and where or what this device is and if it is possible to service or replace.
I have just renewed the EPDW's and vac hoses but do not think this bypass channel is opening correctly. Slight turbine chatter on lift off especially when cold and a "CHAIO" sound , also spooling up doesn't quite sound right ( no nice smooth sounding hiss increasing in pitch ) sounds more hollow is that's a good word to describe. BTW this isn't pedal to the metal stuff , but very low revs and slow speeds.
