Replacement impellers unavailable By Colin on 8/26/2015Colin wouldn't recommend this product to a friendReactor worked fine for 6 months until the pump became very loud. Pulled the pump and it was clear why. The Impeller pin was worn so far that the impeller was making contact with the impeller housing and making a racket. Tried to order a replacement here. Not available! Contacted customer service and they said it was still in warranty and got me one out very quickly. The only problem is it wore the pin out again. This time OVERNIGHT. Contacted Customer Service again but haven't heard back. In short why would you buy a product that you cant get replacement parts for.
