How To Details

Criteria 14 – Waste Pipes:  All pipes are brought no higher than 14″ to centre of the pipe from floor  level.


Let’s look at the waste pipe under your sink. It’s normally black plastic and comes through the wall 18 inches above the floor.

By simply bringing it no higher than 14 inches from the floor now, you’ll have the ability to lower the sink and counter in the future without rebuilding the entire plumbing system.

The cost is literally nothing. The potential benefit to someone who needs or wants to sit in front of the bathroom sink is enormous.

Lowering the waste pipe to meet SAFERhome standards.
