Today, I wanted to send out a reminder for our DIY Clay Tools Video Contest, sponsored by Digital Ceramic Technologies. If you missed my first announcement of the contest, go here to learn more about it and the amazing prize our sponsor is providing!

 

And what better way to inspire you to get to work on your videos than to share an article about a great homemade tool. In this post, potter Charan Sachar explains the cool design of his easy-to-make and super-effective sink trap. Have a look, and then get out your video camera and start filming for the DIY Clay Tools contest! – Jennifer Harnetty, editor.

Working with clay can sure be messy, and throwing your mess down the drain is just not an option. Having worked in several studios during the last five years, I learned a lot about what works and doesn’t work in a studio. When I finally set up my own studio in our new home, planning every tiny detail was exciting and I wanted to tackle the sink-trap problem. I set out to create something that improved on previous designs, which all had shortcomings. There were three problems that I wanted to solve. First, connecting pipes to round buckets is annoying, and they are prone to leaking after maintenance. Second, opaque traps make it difficult to determine when the trap needs cleaning. Finally, under-sink traps are difficult and unpleasant to clean.

 

The first thing was to attach pipes to a square bucket rather than a round one (fig. 1). The outer large bucket is a sturdy 10-gallon square translucent storage container. It needs to be strong enough to take the weight of water and clay, and have at least one side as flat as possible to attach a pipe to the sewer drain.

If you think your container is not strong enough, use two containers for added strength. On the inside sits another square bucket (a cat litter bucket works well for this purpose). This bucket serves as the first filter. Drill three rows of holes in the top 4 inches on three sides of this bucket. Do not make holes on the side that faces the sewer outlet because water pouring from the holes will agitate the sediment close to the drain.

The height of your trap depends on the height of the sink outlet and the waste pipe. Because my sewer drain is high, I had to raise both my sink and the trap (fig. 2). You may not have to do this. The sink legs are fastened to the blocks so they cannot be kicked out. Hooking up the trap is easy. Use washers and silicone to make a watertight seal for the drain (fig. 3). Locate the smaller square bucket at the end farthest from the drain. Even if there is a lot of clay water flowing out from the inner bucket it will still flow on the sides, which are farther away from the main outlet, giving enough time for the clay to settle before the water goes out.

To solve the inconvenience of cleaning the trap, I located the entire trap to the side of the sink rather than right below it (fig. 4). When the trap is located below the sink, it is hard reach, remove and reattach the fittings. By directing the sink trap to the side, there is no need to remove any fittings, just pop up the lid, rotate it around, and the sink trap can be cleaned easily. No loose connections, no mess! I installed this sink trap over a year ago and it has worked great.

 

When the settled clay level reaches a certain point, you know it is time to clean. I clean it once a year and it takes 15 minutes without any problems. Also because the bucket is transparent, you can actually see if your clay trap is working. It makes me feel very comfortable when I see clear water seeping out the outlet.
