d.i.y. radon mitigation?


I have a "french" drain installed around the rim of my basement that leads to a sump pump that pumps the water out of my basement.
Well i just got a reading done of our radon in the basement before we finish most of it and it was a 10, not terrible,but not acceptable.
The radon guys said to caulk the drain line at the bottom of the wall and that might lower the radon levels to acceptable levels. The basement pump guy said that voids my warranty(sp?).
The radon guys plan was to attach the PVC into the sump pump and vent the gas out the wall into open air w/ the Fan.. I can do that pretty easy myself, but i'm looking for schematics and where to buy the PVC inline fan.
Hope someone out there has DIY this before, because it seems pretty easy, I have power there already.
They want 750 plus another 140 for another test...or i hope i can spend 40 bucks in parts and viola...
=Thanks

d.i.y. radon mitigation?


Hey Chris,
I had this done a few month back by a mitigation company. We bought the house from a couple that were being relocated by a company; that company paid for the testing and subsequent system installation. If they wouldn't have I would have done it myself.
The installation seemed very straight forward. The only part that seemed like a bit of experience really helped with was the hammer drilling down to the drain tile tubing. I can only guess I would have made a few extra holes looking for it.
Anyway, all they did was just about what you described. Put a new cover on the sump, drilled down to the drain tile, put up some PVC from the basement to the garage and then up to the fan right below the roof. Piece of cake if you ask me.
I'm pretty sure this is the one that they put in our place. Fantech
Let me know if you want any other info or pictures.
Eric

d.i.y. radon mitigation?


i'm thinking of diy'ng this. i'm pretty sure if i tap into the upper portion of the drain sump it should pull air out of the whole system.
and i think home depot offers a radon testing and send it away. so hopefully i can save there too.

Radon mitigation is very self doable. You just have to make sure that the work you do meets code.

Speaking of which, does anyone know what kind of caulk/foam that's used to seal sump lids? I know it's not epoxy, b/c it does not dry hard. The color is grey, and when you touch it, it feels like spray foam, but it's not. It seems easy to remove.

If the design is external, it must be 2 feet above the roof line, and 10 feet horizontal distance from a window. Also, good practice is to have a dedicated on/off switch.

d.i.y. radon mitigation?


Hi smallcrpt,

I offer a DIY radon kit. There are a lot of so called DIY radon sites out there but to get it done right the first time you need a little direction. I have had numerous jobs where the system installed was not installed to proper mitigation standards or the fan was incorrectly sized for the job. Also with your situation you must be careful not create a back draft situation with the combustion appliances in your home nor do you want suck all the condition air out of the house. So be careful that you don't end up spending more than you need to. I have the materials and the personal direction you need to get it done right the first time.

I know this thread is long-time dead, but would you be able to post these pictures?
I don't understand why they had to drill down to the tile if the tile drains into the sump.
I have slightly elevated radon (5-7) and a water problem in my basement and I'm planning to take care of both at the same time with a french drain that is ventilated. However, I'm a little unsure of how to vent it.

There are a number of videos on YouTube that show how to do it. Parts are also available on-line.

d.i.y. radon mitigation?


dumb question, the code says 2 ft above roof line, what if your roof keeps changing its line? I have a 1 1/2 story house which has many tiers of roofs and no direct up path, and no way to run it inside the house either...

what exactly is 2 ft above the roof line? well i guess a better question is what is considerd the roof line of a house that has multiple height roofs
