Rainfall & ground movement
Devon gets a fair amount of rain — the Met Office puts average annual precipitation at around 1,000 mm. That level of rainfall can saturate the ground pretty quickly, which raises the risk of backflow issues in plumbing systems. That's why proper backflow prevention testing matters here — it's not just good practice, it's needed to stay compliant with local regulations. Tavora carries out thorough annual inspections and provides compliance certification that meets the Building Regulations, keeping your plumbing system protected against contamination from sewage or stormwater.
Building Regulations & compliance
In Devon, any notifiable plumbing work has to comply with the Building Regulations. That means it needs signing off by the local authority's building control department, or by a registered competent person under a self-certification scheme. Tavora makes sure all plumbing installations and repairs are fully compliant, and we'll provide the necessary documentation to meet these standards — protecting your property and keeping everything above board.
Pipe & material suitability
The plumbing infrastructure in Devon predominantly consists of lead and galvanised steel water supply pipes, along with cast iron and pitch fibre sewer pipes. These materials can be susceptible to corrosion and degradation over time, especially in loam soil, which contains about 20% clay. Tavora recommends using modern alternatives like PEX or copper, which comply with BS EN 806 standards, to enhance the longevity and reliability of your plumbing system. We assess your current materials and provide tailored recommendations for replacements or upgrades.

Devon's plumbing infrastructure is predominantly lead and galvanised steel water supply pipes, along with cast iron and pitch fibre sewer pipes. These materials are susceptible to corrosion and degradation over time — particularly in loam soil, which contains about 20% clay. Tavora recommends modern alternatives like PEX or copper, both of which comply with BS EN 806 standards, to improve the longevity and reliability of your plumbing system. Our plumbers'll assess your existing materials and give you straightforward recommendations on what's worth replacing or upgrading.
Local housing stock
Devon's housing stock, with a median year built of 1958, often includes flats and maisonettes that can face some tricky plumbing challenges. Tree root intrusion is a common problem, particularly with species that'll penetrate older sewer lines. Once roots get in, you're looking at blockages and pipe damage that can turn into costly repairs if left unchecked. Tavora's plumbers use advanced diagnostic techniques to identify root intrusion and recommend the right root barriers to protect your plumbing system effectively.
