I have a saniflo macerator toilet system and when flushed, the pump does not immediately come on and the water level rises up pretty high. only then the pump comes on for a second or two but the bowl does no empty nor does the water drain out

Did you put an 1 1/2" vent pipe? It must be vented to the open air. Air must flow in and out of the vent pipe at all times so it can work properly. I had the same issue but after removing the cheater vent from the vent pipe it solved my problem. They do not recommend using an air admittance valve, cheater or mechanical vent on the vent pipe, as it only allows air to flow in or out.
