pvc to cast iron hub using fernco-can't get it!

What have I done · 08-20-2009, 09:31 PM

Ok I thought the hard part was going to be getting the cast iron seperated. I drilled the lead and got the cast iron seperated at the Bell, I got a Fernco that goes inside the cast iron Bell and the pvc goes inside the fernco.

I can Not get it to go in, I tried putting the fernco in 1st then the pvc. this just pushed the fernco in further.

put fernco around the pvc and tried "tapping" it into the cast iron. Couldnt get it in past the 1st ridge of the fernco. Still had at least and inch to go.

Tried lubing everything up with dish soap. No better.

What am I doing wrong or better yet HOW CAN I make this connection from Cast iron to PVC.

thanks

What I do is take a short piece of pipe say 12" and taper the end. Lube the dough-nut (fernco) inside and the pipe outside. Insert the pipe into the dough nut and place a short piece of 2x4 over then end of the pipe. Then use a hammer and strike the board to drive the pipe in. Use a PVC coupling to reconnect the pipe end

Yes thats how I was doing it. I had a 5" piece of 4" PVC figured I could get that locked in place with the fernco then go to town on PVC connections. It just wont go. The donut I got is a ferncop44u-405 "for sewer and drain use only". I was using dish soap as a lube is there something better?

Thanks for the quick reply also

I use faucet grease.

Sometimes one or two hits and slips right in other times I really have to pound to get it to go in. (That just sounds so wrong)

I had on one time where I had to hold the 2x4 and have my helper swing the hammer.

If you make a 30 to 45 deg tapper on the end of the pipe it really helps. Also 5" isn't long enough. Use at least 8-9"

not sure what the last message was about??? Sultini?

Anyway the fernco I was using came from A box store. It was fernoc brand but I could not get it to accept the PVC

I went to a plumber and the donuts he had were beefier and he said to do exactly what I had been trying

The donut was $20 as compared to the box store's $9.. BUT IT WORKED

had to wack the PVC good with a BFH but it went in...on to the next project!

thanks for your HELP
