Is there a way to add a rodding point to an existing soil pipe elbow? Eg drill a 40mm hole in the corner and put some sort of cap in the hole. The existing rodding point is on a stright section so close to the ground that I can't get a rodding rod upwards from it.
The alternative is trying to break up a lot of very tight pipework in order to replace the elbow with a rodding elbow.
