inspection. Walk every fixture, every visible pipe, the water heater area, and the laundry connections. Look for water staining, mineral deposits (white crusty buildup), discoloration on ceilings or walls. Listen at the main shutoff valve with the house quiet — a hissing sound when no water is in use means there’s a leak somewhere downstream of the meter. Our piece on why water bills spike unexpectedly covers the secondary signals when the leak isn’t visible yet.
When DIY Isn’t Enough
If the meter test showed movement but you can’t find the leak visually, it’s hidden. Hidden leaks in Everett homes are typically in one of three locations: behind a wall, under a slab, or in the buried supply line between the meter and the house. Each requires a different professional tool to locate without tearing up drywall or yard.
Behind-wall leaks: thermal imaging is the first tool. A pipe leak changes the local wall temperature in a pattern that thermal cameras can read clearly. Acoustic listening devices work on pressurized lines that are actively leaking — the pressure release creates sound at frequencies the device amplifies. Under-slab leaks: pressure testing and acoustic combined, usually. For buried supply line leaks (the version that often shows up as a wet spot in the yard or a sudden water bill spike), our underground water leak signs covers what to look for before calling.
What We Use on Service Calls
For an Everett home with a suspected hidden leak, we typically arrive with four tools. A pressure gauge that lets us isolate sections of the supply system to narrow down where the leak is. A thermal imaging camera for wall and ceiling diagnostics. An acoustic leak detector for active pressurized leaks. And a smoke testing kit for venting and drain line leaks (different problem, different tool). The whole diagnostic process usually takes 60–90 minutes; the goal is to identify the leak location precisely enough that the repair opens up the smallest possible section of wall or floor.
The diagnosis-first approach matters more than the repair itself. We’ve been called as the third opinion on Everett homes where two previous plumbers had cut holes in walls based on guesses. Don’t let anyone open up your house without locating the leak first. Our non-invasive leak detection team handles the diagnostic; the repair quote comes after we know what we’re actually fixing. Or reach our team of Everett plumbers directly if you’d rather schedule by phone.
