**Q: 1) If I wanted to use a garden hose what kind of attatchment do you recommend?**

A: The CDU790 is a sump pump designed for residential, indoor, ground water only, sump pit applications. We would not recommend using any sump pump continuously or in a pond with aquatic life. Thank you.

**Q: What type of water hose would be best for emptying a spa?**
A: Thank you for contacting us with your question. This unit is not for spas or pools. This unit is only for removing ground or rain water from a basement sump.
