A 4-inch flange should work just fine.
Seems to be an odd size- can you upload a picture? What is the pipe made of-plastic, cast iron, lead, copper?hello, i am installing my toilet and the ground pipe is 3 7/8 inch and all i can find is 3 or 4 inch flange's. from what i hear the flange is suppose to go inside the pipe so the 4 inch is too big and the 3 is too small. anybody come across this before?

but how do i get a 4inch flange into the 3 7/8 inch pipe? i also thought maybe putting the flange on the outside of the pipe but wont it leak?A 4-inch flange should work just fine.
it really should not matter if it plastic and measured 3 7/8 id a 3"hub flange measures 3 7/8 od....good point though...ben srMaybe the pipe is not DWV?
I thought you guys were nuts - I could have sworn I read 3 7/8 O.D. somewhereit really should not matter if it plastic and measured 3 7/8 id a 3"hub flange measures 3 7/8 od....good point though...ben sr
no your not nuts ..well i really can't say for sure don't know you that well:laughing::laughing::laughing:...but 4"plastic abs measures 3 7/8 id and a 3"hub closet flange will glue right into it..we do it all the time... of course this is pvc sameI thought you guys were nuts - I could have sworn I read 3 7/8 O.D. somewhere![]()
I didn't say I was nuts- I was questioning you're sanity because I read too much into the thread :laughing::wink:no your not nuts ..well i really can't say for sure don't know you that well:laughing::laughing::laughing:...but 4"plastic abs measures 3 7/8 id and a 3"hub closet flange will glue right into it..we do it all the time... of course this is pvc same
4" whole line because after tile we cut off 4" flush to tile glue and hammer drill 3"hub flange into 4"I didn't say I was nuts- I was questioning you're sanity because I read too much into the thread :laughing::wink:
Do you use 4x3 90's or pipe the whole line in 4"
Your answer has been posted already- please rereadIt is a 4" abs riser in concrete. Is there a flange gasket that goes inside or do I have to bust concrete to get on outside gasket?
