Project Overview

MR Drains attended a property in Esher, Surrey after the client reported slow drainage and recurring minor blockages. The issue was suspected to be within the internal pipework.

The Problem

The client was experiencing:

  • Slow draining sinks/wastewater
  • Frequent minor blockages
  • Reduced flow efficiency

Upon inspection, the problem was identified as significant scale build-up inside the pipe, restricting the internal diameter and affecting normal flow.

Site Findings

A closer inspection of the pipe revealed:

  • Heavy scale deposits along the pipe walls
  • Grease and waste residue accumulation
  • Noticeable narrowing of the pipe opening

The image clearly shows thick build-up around the inner surface, leaving only a limited space for water to pass through.

Challenges on Site

  • Build-up was hardened and adhered to the pipe walls
  • Risk of damaging the pipe if removed incorrectly
  • Limited access due to internal pipe location

This required a controlled and professional cleaning approach.

Our Approach

1. Internal Inspection

We assessed the extent of the scale build-up and confirmed there was no structural damage to the pipe.

2. Mechanical Descaling / Cleaning

Using specialist equipment, we:

  • Broke down hardened scale deposits
  • Removed grease and residue
  • Restored the internal pipe diameter

3. System Flush

The pipe was thoroughly flushed to:

  • Clear remaining debris
  • Ensure smooth water flow
  • Prevent immediate reoccurrence

Equipment & Techniques Used

  • Mechanical descaling tools
  • High-pressure flushing equipment
  • Drain inspection techniques

Results

  • Significant improvement in water flow
  • Removal of internal build-up
  • Reduced risk of recurring blockages

The pipe was restored to near-original capacity without the need for replacement.

Conclusion

This scale build-up case in Esher, Surrey highlights how gradual internal deposits can severely impact drainage performance if left untreated.

At MR Drains, we provide professional pipe cleaning and descaling services to restore efficiency and extend the lifespan of your drainage system.
