I would recommend that you drain the water out of your water heater, and any other water appliances prior to using it. The water is going to look nasty for a bit because of the gunk in the pipes.

It may be prudent to run a load of water through your washer too... some of the rust particles from the pipes that they were working on will work their way into your home plumbing.. and that will cause some really nasty looking laundry if you don't do that.....

Just some suggestions...... :D

TY Cheyanne! Will do..
