underground gutters

hello all

just brought a house and i would like to burry one gutter underground.

question how far should the gutter be away from the house?

one more question, i cant tie into the street system so where should the gutter drain out and how should it look, should i fill the hole it comes out with stones?

re

I don`t know much about gutters,but I imagine an aluminum gutter undeground wouldn`t work too well,maybe try a piece of schedule 40 pvc pipe to go underground,a bit more durable.

You would use the 4" black corrugated drain pipe for that application. They sell connecters that put your down spout into the pipe.
Bury the pipe a minimum of 6" or grass will have a hard time growing over it.
Run it out into the lawn as far as possible giving the pipe slope out as you go so it will drain.
If your yard has slope it will run off on its own if not then the last 10' of pipe can be the perforated type with a sock to keep out debris and that would get buried in pea gravel. The deeper the gravel the better the drainage.
The latter without a open end can easily get plugged up by debris from the gutters.
Id try to have the end of the drain pipe unburied.

There are also "pop ups" to use on the discharge end if it going to be in a lawn.

Beware about freezing!! - Since you neglected to say where in the USA you were (Florida, Alaska or Hawaii), it is hard to give any suggestions on the ways to combat freezing, unless you divert just before going subterrainian before winter.

I have underground drainage to carry water away and use a pop-up and it works well except in winters with low snow for insulation and protection. It is not a problem with the pop-up. We have a 4'+ frost depth and only had a problem late one year with little snow cover. The roof run-off and some of the late winter and early spring rain showers are very troublesome unless you are deep (I was 12" - 16" down) and 6" could cause problems if you do not have snow for an insulation.

Solid PVC is far superior to the cheap rippled, flexible plastic because it drains faster and cleaner, so there is nothing to freeze in the pipe and no debris.

I agree with Concrete, use rigid PVC rather than the flexible drainage pipe. The small increase in price is well worth the much easier installation and better performance.

If you do go with the donkey-dick use a 2x4 inside the pipe when laying (remove afterwards) to ensure getting it straight rather than a lot of humps and bumps.

I have over 100' of the flex pipe from four downspouts in the ground for ten years now draining over 200' of 6" gutters. In Michigan with no problems/freeze ups ever. By the time the gutters and downspouts thaw so does the pipe. Its buried from 6" to 12" down and the ends are open(with perforated caps to keep out critters).
Every few years I have to cut the grass back from the ends to promote better drainage.
That said deeper is better and I have real nice slope in my yard so I didn't need the pop ups they may freeze easier.
Yes pvc would drain better but the install will not be easier. If your trench is right your pipe will be to.
The flex pipe is meant for this application. Its around and under my basement and my pool and working fine for many years.
