Unloader hose problem

I had an unloader hose problem today.  It was the high pressure non-working swivels (which work until the fitting is tight).  After the fitting exchange everything was “WORKIN” just like the license plate says (last picture).

Professional Flojet install

I am replacing my Sandpiper pumps with Flojet pumps.  The last picture shows the setup and this is the reason I could not setup the Flojet correctly.  I guess when the equipment was installed originally the stainless tank was dropped in after this fitting was installed.  I will need to crack off this fitting to replace it.  I want to install a push lock fitting just when it is not very busy.

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?

Bad signs

The pressure gradually dropping and a constant stream of chemical coming out of the foam brush is always a bad sign.

While trying to get the solenoid valve off a leak occurred in the valve.
