Not getting chemical draw on Maxx

[alazo1]

I've tried the following to no avail.

Disasembled the chem pump. Seals, flapper and check valves are ok
Today on Hydramasters advice changed the brass check valve on the hi psi manifold.

It seems to prime once in a while. The priming tube starts pulsing but when it goes to on the needle stays on the bottom (no sucky sucky).

Any ideas?. I put a dema valve at the exit and works ok for now but I'm sure it will be jacked up with the heat soon.

air leaks ? check all hose connections

I would think the 3 way valve is bad (at least that was the problem when I had a MAXX) that is the little knob that has the prime, feed and off positions

I'll look into both those suggestions, thanks.

Thats was my thought, Does your valve leak when you prime?

Check for leaks and change the diaphram in the last step chemical injection.

WHEN IS THE LAST TIME YOU CHARGED THE (PULSE DAMPENER) OR (ACCUMULATER)

Had the same problem with my Prochem......did everything you have & finally changed
the accumulator....Now chemical draw is better than ever....Hope this HELPS...

ps I had no bouncing of the solution hose....just sucking enough air to cause the chemical
pump to lose its prime.

Finally got around to checking the few suggestions out this Sunday. Hoses do not leak and 3 way valve appears to be working.

Here's the thing though, it primes ok. When you bring it back to the on position the little metal piece inside the chemical thing drops even after keying the way, but it is actually drawing now. I did about 1 1/2 hours on it today and the 5 gallon tank was at about 1/2 mark.

Any ideas as to why the metal piece is not adjusting?
