About this drain problem
What can cause this problem?
Kitchen drains commonly collect grease, food residue, and other material. Bathroom sinks, tubs, and showers commonly collect hair, soap residue, and personal-care products. The material involved depends on the fixture and how it is used.
A slow drain often means the opening is narrowing. Water may still disappear eventually, but the restriction can keep catching more material until the fixture drains very slowly or stops. Avoid pouring grease into a kitchen sink; let it cool and dispose of it in the trash instead.
If one sink, tub, or shower is affected while the other fixtures drain normally, the restriction may be close to that fixture or in its branch drain. If several fixtures back up together, or water comes up through a floor drain when a sink or tub is used, the problem may be farther down a shared drain or main line.
A-1 Drain Cleaning clears kitchen and bathroom drain blockages in Mason City and North Iowa. When you call, describe which fixture is slow, whether it is fully stopped, and whether any other drain changes when water is used. Those details help distinguish a local fixture clog from a larger drain-line problem.
Common pipe sizes vary by fixture and installation. The visible drain opening does not reveal the full pipe route or where a blockage sits; the symptoms and affected fixtures provide better clues.
Kitchen and bathroom drain problems can start with a slow sink and progress to a complete backup. If a kitchen sink will not drain, the kitchen drain line may have a local restriction. A bathroom sink that is backing up, a shower that will not drain, or a shower drain that is backing up can also point to a branch-drain problem. When the tub backs up when the washing machine drains, the problem may be farther down a shared line.
Common sink, tub, and shower drain sizes
Kitchen sinks commonly connect to 1½- or 2-inch drain piping. Bathroom sinks often use 1¼- or 1½-inch piping, while tubs and showers commonly use 1½- or 2-inch drains. Actual sizes vary by fixture, age of the plumbing, and local installation. These are typical pipe sizes—not a diagnosis of where a clog is located.
Signs the drain may be involved
- Water pools in the sink or tub
- The shower drains slowly
- The drain stops completely after getting slower over time
