DeWalt DW 55151 air compressor

This is a DW 55151, type 3, I have replaced the check valve, but when you turn it on, air comes out of the cold start valve on the end of the check valve, I traced air comming out of the bottom of the switch ( Brass elbow ), Any suggestions ?

Dump any air from the tank with the air compressor turned off.

Remove, test and clean or replace the tank check valve to see if it's working.

Did this help? Post your answer here if it did or did not, if you would.
