Does the pipe need to vent above the roofline? Why not just go up to a height up the wall and turn the pipe down?

The problem I see with this system is that since there is no vapor barrier (didnt see any gravel, wwm / rebar....may be they have fiber in the concrete) then we all know concrete will crack even at control joints and radon gas can still come up between the cracks. Radon mitigation system in our area runs between $1200 - $1800..... I suspect this cost more.

I just installed a new fan and it’s reading 4+. It’s also extremely loud. Any suggestions?

Looks like your electrician wrote on the wall in sharpie. Painter is going to be mad.

Help me understand, you connect downspout “piping to that fitting? And if so is that to eliminate the look of the schedule 40 pvc…?

I’m a resi electrician and we all hate having to wire gaydons. When the gaydon guy shows up I take my paid break cuz they always bitch about the most stupid shit.

Radon in your soil which is everywhere does not have enough radiation to decrease your normal life expectancy. The radiation is not lethal. This is a waste of money. The US used to make flatware with radon. The sun emits more radiation that will harm you more than radon.

Do yourself a favor and add a rain bypass for the motor.

First comment/ question, and it is probably a stupid one at that lol. Ok, so i remember learning some stuff on radon when i was young. Is radon a gas or a radiation? Can radon cause bad health issues? (If so, what are we talking about in regards of types of health problems? Lung and breathing issues? Cancer?) Is it garuenteed the house will have radon if the basement is dirt floor and old stone wall foundation? (Like i remeber hearing even concrete basements can have radon if a crack forms in the cement pad in the cellar) Thanks ahead of time and appreciate any info 👍. Interesting video btw.

What core system is this ?

The radon mat prep is the same regardless of single OR multifamily, FYI. You can use this video to train for either.

While still relevant, this video has some fittings that we now have better, less expensive versions of. Please watch our video on Alpha86 products next. kzbin.info/www/bejne/oZSZm2Vuma-VjK8si=XWNOFovGnQ8ZfYim

This is a super helpful video. Thank you!

In my area we put a vapor barrier of 6 mil on the earth then gravel before the slab. Where do I install your new pad ?

Greetings from Colorado Springs. My fan may be undersized, so I'll give you a call.

My manometer is reading 4, is that high?

Thanks for the video. This helped me figure out how to install the alarm!

This was so helpful and easy to understand

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.

PVC pipe above the fan would be a better choice rather than thin metal. That thin gutter pipe is going to make a lot of vibration noise.

You do not place gravel under slab in Colorado ??

@7:54: No backfill (e.g., pea gravel)?! Just an empty hole?

@6:24: Oh, my friend, do yourself a favor and pre-filter all of that dirt with something like a Dustopper. Good lord.

@0:57: "Enjoy"? Wow. That's some sales talk. :)

you should link the series in your discription

Love the video. It seems you didn’t back fill the hole with River run gravel as most do?

How are these explained on gas operated guns ?

What number is the good number? My meter reads 1 inch out of 4. Is it enough or need to be higher?

A Hydro Separator can be purchased where?

nice🙂

what is the unit of numbers on the tube

Not much detail at all. The guy talks fast and is difficult to understand. and how did you choose the riser locations?

My installer attached one outside and the rain washed it out; I'm installing a new one, how can I make it weather resistant?

What’s that liquid called?

A higher U tube reading, means MORE suction (resistance in inches of water column pressure) and LESS airflow. A "good" U tube reading is above zero but less than the fan's capacity. Typically 1" or less means great airflow. Familiarize yourself with Radon Fan curves here: radonpds.com/how-to-articles/

Is there no need for vapor barrier on top of the soil mat to extend pressure field?

Any concerns with water pooling at bottom end of intake pipe causing decreased air flow? And if so how to know? (Yes, we have a sump well that goes four feet below basement grade). Thanks for comments
