Installing grinder pump and pit. Should i do this???

I'm having my house which has a 2 bedroom apt hooked up to city sewer from my septic tank. The waste water run is about 350ft. They have put in a pit with a huge grinder pump and ran the 2 inch pipe about 350 ft out to the city sewer. I have asked before they started to put in clean outs so we have access if the line gets clogged. They told me today that I didn't need them on this system. Is that true or did they forget to do it and should I hold out on last payment until they are installed. Also there should be check values to keep water from back flowing back into the pit correct? should I ask about that or is that a standard thing. Yes my township has been here a few times checking on the crew so far. I'm questioning because it's a lot of money and I of course want it right the first time.
By the way I'm new to the forum so I want to say thanks for allowing me to post.

I don't know how many cleanouts you want but 350 feet is a long way for just one to the point it might be largely useless. For that long a run and carrying effluent that's already gone through the pump I would consider going without a cleanout. If you do go with cleanouts I'd put them no further than 100 feet apart and make them bi-directional so a 50' long auger can reach everything.

You didn't mention anything about elevation so I don't know if a check valve would be needed. Check valves are one more thing that can fail and are a good clog point so I'd go without if you can.
