How to install Schluter®-KERDI-DRAIN-A Adaptor Kits

[@skeleman1963]

Great video! Especially on how to raise the substrate.

[@luigitosti7599]

Thank you Schluter Team for this video !

[@schlutersystems1]

Thank you for watching it!

[@swiatr]

Constructive criticisms of the video: 1) Focus on the KDA5 kit. It gets confusing when the KDA7 kit exceptions are included. 2) Include in the video that the adaptor flange is held in place by the orange rubber (?) gasket on the adaptor ring to form a water-tight seal with the existing drain. This might be a minor point, but it addresses my next comment. 3)NO bonding adhesive is used to glue the drain flange to the existing plumbing. 4) Why is Kerdi-Fix used on the adaptor ring? Is it an adhesive, a sealant or both? Thanks for a very good series of videos. The ARE very helpful.

[@schlutersystems1]

Hi there, thanks for your feedback, we will be sure to pass it along to our video team. As for your Kerdi-Fix question, the Kerdi-Fix is a single-component sealing and bonding compound that is applied to the underside of the adaptor ring mainly to seal it, however, it will also work together with the bolts to ensure it is well bonded. Hope this helps!

Great video Schluter team. Im wondering if the Kerdi collar is needed if you’re doing a mortar bed versus the prefabricated pan shown here? Seems like you’d just cover the mortar bed and drain with kerdi membrane?

[@schlutersystems1]

Hi David, Thanks for the feedback! And yes, you can just cover the mortar bed and drain flange with KERDI membrane. The KERDI collar is not needed over a mortar bed. Happy tiling!

[@dominicchirico1867]

Do you not use any adhesive to the end of the drain to connect to the drain under the floor? I am worried that this could cause leaks.

[@schlutersystems1]

The "drain under the floor" is never disconnected. The Adaptor flange is placed inside of the existing drain body that is already attached to the drainage pipe, so no need to be concerned about leaks!

[@crittersintheyard3993]

I find that I'm confused as to the different heights needed for different components. How to you know if you need an adapter kit or the regular kit

[@schlutersystems1]

Hi Mary, the adaptor kit is only needed if you have an existing clamping drain in the floor that you won't be removing. Otherwise, if there is not a drain in the floor currently, you would just use the regular KERDI-DRAIN. Please give our Customer Support team a call directly if you'd like to discuss your project in more detail. 800-472-4588 (US) or 800-667-8746 (Canada). Thanks!

[@benmcphail9334]

When using the KDA-5 how do you tile in the drain grate if you only use the height adjustment collar from the adapter kit

[@schlutersystems1]

Hi Ben! You may want to give our Product Support team a call directly to discuss this question in a bit more detail. From what I can gather from your question, it depends a bit on the installed drain elevation, it may be necessary to install KERDI-BOARD, tile backerboard, water-resistant gypsum backerboard, or similar prior to the tray to ensure the desired height is achieved. Install the tray as per the instructions on page 24 of our Handbook.

No PVC cement needed when installing these components? Thanks,

[@schlutersystems1]

Hi Bee, thanks for your question. PVC cement is not needed to install any of the components of the KERDI-DRAIN-A adaptor kit as this product is used with a previously installed clamping ring drain. Instead, KERDI-FIX (or similar adhesive) is used to install the bonding flange, and an acceptable thin-set mortar (i.e. Schluter SET, ALL-SET, FAST-SET, or unmodified thin-set mortar) can be used to install the remaining components, where necessary. Hope this helps!

[@benmcphail9334]

How do you tile in the grate for the kda 5 with the height adjustment collar?

[@schlutersystems1]

Hey Ben, sent you a message on your other comment. Thanks!

[@mitchmorgan8690]

Can any screws be used in the bonding flang

[@schlutersystems1]

Thank you for your question. The small, round holes in the outer edges of the KERDI-DRAIN flange are a result of the manufacturing process and are not meant to be used to screw the flange into place. Hope that helps!

[@beckyfrank9484]

What do I do if the adapter ring bolt pattern only aligns with 1 of the bolt holes to properly secure the adapter ring?

[@schlutersystems1]

Hi Becky - would you be able to call our Customer Support team to discuss your project in a bit more detail.. they can advise if drilling additional holes in the ring is possible, or suggest a solution depending on your specifics. 888-472-4588 Thanks!

[@ceeIoc]

Are there different grate styles available in the kits? I’ve only seen the classic one

[@schlutersystems1]

Hi Ceeloc, the Kerdi Drain flange with adapter can be purchased without a grate included, and the grates can then be purchased separately. Any grate except the tileable or the 6" are compatible. Hope this helps!

