You need to vent the air from the high point and drain the water off at the low point. openning the vent while draining.

Dear members;

Is it true that vent and drain are needed at every high and low point of piping if water is used for hydrotest? what if air or steam are used?

Can someone explain the general procure about how to use them in the hydrotest?

I know these question seems too junior but I do have confusion on it. your response is appreciated.

Thanks
Robert Liu
