Odds are you are OK. If you wnt to be on the safe side go to the drug store/grocery store and pick up a gallon or two of distilled or RO water. Starsan lasts for months mixed in with that stuff.
The other concern would be do you want to brew with the cloudy water. It should clear up after it has been run a while I would think. They just stirred up some sediment in the pipes when they worked on it.
