🚰 Drainage Pipes

Residential Drainage Pipes

Drainage pipes carry wastewater and stormwater by gravity from fixtures and buildings to sewers or soakaways. Common materials are PVC, UPVC, and HDPE, sized roughly 32-315 mm. Correct fall (slope), venting, and jointing prevent blockages and trap siphonage.

FAQ

What slope should a drainage pipe have?
A common rule of thumb is a fall of about 1-2% (roughly 1:40 to 1:100) for horizontal drains, but confirm against your local plumbing code and pipe size.
Can drainage pipe carry hot water?
Standard PVC/UPVC drainage is rated for intermittent, not continuous, hot discharge; for sustained high temperatures use pipe rated accordingly — confirm against the datasheet.
