I have the BH 2700. Came home to a disaster today. I have been in the hobby for 30 years and always install redundancy in my tanks. However, never thought this could happen. The pump has been running for only 2 weeks! Pump was seized and impossible to touch with the heat coming off it. Im thankful it did not burn my house down. Water was leaking everywhere from the intake and outake where the metal housing couples with pvc fittings Since the heat will expand the PVC fittings. Pump is 5 ft below tank in an open steel stand. I dont think the metal housing of the BH2700 agrees with connecting to PVC. I am so disappointed, reeflo is closed for the weekend. Water is everywhere, my floors, carpet, furniture.
