What we run into most

Real-World Plumbing Issues We Repair Fast

We've seen every issue a routine plumbing check can uncover. Here are the problems our clients call us about most often.
💧

Water Pressure Dropping Slowly

Gradually dropping pressure at one or more fixtures usually points to mineral buildup narrowing the pipe from the inside rather than a supply issue. Left unaddressed, the buildup keeps accumulating and pressure keeps dropping across the home. We inspect the affected lines and clear or repair the restriction.

🚿

Slow Draining Sink or Tub

A drain that never fully clears even after DIY attempts usually has buildup further down the line than a plunger or drain cleaner can reach. Left alone, the clog often worsens until the drain backs up completely. We clear the line mechanically and check the trap for a proper seal.

🔥

Water Heater Making Popping Noises

Popping or rumbling sounds from a water heater almost always mean sediment has built up at the bottom of the tank, insulating the burner from the water above it. Left untreated, this reduces efficiency and can shorten the tank's working life significantly. We flush the sediment and check the anode rod during every visit.

🔧

Shutoff Valve Won't Turn

A valve that has not been used in years often seizes in place from mineral deposits and corrosion around the stem. This becomes a serious problem the one time a homeowner actually needs to shut off water fast during an emergency. We test and service every accessible valve as part of a full maintenance visit.

📈

Unexplained Increase in Water Bill

A rising water bill with no clear change in household usage often points to a small hidden leak somewhere in the system. Left unchecked, even a slow leak adds up to significant wasted water and cost over months. We check every fixture and accessible pipe run to find the source.

🟤

Discolored Water From the Tap

Rusty or discolored water, especially right after the home sits unused, usually points to corrosion inside older galvanized piping. Left ignored, internal corrosion continues narrowing the pipe until it eventually fails. We assess the affected lines and recommend the right next step.

🚽

Toilet Running Constantly

A toilet that runs after every flush usually has a fill valve or flapper that no longer seals completely. This wastes a significant amount of water without the sound always being obvious to the homeowner. We inspect and adjust or replace the internal components as needed.

🏠

Never Had Plumbing Professionally Checked

A home that has never had a professional plumbing inspection is usually carrying more hidden wear than is visible at a glance. Catching corrosion, worn seals, or sediment buildup early prevents a larger, more expensive repair later. We assess the entire home thoroughly during the first visit.

❄️

Outdoor Hose Bib Cracked From Winter

A hose bib that was not properly protected during a hard freeze often develops a hidden crack that only becomes obvious once it is used again in warmer weather. Left unnoticed, the crack can leak inside a wall cavity every time the bib is turned on. We check outdoor fixtures as part of every seasonal maintenance visit.

Karen L.

Found a valve that would not have shut off

The technician from Core Ontario Plumbing Services tested every shutoff valve in our house and found two that were completely seized. We had no idea until he showed us. Glad it got fixed before we ever needed it in an emergency.

Water heater is running so much better now

Our water heater was almost 9 years old and had never been flushed. After the sediment flush and anode rod check, the hot water recovers noticeably faster. Wish we had booked this years ago.

Thorough visit, took a bit longer than quoted

We have an older home with a lot of original piping so the visit ran closer to two and a half hours instead of the estimated two. Worth it though since they found a slow leak under the kitchen sink we never noticed.

Honest about what actually needed attention

I expected to be told everything needed fixing but the technician was upfront that most of our plumbing was in good shape. Core Ontario Plumbing Services only flagged two small items and gave us a written summary for the rest.

Priya S.

Caught corrosion before it became a problem

One of our supply lines had visible corrosion starting that we would never have noticed on our own. The team explained exactly what was happening and replaced it the same day. Really appreciated the clear explanation.

Booking was simple and the technician arrived right on time. He walked through every fixture in the house and explained what he was checking as he went. Core Ontario Plumbing Services made the whole process easy to follow.
