Mark VII setup is crappy


The first picture is a modified version the second picture it the original Mark 7 setup.


I had a problem with one of the bays weep system not working and noticed this solenoid (first picture).  How many solenoids do you need for a weep system?  One per bay?  And why is the pvc labeled “Weep” and the solenoid labeled “Tire Clean Weep Lock” it is connected to the high pressure hose?  It does not make sense.  I guess Greg, the previous owner, changed the weep to one solenoid and cut off the “Tire Clean” solenoids?  I need to rip out half the crap in this Mark 7 setup.  The problem with the weep was that the needle valve was clogged.  Is the needle valve really necessary for a weep setup?
