DIY SURVIVAL CACHE
Creating a PVC Pipe Storage Solution
There are many reasons why you’d want to build a watertight storage container. Here we walk you through one method to make your own, small cache.
Your first trip should be to the hardware store to pick up some ABS or PVC pipe. We chose 4-inch-diameter ABS. It has a fair amount of space to store supplies, is easy to bury, and fits easily in hand or a bag. You’ll also need an endcap, test plug, and some PVC or ABS cement.
Black tube is ABS; white is PVC. For all intents and purposes for building a cache, you can’t go wrong with either. ABS is said to be a bit stronger and able to better withstand cold, but it’s really more a matter of using what’s available and large enough to store the contents you wish to cache. These pipe segments are the main components of your storage system. You can cut or have a length of pipe cut to your preferred size at the hardware store, but for this cache project, we focus on a 1-foot length of ABS pipe.
You can cut it yourself using a chop saw or handsaw. The taller your blade, the straighter the cut you’ll get. A hacksaw will tend to wander when you make the cut, so try using a regular handsaw for wood. Once you’ve cut your pipe, clean the edges of the pipe to ensure it seats well. Run a fine-toothed file or a piece of sandpaper over the outside and inside edge
to clean it up. This will get rid of any burrs from cutting it and allow you to get a better seal.
Next, test-fit your endcap onto the pipe and use tape to mark where it ends on the tube. This isn’t obligatory, but it ensures that you cover the entire area of overlap with adhesive. When taping something that you plan to remove, double over the end of the tape to make a small tab. This makes it much easier to pull off. Take the cap off and run the brush from your can of cement around the inside edges of the cap. Do the same for the outside surface above the tape on the pipe. Don’t worry about getting adhesive on the tape since you’ll pull it off later. Remove the tape and slide the cap on. Give the cap a quarter turn, as this will help the adhesive spread out.
With the bottom capped off, wait until the cement has dried and start placing items inside the tube. The first thing you should put in the tube is the desiccant pack. This will help control any moisture inside the pipe. If you can’t procure a desiccant, you can improvise with a small sock filled with cat litter.
This next part is optional, but we definitely recommend it. Place your items in a bag and wrap a loop of cord around them, which will make much easier to pull the items out of the tube later (think of how some tubes of survival matches are packaged). We also toss another desiccant pack in the bag. Never hurts to ensure your contents stay dry.
With your desired items stuffed in the tube, we need to seal it from the elements. This is where the test plug comes in. You may have seen other caches constructed using a screw-on PVC endcap. The issue with this method that you might need a wrench to open it. The test plug uses a butterfly nut that you can screw with your fingers to get a seal.
When you tighten the nut, it crushes the rubber seal, forcing it into the interior walls of the pipe. We recommend greasing up the metal parts heavily, though, to save you some grief later. For a bit of added security, take your last bag, toss it over the pipe, and then tape it to the pipe. This will keep any excess moisture from affecting the test plug and your metal parts. When you dig it up, you just need to tear through your bag and unscrew the top.
