PIPE manufacturers have called for acoustic regulations to cover plumbing and drainage systems.
Producer Durapipe claims noise generated from pipework in new buildings will become increasingly noticeable as regulations on other parts of the property are tightened.
It has called on clients and designers to insist on a maximum sound level for pipe systems.
Building Regulations Part E: Resistance to the Passage of Sound, sets out limits on noise levels but does not include plumbing and drainage systems.
The new building regulations clamp down on excessive sound travelling between adjacent properties, known as flanking sound. Durapipe wants rattling pipework to be included in a bid to stave off contract disputes.
Head of marketing Martyn Rowlands said: 'Acoustics is already high on the public's agenda and we have seen a significant rise in interest for quieter drainage systems as contractors look to meet increasing requirements.'
