There’s a lot to love about living in Ontario—sunshine, great neighbors, and peaceful streets. But let’s be real: even in a quiet neighborhood, plumbing issues can hit fast and hit hard. Whether it’s a sneaky leak raising your water bill or a backed-up drain that ruins your weekend, small problems have a way of turning into big messes.
At Royalty Plumbing and Drain, we’ve seen it all. From tiny hiccups that snowball into water damage, to well-meaning homeowners who waited just a bit too long to pick up the phone. That’s why we’re laying out the top 7 signs you need a plumber right now, plus what to do before things get out of hand.
1. Your Sink or Toilet Is Making Gurgling Sounds
Ever hear your kitchen sink make a weird burping sound when your washing machine is draining? Or catch your toilet bubbling when nobody’s around? That’s not your house messing with you—it’s your plumbing system gasping for air.
Gurgling is usually the first sign that a blockage is starting to form in your pipes or vent stack. Air gets trapped, and instead of flowing smoothly, your plumbing starts sounding like it’s alive.
What to do first: Stop using water-heavy appliances, and don’t wait—call a licensed local plumber to check it out.
“We had a client off Vineyard Avenue who thought it was hard water causing the toilet noise. A quick camera inspection showed tree roots had taken over her main line. We cleared it before it became a full-on disaster.” – Royalty Plumbing & Drain Crew
2. The Water Pressure Drops All of a Sudden
If the water pressure in your house tanks out of nowhere, don’t brush it off. It could be something simple, or it could be something serious—like an underground leak, corroded pipes, or mineral buildup in your lines.
In older Ontario neighborhoods like Armsley Square, hard water buildup is a known issue. Over time, mineral deposits coat the inside of pipes, leaving less room for water to move.
What to do first: Check whether it’s just one faucet or the whole house. If the pressure drop is everywhere, don’t guess—get it looked at right away.
3. That Water Bill Just Shot Up Without Warning
When your bill spikes and your habits haven’t changed, you’ve probably got a leak somewhere—and not the kind that makes noise. Toilets can leak silently, faucets can drip unnoticed, and slab leaks can run up thousands of gallons per month without you even realizing it.
What to do first: Shut everything off and check your water meter. Wait a couple hours without using any water, then check again. If the numbers moved, something’s leaking.
4. Your Drains Are Sluggish and Backing Up
One slow drain? Probably just a small clog. But if every sink and tub in the house is slow, there’s a deeper problem—usually in your main sewer line. This is especially common in older homes with cast iron pipes, which can corrode and close in over time.
What to do first: Try a plunger or a safe, natural drain cleaner (skip the chemicals). Still slow? Call us before things get messy.
5. Something Smells... Off
If you’re walking into your bathroom and catching a whiff of something rotten, don’t ignore it. That sewer-y, sulfur-like smell could be coming from a cracked sewer line, a dried-out P-trap, or a clogged vent stack.
Whatever it is, it’s not just gross—it can also be a health risk.
What to do first: Run water in all your sinks and flush the toilets to fill the traps. If the smell sticks around, you’ve got a deeper issue.
6. Your Ceiling or Walls Are Stained or Growing Mold
Got a strange brown spot on the ceiling or mildew crawling up the wall? You’re probably looking at a leak that’s been hanging around for a while. This is especially common in multi-level homes and condos, where upstairs plumbing leaks make their mark downstairs.
“We had a call from a homeowner in Creekside who noticed a dark patch in her closet ceiling. Turns out the upstairs tub had a cracked drain seal. We fixed it before it got moldy.”
What to do first: Don’t keep using any plumbing in that area—book a leak check before water damage spreads.
7. Pipes That Bang, Knock, or Shake
If you’re hearing banging or knocking when you shut off the tap, you might have what plumbers call a “water hammer.” It happens when water moving at full speed suddenly stops or changes direction, and it can put real stress on your plumbing.
What to do first: Turn off your water supply to be safe, then call in a pro. We’ll install air chambers or a pressure reducer to quiet things down and keep your pipes safe.
Bonus: You Just Moved into a New Home in Ontario
New home? Don’t let the fresh paint fool you. Even homes that look great can have aging water heaters, patched-up pipes, or DIY “fixes” hiding behind the drywall. A quick inspection can save you a lot of trouble.
Why Plumbing Problems in Ontario, CA Are a Bit Unique
Here’s what makes our region a little tricky when it comes to plumbing:
Hard Water – Ontario’s water is mineral-heavy, which leads to buildup in pipes and appliances.
Tree Roots – Mature trees are beautiful, but their roots love breaking into sewer lines.
Old Infrastructure – In spots like Rosewood Court and Ontario Ranch, many homes still have original piping that’s well past its prime.
That’s why it matters to hire a plumber who actually knows Ontario. We’ve been here long enough to know which issues are common, what to look for, and how to fix it fast.
