I am looking to install a channel drain along the edge of my patio as this is where water tends to accumulate the most.

I've watched several Youtube videos on this so I think I can manage it.

I plan on using the t NDS 1-1/4 in. x 6 ft. Slim Channel Drain Kit and attaching to some PVC pipe once I did a deep trench.

I tried calling 811 for them to come and check for any buried lines in my yard, but they haven't gotten back to me.

Any words of advice before I try and tackle this endeavor?

I'd consider going wider. I have two different channel drains on two sides of my pool, one that's 5" and the other slim one like you are looking at. That little one just can't keep up with the rain we get. The slim one was put in first by the pool company where the pool deck meets my back porch. I wish I would've known to go wider.

The other thing to consider is how easy/difficult is it to clean. With the wider ones, you simply unscrew the grate to remove and clean. I haven't figured out a way to do it with the slim ones without cutting.

Ok good to know. I wasn’t sure if the one I linked was able to snap off. But I know the bigger ones do snap off to clean. Thanks for the advice.

Did you lay rocks down underneath? Or just concrete on both sides?

i am in the drainage business (normally dealing with much larger than this) and both of these are dead on.

As you do get to larger trench, you can get expensive. Decorative grates, and things like that. A removable grate will be the single most important thing as far as making this last.

Installation...all i can tell you is that the better the base you put this trench on...the longer it will last. a bad base, i can promise you that this thing will fall off of grade in a few rains. generic garden fabric + sand will allow for a solid base. then it is up to you to be sure it all on the proper grade.

Hope this helps. good luck.

That’s all you use for a base beneath the channel?

In a perfect world you would pour it in concrete. If you do that, the common problem is that the trench moves while you pour around it. Remember, that concrete weighs a lot more than the trench.
