Underground drainage for Gutters
Posted on 11/22/20 at 6:33 pm

Looking for recommendations on what to use for underground drainage for gutters. Debating between regular 4 inch PVC sewage pipe or corrugated pipe. Also any tips and tricks for proper draining would be appreciated.

PVC - it will flow better than corrugated pipe.

Either pipe is probably fine.
What kind of tips are you looking for? It's a fairly straightforward proposition:
Downspout either connects straight to the underground pipe, or rests above a catch basin. Pipe then runs to the termination point, usually either into a ditch or to a pop up emitter at the lower grade / street level.
If you're connecting a couple different downspouts to the same drain your trench digging becomes a little more complex but it's all still the same basic idea.

Do you have trees/shrubs nearby where you plan on going underground? If so you would want to make sure you use one continuous piece of the corrugated pipe if you choose corrugated otherwise roots will surely find their way in at the joints since corrugated joints aren't water tight.
The advantage of choosing PVC is that the joints can be water tight if done properly. So if you have to have a lot of sharp turns (corrugated can make slight bends without joints) in the pipe or have tree issues, PVC would be my choice. Disadvantage obviously is PVC costs more than corrugated.

New construction so no trees or shrubs yet. Just looking to get it done correctly before putting down landscaping. Most of the runs will be straight, a few will be 30 feet with pop up drains, others will be 75-100 ft to the nearest ditch.

PVC and you better prep and glue the shite out of the joints, can't tell you how many houses have had ruined foundations, sidewalks, and driveways because of a leak at a failed joint. Don't need more than 4" pipe.

This. It's also difficult to get orrugated pipe to slope properly since it will sag or rise with any low or high point along its path. With Rigid pvc you only have to set your beginning and end elevations.

When it comes to underground drainage, bigger is better. Minimum of 6" all around. I ran 4" for gutters and after getting bottlenecked and backing up water in my yard, I replaced the last 100' or so with 8" gasketed sewer pipe. That sucker moves some water now.

Never corrugated, unless you are selling the house soon. It will lift, clog, and be more maintenance that you need. Like said, sewer pipe will work fine, and it is not expensive.

I did all mine with PVC. I would use the sewer pipe if I ever build again. My down spouts are 3x4. Gutter guy told me to use 4" pipe for single down spout. And go up to 6" if I ran two together. Been working good so far.

I'd suggest a catch basin with some sort of filtering/netting to catch debris. Will help limit the number of times your underground pipe gets clogged with leaves/debris. I would do this even if you have some sort of leaf guard on your gutters

The French drain guru on YouTube recommends corrugated, claiming the turbulence better removes debris. Seemed to be an unpopular opinion.

Solid pipe 4" or 6" depending on roof area per downspout or connecting 2. Possibly 8" for multiple downspouts & long runs.
Add in a cleanout near the downspout connection for maintenance.
Solid pipe makes it easy to see pitch.

This. You can get some decent looking 12x12's at your big box stores. Would make blockages occur much less frequently.
Put in PVC with cleanouts and you'll be golden

I’ve got corrugated. It has lifted up above ground level in a few places, collapsed in another, and wherever they can get at it, squirrels and chipmunks chew holes in it. Don’t get corrugated.
