I bought a Little Giant waterfall pump for less then $40 and there have been no issues with Stoddard solvent. Why is the one Grainger sells $100+?
Northern had 2 available when I got mine and not alot of price difference, I got the "bigger" one; and I am glad I did.. Mine too is "Little giant" brand as was the burnt out one that came with my Safery Kleen tank...
which I bought from a private party, not rented so calling SK and expecting them to replace it was out of the question though when I needed a new light fixture I stopped by a shop with a SK truck sittin outside and the SK guy gave me one no charge, and no Qs asked... yeah it was used, but it still works fine several years later
you might see what they can do... dont call the distributor catch a route guy while he's out and about... he may be able to sell you a new one, reasonably
