Plastic drain lines make up most of what runs under a Davie home, unlike the aging cast iron still found in parts of the county’s older housing stock, so a clog here is rarely about the pipe itself failing. It’s almost always about what got sent down it: grease that cooled and set up solid, coffee grounds, stringy scraps from a disposal working overtime, hair tangled with soap residue in a bathroom line. Any of it can settle at a fitting, a trap, or a low spot where flow already slows enough to let debris catch.
One fixture backing up on its own is typically a local problem, contained to that branch line. Several fixtures backing up together, particularly the lowest drain in the house, points to trouble further along toward the main line rather than any single sink or tub, and that difference decides which tool the job actually calls for.
