## Questions & Answers

**Q: Are these pump submersible?**
A: I don’t think submerging this pump is recommended. I checked the installation instructions that came with my aerator 800 gph pump and all of them show non-submerged mounting.  There is an application for recirculating water in a live well mounting the pump directly thru the side (with the pump on the outside of the live well) with a intake screen near the bottom and a spray head above the water line.

**Q: This pump can be used inside tank**
A: I have one for my bilge which does get submerged and one for my live well that is in the same area. So it gets submerged also. So they do operate under water. I haven’t used them inside a tank but I think they should work.

**Q: will this pump run in reverse as well to drain my live well**
A: No our Tsunami pumps are not designed to run in reverse.

**Q: Can you plum one of the fittings with a filter?**
A: We do not recommend use filters on the outlets. We do offer strainers for the inlet.
