|In response to Re: red tinged water w/ black particles|
: : : 2nd bath (3 kids) has red tinged water with black particles settled on bottom. Thought it was old water heater, drained, same problem.
: : : Replaced steam boiler and at same time decided to replace 50 gal. with high cap. 80 gal. 3 KIDS.
: : : Same problem exists!
: : A lot of LI (Wantah, PlainView, Smithtown, ETC) water is well water with lots of mineral content.
: : I had a LI and Weschester Licenses and decided to concentrate on NYC, but I do remember installing filters prior to entering the hot water tanks to protect the tanks from mineral deposits being cooked inside the tank and possibly blocking the T&P.
: : I am normally against whole house filtration as why filter water being flushed down a toilet?
: : Have you water tested prior to installing any filters so you know what your up against.
: : Not all LI water I would consider potable no matter what the powers that be say.
: This is an old house and strange things happen.
I define "minerals" as calcium, magnesium etc. and they are in solution until the water is heated. At that time they come out of solution (precipitate) and form scale. There is no filter that will remove that from the hot side of a water heater. You would want to prevent the formation of the scale which reguires removal of the 'minerals' that create it; you do that with a water softener. BUT... your problem is not caused by anything a softener removes unless you have ferrous (dissolved) iorn and/or mnganese cuased problems. Usually black is maganese and/or H2S and hot water only odor is cuased by sulfate, iron and maganese reducing type bacteria that thrive in a water heater when the temp is less than 140f.
Another cause of rusty water and black particles is galvanized pipe or nipples rusting and corroding.
