How a bungalow is plumbed
The classic Mississauga bungalow from the 1950s and 1960s, the kind lining streets in Lakeview, Applewood, Clarkson and Port Credit, keeps its kitchen and single bathroom on the main floor directly above an open or partly finished basement. A single cast-iron stack drops through the house, picks up the bathroom group and kitchen sink, and turns into a horizontal drain that runs under the basement slab toward the front wall. There it leaves the house as a lateral, often clay tile in the original build, and heads to the municipal sewer under the road.
The faults we meet
- Root intrusion in clay lateral joints, especially under maples planted when the street was new
- Scaled and cracked cast iron under the slab, which shows up as slow floor drains and a smell in the laundry corner
- Gate valves at the main that turn a quarter of the way and stop
- Galvanized nipples left behind from an old repipe, choking pressure at one fixture
- Laundry tubs tied into the floor drain with a hose and a prayer
How we work on one
Because everything collects in the basement, bungalows are honest houses to diagnose. We open the main cleanout, run a cable through to the street and follow it with a camera, which usually tells us within the hour whether a slow drain is a grease plug, a root mass or a broken pipe. Supply work is just as accessible: the joists are open in most unfinished basements, so cutting out failed copper or replacing a seized main valve rarely means touching drywall.
When a basement gets finished
Owners who drywall the basement often bury the very pipes we need. Before the ceiling goes up, have the lateral scoped, swap the main gate valve for a quarter-turn ball valve, and consider fitting a backwater valve, since the slab is being disturbed regardless. Mississauga has run flood-protection subsidy programs before; confirm today's rules with the City first.

Answers our Mississauga crew gives most
Why does my bungalow floor drain smell?
Usually the trap seal has dried out; pour a litre of water in it. If the smell persists, the line under the slab may be cracked and is worth a camera run.
Is the original cast-iron stack still good?
Many still work fine above the floor. Look for rust weeping at joints and for horizontal runs that have scaled shut inside.
