Product review (4 stars): The addition of the drain tube seems like a good idea
Overall, the product seems to work well.  It replaced my failing pump at a reasonable cost.  The addition of the drain tube seems like a good idea.

My only challenge was that I had difficulty to get the output hose firmly into the housing.  It snapped fine in and out of the original pump, but seemed like a tighter fit into the replacement which made it difficult to firmly seat it...  I inserted it as best as I could and then used a few wraps of duct tape for good measure...
