Kitchen sink
A slow kitchen sink can come down to one stubborn trap or a section of pipe under the cabinet, where grease and food scraps build up. The plumber clears the blockage and checks that the water runs freely afterward.
A drain that is slow, gurgling or backing up can be one fixture’s trap or the line behind several of them. Call and describe which drains are affected, and the plumber you talk to gives a free estimate from there.
This page goes through the drains in a house, one by one, and then the outside cleanout that Irving’s water utility says belongs to the owner to maintain.

A slow kitchen sink can come down to one stubborn trap or a section of pipe under the cabinet, where grease and food scraps build up. The plumber clears the blockage and checks that the water runs freely afterward.
Tubs and showers slow down when hair and soap collect in the trap and the pipe below it. Clearing the blockage at the fixture restores the flow, and a drain that slows again soon after points further down the line.
The washer empties a tub of water in a rush, and a standpipe or floor drain with a partial clog backs up onto the laundry room floor. The plumber works the line from the standpipe or the drain opening.
Two fixtures slowing at once, or a toilet bubbling when the shower drains, put the trouble in the main sewer line. A cable or camera sent through the cleanout locates the blockage and clears it.
Irving Water Utilities’ FAQ says it is the property owner’s responsibility to maintain the cleanout. It describes the outside cleanout as a white square plastic cap sitting about 4 inches above the ground.
A plumber working a cable or camera down the main line goes in through that cleanout, which is why it matters that it is kept in good order.
Grease poured down a kitchen sink hardens in the pipe, and wipes sold as flushable do not break down like toilet paper. Keeping both out of the drain, and putting a hair catcher in the shower, slows the build-up.
