harbor freight air compressor 4 hp 10 gal 90234 leaking air
When I plug in my harbor freight air compressor which is a harbor freight air compressor 4 hp 10 gal model number 90234 it is leaking a huge amount of air from the tank drain valve and I am unable to close it off. Do I need to replace the part?
Elizabeth, sometimes the tank drains turn opposite to what would normally be the direction to close them.
If you try to turn the drain in both directions, and you are unable to close the drain, then yes, I would surmise it's time for a new one.
