Slow Kitchen Sink in Port Arthur: Grease Buildup or Something Flooding Left Behind

Start with the same test regardless of what you suspect caused it. Run the tub, flush a toilet, or turn on another sink while the slow one drains. If everything else moves normally, the blockage sits in that fixture's own trap or the first few feet of pipe past it. This matters more in Port Arthur than in most cities, because homes here have a real history of sewer backups from overwhelmed systems during major storms. A single slow sink is a different, much smaller problem than that, and it is worth being clear about which one you are looking at before assuming the worst.

A large share of Port Arthur's housing went up during the refinery build-out years, and the kitchen plumbing in those homes is frequently original or close to it. Older branch lines, whether cast iron or early galvanized fittings, have less interior room than they did when installed, simply from age. A slow sink in one of these houses often has an ordinary cause, grease and food narrowing an already-reduced opening. The age of the house explains why the same amount of buildup causes a slower drain here than it would in a newer branch line elsewhere.

On a house that flooded during Harvey or Imelda, low branch lines took on water along with everything else in the building. Fine silt in that water settles inside pipe just as it settles anywhere else, and it does not flush out with normal dishwashing and cooking use the way grease eventually can be managed. The way to tell the two apart without opening anything is history and texture. A drain that slowed down gradually over ordinary use is grease. A drain that has never fully recovered since a specific flood event, or that produces gritty, sandy residue rather than greasy residue when snaked, is more likely carrying flood silt that settled and stayed.
