Unlikely... most of the DDC's that I've had come back were malfunctioning due to improperly manufactured/attached impellers that were making contact with the impeller housing ceiling (of the stock top) at certain angles of impeller deflection (basically, the impeller's surface was uneven due to high spots). I've had maybe three come back that 'burnt up' and those failures occurred within the first week of operation (or less).

Granted, this is still something that Laing is looking into, as they also offer a 1/2" straight inlet part for the DDC pumps.
