We are searching for Stegmeier deck drains -- 4 inch -- for our deck area. Any recommendations as to where to purchase these drains in the Oklahoma area would be greatly appreciated.

The company would probably be the best source of information regarding suppliers.

Here is a company in Texas that is not too far from the Oklahoma border.

I used a 5 inch NDS drain that I bought at my local Home Depot. I love it and my neighbors who have a 1 inch deck drain a jealous when it's monsoon season. It's NDS #864g, 5 inch x 1 meter box channel drain.

I used the ~6" NDS deck drains as well. If I had it to do over again, I would use some square drains spaced apart in the deck instead. The channel drains are a great idea, but what I found is that during the concrete pour they get pushed around a bit, no matter how careful you are and you wind up with un-straight drains. I have about a 38 ft run and a 30 ft run, and one is straight as an arrow, and one has a gentle "bow" in it and it really bugs me aesthetically, though functionally they are fine.

The channel drains should have been staked into the ground to prevent any movement during the pour. My drains are straight as a string.

They were... The mistake was one side was poured then the other... Pressure from one side shifted em.

Yeah, they are drains, not concrete forms. I was lucky in that I placed the drain against one end of an existing slab.

I spotted it on the one side (too late) and made em pour both sides on the other... so the 2nd came out right.

Does anyone have any experience with the water hog deck drain? Really appreciate all your advice.

I had the Stegmeir deck drains installed. These are like 1.5" and have been through several of the recent PA monsoons. No issues so far.
