Does anyone ran into an issue for no chemical intake? When we hook up the uptake wand, no Minncare get pulled into the RO. Then we get stuck with one hour rinse.

the chemical intake pump is not working properly, membrane inside the mechanism maybe sticking.
1. try to prime the chemical pump by pushing a r.o. water in the intake side using a syringe (apply a bit of pressure to force the membrane to open) during chemical disinfection then replace the tubing back the port and continue the disinfection using minncare.
2. replace chemical pump.

Does the chemical wand have a O ring on it that may need replaced ?

Yes there should be o-ring otherwise it will not suck the chemical.

I called for the oring and they would not give me the part number for just the oring instead I had to buy the whole wand which is not cheap

just find any o-ring that fits the wand end groove and seals the path.

Like an acid oring, or bicarb oring?

You may need to force chemical into the wand by using a syringe.
