Previously, this blog has had posts about catch basins for residential applications. These centered more on downspout drainage options and catch basin installation. There are many more applications where catch basins can be used around the home. Just about any place in need of a drainage point can use catch basins (or one of the many variations) to evacuate water. Homeowners can use catch basins for driveway drainage, pool and patio point drains and landscape area drains. And, the installation techniques employed will be as diverse as the application.

An interesting variation of a catch basin is the low profile adapter. This is truncated, or shallow housing that is designed to accept a standard 12” x 12” catch basin grate and allows for direct connection to a vertical drainage pipe. These drains are similar in character to single point floor drains used inside the home, but without the flanges and waterproofing features. They have no reservoir to collect debris from the run-off water. They simply fit on top of the vertical 3”, 4” or 6” PVC drain pipe that is part of the drainage system (shown below without grating).

There are at least three companies that manufacture a 12” x 12” low profile adapter: ADS (American Drainage Systems), NDS (National Diversified Sales) and Old Castle (Formerly Carson Industries). All three companies have slightly differing product designs while maintaining the ability to accept a 12” x 12” x 1.25” thick grating. Two of these are compared below. At first glance, the ADS and NDS low profile adapters seem the same. And, from a strictly drainage functionality aspect, they are.

Both products have a similar dimensioned housing to carry the grate. The grates used in each drain are actually interchangeable. Each product requires a twist-in adapter (3 – 4” and 6”) to interface with the drainage pipe. Both are black colored. Even the company acronyms are darn close. ADS? NDS? What’s the difference?

There are a few subtle differences between the two low profile adapters that become apparent when you hold them. The ADS product is made from Polyethylene (PE) whereas NDS makes their product from Polyvinyl Chloride (PVC). Parts made from polyethylene are a little more flexible and durable than PVC parts. PVC is easier to crack or break, especially in cold temperatures. But this characteristic may not have any bearing on longevity or performance, especially when the drain is installed in concrete.

The flip-side of that material analogy is that PVC, being a slightly stiffer material, gives the impression that the NDS product is a well designed, cleaner fitting drain body. Of course, the ADS drain body has the same design quality as the NDS product. However, the flexibility and feel of polyethylene may give an impression of it being an inferior product. This is certainly not the case, however.

The pipe adapter is an important part of the low profile adapter. It is the link between the grate housing and the drain pipe. As we all know, there are many drain pipes that can be used for an outdoors application, depending on the amount of water anticipated. Generally, 3” and 4” diameter pipes will handle the flow of water experienced in a residential setting. The two adapters, shown above, are designed to attach to both pipe sizes, both PVC and corrugated PE. Both adapters work well with their respective drain housing. For higher volume flow applications, pipe adapters for 6” diameter pipes are available from both manufacturers.

When installed in a patio or driveway, the low profile drain will be hidden from sight and the only thing visible is the top grating. There are a number of products available made to fit both of these housings. Each manufacturer has their own set of standard plastic and cast iron slotted grates, which are affordable, functional and diverse. We will discuss more decorative grating options in our follow-up blog.

Over the past couple years we have posted several articles discussing catch basins and catch basin installation. More specifically, we have found ourselves focusing on the broad selection of catch basin products for yard and downspout drainage manufactured by National Diversified Sales (NDS).

This article is devoted to one of my favorite NDS catch basin products called the Next Generation Basin, or 1200 NGB. The 1200 NGB is a unique 12” x 12” catch basin that allows you to adjust the invert elevations of the catch basin without changing elevation at grade (at the grating). No other residential grade catch basin has this feature!

Take a look at the 1200 NGB catch basin kit (above), which contains two open adjustable wall panels. The round openings in the basin’s wall panels are specifically designed to accept one of NDS’s universal outlets.  So, not only are the inverts for the 1200 NGB adjustable, but it can fit a variety of piping options, too.  In the photo below, a 1243 pipe adapter is shown alongside a panel wall.

If only one outlet is needed for the catch basin, the 1266 plug adapter can be inserted to seal up the wall.  NDS also offers a solid wall panel (or plug side) can be inserted to close the open side (see photo below).  Still, the plug side does offer a knock-out for a pipe adapter if you later change your mind about having an outlet at that location.

The 1200 NGB system was developed to make catch basin installation easier and more convenient. You can see in the photo below that it has three snap off side-outlet options, each changing the slope of drainage slightly. The lowest setting eliminates most sitting water from the basin, leaving less room for a sump to catch debris but draining the quickest. The center setting is the standard and connects with the middle of the catch basin. The highest setting gives the catch basin more elevation for drainage that needs to travel a longer distance. Depending on the situation, each of these outlets can be just what is needed to complete the job.

The 1200 NGB basin also gives you options in bottom discharging. In the bottom of every basin is an adapter knock-out (similar to the plug side knock-out), which can attach to solid a PVC pipe that feeds off your drainage system.  By attaching the bottom outlet to a perforated pipe, you can create a leaching system uses storm water to recharge the ground water.   Small “weep hole” knock-outs are also located in the bottom corners of the catch basin for those who are just trying to rid the basin of standing water.

The fourth option offered by the Next Generation Catch Basin is a total bottom cut-out, which allows the maximum amount of storm water to be put back into the ground. As the ground becomes saturated, excess water reaches the pipe elevation and is taken away in the drainage system. Though this option maximizes the water that remains on site – a popular choice among those interested in water sustainability – it is not the best option next to home foundations.

