Getting Rid of Open Hopper - Bathroom and Sink Waste

by **bouba** » Tue Oct 14, 2014 1:17 pm

I have a cast iron SVP. I am trying to buy a closed cistern toilet and get rid of the open hopper.

1. Can i cut a section of cast iron and slip some kind of coupling and connect a plastic pipe for a CC toilet. I have seen the project on diydoctor.

2. How toget rid of the open hopper and join it in SVP.

Do i have to change whole stack to plastic or can a connection be made to cast iron.

Thanks.

Hi bouba

Yes, you could get rid of the hopper and convert single stack. buit to be quite honest, in that situation I would be thinking of changing the lot to PVC. That would give a much better chance of connecting a modern P trap toilet, it looks a bit impossible as it is.

Thank you. Is there a list of parts you can tell me if I was buying the lot with a same setup.

1 WC upstairs and 1 each for shower and sink. No bathtub there.

I have clay underground pipe.
