Flowjet hoses

[Hamilton's Car & Dog Wash]

Hey guys, I have searched and searched and so far haven't found this in this forum. I'm having issues with my tire soap and presoak manifold feed hoses from the flowjet pumps leaking. The hoses swell a little, get hard within weeks and sometimes even blow off at the manifold hose barb. I'm currently using clear braided 1/2 I'd 200 psi hose. My flojets are set at 50 psi. Double clamps on the hoses at the manifold. They also have backflow valves at the manifold. Am I using the wrong hose? Different problem?

You might have a check valve above one of the booms that's bad or failing and allowing high pressure back into the hoses.

Wow did you build this setup

Absolutely not, have been rebuilding it. I purchased it a couple months ago. Kinda a old picture that I posted above. Im trying to get rid of all of the problems and just making things work better for the customers and less maintenance for myself. Just put all of the foam brush foamers above the bays last week. Got rid of the 1/2 braided hose and ran the 1/4 poly. That worked 1000% better.

You sir was correct. It finally showed up while I was in the ER last week. One bay had a bad check valve. Thanks for the input!

I'm a little surprised that the pump didn't blow apart or get ruined by the back pressure, seen that a few times.

It was blowing water at every single seal in that pump. Pump is still working for now though
