Product review (1 stars): If you need the pump you're kind of stuck - like I am - but a true review on this ...
This pump failed after 4 months of use.  I've had to replace it three times in the past 24 months.  The one before this last 15 months but this last pump only lasted 4 months and the seller won't replace it or provide any credit.  If you need the pump you're kind of stuck - like I am - but a true review on this part says that it's a piece of garbage that will fail before it's 18 months old.  Again, this was the THIRD time I've replaced this pump and now have to do it again after just 4 months.
Update:  Pump purchased in March, 2016 - failed in July, 2016.
Pump purchased in July, 2016 just failed in November, 2016.
These things are a piece of garbage.
