The high pressure gun trigger turned up broken today, which it the first time for me. I was thinking that I could take it apart and just replace the trigger. Looks like you can not replace it.
I then decided to try and fix an old broken gun. I used my easy out and it was not very easy getting it out. In fact the easy out broke, which is another first.
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.
One of my flojet pumps was trying to prime by running non stop. The problem was that my hydrominder stuck, which did not fill the tank, so the flojet was not getting any chemical.
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?
One of my Coleman Fragrance vacuums was having some problem spraying and also one scent did not work. I used some glass cleaner to clean out one on the scents to make in work perfectly. Next, let the fun begin.
I planned to check the solenoid first. It had gluey crap all over it. I cleaned it off and still had a problem.
Next I removed the barb on the solenoid bank. This was clogged so I cleaned it out. I still had a problem.
So I decided to remove the elbow piece and see if it was clogged. When removing the elbow I broke off another barb. Now, where can I find a 1/8″ mip to 1/8″ barb? Now 2 scents do not work.
I leaky high pressure hose and a coin acceptor that works about 90% of the time. The coin acceptor will accept everything then one day will just quit working.
I am having a check valve problem so I replaced it today. I took the check valve apart to see if I could figure out what was wrong. The valve was on tire cleaner and there was no crap stuck in it. Maybe the spring in messed up? Or probably a check valve is stuck in a bay but I can not figure it out yet.
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.
I cross threaded my elbow pvc piece today, then I had to go to Home Depot again to purchase a metal elbow. I needed to add an elbow to allow the weep solenoid to stop all the water.
I can not figure out why this solenoid does not work. It looks like the spring is messed up. But why is there another spring in the solenoid base (last picture). I just replaced the solenoid with a new spare one.
Also when I was trying to repair the weep solenoid I messed up these crappy brass fittings. I love when fixing one problem causes other problems.
