Never had any issues with mine whilst mounted on a CT22.
Then again, the vac is rarely if ever running @ flat maggot these days either. Most of my sawing, sanding & routing duties are usually run @ 25-75% throttle since I ditched the Kapex.
Are you absolutely sure that your wee blue tap on the low pressure line is completely turned all the way on? As with most ball valves, the valve lever should be "in line" with the vac line, not perpendicular, when fully opened. Given its relatively small & restrictive ID, perhaps shortening the low pressure line (as much as practical) could help transfer greater negative pressure.
