What Does a Drain Survey Involve?

A home buyers drain survey is a thorough inspection of a property’s drainage system. It goes beyond what a standard home inspection covers. During a drain survey, a qualified drain engineer will use specialised equipment, including remote CCTV cameras, to examine the condition of the drains and sewers. The process typically includes:

  1. CCTV Inspection. High-resolution, remote-control cameras are inserted into the drains to capture detailed footage of their interior. This allows experts to identify any issues, such as blockages, cracks, or misalignments.
  2. Flow Testing. By conducting flow tests, surveyors can determine whether there are any obstructions in the drainage system that could lead to slow or blocked drainage.
  3. Identification of Drainage Layout. Surveyors create a comprehensive plan of your property’s drainage system, detailing the location of drains, manholes, and inspection chambers.
  4. Assessment of Condition. Any issues found during the survey are documented and assessed for their severity. This includes identifying potential future problems that may require attention.

What Problems Can a Drainage Survey Detect?

A home buyers drain survey can uncover a wide range of issues that might not be immediately visible but could cause significant problems down the line. These problems include:

  1. Blockages. Accumulated debris, grease, or tree roots can lead to blockages that may cause sewage backup or flooding.
  2. Cracks and Damage. Over time, drains can develop cracks, fractures, or structural damage, which can lead to leaks and subsidence.
  3. Misaligned Pipes. Shifted or misaligned pipes can result in slow drainage, gurgling sounds, and even sewage leaks.
  4. Tree Root Ingress. Tree roots are notorious for infiltrating drainage pipes, causing blockages and damage.

Why Is It Important to Have a Plan of Your Drains?

Why Is It Important to Have a Plan of Your Drains?

Having a detailed plan of your property’s drainage system is essential for several reasons. Drains require maintenance in exactly the same way that your roof or guttering does, but because drain are largely invisible, they tend to be forgotten until a major problem occurs. A CCTV drain survey is essential preventative maintenance.

If, in the future, you want to make alterations to your property, having a drainage plan is extremely helpful for architects or builders. It allows them to avoid – where possible – the drainage infrastructure. This expedites the planning and building process for you and saves costs on your renovations budget.

A drain plan allows you to understand your property better. If there are potential issues with your drains, getting repairs done early will be far more cost-effective than suddenly being overwhelmed by an emergency.

Why Do Buyers Need a Drain Survey?

While a standard home survey primarily assesses visible aspects like the property’s structure and basic systems, it often overlooks the critical but concealed infrastructure below ground – the drainage system. This underscores the necessity of a thorough drain survey.

Hidden Issues Uncovered

Drainflow engineers have on numerous occasions detected concealed issues through our CCTV drain surveys, including problems like tree root intrusion and cracked pipes. These issues are of utmost importance and demand immediate attention. Without a drain survey they would continue to deteriorate without your knowledge.

Drain Surveys Give You Negotiating Power

Imagine your home buyer’s drain survey report suggests £2,000 worth of necessary drain repairs. If you identify this issue before finalising the purchase, you have the opportunity to negotiate with the seller and request a reduction in the house’s price to offset these repair costs. Failing to conduct the drain survey could potentially leave you with this expense after you’ve already moved in.

You’re Armed With Knowledge

Knowing the state of your drainage system arms home buyers with the knowledge they need to make an informed decision about whether to proceed with the property purchase or reconsider. It also helps with the cost of home insurance, as insurers often take into account the condition of your drainage system as a key factor in determining coverage and premiums.

How to Arrange a Drain Survey

A home buyers drain survey is normally carried out after the seller has accepted your offer, making it one of the final stages in your house-buying journey, just before the contracts are finalised. This crucial step occurs before you move into the property.

  • Find a Drain Survey Provider. You’ll need the services of a specialist drain surveyor. Once you have booked in the survey, they will do the rest.
  • The Survey is Carried Out. The survey typically takes one or two hours. It may be more depending on the complexity of the property’s drainage system.
  • Detailed Report. At the end of the survey, you can expect to receive 3 valuable components: firstly, a comprehensive ‘health check’ report detailing any issues identified within the drainage system. Secondly, you will receive a drainage map, providing you with precise information regarding the location of your pipes and clarifying which ones fall under your responsibility. Finally, you’ll be given a CCTV recording, which can prove beneficial when dealing with insurers and mortgage lenders who may require evidence of your drain’s condition.
