My Badger 5 is leaking from a hole in the housing. Grrr. I have a new Badger 5 in a box, begging to be installed. Only for aesthetics, I would like to change the basket strainer on the sink side and maybe change the strainer on the Badger side, too. My plumbing is pretty old, but working. Based on my pictures, would you guys change everything out to PVC or should I let sleeping dogs lie and JUST change the Badger? I'm also enclosing the picture of the next door condo's kitchen. If you guys suggest I redo everything, is that a good example?
