Product Comparison – Zurn Z880 vs. NDS Mini Channel

The Z880 Perma Trench is one of Zurn’s most popular residential trench drain product lines.  Its name may sound intimidating, but there’s nothing to fear from this plastic drain.  It was designed for pools, patios and landscape drainage much like its competitor, the NDS Mini Channel.  Both the NDS Mini Channel and the Z880 are 3” wide at the top, and both systems have similar features that give each other a run for the money.

Channel Body Differences

The difference between the two systems really starts with the channel bodies.  Take a look at the photo above.

The Mini Channel (shown left) has a gray, honeycombed channel design meant to distribute load stress and prevent the system from collapsing.  This design extends to the grate supports, which hang out from the channel walls in an upside down flying buttress.

You can see that the Zurn Z880 (shown right) has a thicker, solid channel body. It is composed of high density polyethylene (HDPE), the same material as the Zurn Z886 or NDS Dura Slope commercial-grade trench drain systems.  The inherent durability of the channel body gives some “street cred” to this little patio drain.

The Z880 channel body also has “ribs” extending from the outer walls that give the channel extra surface area at vital contact points to the surrounding concrete.  The ribs help “grab” the concrete, anchoring the system in place and providing additional strength.  The channel will not separate from the concrete once installed.  The ribs also add flexibility to the design of the system because they serve as cutoff points in the drain that can still connect to other modular channels or outlets.  I’d estimate the cutoffs are every foot.

The walls of the Mini Channel are made of smooth PVC.  The absence of ribbing is advantageous when installing in a paver patio but poses a problem in the long run if you want to install it in concrete.  Without ribbing to act as anchoring points, the drain body can begin to separate from the concrete years after installation.  In addition, water and dirt may begin to flow between the concrete-channel interface, causing the channel to pinch.  To prevent this pinching effect and the subsequent weakening of the channel wall, make certain that the Mini channel grates are always securely fastened down.

Grating Option Comparison

While Mini Channel grates come in a standard slotted pattern, the Z880 grates (shown below) have a more decorative pattern that gives them a classier appearance.  The thicker grate also holds more weight, providing more structural integrity than thinner Mini Channel grates, but ultimately has less open area for water to drain.

Color options for the Z880 plastic trench drain system

The Z880 and Mini Channel systems each offer six color options which are the same with one exception.  The Z880 offers a sky blue grate while the Mini Channel offers a forest green grate.

If you choose the Z880 system, you’ll be surprised to see that the channel matches the grates’ color.  Unlike pool drains by other suppliers, the Zurn Z880 eliminates this “edge line of a different color” that borders the grating.  This gives the system an overall nicer appearance.

Grates for the Z880 system clip into place.  Each grate has several “tongues” on its sides that snap into the channel grooves.  It’s easier than buying grate screws and lock downs, won’t create weak points in the channel structure and can be popped out of place easier for cleaning.

Iron Age Grating Options – Cast iron decorative grating is available for both drainage systems.  Created by Iron Age Designs, the grates are both beautiful and efficient.

The Mini Channel has four decorative patterns that fit the system, three of which are shown below:  Minnione, Carbochon and Interlaken.  Each grate is slightly different in terms of thickness and how it sits inside the channel.   Iron Age cast iron grates make NO accommodations for screws needed to lock down the grate.

So far there is only one cast iron grate option offered by Iron Age for the Zurn Z880 pool drain.  What amazes me about the pattern is that it’s a Regular Joe.  No, really, it is.  I’ve never found out who was behind it, but somewhere along the lines the decorative option for the Z880 drain became a cast iron slotted grate.  Of course, it looks entirely more sophisticated than a standard slotted grate, but it’s something I’ve never stopped being amused about.

One thing that is not amusing about the Regular Joe grate for the Z880 is the placement of its “tongues.”  In the picture above, you can see the inconsistency between the plastic Zurn grate and the Iron Age Designs option.  The lockdown tongue on the cast iron grate is placed too high, which means it probably won’t secure into the channel properly.

I don’t want to sell the Z880 drain short, though.  Zurn does offer four other decorative options, including a bronze decorative grate, for homeowners who want to upgrade from plastic without buying the Iron Age grate.

Whereas, the Mini channel may wear and tear more quickly (especially in regions of freeze-thaw) because of the cellular channel design, the Z880’s solid body design and anchoring points makes it a more rugged product over the long haul.  The Mini Channel is a sleeker, less expensive channel drain system that works well when used with pavers. The Z880 is a sturdier system designed for concrete installation. These two systems are so similar, yet they are worlds apart.

