Rainfall & ground movement
Norwich gets a fair amount of rain — around 600mm a year on average. That level of precipitation can push groundwater levels up, and that's when you start seeing knock-on effects with plumbing systems. In our experience, it's exactly the sort of condition that makes hidden leaks and water pressure problems worse. Our plumbers carry out thorough diagnostic assessments, camera inspections included, to catch these issues before they turn into something more serious.
Building Regulations & compliance
In Norwich, plumbing work is governed by the Building Regulations, with local council building control overseeing compliance. Notifiable work needs a registered competent person to confirm it meets the required standards. That includes things like backflow prevention testing, which must be certified annually. Tavora makes sure all our repairs meet these regulations, and we'll provide you with compliance certificates for complete peace of mind.
Pipe & material suitability
The plumbing infrastructure in Norwich predominantly features lead and galvanised steel water supply pipes, which are prone to corrosion over time. Given the age of the housing stock, with many homes built around 1890, it's worth thinking carefully about suitable replacement materials. Tavora recommends using PEX or copper, both of which comply with BS EN 806 standards, so you'll know you're getting a safe and reliable water supply.
Local housing stock
Norwich's housing stock includes a fair number of flats and maisonettes — around 35% of dwellings, which is something you notice pretty quickly when you're working in the area. Shared infrastructure can make plumbing access trickier, especially in older properties built before 1919. Tree root intrusion is another one to watch for, as roots from local species can work their way into sewer lines over time. Our plumbers at Tavora tackle both issues with careful planning and root barriers to keep your plumbing systems protected.
