What is the white material in the faucets strainer?
The cause of this could be from the disintegration of the dip tube in the hot water heater, as some dip tubes have been known to corrode and fall apart. There is a little known problem that is just starting to become recognized, water heaters made in the 1991-1996 range are particularly susceptible. If you notice this material in the aerators (strainers) of your faucet, there are two paths of action that you can take. 1. The remaining dip tube can be remove and replaced. 2. The hot water heater can be replaced.
