# Single (1) Drain into 1 ReefMat 1200
{% hint style="info" %}
#### Basic connection of the RM1200 to the sump.
* You can use the corrugated black pipe that is included with the RM1200 and the adapters that Redsea has included. But be aware that you need to use a 1.5" to 1" PVC adapter for this to work as RedSea only include a 1" PVC connection for the stock plumbing.
{% endhint %}
#### For higher flow we recommend using 1.5" PVC Pipe plumbed directly into the ReefMat1200 with our included 1.5" to RM adapter.
Pre Installation:
1. Find the included 1.5" to RM adapter that we have included with your sump (It may be white or black).
2. Connect the adapter to the input of the RM1200 as shown in See figure A.1 below.
3. Attach legs to ReefMat
4. #### Build the PVC Manifold (See FIGURE A.2 Below)
Here is a list of the parts needed all PVC is 1.5" Sch40:
* [ ] 1 x 7" PVC in Length
* [ ] 1.5" DWV 90-degree Street Elbow Fitting ([Found Here at HomeDepot](https://www.homedepot.com/p/1-1-2-in-PVC-DWV-90-degree-Street-Elbow-Fitting-PVC003020800HD/203393437))
5. Connect Manifold to center 1.5" Bulkhead on the sump.
6. Slide the RM1200 with RM adapter into the 90-degree Street Elbow fitting. No Glue is needed, or recommended, just pressure fit. See Figure A.3
