Drain tile question

[cnymowing]

I have a customer that needs a retaining wall, about 4' tall, 30' long. He also wants to have two down spouts tied into drain tile, along with his pool backwash tied into pipe.

I was wondering if it is possible to tie the downspouts and backwash line into the section of perf pipe that will be behind the wall, or if doing that could somehow undermine the 57 stone behind the wall with the velocity and volume of that much water?

I'm leaning towards just running a solid pipe for the spouts and backwash along with the perf pipe behind the wall, but I was just wondering what other people's opinions and experiences are.

The goal of any hardscaping job is always to reduce as much damage by water as possible, especially in colder climates. My advice would be to output your drains in another more suitable location, and also to drain your wall with pipe per the manufacturers spec.

Water through the wall will only increase efflorescence, and lead to premature failure of the wall.

I know about the efflorescence, I was just wondering if is possible to tie in the downspouts to the perf pipe that will be used behind the wall for drainage, all the water will be daylighted at the end of the wall, on the downhill side of the property, and the only direction for the downspout pipes to go is the same direction of the drainage behind the wall...

Where in CNY are you from?

DONT do that. The perforated pipe will deposit water from the downspouts behind the wall. Run a solid pipe. Water is your enemy when dealing with walls. Keep it away!

Such a bad idea it would be a major no no, like stated before use a solid pipe run it alongside the perforated pipe.

As said before if you must tie these pipes to tile behind the wall go with solid

Just make sure your solid pipes protrude past the edge of the retaining wall. Thats going to be alot of water coming out of the eaves and especially the back wash. Is there not another acceptable route for the two.
