Specifications:
The document outlines specifications for PVC-u soil systems, including BS4514 for 82mm systems, EN1329-1 for 110mm and 160mm systems, and BS5627 for pan connectors. These standards ensure compatibility and quality in soil pipe and fitting systems.

Procedures:
The choice of joint system for soil products is based on personal preference. Ring seal systems offer flexibility due to their mechanical nature, while solvent weld systems provide a homogeneous joint, ideal for areas like boxings and ducts.

Colour Availability:
A chart is provided detailing the color availability for different sizes and types of soil systems:

• 82mm Ring Seal Soil (PVCu): Black/Grey
• 110mm Ring Seal Soil (PVCu): Black/Grey/Brown/White
• 160mm Ring Seal Soil (PVCu): Grey
• 82mm Solvent Soil (PVCu): Black/Solvent Grey
• 110mm Solvent Soil (PVCu): Black/Solvent Grey/Brown
• 160mm Solvent Soil (PVCu): Solvent Grey

Note: 'Grey' refers to standard light grey, while 'Solvent Grey' is a darker shade introduced for Solvent Soil and MuPVC Waste Systems only.

Standards:
The document references standards that ensure the quality and compatibility of soil systems, emphasizing the importance of adhering to these standards for effective installation and performance.
