Common Drainage

Issues We Fix

Drainage problems can cause serious damage if left untreated — from water damage to health hazards. At Plumbing On Site, we’re experts at quickly identifying and resolving these common issues:

Water Pooling Indoors?

Wet floors in your laundry, basement, or garage?
Clogged or overloaded floor drains are common in multi-unit and older homes. We clear the blockage, disinfect the area, and prevent reoccurrence.

Slow Drains or Gurgling?

Your daily rinse shouldn’t feel like a flood.
We clear clogged sinks, tubs, and showers fast — removing hair, grease, and soap scum with advanced snaking and jetting tools.

Water Coming Up Instead of Down?

That’s a red flag for a main line issue.
Our team uses camera inspections and hydro-jetting to locate and clear major sewer line blockages — before they cause serious damage.

Still Not Sure What's Wrong?

Avoid guesswork and costly digging.
We use high-definition cameras to locate cracks, roots, or blockages inside your pipes — giving you a clear plan forward without tearing up your home.

What Type of Drain Problem

Are You Facing?

No matter where you are in the GTA, Plumbing On Site is just a call away when drainage issues start to disrupt your day.

From slow bathroom sinks to full-scale sewer backups, drainage problems come in all forms — and we’ve seen (and fixed) them all. Tap through the sections above to explore the most common issues we resolve, and learn how our licensed technicians tackle each one with speed, precision, and care.

We’re ready 24/7 — whether it’s a mystery smell or a rising flood.

Basement Drain Backups

When stormwater or sewage flows back into your basement, it’s usually a mainline issue or floor drain clog. We provide emergency response and root-cause clearing.

Laundry Room Flooding

Washing machine drains often clog with lint and soap buildup. We clear the trap and test for proper outflow.

Garage & Utility Area Floods

Poor drainage or debris-blocked grates in garages can lead to water pooling — we’ll snake, flush, or regrade as needed.

Slow or Standing Water in Sinks

Grease, food scraps, or soap buildup can block pipes. We use safe snaking and enzyme solutions to restore flow.

Shower & Tub Clogs

Hair and product residue are common in bathroom drains. We clear the pipe thoroughly and recommend preventative options.

Foul Odors from Drains

If you smell sewage or mold, it could be a dry trap or biofilm buildup. We clean and deodorize to eliminate the cause.

Frequent Drain Backups Across Home

If more than one drain backs up, the issue likely lies in the main sewer line. We inspect it with a camera and clear it with hydro-jetting.

Tree Root Intrusion

Roots often grow into older clay pipes. We remove roots and recommend repair or lining for long-term protection.

Collapsed or Cracked Sewer Lines

We locate breaks underground with precision and offer trenchless or traditional replacement options depending on the damage.

Non-Destructive Diagnosis

Avoid tearing out walls or floors. Our inspection cameras identify pipe blockages, root growth, or damage in real time.

Pre-Purchase Drain Checks

Buying a home or property? We inspect underground drainage before you commit — helping you avoid costly surprises later.

Video Proof for Insurance

We provide recorded footage of damage or clogs when needed for insurance claims or landlord/tenant documentation.
