Dr. Z i am a student attending hvac school. i was watching this video and wondering how would u pumpdown your linesets on a new install if you can only use the gauges midseated or cracked off backseated and still be exposed to the unit that comes from factory with refrigerant?

@MrFatback68 You can totally front seat the valve to stop the flow.

Thanks Dr. Z! You should really make a video tutorial series or something like it and sell it. You have a good way of explaining things. This video on king valves is great. You show us the inner workings of the valves not just how to use them.

Thanks again Dr. - gordygordy74, Mindy in Los Angeles :-)

@gordy19741974 Thanks for the compliment.

Hi Dr.Z! I love watching your videos. Have two quick questions. On a regular residential service valve if I have the stem backseated can I safety replace the core on the shrader valve?

And also, is there anyway to check the suction pull of the compressor? Someone told me you could but I don't see how. With the valve frontseated or cracked I can't. And if I frontseated I cut out the compressor side. Keep them good videos coming. :-)

@gordy19741974 I think that it would be easier to use a core replacement tool. You can check both the head pressures and the suction pressures with a set of manifold gauges.

I'll probably get to those sooner or later. Thanks.

Do you think you could do a video about hot gas bypass valves?

Thanks for watching.
