is the chemical jug suction hose pumping out water instead of drawing it up? The chemical injection hoses are pulsating.
why?

What is the brand/model machine you're using?
It sounds like you need a new diaphragm.
But what do I know?

Hole in diaphragm or bad check valves

I'll check if The flow meter isn't the issue.
The water pump has 3300 hrs and I've only done oil changes. maybe a rebuild is in order?

I don't run chems through my chem meter/machine. So I would think the diaphragm would last longer.

The opposite:
The diaphragm is getting hit with pressure from the water pump to move the chemical through. When the other side is "dry", it is forced to flex further and is more rapidly damaged. Prime in straight water to put water onto the opposite side of the diaphragm, but keep the meter off.
Or remove the entire chemical pump and you won't have to deal with the issue at all.
You probably also have a bad chemical check valve, which would be why your having water come out the hose.

The new one should be smooth.
The impressions are damage from the pulsations against the air in the “dry” side of your diaphragm.
Is there a deep impression around the edge of your diaphragm?
Post a pic, or send it to me by DM if you don’t like being roundly criticized by the insensitive and gleefully critical crowd here

I think you'll find the problem to be solved...though you still might have a stuck check valve as well.

Thanks for your help. problem solved.
I still need to figure why my transfer pump keeps Crapping out. It offers a higher flow than the previous one. maybe it's too strong?

Happy to help....it is what I do at my store nearly every day.
What are the specs on your pump. Do you have an expansion tank with your pump?

I did have an expansion tank but disconnected it when I thought it might be causing the problem. I posted a photo in another post. The tank is installed above the pump instead of on the floor and horizontally.-- does its orientation matter?
One of the few states I've never been to.
I have fond memories of Montana and Colorado. Mikey has even made Nevada look desirable.
However, I can get the same feeling of red (purple) states in California.
