When you slid the fernco up you will still have a stub to pour water into. No need to have the cover up 2 feet to get it out of your way. And if you use the mason line technique there would no reason to remove the cover to check the pump.

Be sure and use ferncos in the pipes just above your sump pit cover so you can easily get into your sump pit for pump maintenance. Drill a small hole in the cover to allow you to run mason line attached to your pump float to allow you to periodically check your pump is still good.

My first question is:How did you gain access to this forum. This for radon professionals who subscribe to AARST.
Call your State or local Health Dept. and have them recommend a certified radon mitigator you can consult. And Please, stay away from the internet.

Please maintain this site for its intended use. Your political opinion is neither welcomed nor helpful to fellow mitigators. Thank you.

That’s a question better left answered by her Doctor. I’d stay away from that discussion.

Brian,
You hit the nail on the head.
Most of the similar construction we have discussed here had a bad mold problem behind the FRP curtain insulation that I witnesssed.
One home literally had it's PT wall board almost down to wet cardboard consistency from foundation water.
In all cases, I made the problems known to the homeowner. That's just me. I suppose this would make a good ethics topic on another thread.

Use the sump pit for your vent location and you’ll be fine. If you can’t use the pit, core your hole over the top of the perimeter drain at your chosen “vent out” location. Suck out enough stone with your shop vac to expose the drain pipe. Cut the top of the pipe off and install your vent and complete your install. Seal the sump.

Have done several. All have had concrete slab, not wood floor. I use Fantech FR150 or Radonaway equivalent. Never a problem. Always plenty of crushed stone in a wood foundation design. Radon mitigator’s dream.
