pump. But it is a bit more involved than just a naive hookup. You need
float switches, pressure switches, pumps, an agitator to stir up the
water and splash it around, an a mechanism to release the sulfer gas
that builds up constantly, vented somewhere safe (and where the stink
won't cause new problems). I'm sure they can be built custom, but you

We ended up adding a SulferGuard system by Kinetico. It has only been
it for one day, but it seems to remove any trace of the odor. The
sulferguard unit is feeding the cold line to the sink in addition to
the RO system. It uses hydrogen peroxide as a reagent to remove the
