D2 PIPE SIZING tool will help you ensure your pipework is Building Regulations compliant. Just specify your pipe diameter, pipe run length and number of bends and you’ll know instantly if it falls within regulations.
Alternatively, adjust any of these three attributes until you find the best suited combination for the job.
