Drain the excess stormwater away, not the leaves and debris in it. The 9 in. Square Drain Grate blocks troublesome particles from entering and potentially clogging your drain pipes, while letting the stormwater flow through. Use the drain grate (also known as a drain cover) to drain moderate flows from lawns, landscaped areas, patios, walkways, and under downspouts. The 9 in. square drain grate has an open surface area of 28.4 sq. in. and a flow rate of 87 GPM. Connects to the Spee-D Catch Basin Drain, 6 in. sewer and drain pipe & fittings, 6 in. single-wall corrugated pipe, and 6 in. Sch. 40 pipe for a soil-tight fit. The pipe grate is ADA Compliant. Built to stand up to the elements, it's made of polyethylene, a type of plastic, using a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking from the sun. As part of a complete drainage system, the grate drains water while preventing leaves and debris from entering the drain pipes. The pipes carry the water to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. Start now and find the right drainage grate for your project with the free NDS Home Drainage Center tool at ndspro.com/home-drainage. NDS, founded in 1972, is the preferred choice of professionals and the leader in stormwater management solutions with proven products, tools, and support to help you get the job done right.

A: I doubt it will work. It is basically the lid for a 9 in. x 9 in. Plastic Square Drainage Catch Basin in Black, 2 Opening Kit. This catch basin connects to 3" or 4" PVC pipes. Most drain systems use 4" mains. You may need to go to a specialty house for 8 inch lines...

A: The catch basin can be beneficial if there is a lot of debris on the roof, maybe from trees. The grate will filter out much of the larger debris and prevent it from going down the drain line.

A: This drain cover would cover you drain, but it is designed for a 4 inch drain pipe. You could try it, but I would be reluctant to step on it. Plumbing Supply has a 7.25 inch cast iron cover online. Go to the prodesk at Home Depot to see if they can order a cover for that size of drain for safety.

Q:Will this product work for an outdoor concrete floor?

Answer This Question
A: It is very common for these grates to be installed outdoors in concrete floors. You will want to have this sitting in a sewer and drain coupling that is placed on top of the drain pipe. Cover the top of the grate with masking tape to prevent concrete from getting in the pipe. Pour concrete, remove tape, and smooth concrete around grate. This grate will support pedestrians walking on this. If heavy wheeled objects will be rolling over the grate, it would be best to cover the grate with a piece of plywood before rolling over the grate.
