Help Changing Dual Diaphragm Flojet Pump

Hi everyone,
I need your help. My foam brush Flojet has a small crack as of this morning. Need to change it, but would like to know if there's a way to shut off the foam brush soap coming in. I can't seem to find a shut off valve? For those of you familiar with this system could you tell me if there is? And if there's not what would be best way not to waste so much soap while trying to change it out. It's my first time doing this. Pictures and small video are attached.

Thanks!

Should be one at the tank outlet. If not just put a pair of vice grips on the hose or turn off water to the hydrominder.

That's aftermarket. Jim Colman pump stands have electric motors with pro con pumps. As your flojets go bad I would replace with the original set up. A lot more reliable.

1. Turn off air at nearest shutoff. Might have to turn off directly at compressor outlet. It looks like 3/8" air line feeding that pump. Go to Home Depot and get a 3/8" push connect ball valve. Once you turn off the air install the ball valve right before the pump then close it. You can turn the air back on now for all your other equipment leaving it only shut off for the pump your working on.

2. Turn off hydrominder ball valve in foam brush tank.

3. Unhook product supply line from tank to your Flo jet and fold it in half then zip tie it.

4. Do the same with your outgoing product line so you dont make a mess as those solenoid blocks will still let chemical flow backwards. Fold line in half and zip tie it.

Now your ready to change the pump.

I like JC systems a lot but im convinced the original engineer had a fear of ball valves resulting in making a lot of repairs more complicated/messy then they need to be. When I rebuild their pump stands I leave everything the same because its a great set up but I add about 20 ball valves to it where they should've had some in the first place.

Those double flojets are way overkill for a 4 bay setup system. A single flojet will more than handle that. No need to spend the money on the doubles. With the price of flojets nowadays, procons are seeming better over the long term, both in cost and longevity
 
Your actual flojets may still be good, just saw your video, just the manifold connecting the 2 has a leak.

Also, air line is probably 1/4, that's what it is on our double setup we have remaining

1/4" is what is on outgoing solenoid supply air and product lines. From the picture air line going into the pump is bigger. Most likely 3/8".
