The only reference to pipes found is Tight In Pipe as a pipe reinforcement technique.

Fit a non return valve to the hot supply (nrv) . If the cold supply is direct (it shouldn,t be) fit a double check (double nrv) to the cold also.

NRV is Non Return Valve which is prevents to liquid flood back to the suction line over the impeller or other else.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
Eng means English and if there is engg then it is engineering ! allright na
it means exempli gratia in latin but in english it means for example
Auto recirculation valve is used to ensure a minimum flow is maintained through the pump all the time. Recirculation valves are mostly combined with Non Return Valves in the main flow pipe , when flow is established through the discharge line which means that the NRV is open , recirculation valve is closed through a mechanical linkage between the NRV and recirculation valve . Usually the recirculation valves develops passing through it after a period of time due to wear out in the contact points between the NRV and recirculation linkages.
