I have a dominator bowl and changed it to a lube fitting on the back. Due to the fact with water as a lube from the pump whatever the pumps suck up such as sand paper,plastic it will go out the rear shaft and eat up your shaft and bushing. Do yourself a favor and have a lube fitting installed will save you money in the long run.
