The “Orange” sediment would make me think that you have somehow gotten the resin from the water softener into the water lines possibly by not setting it up again properly after you shifted it – check the level of resin in your water softener tank and see if you have lost some. If this is the cause of your problem then there is no simple way but to flush it or drain it out by maybe even going to the extent of having to remove fittings to allow the clearance.
