Let me first say that I'm not a tech speak kind of guy so a lot will probably go over my head.
Here is the issue with my three group GB5. When pulling shots out of one group my pressure stays at a consistant 9 bars but if I pull shots from a second group head the pressure drops to 7 before leveling at 7.5 to 8.
Obviously I want consistant shots no matter how many group heads are in use. I've had my RO company out and they have increased flow to the machine and I also had thm put a second holding tank leading into the water pump.
Our shots are tasty and I hate to have anyone get anything other then our best. Any ideas or suggestions would be greatly appreciated.
Cheers
