Hello Tariq. Very nice to hear from you. Thank you for visiting my site, and for writing in.

When you plumb two compressors to one tank, you need to make sure that the air from one compressor does not flow back into the tank or out through the unloader valve of the second compressor, and vice versa.

You will plumb the discharge from the two compressors through a tee into one line, and that one line will then feed the tank.

In the line from both compressors, and before the tee, install a non-return (check valve). Then, when either of the two compressors kicks on, the air from that one has to flow to the reservoir, and not back into the other compressor.

Cheers,

Bill
