Access to Radon Sump

tred

Folks, pouring paths in next week or 2. How do people handle access to the radon sump. Right now i know mine is under the subfloor and coming out under the raft at corner of the house. Do people usually then create an access gully say in path in case a fan is needed down the line to access it.

Usually from the pipe coming from the floor, externally, put a 90 elbow from the pipe and then bring 4" wavin up to path level, allowing for the cap, which should be noted as Radon sump.

Would it be finished flush with the path, and the cap sealed and weather tight i assume

Would be finished flush if you cut the 4"pipe up the correct length...:D:D

But seriously, yes, and the cover usually is a standard one available in any builders merchant. They are screw fix caps usually and have Radon noted on it. Just make sure and elbow close enough to the wall so as to allow for any possible future vent you may need to fix (bracket) to it.

Thanks, reason i said flush, was in case it needed to be raised to connect a fan too

Thanking you sir.

Finishing flush is fine, and perfered.
If you need to connect with a fan, you can get a push in connection that fits in to the end of existing pipe.

you are right to be worrying about these things now

+1, and don't terminate the pipe beneath a window - if you need to put a riser onto it at a later date.
A good location is an internal corner if you have one.

Yeah , in fairness the previous guy had located the sump in an ideal position. We got a Radon cap and fitted in place. It has 4 screws that allow you to take a cover off, and fit a fan down the line if needed.
