I would think that for most burps by the device the 5 gallon bucket would be alright, however, if the device ever malfunctioned, you could end up with a mess in the basement unless you somehow pipe the outlet of the RP device to drain outside or to a drain pipe.

This safest thing to do if you are going to put the backflow prevention device in the basement, is to pipe the drain of the RP assembly to a drain pipe or outside or use a double check valve assembly as your backflow device. It never allows water to be expelled. There is a trade off in that the double check valve offers good protection against backflow but not as good as a RP device.<img src=icon_smile.gif border=0 align=middle>

To add to "SprinklerWarehouse Irrigator's" comment. If you decide to install this RP(Reduce Pressure Assembly) in your basement and you choose to pipe the drain of the assembly to a local drain, ensure you have a proper(to code, 2x the dim of the pipe is norm) air gap between the RP drain and the pipe you are using to channel the water to the local drain. Most manafacutures sell adapters which bolt onto their devices which allow for proper air gap. If you decide lean towards the use of a bucket under the divice, ensure you have a proper air gap as well. The logostics behind this is if a back-siphonage was to occur and the bucket was full of water and the RP dump was sumerged in the bucket water a back flow could occur. There is a lot more techincal information out there if you desire to obtain such information. If you need more information let me know and I can get it for you from USC.
