Pump Design - Comprehensive Assembly Plan And Visual Guide
A system consisting of a central pump (P1) that feeds water into a piping network. The flow is split (P4) into two branches, which then route upwards and connect to a central distribution manifold (composed of P13, P15, P18 and connecting pipes). This manifold has three outlets, each equipped with a ball valve (P21, P26, P31) and leading to a long vertical pipe (P24, P29, P34). - Pool/Spa Pump and Piping System
