Thanks Vaughn,

No tap plastics around. I have a few more places to check, but will probably order online eventually.

As for the co2, it's just easier to leave it on. My life is pretty hectic; I've actually left for work still half wearing my night clothes, or whearing my ratty old tennis shoes instead of nice work shoes. There would be many days I would forget to turn on the co2. I guess I could start my photo period after I get home from work. I may get a solenoid, I just need to budget for it. I also want to split my co2 delivery for a second tank.
