PTS Flowbench Forum

What is the best way to test your bench for a leak.I heard a pop noise when i was flowing an exhaust port and cannot seems to get the pressure i was getting before.I do not see anything that stands out.
Thanks in advance

put it in exhaust mode with a few inches (10 or so should do) of positive pressure and spray some soapy water on all the seams, seals and fittings. i had some elusive leaks and tried using the velocity probe but the old soapy water trick is what finally did it.

Yup, a bucket full of soap suds, and scoop up big hand fulls of bubbles will locate even a pin hole leak.
