Sanitary tie-in

[FJD3]

Basement bathroom shower/toilet/vanity (DIY). I was having problems with occasional sewer back-ups. I installed AAV's for the toilet and shower, and a separate AAV for the vanity. I also replaced the previously installed FERNCO tie in to the 3" sewer main with a 3" sweeping 90. I realize this is probably not up to code, but is it acceptable?

Welcome to the Forum FJD3,

I understand these types of repairs, up to code no! , but yes will get you by until a later date. I see the repair is below concrete. Not knowing how you are going to fill the void? If it were me, I would seal it up with a water resistant spray foam VS concrete. So much easier for the next person to dig it up and change it. Best of luck

The 3" Fernco Sanitary tee on its side was WAY wrong. The 3" PVC combo fitting is correct. However, the Fernco couplings need to be the shielded ones for underground installations.

Great advice. Thank you!

Ok. I never considered the shielded couplings. Good to know. Thanks!
