PPR vs PVC vs HDPE Pipes in Kenya: Which to Use Where (with Prices)

Choosing between PPR, PVC and HDPE pipes is the first plumbing decision on any building project in Kenya. Each material suits a different job: hot water inside the house, drainage, or buried supply lines. This guide explains the differences and lists pipes, fittings and tools you can order on Buy More Mall.

PPR vs PVC vs HDPE at a Glance

PPR Pipes: Hot and Cold Water Inside the House

PPR (polypropylene random copolymer) handles hot water from showers, instant heaters and solar systems. Joints are made by heat fusion: a welding machine melts the pipe and fitting together into one piece, so there are no leaking threads. PPR is sold by size in millimetres: 20 mm (1/2"), 25 mm (3/4"), 32 mm (1") and larger sizes for main lines.

Biglit also stocks the full PPR fittings range (elbows, tees, sockets, unions, adapters and plugs) from a few shillings each. Browse Plumbing.

Tools for PPR

PVC Pipes: Drainage and Waste

PVC is rigid and low-cost, and it is the standard for waste, soil and rainwater lines. Do not use it for hot water.

HDPE: Buried Supply Lines and Farms

HDPE is flexible and tough, so it handles ground movement and is common for connections from the water main, farm supply lines and irrigation. It is a cold-water material. Biglit stocks HDPE couplings, elbows, tees and end plugs from 1/2" to 1 1/2":

Quick Buying Tips

• Use PPR for all hot-water runs, and match fittings to the pipe size exactly.
• Buy or hire a fusion welding machine sized for your pipes: 20 to 32 mm for most houses, and up to 63 mm or 75 to 110 mm for main lines.
• Use PVC for drainage, and HDPE for buried or outdoor supply lines.
• Fit gate or ball valves so you can isolate each section for repairs.
