I received a request to route downspouts on a house into an underground drain pipe (which does not exist) and out to the curb. My questions are how is the best way to do this, using rigid PVC or the black corrugated ADS pipe?
The home sits above the street level about 3 feet as is the ground level. The length of the home front to back is approxamitely 70 feet give or take 10 feet. The downspouts in question here run along this entire length, there about about 4 in all. There is one downspout at the back corner, one at the front corner, and 1 or 2 in between.
the HO wants me to trench from the one farthest back all the way to the front where the curb is and run these 4 downspouts into a main drain that is to drain at the curb. The front of the house is about 10 feet from the curb where the water is to be dumped on the street.
Is rigid PVC better here, say 4" sloped towards the street using Y fittings? And if so is normal PVC cement ok to use below ground?
Or is the black corrugaed flexible ADS pipe used in foundation drains the best route to follow and use Y fittings, couplings and the "sock" over it to prevent sediment from getting inside?
Any opinions on a good professional installation method are greatly appreciated.
