- Frequent causes include:
- Fat, oil and grease buildup
- Wet wipes and sanitary products
- Tree root intrusion
- Collapsed or fractured pipes
- Poor installation
- Heavy rainfall and groundwater pressure
- Structural movement

Top 10 Common Drainage Problems & How To Diagnose Them
Most common drainage problems are caused by a combination of negligence, wear-and-tear and incorrect installation. Property owners often miss early warning signs because drainage systems are out of sight, making regular inspections essential.
1. Slow-Draining Sinks & Baths
Often caused by grease, soap scum or hair buildup. Check U-bends and trap sections first.
2. Gurgling Noises in Pipes
A classic sign of trapped air or partial blockage deeper in the system.
3. Nasty Smells from Drains
Indicates stagnant water, decomposing waste or a dry trap.
4. Toilet Rising High Before Flushing Away
This requires drain blockage diagnosis immediately as it can signal a main line obstruction.
5. Water Backing Up Into Showers or Toilets
One of the most serious residential and commercial drainage issues — usually caused by a main sewer blockage.
6. Standing Water Around External Drains
Often caused by collapsed pipes, silt buildup or structural failure.
7. Damp Patches on Ground or Walls
A hidden leak that requires a CCTV drainage survey.
8. Outdoor Drain Overflowing After Rain
Could be a capacity issue or an underground obstruction.
9. Low Water Levels in Toilets
Usually caused by venting issues, blockages or partial siphonage.
10. Sudden Increase in Rodents or Insects
Often due to broken drains, cracked pipes or improper sewer sealing.
Tex Services specialises in identifying these common drainage problems using CCTV surveys and professional equipment compliant with UK regulations.
