Why does my drain clog worse in winter?

Winter weather creates several conditions that make drain clogs more frequent and severe. Cold temperatures, increased indoor activity, and seasonal habits all contribute to more stubborn blockages during Ottawa's long winter months.

Cold temperatures slow down drain flow because grease and soap residue solidify faster in cooler pipes. When you wash dishes with hot water, the grease flows down liquid but quickly hardens as it hits the cold pipes running through unheated basements or exterior walls. This creates a sticky coating that traps food particles, hair, and other debris much more effectively than in warmer months.

Increased indoor cooking and bathing during winter puts extra strain on your plumbing system. Ottawa families spend more time indoors, cooking heavier meals with more grease, taking longer hot showers, and doing more laundry. Kitchen drains see more cooking oils and food waste, while bathroom drains handle increased hair and soap buildup from longer, hotter showers that people take to warm up.

Tree roots become more aggressive in winter as they search for warm water sources. The heated water in your sewer lines becomes an attractive target for roots seeking moisture during Ottawa's dry, cold months. These roots can create partial blockages that worsen throughout the winter season.

Prevention is key during winter months. Run hot water longer after washing dishes, avoid pouring any grease down drains, and consider having your main sewer line inspected before winter if you've had previous issues. Installing drain screens and being mindful of what goes down your drains becomes even more important when cold weather makes clogs harder to clear.
