On issue 1: have you checked the pressure gauge is ok? The tech could check with a pressure testing portafilter ( gauge built in).
Also I guess you have monitored the flow from the bypass valve (opv) while brewing with a blind basket? Adjusting the opv is what sets the max brew pressure. On most brewtus with onboard tank the overpressure flow goes back into the tank.

Friends,--I have two separate issues I am hoping this communities help with. I am really trying hard to join the Brewtus community by procuring a used unit, but the two Brewtuses (Brewti?) I have found both have issues that I am hoping to get your help addressing! For ease of reference, labeling as (1) and (2) below.(1) I am talking to a coffee tech who is restoring a Brewtus III that I was hoping to buy - it already had a new vacuum breaker, new control board, rebuilt E61 grouphead installed, but was unable to build up past 8 bars brew pressure. The tech has now replaced the pump and OPV but it still has not solved the problem - the machine does not build pressure past 8 bars. Is there any other thing in the pressure path that could be causing this problem? Could it be the Aerator valve? And if so, how to check, confirm and fix the issue? ANY insights would be VERY welcome. You guys can take solace in the fact that this has a professional coffee tech stumped...I am posting here as a hail mary, as this unit is local to my city.(2) Separately... given the delay with this and uncertainty, I have been talking to another seller about a Brewtus II. this Brewtus is plumbed in at the moment - and the seller does not have the reservoir. I sadly live in a small apartment, where I'd rather not plumb in the machine until I move later in the year, and there is simply no space for a 5 gallon bottle and flojet. A few questions:A) What is the overall process to convert from plumbed in to reservoir? Happy to refer to the attached Brewtus compendium PDF for easy referencingB) What parts are needed and how long/ambitious would this project be for a budding but not experienced DIY guy?C) What type of reservoir could fit and where could I buy it from?D) Bonus: Would this process be reversible? If I move to a larger apartment and if I decide to plumb-in.Even a quick thought on one or both of the issues would be great!
