History: Had my annual furnace maintenance 2 weeks ago. Replaced whole house filter 2 months ago. Added water softener salt 1 week ago. All Ok.
Problem: 1 week ago wife complained of low water pressure in shower. I put in new shower head and it improved. Few days later same problem, plus more: no pressure in shower and all faucets, toilets don’t fill. Opened shower head and faucets: found red/white “sandy” substance clogging screens. (I do not think it is rust) Ran tub, after a while LOTS of this stuff–about 1-1/2 pints worth–came out. Now hot/cold runs clear in tub/shower. Rest of house, NO water flow or drips (clear). Replaced whole house filter again: normal “dirt” (we have a well) on outside, inside clear. Ran outside faucet: sandy stuff for a while then clear–outside runs well now.
Current situation: shower/tub, outside OK. NO water flow in rest of house faucets and toilets. Where does this come from? How to clear out? Please help. Thanks, in advance.
