found the problem!

the needle valve and the solenoid were both clogged up, got them all apart now and cleaning them.

If they are plugged up it sounds like they might have had water back up into them. Use should have a check valve between the solenoid and reactor I use two cause I haven't found them to be 100% reliable.

my solenoid and needle valves are toast

Try immersing the needle valve and valve part of the soleniod with a vinegar soln. Whadda you got to lose

we did..it is insanely corroded inside the solenoid. i'm upgrading all new regulator/solenoid etc.
