This flexi waste connector from McAlpine gives you a pipe with complete flexibility. It's ideal for tight, awkward spaces with any angle or offset. You can adjust the length from 165 mm to 250 mm so you can fit this item in a range of spaces.
This pipe allowed me to repair a broken old imperial waste by solvent welding into a damaged elbow. The flexible pipe relieved any strain on the repaired joint when connecting to a metric pipe and into a wash basin. The whole arrangement fitted well with no leaks.
