Spring is a practical time to check bathroom plumbing because small leaks, worn seals, and ventilation problems are easier to correct before they damage finishes or create mould-friendly moisture.
Start with a leak check
Look under sinks, around supply valves, at the toilet base, and beneath the tub access panel if one exists. Watch for damp cabinet floors, corrosion, staining, soft caulking, or a toilet that runs between flushes. Do not ignore intermittent moisture; photograph it and note when it appears.
Test drainage and fixtures
Slow drains may respond to removing hair from an accessible stopper. Avoid mixing drain-cleaning products. Check that faucets shut off cleanly, the showerhead is not spraying behind the surround, and the toilet is stable. A rocking toilet or leak at the base needs professional attention.
Improve water efficiency
If a fixture is due for replacement, compare certified water-saving toilets, showerheads, and faucets. Choose parts that fit the existing plumbing and maintain comfortable pressure. Replacing a worn aerator or showerhead is often a simpler upgrade than a full remodel.
Control bathroom moisture
Run the exhaust fan during bathing and long enough afterward to clear humidity. Clean the grille and confirm the fan vents outdoors. Repair failed caulk only after the area is clean and fully dry; caulk is not a substitute for fixing a leak behind the wall.
Know when to call a licensed plumber
Call for help with hidden leaks, recurring clogs, sewer odours, low pressure affecting several fixtures, pipe movement, water damage, or any work that requires opening walls or changing supply and drain lines. Confirm local permit requirements before a renovation.
