Master plumber in Ma & NH
Your water heater is filled with cold water from your supply so it is most likely already filtered ..Hard water will build up on the dip tube and heating elements in your water heater and start scaling off ..it will look similar to sand ..Put a garden hose on the bottom of your water heater and open the valve , this will flush it out ..you may have to do this a few times a year depending on the quality of the water ..Make sure the water heater is turned off before you do this .. Any cartridge type water filter out there will filter out sand ..
