#1--- What??? The hell you can't. You damn sure better if you know something is wrong. If you don't know it's wrong... go back to changing oil til you get the proper education.
#2--- What???? Of course not, if it's cosmetic in nature. Nothing Nolan posted falls under that category though...
#3--- What????? Anyone who does not identify the corrigated pipe used as an improper use of materials shouldn't be inspecting for a living... sheesh!!
#4--- (What the plumbers use) Uniform Plumbing Code section 701.2 states, "Drainage fittings shall be of cast iron, malleable iron, lead, brass, copper, ABS, PVC, vitrified clay, or other approved materials
having a smooth interior waterway of the same diameter as the piping served..."
#5--- See 1, 2, 3, & 4 above.... No need to predict the future. The future is the present.
This is a joke right
