💧 DRAINAGE PIPE SLOPE — WHY DOES IT MATTER?

Drainage pipes are installed with a designed gradient to help wastewater flow toward its intended destination.

An unsuitable gradient can contribute to poor drainage performance.

🔹 Why Is Correct Slope Important?

✅ Supports the intended flow of wastewater.

✅ Helps reduce the risk of sediment accumulation.

✅ Supports reliable operation of the drainage system.

✅ Helps avoid drainage problems caused by unsuitable installation.

🔹 What Should Be Checked on Site?

📐 Pipe gradient and alignment.

📏 Pipe diameter.

🔗 Joint connections.

🧱 Pipe bedding and support.

💧 Testing and inspection requirements.

📋 Compliance with approved plumbing drawings.

⚠️ Too little or too much slope can be unsuitable depending on the pipe size, system, and design. Do not assume that a steeper pipe is always better.