One of the best things about the 1200 NGB system, though, is the amount of grating options available for it. Standard plastic grating comes in 4 colors: black, sand, green and gray. Also, there are bronze, brass, galvanized steel and cast iron options. Below are examples of the  standard slotted cast iron grating (left) and the black plastic grating (right).

Other ornamental cast iron grating options are manufactured by Iron Age Designs are also available for this catch basin. Below are four gorgeous patterns that are popular in patio and downspout catch basins. Clockwise from the upper left, the pattern names are Interlaken, Locust, Sun and Oblio.

These grates fit perfectly with the 1200 NGB.  What makes the designs so fantastic is how each one incorporates a different image of nature into what would otherwise be a simple work of cast iron. The Interlaken Grate on the top left has a beautiful yet strict design; it must be a representation of the solid form of earth.  On the top right, the Locust Grate provides a breezier feel; the leaf patterns soften the harshness of the material until it seems to flow.  With the grate pictured on the bottom left, the Oblio Grate, you can get a sense of water in the concentric circles; the grate is reflecting the distorted surface of water during a rain.   At the bottom right, the Sun Grate exudes warmth and intensity; the sun seems to pop out of the plain background of circles.   Consider painting this grate in bright colors prior to installation.

National Diversified Sales (NDS) is a plastic trench drain manufacturer based out of California.  They have a fantastic selection of plastic trench drain systems that are used in residential and commercial applications.  The 3 inch-wide Mini Channel is popular because its honeycomb design and inexpensive price appeals to contractors and homeowners.  However, a big part of the drainage system’s popularity comes from the number of complementary grating options offered.

The standard grate offered with the Mini Channel is still a 3 foot long plastic grate, which is offered in six colors (gray, white, green, black, red, and sand).  Gray was the go-to color in the past, but customers are now branching out for colors that blend with the hardscaping; sand and white plastic grates, especially, are gaining popularity.

For those with a more discriminating taste, NDS offers two slotted brass grating options.   The 1 foot long brass grates come in a satin or polished finish. Besides being simple, shiny, and elegant, they contain chamfered holes for optional screw placement, which helps keep the grates secured in the channel.

Another option available for Mini Channel customers is decorative cast iron grates.  These aren’t the ordinary slotted grates of yester-year; the cast iron grating product lines below illustrate the beautiful side of a functional product that was previously considered a necessary – and ugly – evil by many homeowners.  (Note:  these grates are shown with a baked-on oil finish unless otherwise specified but come standard in an unfinished cast iron.)

Currently, four styles of cast iron grates work with NDS’ Mini Channel system: the Interlaken, Carbochon, Locust and the Minnione.  There are a few basic differences between these four Mini Channel grates.  The Interlaken is an intricate geometrical pattern while the Minnione has a flowing design.  The Locust pattern evokes the feel of leaves blowing in the wind.  Meanwhile, Carbochon’s open area is only accentuated by its bold pattern.

Style aside, the most noteworthy difference in the grates is length. The Interlaken (11″ long) is an inch shorter than the Minnione and Locust grates (12″ long).  The Carbochon (14” long) outdoes all three grates by inches.  I think the length of the grates is important because it determines what you can do with the design of the run.  Unfortunately, it is often overlooked during the planning stage and leads to extra work later on.

Another difference in the grates is how they fit into the Mini Channel.   Take a look at the photo above. Minnione, the thinnest grate, does not rest in the channel with the same depth that Interlaken, Locust and Carbochon do.  While the other grates are cast with tongues that fit snugly into the Mini Channel’s patented “flying buttress” lip, one gets the feeling that the Minnione sits on top of the drain rather than resting inside it.

The foundry uses cast iron as the standard material when making these decorative grates but also manufactures cast brass, bronze and aluminum grating for an additional cost. We should note that cast iron grates are uncoated (raw) and will form a rust coating over time.  The rusting process, when reproduced artificially to save time, is called a baked-on oil finish.  I find the resulting patina charming.

If your application doesn’t support this view, though, consider painting with an epoxy or powder coating. The powder coating process smoothes out the natural texture of the cast iron grates, giving them a softer, less metallic look.  You can really feel the difference between the painted and baked-on oil finishes; the process encased these grates in paint rather than changing their outer layers.

Let me just demonstrate the difference between the two available finishes in another way.  Look at the Interlaken grates shown below:  in terms of color, they are very similar.  But, if you look closer you can see the different shine, the thickly coated surface of the grate on the right.  It’s been powder coated.  The grate on the left, though, has a baked-on oil finish.   I’ll leave you to decide which one you like better.  For additional information on cast iron grating finishes, visit our “Cast Iron Finishing Options” blog.

Cost is all in a person’s perspective, especially when talking about trench drain products. A simple plastic grate that comes in six basic colors is available for a very low price per foot. NDS’ brass grate, a beautiful, no-hassle solution for those still worried about rust or decor, is the most expensive. The cast iron grates, which add style and variety, come for the more moderate price that falls somewhere in between and have beautiful finish options. They are the true extra mile, the art to efficiency, and are the balance if a cost-efficient and stylish grate is desired.
