Can the brine tank from a water softener be installed into the slab of my basement floor? Are there tanks designed for this, so that only the lid is exposed above the slab?

    I've never seen such a thing. I can think of a few problems though. I'd be worried about dirt, insects and rodents being able to get into it. It would also be very difficult to clean, if that ever did happen. It would make it difficult to tell if it was working correctly, not to mention how much salt was in it. There'd be no real place for the overflow valve to go when the float valve eventually fails, and again, you'd maybe not even notice. Given you need fairly regular access to it (eg: you can't really put anything on top of it anyway), what's the motivation for putting it under the slab? – gregmac Sep 20 '15 at 16:33
  • A relatively small utility room means we've pretty much run out of wall space except for right by the softener tank to mount things, and we have some new electrical stuff going in for solar. The solar equipment requires a "safety zone" in front of it by code where you can stand to service the equipment. A sump pit with a cover meets the code for standable area, so presumably so would a "softener pit." However, you've brought up a lot of good points as to why you wouldn't want to do this. – David Pfeffer Sep 21 '15 at 0:44
  • I've seen softeners where the mineral tank is actually inside the brine tank, with the filter head sticking up above, and the brine tank's cover hides the whole thing. They're pretty compact (the size of a large brine tank), so that may be an option for you -- if you can find one. Unfortunately, I can't find any reliable links. There may be a name for them that I'm unaware of. I've personally only ever seen maybe 2 or 3 out of hundreds of softeners I've serviced or installed, so it's also possible they're simply obsolete or extinct. – gregmac Sep 21 '15 at 4:24
