When the kitchen sink clogs once, it could just be an accident. But when the blockage happens repeatedly, it's a sign that there's a deeper problem in the plumbing. In addition to the daily inconvenience, recurring blockages can cause bad smells, dirty water returning and even damage to the pipes.<\/p>\n

If you need professional help Lisbon Plumber company<\/a> is the best solution for eliminating blockages safely and permanently.<\/p>\n

Why do clogs in the kitchen keep reoccurring?<\/h2>\n

A recurring blockage is rarely caused by a single factor. It is usually the result of daily habits combined with problems in the installation itself.<\/p>\n

1. Constant accumulation of fat<\/h3>\n

Grease is the main cause of blockages in the kitchen. Even when poured hot, it solidifies inside the pipes, forming layers that reduce the diameter of the pipe and facilitate new blockages.<\/p>\n

2. Leftover food in the drain<\/h3>\n

Rice, pasta, shells, ground coffee and small debris accumulate in the siphon and pipes, creating frequent blockages.<\/p>\n

3. Excessive use of detergents<\/h3>\n

Detergents combined with grease form a kind of paste that sticks to the walls of the pipes, aggravating the blockage over time.<\/p>\n

4. Incorrectly installed or damaged siphon<\/h3>\n

A poorly fitted or defective siphon can trap debris and hinder drainage, causing repeated blockages.<\/p>\n

5. Incorrect pipe inclination<\/h3>\n

If the pipe isn't inclined enough, the water won't drag the waste away properly, making it easier for it to accumulate.<\/p>\n

6. Old or corroded pipes<\/h3>\n

Old pipes, especially iron ones, create uneven surfaces on the inside, where debris sticks more easily.<\/p>\n

7. Blockage in the main sewage line<\/h3>\n

Sometimes the problem isn't just in the sink, but further down the sewage system in the house or building, causing the blockage to reappear after each superficial unclogging.<\/p>\n
