Sand coming into tub from pipes after replacing old pipes

[Dearly]

We recently had our galvanized pipes replaced with copper. Now there is a significant amount of sand coming into the tub. I was wondering does this have something to do with the pipes being under the house, and maybe some dirt got scooped up in the pipe or what?

P,S,
It isn't coming out anywhere else in the bathroom that I know of.

Were all the lines replaced? If so then there may have gotten some sand in the lines when installing them. Just run your faucets and it should flush the lines out. The reason your seeing more from the tub is because you get a much larger volume of water through the unrestricted tub faucet.

I'll bet you dollars to donuts that all the screens in the faucet will also need to be cleaned.

In my experience, complaints of sand in the water after a repipe is a result of sediment/scale from the hot water tank as well as a small amount from the old piping. John is right about the tub, and the sediment is more visible in the tub. Havasu also hit the nail on the head with the aerators.
A good flush of your hot water tank (gas or electric) may show you some evidence. Be sure to turn off the tank before flushing and consult the owner's manual for advice on start up and shut down procedure. The boiler drain at the bottom of you tank could get blocked off by sediment while draining and you may need to open the cold supply valve occasionally as well as open/close the drain valve to loosen up the blockage. Most of the time, completely draining the tank and flushing fresh, cold water into the tank with the drain open will show you how much debris is actually in the tank.

Thanks for the tip the sand has gone away.
