SVP Survey Services

Soil Vent Pipes (SVPs) are a crucial part of any drainage system. They regulate air pressure, allow gases to escape safely, and ensure wastewater flows efficiently through the pipework. When SVPs develop faults or are incorrectly installed, the consequences can include poor drainage, foul odours, gurgling sounds, and even health and safety risks.

At First Choice Drainage Solutions, we provide specialist SVP survey services designed to give you a clear, accurate picture of your soil vent systems. Whether you’re planning a new build, managing an existing property, or diagnosing a suspected vent issue, our surveys provide the insight you need to keep your systems safe, compliant, and fully operational.

Why SVP Surveys Matter

A faulty or poorly maintained SVP can cause a range of problems, including:

• Foul odours escaping into properties.

• Drainage slowdowns due to lack of air balance.

• Gurgling and bubbling noises in sinks, toilets, and baths.

• Leaks or cracks in exposed or concealed pipework.

• Compliance issues on new builds or redevelopment projects.

By commissioning a professional SVP survey, you eliminate guesswork and gain reliable information on the condition, functionality, and compliance of your system.

Our SVP Survey Solutions

We use advanced inspection equipment and experienced surveyors to deliver fast, non-invasive assessments. Our services include:

• Visual Inspections – assessing exposed pipework for cracks, leaks, and poor connections.

• CCTV Surveys – using specialist cameras to check internal pipe condition.

• Air Flow & Ventilation Tests – ensuring the system balances pressure effectively.

• Compliance Checks – confirming installations meet current building regulations.

• Survey Reports – providing clear results with photographic or video evidence.

This comprehensive approach allows us to diagnose both obvious and hidden issues, while also offering guidance on preventative maintenance and system upgrades.

When to Book an SVP Survey

You may need an SVP survey if you are:

• Planning a new build – ensuring your designs meet drainage regulations.

• Buying or selling property – verifying that systems are safe and functional.

• Experiencing foul odours or poor drainage – ruling out vent issues as the cause.

• Managing high-rise or multi-occupancy blocks – maintaining compliance and tenant safety.

• Undertaking refurbishment or extension works – confirming SVPs are adequate for increased demand.

An SVP survey provides assurance that your system is fit for purpose — or highlights exactly what needs attention.
