Having a heck of a time trying to figure out how to adjust the pressure when the tank is off the system.I have tried to use a bicyccle pump as the manual states but find it impossible to get pressure to 40 psi air just comes out the tank fitting that connects to the cold water line . Do i cap it first somehow then attach? What should pressure be on a 5lb tank when it is hooked up and working right? thz so much pat
