Un-plasticized poly vinyl chloride and Polypropylene Random Copolymer are the full forms and material used in manufacturing UPVC and PPRC pipes respectively. UPVC is used for conduits of sewerage and electrical whereas PPRC is used for water and gas system.

While purchasing UPVC conduit for sewerage and electric systems, make sure the brand is well known and reputable in the market. Most of the brands manufacture pipes in two qualities namely “Pure”, “Medium” and “Conduit”. Quality that is preferred and should be used during construction of house is “Medium”. Pipes should have good stress and weight bearing capacity. Pipes of smaller diameter such as ¾” or 1” which are mostly used for electric conduit should be easily bendable. PPRC is also manufactured in two gauges specified as “PN20” and “PN16”. PN20 PPRC is used where water is required to be pumped with higher pressures. However PN16 is most commonly used as a standard practice in construction of houses. Some companies manufacture special pipes for gas that are easily available in the market such as shown in the picture below.
