Help with foam brush

[Noob]

My foam brush looks like garbage all of a sudden. I’ve tested my water. It’s at 0 hardness. I normally have a smooth foam. I haven’t adjusted any setting on air or product. It’s like this in all bays. What’s even stranger is the fact that it’s sporadic. Its be foamy then not foamy then foamy. Does anyone have any ideas?
My tire cleaner is super foamy which makes me believe it’s not a water problem.

It looks pretty weak coming out of your foam brush out in the bay. Have you changed soap lately? I'd probably go up one tip size on the Hydrominder and see if that doesn't fix your problem. Is there a notch or a hole in the tube coming out of the Hydrominder to prevent siphoning from the mix tank back to the chemical container.

Maybe a hydrominder letting water slowly leak through, watering down the mixture in the tank. It would have less effect on busier days, which could explain why it's sporadic.

My hydrominders are suppose to have the built in siphon break on them. I also drilled holes in the delivery tubes going down into the tanks. I’ll hook up a fresh pale of soap and see if it makes a difference.

I'm not talking about siphoning. I'm speculating that it could be letting city water trickle through. With a trickle, it won't bring any chemical with it, which would water down the tank.

I’m with you now. My apologies. I will check that also.

Try replacing the foot valve on the pick up tubing going into the bucket.

Replace foot valve, change diaphragm, and check/clean hydrominder inlet screen.

What kind of soap are you using?
