Closet flange to old cast iron.


So before I glue all these pipes together and lay cement over the top I wanted to run this by you guys. My main question is, am I going to have an issue with clogging.... The whole run is about 3 ft total and runs from the toilet flange attached to a 4-3 90* closet flange (disregard that 6" of 4" pipe that sticks out of it), into a straight pipe that runs about 2.5 ft into 2 45* and into the cast iron where the original toilet used to be. The run has about a 1.5" drop slope from start to finish Your comments are definitely welcome.

I can't really tell, from your pictures -
It looks like you've got a "tight" 90, underneath the toilet.
You might want to go with a "wide" 90 (sweep)
Wait and see who else has comments!

Thanks ya That's what I was thinking but the problem is keeping the slope... I'm fighting the water line which the pipe has to run under.if I run a 4" long sweeping elbow I don't think I will be able to achieve the slope I'm lookin for..... Still open for comments

Hey it looks pretty good to me. I wouldn't worry to much about the tight 90. I had to replace my plumbing on the upper story of my house which only has 2x6 joists so I didn't have alot of room to work with. What I had to do was use a street 90 and then a flange that fit over the street side of the 90. Works like a charm.

You need a 1/4" per foot slope...no more. Too much slope can actually be a bad thing, allowing water to move PAST the waste rather than moving it along the pipe.

Not sure why you used a 4x3 90 instead of a 3" 90, but each to his own.
Medium sweep 90 will work just fine. Its done all the time.
As mentioned- 1/4" per ft is optimum. More and your solids can be left behind.

1/4 per a inch slope so in 3 feet should have 3/4 inch full run, to much slope and water runs faster than solids then can cause clogging
also if those are copper water lines protect them from being in contact with concrete due to long term exposure will cause corrosion and leaks then you will be cutting concrete again.
also pin new concrete to old by drilling holes at least 2 inches deep into side of old concrete and putting in rebar in holes that way it locks old to new
