Clogged drains in older homes are a common problem that can be caused by various factors, including mineral buildup, grease and soap scum accumulation, and improper installation of fixtures. The most likely causes include:
- Mineral buildup: Hard water can cause lime scale to form inside the pipes, leading to clogged drains.
- Grease and soap scum accumulation: These substances can solidify in the pipes, causing blockages and reducing water flow.
- Ineffective or poorly installed fixtures: Over-tightened washers or improper installation of sink basins can cause hair and debris to accumulate in the pipes.
