Not an issue in my pond. The bottom drain empties into the side of a
55 gallon barrel and the pump sits in the third barrel.
If this is a concern you could put the pump in a bucket. Allow the
water to flow over the rim of the bucket and be picked up at the
bottom by the pump.

Regards,

Hal

For those of you with a bottom drain...how do you protect yourself against
emptying your pond if there is a failure somewhere upstream from your bottom
drain?
