Gutters underground... Which piping/combo?

sh40674

Mods please move if in wrong section..

Ok so I'm going to run my gutters underground. I have a square house 864 sq. feet. I have 3 gutters. I am eliminating 1 gutter and moving it to the front, where we are pouring a new patio, for that gutter we are going to run PVC under the concrete, about 10 feet then to either corrugated flex drain pipe to a pop up emitter, or to perforated SDR 35 pipe then a pop up emitter.

The second simply underground with corrugated flex pip to pop up emitter about 15-20 ft away with a pop up or a solid PVC for about 10 feet, then the rest SDR 35 to allow for drainage then again a pop up. My question is...... Flex or perforated pipe?
My main concern is freezing with water still in the pipe... Either way will be in a bed of gravel with landscape fabric wrapped around to keep dirt out... I know the straight PVC with SDR 35 would probably flow better.

Third pipe will be ran the same way

This is the SDR 35, also available with holes all around

This is flex pipe with slits... Concern here is standing water and good drainage

Just go to Quick links to edit.
Pop ups are not going to work if you live in an area where it freezes.
Use soild PVC and run it to day light.

Here they use pop-ups. The problem lies, when the lines do not fully drain out and you end up with a Ice damn at the top, where the air gap is between the underground line & downspout. Probably would be better to use a dry well for the downspouts, or use rain barrels, so that they can recycle the water for plants, not just let it drain out to the yard.

As for the moving of the one downspout, that can cause problems, especially if the gutters are undersized for their roof to begin with.

To the OP, post the depth & width of your gutters, and the size of the downspouts that you have in place, along with pictures, and measurements of the length of runs for the gutters, placement of the patio, size of the patio.

OK I give up- whats a pop up? Is that what my PC's pop up blocker is for?
Seriously though- my soil is so porous we just use splash blocks or a little perf pipe

After reading more online... They will freeze (live in Iowa).. what if I disconnected them in late fall and ran a regular downspout out say 10ft till spring? Then when thawed I could hook it back up? Don't have a yard where I can run to daylight easily...

It's a cap that goes on the end of the line. When water is flowing the lid "pops up" to allow it to exit.

At that relatively short distances, I would run rigid PVC the whole way. Glued joints and you should never have to worry about it.

Seen corrugated come apart on more than a few occasions.

Sounds like one of my yards.
Dead flat, someone pored the slab to low and graded the whole yard to high.
I ended up having my drains run to a pit with an effluent pump that pumps the water out to the ditch by the road.

OK- back on track here. I would us only rigid pipe and I would bury it as deep as possible. If you're worried about ice in gutters or leaders use an ice melt system.