[@ceeIoc]

@@schlutersystems1 ok thank you!

[@schlutersystems1]

our pleasure!

[@hammerridecycling7630]

will this work with cast iron drain?

[@schlutersystems1]

Hi there! The KERDI-DRAIN can usually be connected by using a Fernco or different appropriate coupler. The Kerdi Adaptor kit usually fits. However, we recommend checking with a plumbing expert for the exact recommendation of how to make the connection in your particular application

[@woodydixon4996]

Will this adaptor work with pvc drains as well as abs since it doesn't have to be cemented to the riser?

[@schlutersystems1]

Hi there, yes this adapter works with PVC and ABS drains.

[@javiercarrillocarrillo4801]

If the drain is too low how can I adapt an extension to create elevation? (Mud pan install)

[@schlutersystems1]

Hi Javier, would you be able to give our Customer Service team a call to discuss your project in a bit more detail, and they can advise from there. 800-472-4588 (US) or 800-667-8746 (Canada). Thanks!

[@AmigosThe3]

How can we use this adapter kit with the Infinity Drains S-LTIF 65 Series

[@schlutersystems1]

Hi there! Due to the design of the KERDI-DRAIN-A Adaptor Kit the Infinity Drain cannot be installed with the adaptor kit. The Infinity Drain outlet won't fit properly into the adaptor ring of the KERDI-DRAIN-A Adaptor Kit. Hope this helps!

[@curt32807]

Is the Kerdi collar included in the drain kit?

[@schlutersystems1]

Hi Curt! Yes, it is.

[@TheIRL]

Is this compatible with Kerdi Linear drain? I have 5 showers to do, using this adapter kit, But 2 showers need linear drains

[@schlutersystems1]

Hi Kevin, the adaptor drain is not currently compatible with the KERDI-LINE drain. You can contact your local plumbing house for assistance with your connection, or if you would like to discuss with your local Schluter rep, please send through your zip/postal code, and we can send through the name and contact info. Thanks!

[@nicholaspizza3433]

What is the detail for when the center of the drain is located ~6" from the face of the wall, preventing use of both the KDA5 and KDA7 bonding flanges? Is there another way to tie the sheet waterproofing into the adaptor ring?

[@schlutersystems1]

Hi Nicholas, can you give our Product Support team a call to discuss your project in a bit more detail so they can advise? 800-472-4588 (US) or 800-667-8746 (Canada). Thanks!

[@nicholaspizza3433]

@@schlutersystems1 They were not able to provide a detail, any other suggestions?

[@schlutersystems1]

Hi Nicholas, I spoke to our technical team for you.... You can use the normal instructions for the KERDI-DRAIN-A installation, as the flange is only 11 13/16" wide, so 6" from the wall is enough room. Just slope your mortar bed toward the drain and cover everything in KERDI in accordance with the Schluter Shower Installation Handbook guidelines. Does this help?

[@billblendick9780]

Good product among others out there. The big problem with it is that it is obscenely expensive. This is in part due to their “pyramid structure distribution system”. The manufacture sells the products to distributors, who sell them to dealers, who sell them to trades, who then take another mark-up and do your job. The end result is priced through the roof. How many layers of markup can you put between the manufacture and the end user ?

[@darionwhite1849]

What type of polystyrene foam board is used? Or what is the required psi rating if you have to use this method to put down the shower tray.

[@schlutersystems1]

Hi there! Additional foam material used under the Schluter Shower Tray would need to be equal to or higher density than our tray, which is 80 psi. All layers must be fully embedded in thin-set mortar.

[@julian7426]

How do you install this grate?

[@schlutersystems1]

Here's a video on installing the complete Shower Kit. Grate installation starts at around the 14 minute mark. Hope this helps!

[@ronyrodas7058]

So much headache with Schluter drains

[@andym3277]

Seems like a lot of extra material and steps and money for the same outcome of traditional

[@aboston5740]

As stated "when removal of the clamping ring drain is not practical." The video does not show a concrete floor where it would not be practical. Wood floor with access to the floor joist well go for traditional.

Can this adapter be use with drypack instead of one of your trays?

[@schlutersystems1]

The adaptor kit can also be used in mortar bed applications

[@lamont22222]

@@schlutersystems1 Will the kerdi fix adhere to cast iron?

[@schlutersystems1]

Cast iron should be fine as long as it is clean and in good enough condition to bond to. :)
