Hi,

Bought a house 3 months ago with some DIY remodeling. Home Inspector found problems with venting in Master Bath. Several fixtures tied together improperly, drains and vents, but no problems were showing. On recommendation, we installed a studer valve.

Never had any problems until this weekend, when Jacuzzi (with studer) started gurgling when running the shower. OK, it could be bubbling, hard to hear when you are in the shower. Also, after hearing the gurgling, the toilet would not flush completely, until waiting a few hours.

After reading this post (https://www.askmehelpdesk.com/plumbing/tub-gurgles-when-flushing-toilet-14625.html), I was convinced I had a blocked vent / venting issue.

However, this morning the Master toilet started leaking under between the floor and the seal! Also the Hall bath toilet will not flush completely either. Starting to think this could be a clogged main line. Any thoughts on how to check this?

Thanks in advance,

-Steven
