Patio and Driveway Drainage Solutions Part II – New Catch Basin Drain Grate Options

We left off our previous blog after after introducing standard grating options such as the plastic slotted grate and the painted black iron grate.  The neat thing, though, is that multiple grates fit the 12″ x 12″ size profile adapters and catch basins.

Three new grating options recently became available to the market, which open up the design possibilities for every budget. Now there are designer grates available in plastic, cast iron and reinforced stone.

Designer Plastic Grates by NDS

Earlier this year, NDS came out with two new grating designs that are expected to replace the standard plastic slotted catch basin grate. Their Wave (left) and Botanical patterns (right) come in four colors and fit the 12” x 12” catch basins and low profile adapter for both NDS and ADS products. They are interchangeable. The price of these designer grates are a few dollars more than the standard slotted plastic grates. This allows for the affordable replacement of existing basin grates.

Decorative Cast Iron Grates by Iron Age Designs

Iron Age Designs has been around for a few years in the designer cast iron grate market. Their 12” x 12” catch basin grating options, designed to fit the NDS 1200 basin series, are top notch.  Coincidently (or by default), they also fit the ADS and Old Castle 12” catch basin product lines. These grates are strong enough to use in a driveway drainage application. They will easily support the weight of a delivery truck or car. Expect to pay over $100 dollars for one of these grates. Also, expect years of enjoyment from one of these grates being an heirloom in your outdoor living space.

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.
