Plumbing is one of the most critical aspects of residential construction, especially in Kerala where high rainfall, humidity, and varying water quality directly affect plumbing systems. Proper planning and material selection ensure long-term durability, hygiene, and water efficiency. This guide explains everything you need to know about plumbing for residential buildings in Kerala.

1. Understanding Kerala’s Plumbing Conditions

Before planning plumbing work, consider local factors:

Selecting the right pipe material is crucial:

a. PVC Pipes

• Affordable and corrosion-resistant

b. CPVC Pipes

• Suitable for hot and cold water supply

• Long-lasting and heat-resistant

c. UPVC Pipes

• Used for external water supply and drainage

3. Water Supply System Planning

Efficient water supply is essential for daily use:
