4" clay to 4" pvc
My question is I have a old house (built in 1927) I have clay piping for my sanitary sewer lines. I have a old out dated half bath in my basement that I wanted to add a shower. I cut up my concrete and pulled out all the old clay with PVC and connected it to the clay with a fernco boot. Is the fernco the best way to make this union between the two. Or is there a better way. Is it safe to b bury the fernco. Any advise would be great thanks

Get rid of all the clay now while the getting is good, all the way to the sewer main or first tank, whichever applies. If you don't have root infestation now, you will the day you screw on the last switch plate, then you will truly kick yourself in the AXE.

It's contrary to the plumbing code.

Almost everywhere and forever (until PVC and ABS)...
below grade in the house has been cast.

I'm in Cleveland Ohio and under my basement slab is 4" clay pipe for my sanitary sewer lines. I'd rip it all out but it would mean having to move my furnace and hot water tank and dig under a load bearing block wall. So if a fernco will last and is a acceptable way to join the two it's gonna have to do. Im a floorlayer so I thought I'd ask someone that actually has worked with and buried a fernco before. Any feedback is greatly appreciated.

Clay is no longer allowed inside the footprint of a building. You have it in a bad spot so it's your choice to live with it. Clay pipe sections are short so there are multiple joints- and the joining method is usually grout which crumbles over time. This means leaks- and leads to roots and pipe failure.
The fernco is the accepted way to join to clay. But again, in my area, they are not allowed inside a house- though I see it done often and effectively.
As for your picture- you should not use tees on their backs- use the code approved method of a wye and 45 (combo) instead.

which code are you under? i see a couple problems with that set up.

jagans 03-03-2013 10:02 AM

Eplumber is correct. you need Y and 1/8th bends at those tie ins. Those Tee's are going to cause clogs. Combo fittings can be used too, but not sanitary Tees.

Thanks for the feedback guys I greatly appreciate it. Ever have floorlaying questions give me a shout. I'm a journeyman install certified floorlayer. I'm also certified in moisture remediation and zero tolerance pours.

what is this ?

Pouring self leveling cement to exactly level. With self leveling cement there are always tolerances like its "level to within a 1/4 inch". Zero tolerance pours half to be exactly level. U really only see it at TV station because the cameras have to be completely level for the news or at hospitals for the MRI and CAT Scan machines.
