Got a fixer upper off e-bay a couple of weeks ago and have started the restore process and dropped most of the copper into some citric acid to give them a good clean up.

I bought new cold water 2 way solenoid valves and three way group head valves, however I dont know which way the water flow is. Which way the solenoid valve needs to go in. I think that the arrow needs to face towards the front of the machine.

I also installed new group head solenoid valves and I'm not sure if i installed them the right way, cause once the machine heated up I tried to get water out the group heads and nothing happened.

Any tips or tricks to check? This is my first machine that I'm reconditioning.
