: I have a gas water heater and small rock like particles are continually being deposited in bath tubs and they clog up my water faucet filters. Im flushing the water tank about 2 times a year. Ive replaced the Water heater outlet valve for full flow. No matter how long I flush the tank, I cant seem to get rid of the particles. Any suggestions?are you sure these are hard water particles. i have reports of some -plastic-cold water dip tubes that are comming apart into little pieces that give the problems you indicate. as plastic floats flushing from the bottom doesnt help much.remove the hot side fitting on top and flush. also remove and inspect the dip tube on cold side. good luck
