My patio has one Glazed earthenware gully, this is presently used to remove rainwater from the garage roof and also has two waste pipe that take away sink waste water and washing machine waste water. The gully was built over when an extension was built I would estimate from records about 30 years ago. I have just removed the concrete on the patio and I am going to replace it with block paving or slabs. Looking at it the pipe from the kitchen sink is unsightly and runs from the front of kitchen around the wall along the side into the gully. I thought I could install a new plastic gully and then run the underground pipework to the existing gully. I dug down around the old gully and could see that the collar was situated right inside the foundation of the kitchen extension. Not so easy I thought. How would I go about adding a new gully to the old system.I thought that if the underground pipework had run straight I could have used a rubber collar but now seeing the run I am dubious.
I would be grateful of any suggestions.
