I think the sanitary seal is in the picture; just hard to see, I'll get a better picture this morning.
Well, I'm still going to get confirmation, but I think I might have some sulfur-reducing bacteria as I get a slow buildup of black slimy goo in the toilet tanks, and when guests come over they say they can detect a very faint sulfur smell when water comes from the tap or when they take a shower(I think I'm used to the smell 'cause I can't smell anything). If the water sits for a period of time, the smell goes away.
I was going to look into maybe using some chemicals from Cotey chemicals instead of using the traditional bleach method.
The only test results I've gotten thus far all show good quality, but I need to do some additional tests. i.e. Manganese, Sulfates, Chlorides, Hydrogen Sulfide.
