How does this pull moisture out of our house?

Where is your company based out of?

Great display!

Great presentation, nice tempo, and great mockup!

I moved into my house and got a radon test done. Long story short they installed a radon mitigation system connecting to my sump pump and sealing it. Since then I noticed a ton of water pouring into my sump pump pit. My pump would run every 1 to 3 min. Today I got curios if I could raise the float switch to try to balance out the water level or make it so it didn't run so often. The radon installers cut a 3" hole in the lid and silicone a clear plexiglass piece over it. I removed that cover to watch the float switch. 5 min went by and still it wouldn't pump. Eventually by shear luck I noticed that as that hole got smaller water started running fast into the pump. I then covered the hole again and the water was gushing in.. then lifted it up and the water stopped. It's now been 20 min and my pump hasn't ran, Why is the radon system sucking water into my sump pump pit? When I remove this little sight glass the u shaped device showing suction still shows a negative suction. Is this OK to leave it like this? With the cover off? I don't want my pumps running so often especially if it's not needed. I have since resealed the put cover till I know more. Any advice would help.

Why did special interest groups get to decide what the safe level is. Germany has a higher safe level rating than america and they have the best radiation and anti poision medicine on planet earth.

Very informative video I do have a few questions though... What is the diameter of the PVC pipe that is utilized when dealing with radon? Also, are there different fans for various platforms or would you use the same fan in a slab foundation as you would in a crawl space or other configuration? Thank you in advance.

my basement slab is sitting on bedrock. how would this work?

Why do I see so many outside systems in my neighborhood that do not have a condensation bypass hooked to them? I see your outside display doesnt have one either. Are they necessary in the north-east?

Our Radon meter by Airthings is currently showing 46 pci/l upstairs. Have slab concrete floor in basement with a sump pump at each end. Levels this high may be impossible to correct?

Awesome video! About to tackle this project myself but having a difficult time deciding on 3" vs 4" ducting. I have an 1100sq ft basement slab with corrugated drain tile underneath and on the edges all leading to sump pit that I will be sealing and extracting from. sub slab is a mix of limestone and just earth. Using a RadonAway RP145c and entire run will be only 15' mostly vertical. Seems like in Canada 4" is typical but I see many US installations with 3". My main concerns are 1)airflow and 2)noise. What are your thoughts?

Any need to put an elbow on the top to keep water out from rain or snow? How hard to install the fire sleeve?

I have no garage and my attic is a livable space. Can I run the pipe up through closet spaces in the house and then through the roof with with fan installed outside above the roof? I'm trying to avoid the look of it installed on the exterior wall.

How do you deal with condensation or ice domes that might form on the outside vent?

David, since the pipe is straight up in the air at the roof, would it be bad during a rain storm? Can't you use a 45 degree to curve the pipe to avoid rain or snow from going down the radon pipe?

You seems to cut the 45 degree over the fan instead of using a straight pipe with some room. That is very bad for 2 reasons: 1 - there is still an angle when you enter into the pump which could cause leak easier and 2 - it will makes serving the pump a real hard job, where you will have to change some pipes. The junction box should be 18 inches above ground or higher depending if you have snow. The PVC should be schedule 40, I think you don't mention it. Also, some peoples seems to tell it is better to add a wire rack at the output.

Excellent description. Thank you.

what glue should be used to connect the PVC pipes and pieces for radon?

what is meant by capping test vials after installation of a radon mitigation system?

Great presentation! You provided detailed electrical information for the exterior install, but nothing other than a service light for an attic install. Kudos for being the only install presentation that provided information regarding firewall penetration info.

Do you recommend a rain cap and/or a condensation drainage system for outdoor installations? Thank you!

I bought a house and can’t find the fan. They wouldn’t install it within the walls, would they?

This is the best video I've seen on what a proper installation should look like. I recently had a system put in (in the Northwoods of WI too), the contractor cut corners, didn't pipe around the soffit, and plugged the fan in an outlet. I knew it was wrong, just didn't know how it was wrong. I made him come back to fix it. --we'll see if he does it properly, but I feel empowered to make him come back *again* if he doesn't do it right. Thanks again for this video.

You mentioned the fan has be to in an unlivable space. Could it be installed in a utility room where the current passive system comes out of the slab?

Great video! What if foundation isn’t a slab, but just a concrete lip with a dirt crawlspace?

