Hello guys, I acquired a 10 years old house last year. As part of the purchase process, I of course proceeded with a water analysis which revealed some numbers outside the norms: [list] [*]arsenic (0.013 mg/L) [*]baryum (1.44 mg/L) [*]TDS (872 mg/L) [*]iron (0.5 mg/L) [*]sodium (204 mg/L) [*]last but not the least, [b]iron bacteria[/b] [/list] I therefore asked the house seller to split half-half with me and install a completely new water filtration system. We picked the local installer with the best reputation. He installed the following: - big blue sediment filter - greensand / permenganate filter - a metsorb filter for the arsenic, by far the most expensive piece of this setup - a water softener Keep in mind that this was my first house with a well, and I knew absolutely nothing about this equipment. Had I known today, I would have picked an installer who instead favors a chlorine-injection system. Too late... The first 3 months were like a dream, perfectly tasting water and no odor. Over the course of the next 5 months, things went downhill. The water have started smelling more and more like rotten egg. Today, enough was enough. I decided to: - completely clean the permanganate tank - clean all injectors - start a backwash and literally sit beside the filter for 1h30, making sure that all cycles were ok (for example, that the brine cycle was sucking enough permanganate, and then filling it back properly) The greensand filter seems to operate perfectly. After testing the water, unfortunately same odor. I therefore decided to put all filters in bypass mode, except for the greensand one. SURPRISE! The water softener is the cause for I'd say 90% of the odor. I'm not 100% sure for the metsorb, it might be responsible for 10%. One thing is obvious: the water tastes and smells perfect when only the greensand is active. The big question #1: is the resin in the water softener now full of iron bacteria? Can I simply disinfect it or this could be a permanent damage? The really expensive question #2: what about the metsorb filter? The media alone is worth 2000+$ CAD. Thanks!

Hello all. We have a slight problem that seems to be getting worse. Our sewage line, exits through the basement wall and leads to the septic tank. Before it hits the wall, it transitions from PVC to cast iron. It's then a cast iron pipe from there, to the tank. My question is, based on the images below, do you guys think that somewhere the pipe has a leak or is it possible that ground water is just seeping in around the pipe? In either case, what sorts of solutions do I have? Sorry for the quality of the picture looking into the pipe. The wall makes it look like water is just flowing out but it really isn't. Today is probably the worst I have seen it and right now it's damp on the concrete floor. Luckily, this slopes slightly to the sump pit.
