Patio and Driveway Drainage Solutions – Low Profile Drain (Part 1)

Just about any place in need of a drainage point can use catch basins (or one of their many variations) to evacuate water. Homeowners can use catch basins for driveway drainage, pools, patio point drains and landscape area drains. And, the installation techniques employed will be as diverse as the application.

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 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.

The Next Generation Basin by NDS

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.

The Catch Basin Medley: Know Your Options

buy plastic grates online, buy 5" plastic grates, buy nds drains online, 5 inch pro series buy nowThe size, shape and material used to make a catch basin vary based on its intended application.  Round plastic catch basins are smaller and usually found in residential applications while larger, cement basins are used for heavier duty projects.  Many residential basins – even those on the larger side of the scale – feature optional decorative grating to make a potentially ugly drainage product look more appealing and less intrusive.

Over time, our sister blog has written several useful articles on the applications, sizes, installation methods and features of catch basins.  They are listed with excerpts below:

Catch Basins and Downspout Drainage

“A driveway that slopes into a garage can direct storm water toward the house.  Trench drain can be used to remedy this drainage problem by helping to redirect water away from the garage or living space.  However, a big contributor to the water problem can also be downspout water.  Driveways often have downspouts that drain roof water directly onto the pavement.  If the driveway doesn’t slope away from the house or allow for adequate drainage, water pooling or flooding can occur.  This article is about how simple catch basins can help to re-route downspout water…”

“There are a number of options available for landscape contractors and homeowners who need a large catch basin.  By large, I am referring to a basin with a maximum size of 2’ x 2’.  A catch basin of this size (2’ x 2’) is at the boundary that separates commercial products from residential products.  Basins larger than 2’ x 2’ are generally made with the intention of being exposed to heavy traffic.  This article will be discussing some of the “large” catch basin products available for residential application…”

 Residential Downspout Catch Basin Installation

“I like to think of a catch basin as the “first line of defense” in cleaning up rain water and drainage pipes.  It is common for homeowners to put their downspout water into a pipe that then travels out to the street or a back yard location.  This often leads to clogged drainage pipes.  Over time, leaves, sticks and sand particulate from roofing shingles will build up in the pipe to gradually reduce drainage efficiency.  A catch basin helps to reduce this problem in two ways.  First, the grating that covers the basin filters out the coarse debris that finds its way through the downspout, thus “catching” the biggest contributing factor to clogged drain pipes…”
