Review for: Little Giant WRS-6 (506055) Drainosaur Water Removal System, 5 gal.
"This pump does a nice job the pictured configuration seemed to show it installed directly under sink drain however the inlet is located on the side of the container. Made for a different install than planned. Would be nice to have received more 1 1/2"" fittings rather than a couple 2""(overkill) and only 1 1.5"
