Make sure of the following:

ALL water pumps are on
ALL faucets, shower heads, toilets, cockpit shower, etc. are wide open, both hot and cold sides running (remove faucet aerators to speed this up)
MAKE sure the hot water heater is not bypassed and is wide open with water flowing through it (water heater OFF obviously)

Stick a hose in your water intake on the deck and let the everything flush till clean. The pink should disappear fairly quickly. Toilet pink will disappear shortly once you start flushing it a few times.
