Well I made a dry run today to see if my 5.5HP Shop-Vac had what it takes to blow out my floor drains (2 drains 1 line) but it didn't do the job. I'm assuming I gave it enough time, I ran it for 5 minutes and not a single bubble came out of the drains. Can someone suggest a different brand, model that has worked for them? I really don’t want to spend $300.00 on vacuum/blower if I can help it.
Thanks for your help.
