Help identifying hose

[jlouis23603]

Hey all

So I’ve managed to figure out most of my Carwash and what stuff does. But for the life of me I can’t figure out what the blue line is for that I circled in the picture.

each pump has it. The hose comes from a manifold that comes off the main water line. Turning the valve on each hose doesn’t seem to do anything

thanks guys

Could be a poor mans weep system. Where does the yellow hose come from? Do you have a picture of the whole pump set up? Do I see galvanized steel pipe fittings in that picture? Galvanized steel pipe fittings, nipples etc. are a huge no no.

that’s what I was thinking but wasn’t sure.

I’ve been changing stuff to brass cause I’ve seen what can happen to galvanized plumbing. I had a badly corroded nipple on a manifold that i used every curse word known to man removing it.

here’s a better picture. The yellow hose goes to the pressure regulator

Saw a weep setup like that years ago. It was fed from an RO reject tank in an attic. Guy used a weepmizer. It appeared to be working well.
