Whistling Vented Loop

Post by Freedom145 »

After replacing my sanitation hoses this spring an annoying but otherwise benign whistling noise occurs in the discharge vented loop whenever I pump the head. I had cleaned the loop prior to reinstalling and replaced the duckbill valve but to no avail. Any suggestions to purge air from the system.
