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

You would have reduce the 1 1/2 cvp pipe down to about 3/4 then attach threaded cuplin to screw the hose on. Reducing it down, don't know if hurt the pump.

This sump pump come with check valve ?

This pump does not come with a check valve.

what kind of life would this pump have in a koi pond that runs 24/7 365. I have a savio skimmer. Had been using a dayton pump, but they are $$$.???

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.

What type of water hose would be best for emptying a spa?

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. We could not advise on products to use with the unit if it is being used in an environment that it was not designed for and would void all warranties. I apologize for the inconvenience. Thank you again, Tina
