That's true, he he
Did a kitchen sink recently where the home owner had new countertops put in. Was a single basin sink, garb, dishwasher and hook up of new tap and trap arm. "SOOOO Simple he said".
Took his word but also warned him of surprises. Go on a Friday after work and sure enough his connections for the faucet hang 10 inches above the supply shutoffs (that are 3 inches above the bottom shelf of the cabinets; the connection for the garb has gone missing; and it's too late to hit up a store for parts. Have to go back on the Monday with parts and explain why my cost pretty much doubled. He was cool with it after but Advil had a job on my head after.
