    I am installing a utility sink in my basement right next to my sewage ejector pit. My plan was to install a drain trap underneath the utility sink drain then use a PVC wye fitting to connect to the ejector vent so that everything from the utility sink drains in the ejector pit and that I do not need to add another hole to the ejector cover. Is there anything wrong with my idea? What would be a better alternative?

    It will work. It may have some effect on the pump's operation if the water is hitting the float switch. It may turn it on or off sooner depending on when the sink drains.

    The vent is 2" PVC.

    If an ejector pump is similiar to a sump pump then it looks like the vent might be over the float switch according to the pipes leaving the sealed pit cover. If I add a hole to the ejector cover for a dedicated drain from the utility sink do I still need to use a wye and vent the new drain to the ejector's existing vent line? Or is it okay to just drain the utility sink drain directly to the pit without a vent given how close it is to the pit?

    So if I run the utility sink drain (with trap) directly to the ejector pit in a dedicated line do I still need to put a vent on the drain and tie it into the existing vent line?

    You need to run a vent for the sink trap and tie it into an existing vent 6" above the top of the sink.
