PVC v. corrugated pipe for underground gutters

I'm looking to install underground gutters and originally was planning on PVC, but being that money is a bit of an issue right now I have noticed corrugated pipe is MUCH cheaper, given that I do not have to buy all the expensive fittings associated with PVC.

So my question is, should I?

I plan to place a filter on the down spout, followed by 8 to 10 feet of corrugated pipe and terminate it with a PVC end and pea stone. Is it really worth the extra $100 or so to do all PVC?

Also, if I choose corrugated, what is the best way to attach a PVC end to corrugated pipe?

Welcome to the forums! Using the flexible corrugated pipe is just fine. Make sure it is not perforated. Grass and roots will grow prolifically into the perforations and cause blockages. The corrugated pipe is not sealed as well as solid pipe, but if buries, won't be a problem as water will flow to the least source of resistance.

I use all Sch. 20 PVC with down spout adapters.
It's not sold in the plumbing area at the box store it's in the drainage area.
I'd be installing the screen inside the gutters inside the down spout, not at the bottom.

The pipe Joe mentions might also be with the sewer pipe. It is much thinner then Sch 40 PVC but still thicker than black corrugated pipe. Although I have used the corrugated pipe with no issues.

I hate corrugated black pipe and would pick the smooth schedule 20 PVC every time. I think it's smooth interior is less apt to clog as leaves and sticks can slide right on through. In my home center it's on the edge of the plumbing area and with the drainage products. It usually comes in 10ft long sections and one end is flared so you can insert another section without buying a separate fitting.
