Quite a rabbit hole I'm down on the revamp of my wash. Now that the chemicals are updated and not the same soap for 3 functions I can see that there are leaks in the walls separating the tanks. Was thinking about flex paste but worried about chemical resistance. Getting it welded is way too big of an endeavor right now. Was thinking a thick plastic rectangular container to drop in would work and last indefinitely but not sure where I'm going to find that.

Leaking hydrominder tanks

I haven't looked at this part closely but the tank just comes off the stand on these coleman racks?

I have successfully used silicone sealer and Flex tape to seal the partition on my D & S SS tanks. It's an inexpensive experiment.

Why go down the rabbit hole further? It's not that expensive to do it right and use SS tanks. KR sells these mix tanks. Although, when I bought these about 10 years ago, they were $70 each!

I'm not positive, but I believe so. They often come with a second set of tanks to the right that you're meant to pour the chemicals into. I'm not positive, but I think it's the same tank without any bulkheads welded in. It just sets into the frame. Those are often sold because people would rather pull out of 5 gallon jugs.

Those are tiny but work okay. It would be nice if they welded in a drain port but they would probably be $50 more.

Yes they are tiny, about a gallon or a little more. I didn't have much room, so they were a perfect fit. I have the hydrominder floats attached with no chain, so they only fill about half way. I've never had an issue running out of chemical on any of the 4 tanks with my 4 bay. Soap and wax flow at 10oz per minute per bay and PS and FB flow at about 20 oz per minute. So between 40 and 80oz per minute....Very doable even if all bays are running the same selection. As for draining, I can't really remember having to drain them! Been installed for about 10 years! The only chemical I seem to have an issue with is the yellow TF in a SS (3) tank system, reason unknown. Red and blue is never a problem. Algea forms in the yellow tank when its really hot outside and in the Er. Those tanks don't have a drain either, so I use a 2-3 gallon oil vacuum pump/tank to pump out the liquid. Works pretty good no more often than I have to do it.

I just bought a hand transfer pump, which is on sale right now. It worked really well. I normally fill a piece of hose with water and siphon, but I think I'll carry this pump with me.

Amazing deals on this Multi-Use Transfer Pump at Harbor Freight. Quality tools & low prices.
I'm going to try flex paste tomorrow. Because the tire cleaner is down I drained that tank and could see the .75" spot at the bottom of the dividing wall where liquid is getting through. I'll probably just do wax/soap right now, put some solution in 5 gallon jugs and let the sealant cure at least 24 hours. If it buys me 6mo-1yr that's fine. Do I have to hang jugs or is the siphon sufficient to leave the jugs on the floor and run hose to solenoids?
No no, 3/4" wide along the seam. I can't see it at all, only the water coming in when I siphoned out the tank.
