Plumbers are some of the laziest people I've ever met. There's something about that trade which attracts the most slothful mofos around. That's why they're all fat as hell. I have never seen one break a sweat, not even on piecework. A plumber is constitutionally incapable of hurrying the fuck up. Or of ensuring his points correspond to the plan.
I'd hit it with a backcharge.
