Pump inlet drain position
Thread Content
I would like to ask fellow sailors: should the pump inlet be drained before or after the filter? I have encountered both scenarios; I’m not sure what the advantages and disadvantages of each are, or which scenario is preferable
The standard piping setup includes an inlet valve, filter, drain valve, reducer, pump, outlet reducer, pressure gauge, check valve, drain valve, and outlet valve.

The drain should be at the filter, after all, it’s the lowest point. Additionally, the pump outlet also requires a drain, located after the check valve and before the outlet valve
The standard piping arrangement is inlet valve → filter → drain valve → reducer → pump → outlet reducer → pressure gauge → check valve → drain valve → outlet valve.

I would like to ask, what is the impact of allowing complete drainage before and after the filter?