I look at the manometer from time to time, not on any schedule. Today is see the level is higher on the side with the tube. It's usually at +1/-1, now it's reversed. Maybe it's that way more often, but I haven't noticed. Is there any reason other than a fault in the system that this should happen?

Residential amounts of Radon gas do not cause lung cancer! You would have to live in the bottom of a coal mine before radon gas would harm you. The Residential Radon Gas SCARE is a SCAM by the EPA. Here is PROOF kzbin.info/www/bejne/ioq9mJ-Ln7F4Zrs

Great video ! Wow! Little question: why can’t you have the fans in the basement and go outside through a rim joists (can go up after that). Why the fan should be in the attic or outside ? I will hire someone here in Canada and the code is less stringent (at the moment) but I want something well installed for a long time.

Great video and great mock up. I have a question, in basements built before the 1970s where there is no base rock & literally slab on top of dirt, is there any value in core drilling a pipe down into the dirt? I’m assuming with a 3 1/2 inch Core, one could get their hand down there and remove 12 inches of dirt or so and put in some base rock with the pipe? Do you think that would accomplish anything?

To make the fan more accessible... wouldn't it make more sense to house that inside the home. above the area where you breached the concrete slab?

Noticed that the systems are open on the roof side. How does water collection/draining work in this case? Does that mean this will back up to the crawlspace/slab?

Super informative...thank you

I bought a house with a radon system in it,but i cant find any system monitor and the company who installed it is out of business. I have looked everywhere but the attic. Could it be up there? Are systems required to have the ushaped monitor on them? I would think so. Thanks.

Thank you! We're buying our first house and just got the results of the radon test showing high. Neither of us knew anything about radon until today. This video was extremely helpful in understanding the purpose and options of a system. I'm just sorry we're in Ohio instead of Wisconsin!

18 people don't understand Fire Walls and how they can get de-rated

what is the specific fan part called? radon pipe fan?

Ruff

Thanks for all the information.

I have a ABS 4" pipe next to my foundation well below grade can I use it for radon

Why are you assuming we have a garage?

Im in Halifax Canada and my house tested at over 3000. Do we have to worry about freezing?

Can you drill anywhere on the slab or does it need to be in an specific area

Get this: My new system looks very professional. But I discovered that my fan is upside down!! I was suspicious because a crack in the floor next to the radon pipe is blowing air into the house! It should be sucking down into the dirt. (actually should have been sealed) Next, my manometer says 4.8. (seemed high) Next, I climbed on the roof. My vent pipe is sucking down!! Finally, my radon level went from 4.6 to 6.8! And that's away from the room with the cracked floor. I'm currently testing over that crack. In about 40 more hours I'll get a reading. I bet its sky high over that crack. The installer needs to fix this. Hasn't called me back yet.

I think it would be benificial to explain what the mechanism is in the introduction. I'm more than half way through the video and I dont know if we are removing radon from the atmosphere, or water.

There is nothing wrong with routing a system off a sump pump pit. But doing that limits on where the system can be routed. And, if you have a pump emergency you'll have to dismantle the Radon system first, wasting valuable time, to get in there. Then reinstall the system after dealing with the pump. If there is clay or sand under the slab and no interior drain tile then the pit may be the way to go. If there is interior drain tile or gravel then there probably would be better options considering aesthetics and function.

Please explain why not to go through where the sump pump is.

Sorry for any misunderstandings, but no, the pipe does not go into the overhang "soffit" area. The pipe goes up through the roof, typically the back side, and vents out above it a minimum of 12 inches. You do not want the vent blowing air back into the garage. It would have a high moisture content and radiation level. On an outside system the vent has to be above the gutter also with no fittings on it. I have seen systems where the pipe goes above the roof but then they installed a few elbows on the top blowing the air back down towards the roof and ground. Not good. You also want to make sure the vent is a minimum of 10 ft. above grade or decks and 2 ft. above any openings or 10 ft. from them while maintaining the min. 10 ft. above grade rule.

Have you done any systems which perform remediation using UV light? Any info on that?

Wow, great vid. So when you go through the basement slab it can go anywhere because of the assumed gravel and drainage pipes underneath? Is there an ideal place? Based on saquare footage, how powerful does that fan need to be. (i.e.: 2000 sq ft basement, 6K+ home.)
