Malfunctioning back flow preventer

Hi all - new to posting on the forums...

After a flood in 2010 that caused sewage to back up into our basement via the toilet and shower, we installed a back flow preventer on the main. It's been fine until now.

Recently we've been having tons of issues with the toilet and shower: slow drainage, bubbling and "stuff" coming up. I had the mains cleaned last week but it hasn't helped. We were told to run high capacity water: showers dishwashers, laundry until it cleared itself out, but the problems have all started again, bubbling, slow drainage, and the stuff.... now I am afraid to shower or use any water, really, upstairs for fear of what might be in my basement.

Thoughts??

I have called a plumber (again) but would love to have a long term solution. Cleaning doesn't seem sufficient.
