DRAIN SURGEON

Drain surgeon added trap for smell from washing machine and CUT out existing piping, added incorrect pipe instead of an upright pipe. As pipe added was incorrect, caused piping from dishwasher to be unstable and leak. Now the cut pipe for the washing machine is leaking! Kindly stick to drains please! It has cost me time and R1900 for nothing. Perhaps going to get spares was too much trouble?
