Radon mitigation discharge pipe
 

Our radon outlet pipe ends in a down-facing elbow, above the 2nd story
roof. When I installed it, I put a screen over the outlet, thinking to
prevent bugs and birds from nesting. In recent bad weather, the screen
got plugged with snow, stopping the discharge. I pulled the screen off.
Now, I'm wondering whether a screen is necessary. The airflow is fairly
strong, and cool in the summer, which I think would discourage bugs.
Birds, ... who knows?

If anyone has experience in these matters, I'd appreciate hearing.

Thanks,
George

No experience with radon mitigation pipes-- but I know Mr. Murphy and
his law all too well.g

Sure as heck, as soon as that screen comes off, the fan dies and
critters start lining up to get into your basement.

I would use 1/4" hardware cloth as a fair compromise between critters
I could handle in the basement and allowing a free flow of air.

I just had a thought-- how did snow block it? Presumably there is a
fan blowing air that is likely at *least* 25 degrees above freezing.
Am I mistaken in thinking that those radon fans blow continuously?
If your basement is colder than that- you might want to address *that*
problem.

I left the screen off of a dryer vent one time and a few weeks later the
flapper that should have closed to keep the air from backflowing into the
dryer didn't close. I stuck my hand up and into the vent to see what was
blocking the flapper and promptly got stung for my trouble. Wasps had moved
in and weren't happy with the invasion. Lesson learned.

How about installing the screen a couple of inches up into the elbow?
That should protect it from snow.

I don't know about the radon vent, but I found it very
curious that the install manual for my Rheem condensing
furnace says that you can't put ANYTHING over the
2" vent pipes that extend outside. Apparently the concern
is the effect George described, ie snow/ice freezing up
over any screening. The obvious downside is that there
is a free and open route into either the exhaust or intake.
The latter would allow a rodent into the unit compartment
with the wiring, gas valve, etc. It would seem to me the
risk of something bad happening, including blocking the
vents without some kind of screen, is at least as great as the snow
problem.

With the furnace it makes sense, as that is an intermittent airflow
[and very moist airflow, to boot] . But am I behind the times
thinking a radon vent runs 24/7?

Years ago, I got a call to a house with no heat.
The problem turned out to be that mice had
come in the exhaust vent tube. They got into
the furnace compartment, unable to escape.
They turned thier attention to chewing wires,
and that stopped the furnace from running.
The dead mouse smell was overpowering.
Really awful.

They don't take air from your basement, rather from under the slab. If
a critter were to crawl down one, they wouldn't end up in the basement
(see: sentence #1). There isn't a lot of air coming out of these
(see: sentence #1).

But there is always some leakage from the basement into the radon
exhaust system, and that means there is some place some small size
critters could get into the house proper.

Just a thought.
Add a reducer (expander) to expand the end of pipe to 4", put screen
over that. Glue the pvc part on to pipe, or just add a sheet metal
screw or two. Use a coarse screen. That way you got more surface area.
I'm guessing you now have a 1.5 inch pvc pipe. I dont know anything
about radon piping.
1/4" hardware cloth will keep birds out, but not bugs. Better than
nothing I guess..... A 1/8" screen would be ideal, if they make such a
thing.

The expanded pipe should shed snow better too.

There shouldn't be any such leakage. Nope, not if it's installed by
anyone with more than a single-digit IQ. The pipe should be
completely sealed from above the roof to below the slab. The system
won't work if there are leaks. The whole idea is to pull a partial
vacuum under the slab.

You're right but there isn't much air flow. The idea is to pull a
vacuum under the slab so any radon under the slab will be pulled out.
I'm not sure there would ever be enough moisture to cause a problem,
though.

If the OP has a fairly strong air flow as stated, I would bet my
pension there are some leaks somewhere. Radon just doesn't come out
of the ground that readily. The vacuum sucks air into the system
from all the cracks around the basement floor and walls, bringing any
radon oozing thru the dirt along with it. If there were no leaks in
the foundation anywhere, there would be no way for the radon to get
into the basement, it would just flow around the foundation and work
its way into the atmosphere all around the sides of the basement, and
the OP wouldn't need an abatement system.

I always loose OP. I don't understand how it could plug. Warmer air. I was
going to screen mine since my radon level is low in summer and fan turned
off. Of course, my pipe goes up inside the house as I installed it. Don't
know how OP is placed. I only used 1.5 inch pipe, works fine.

Strong flow might mean anything. Radon leaks through cement, even if there
are no visible cracks. The amount of airflow is also dependent on how much
free area there is around intake. A large pit of large rocks can pull a
bunch of air. If soil is water saturated, flow will decrease.

Irrelevant. The statement "there is always some leakage from the
basement to the radon exhaust system" is false. There had better not
be, or the system won't work.


Radon just doesn't come out of the ground that readily.

Define "that readily".

The vacuum sucks air into the system
from all the cracks around the basement floor and walls, bringing any
radon oozing thru the dirt along with it. If there were no leaks in
the foundation anywhere, there would be no way for the radon to get
into the basement, it would just flow around the foundation and work

Wrong. Concrete doesn't form a hermetic seal. That's the whole
problem. The solution is to get rid of it *before* it can percolate
through the concrete. Give it a lower resistance path the the outside
air, than through the house.

Again, there should be NO WAY for an animal to get down the pipe,
thought the pump, into the basement. The thing would have to be
broken off.

Have you ever actually seen these things?

I tend to agree it was frozen moisture. Snow could not get on the

The rain gutters need to be cleaned anyhow.....

This isn't a given. I've cleaned very few gutters in my life. The
gutters on one house don't need cleaning and the other doesn't have
gutters. In fact, the previous house only had one small section (15')
of gutter that ever needed cleaning and that, just over the garage
(easily reached with a 6' step ladder).

You generally don't have to climb on the roof to clean gutters,
either.
