How does one attach? Hose clamps? Sealants?** A: Our Gulper 220 offers 3/4" hose connection. You may use a hose clamp to secure the hose. **Q: Can you use this for a fresh water pump also?** A: This pump is designed for grey water evacuation. I would recommend our Whale Watermaster pump or Whale Universal pump for fresh water hold tank. **Q: Will this pump manage waste water from the galley sink?** A: Yes. I would highly recommend to have a sink strainer so that solids are not running down the drain to the pump. Otherwise, a great super reliable pump! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Isolate first *by M***L on 16 February 2020* So efficient it nearly took me down the pities brilliant no more flooded bathrooms.I need to find the timer codes for the main control box now for the auto stop!
