Big tree limb came down in garden and smashed through a 100mm sewer pipe. I need to buy a length of pipe and a couple of sleeves to repair the smashed length. On the Bunnings site, I can find a 50mm straight sleeve for $2.50, but the only 100mm sleeves are 'DWV PVC Coupling Slip' for $14. Are they the same thing...is this what I want? And if so, why the price disparity? Will the blue cement work with 30yr old pipes?
