The linear drain I've been looking for

[Houston Remodeler]

Saw this in this month's NTCA newsletter.

Compotite makes the drain I had been thinking about for years. I have a call into the area rep (Dallas) awaiting response.

I'm eager to see one in person

What part of this are you finding significantly different from other such drains, Paul?

It all sounded pretty similar to other such drains as I read their requirements and could see it working well enough (having also not seen one in person), but when I got to the bottom of the page and saw this part I began to worry:

Using Installation Methods 1 & 2 Together For Added Security.

Hey Paul, I know you like MAPEI products so I'll also point out that we have a great linear drain system. I'm not sure what features you're looking for that other drains don't have but ours is pretty well thought out. Here is some additional information:

Thanks for the info, this is the link to the installation video of the Shower Perfect system

In the past my favorite has been the Laticrete drain for its sheer simplicity of just 2 pieces. The big drawback is the lack of adjustability to the grate.

CX, the injection moulded abs construction which makes the base part much cheaper than the welded and shot blast stainless steel bases or the machined plastic.

What does this drain do that a Noble linear drain doesn't?

[Houston Remodeler]

Far less parts to worry about, but they all do the same thing in the end.

What I like best about the KerdiLine drain is the frame for the grate. You set it with mortar while you are setting the tile, enabling adjustment and you can make your own weepholes.

Where exactly would you make weepholes on a Kerdiline Drain, and why would you want to? Where is the water going to "weep" to?

[Ron]

This is in comparison to an ACO drain. On that one and some others there is a frame attached to the channel body. When you set the drain in mortar it has to be at just the right height and placement for the tile. The frame attached to it which is like a wall around the grate prevents moisture that gets under the tile, between the tile and surface membrane, from getting into the drain... so you'll get grout discolouration around the grate.

With the KerdiLine drain, you set the channel first, flush with the substrate. Then, you can set the separate frame in mortar and adjust the height and a bit of lateral placement. When the frame is set in mortar you can leave some voids here and there so if there is moisture getting in the grout and under the tile it can weep into the drain. Much like a square Kerdi Drain which also has a frame for the grate set in mortar although on those I have never made the weepholes.

Ron: I have not heard of anyone setting the Kerdi Line grate assembly in mortar. It's meant to be removable and stays loose. That way the hair catcher can be cleaned out once in a while. I still don't get what you mean by weep holes with either square or linear kerdi drains.

Mind you I have only ever used the tileable grate assembly, maybe the metal one is different.

[Ron]

The grate assembly is in two pieces; the grate and the adjustable frame. That's what I like about Schluter's linear drain. The frame is set in mortar. You can install it before, during or after the tile to get it at just the right height... can even put a small tilt on it if it's against the back wall.
