uPVC Pipe Identification & CP Series Pumps – Sump & Groundwater Solutions
Ensure the correct specification for your installation with this guide to uPVC pipe identification and the high-performance CP Series submersible pumps. Designed for reliability and efficiency, these systems are essential for basement waterproofing, sump pump setups, and groundwater control.

uPVC Pipe & Fittings Identification
uPVC pipe and fittings are available in the following sizes:
-
50mm, 63mm, 75mm, 90mm (metric)
-
2” and 3” (imperial)
Understanding the difference is key for correct ordering and installation:
-
Metric pipe: Measured by outer diameter (OD)
-
Imperial pipe: Measured by inner diameter (ID)
This ensures compatibility across pipework, fittings, and pump systems.
