Proper drain pipe size. (Off topic)

I am running my downspouts to buried pipe to be piped away from my house. T he side I am working on has two downspouts. I am also adding about 5 small atrium drains. The underground pipe that will lead to daylight will be abou t 70 feet long. (This is not a straight run, there are curves as I am going parallel to the front of my house, turning, then going parallel to the sid e of my house.)

In that 70 feet, there will be approximately 17 inches of drop.

What size/how many underground pipes would you recommend?

Bigger is not better in these cases, a 2" pipe will be more than sufficient.

A 2 inch pipe for each? Is that what you mean?

2" coming off the downspouts and 1" off the atriums. All can be joined into one 2" trunk line to the end of your 70' run. You can run a larger diameter pipe but the downsides are, the water flows slower leading to a higher chance of dirt/debris clogging it, bigger is more expensive, and of course critters just love making nests in those pipe tunnels.

It's also a good idea to have a couple of Y clean-outs so that you can use a hose to blast some water though the pipes to keep them cleaned out once a year or so.