NDS Pro Series Channel Drains

NDS offers a line of channel drain systems called the “Pro Series”. These channels are injected, molded from polyvinyl chloride, and have a neutral slope (no slope). They come in a variety of widths (3”, 5”, 8” and 12”). According to NDS literature asterisk notes, this product is technology licensed from the Italian trench drain manufacturer First Corp.

This product line really has many options if you don’t want pre-sloped channels. From a manufacturing point of view, it makes sense.  NDS production facilities would need to stock a bunch of injection mold dies of varying depth in order to make pre-sloped channel systems  Injection mold dies are expensive!

With the Pro Series, NDS instead opted to make four channel widths to account for different flow situations.  Three of the widest products have two depths (shallow and deep channels). So, in effect, there are seven different channel options in the Pro Series.

Request pricing on the NDS Pro Series drainage system!

The photo above shows three of the four width options (I didn’t show the 12” wide option). The 3” and 5” wide channels come in 40 inch lengths (1 meter).  The 8” and 12” wide channels come in 20 inch lengths (1/2 meter).

Pro Series Channels Mean a Flexible Layout

A key feature of the Pro Series trench drain product line is the ability to cut the channels to any desired size. The channels come with a “double ridged” cut line every four inches (4”) along the length of the channel. This makes it possible to trim, for instance, 8 or 12 inches from the channel in order to custom fit the drain into a tight area.

Trim the channel using a simple hand saw. By making your cut in the slot formed by the double ridges, you can easily change the length of the drain while retaining an edge that allows all the standard hardware (end caps and other channels) to be attached . There is no patching of the channel in a custom length situation.

While you can cut a channel to a specific length, specialty channels are available for making 45 and 90 degree bends in the drain.  Side outlets are available in 5” and 8” wide channels.  Another notable feature is that every channel has a bottom knockout. This gives you flexibility when it comes time to place a bottom discharge. You can place a bottom outlet wherever you want.

Pro Series Grates: Know Your Options

Grating options are not extensive with this brand and vary by channel size. For instance, the 3” wide Pro Series channel only has a gray plastic grate suitable for pedestrian or light vehicle traffic. This may be adequate for home owners that are looking for a budget driveway drain.

The 5” wide Pro Series drain, however, has the most grating options. Plastic slotted grates (class B loading) are available in six (6) colors. Perforated plastic grating is available, but only in gray. A cast iron grate and a high impact resistant plastic slotted grate are also available in 5” width.

The 8” and 12” wide Pro Series products have fewer grating options. With the 8” wide channels, you have a choice of three plastic grates, one of which is perforated, and one slotted cast iron grate. The 12” wide channel only has a plastic slotted grate (light vehicle traffic) and a cast iron grate for heavy traffic. All grates, no matter the width, come in 20 inch lengths.

One thing I like about the Pro Series product line over other NDS brands (such as the Mini or Spee-D series) is that it offers more durability and life to your drain system because of the grate to channel width relationship. I feel it is important to have your grate wider than the channel of the trench. This is particularly important in plastic trench drain products. If the grate is wider than the channel, then the concrete that surrounds the trench will be giving added strength to the channel. Systems that don’t have this added support have to rely solely on the strength of the plastic channel. In this later case, if the ledge that supports the grate breaks, the load capabilities of the grate fail. More on this when I cover other NDS channel drains.

List prices of the NDS Pro Series cover a broad spectrum. The least expensive is, of course, the 3” wide system and prices go up as do the channel widths. Grates with higher load capabilities also come at a premium.

Plastic Trench Drain vs. Residential Trench Drain

Are most residential drainage projects solved by plastic trench drain?

It’s starting to look that way.

plastic trench drain options, NDS trench drains, residential trench drain systems, drainage solutions for homeowners

As society’s attention to stormwater runoff issues grows, so does our need to learn about water control products such as trench drains.  Concrete and fiberglass trench drains dominated the commercial market for years. These polymer concrete or fiberglass based drainage systems proved too costly, which leaves plastic as the alternative material for household drainage products. For many homeowners, plastic trench drain offers the best value – if they can find a drainage system right for their needs.

Go to the local landscape supply or home improvement store and you’ll only see a small sample of plastic drainage products. Maybe you’ll even find actual trench drain on the shelves. But ask yourself, “Is this what I want?” Most likely, this is not what you originally envisioned. Maybe you expected a bigger variety. Maybe you are uncertain of all the products available on the market or how to find them.
