Frequently Asked Questions

Q. "How do I know which parts will fit my Dolphin flushometer?"
A. The parts listed here should fit both the Dolphin toilet/water closet flushometer and the Dolphin urinal flushometer - unless the part description specifically states which model it is to be used with. Your Sloan Dolphin flushometer should be marked somewhere along the outlet tube, letting you know which model you have.

Q. "Do you sell the oil the flushing mechanism requires to work properly?"
A. We do not. Oil is difficult and can be dangerous to ship. We recommend you purchase any needed SAE 10 oil locally.
