What Are Drain Survey Services and Why Do You Need Them?

Drain survey services are a crucial aspect of building and property management. They are essential for identifying and resolving problems with drainage systems in buildings, including homes, offices, and commercial premises. Drain surveys are designed to help identify blockages, cracks, and other defects in the pipes and sewers, as well as to evaluate the overall condition of the drainage system.

In this article, we’ll take a closer look at drain survey services, the different types of surveys available, and why you might need them.

What are Drain Survey Services?

Drain survey services are a specialized type of inspection that is carried out by professional surveyors and engineers. The purpose of the survey is to assess the condition of the drainage system, identify any problems, and provide recommendations for repair or replacement. Drain surveys can also be used to check the pipes for leaks, blockages, and cracks, as well as to evaluate the overall health of the system.

Types of Drain Surveys

There are two main types of drain survey services: CCTV surveys and physical surveys.

CCTV surveys for drains are the most common type of drain survey, as they are quick, non-invasive, and cost-effective. During a CCTV survey, a camera is attached to a flexible rod and fed into the pipes to inspect the inside. This allows the surveyor to view the condition of the pipes and identify any problems that may need attention.

Physical surveys, on the other hand, involve a more in-depth inspection of the drainage system. This type of survey is often used when there are significant problems with the pipes, such as blockages or structural damage. During a physical survey, the surveyor will physically enter the pipes to inspect them from the inside.

Reasons for Carrying Out a Drain Survey

There are several reasons why you might need to carry out a drain survey, including:

·       To Identify Blockages

One of the main reasons for carrying out a drain survey is to identify blockages in the pipes. Blockages can occur for a variety of reasons, including the build-up of waste materials, tree roots, or foreign objects being flushed down the toilets. Blockages can cause serious problems if left unchecked, including sewage backups, unpleasant odors, and health risks.

·       To Check for Leaks

Another common reason for carrying out a drain survey is to check for leaks in the pipes. Leaks can be caused by cracks, corrosion, or other factors, and can lead to water damage, mold growth, and other problems if left unchecked.

·       To Evaluate the Condition of the Drainage System

A drain survey can also be used to evaluate the overall condition of the drainage system. This is particularly important for older buildings, where the pipes may have suffered from years of wear and tear. A survey can help identify any areas of the system that need to be replaced or repaired, ensuring that the system is working effectively and efficiently.

·       To Meet Health and Safety Requirements

Finally, drain surveys are often required as part of health and safety regulations. For example, if you run a business or commercial property, you may be required to carry out regular drain surveys to ensure that the system is safe and hygienic for employees and customers.
