I dropped off a G.R.I pump that wasn't working and although the quoted me a very high price to replace both bearings and get the pump running, I figured it would be cheaper than buying a new pump. When I picked the pump up it worked once again, but when I got home, I noticed the fan on the back of the pump and the inside of the fan housing were encrusted with a 1:4" of packed on dust, this is probably the initial cause of the pump failing in the first place, they just replaced the bearings and charged me $184.00 and left the air vents clogged and caked with funk, it would have taken a 2 year old 30 seconds to blow out the housing before reassembling, this made me drop my review to 1 Star.
