Well, if you are not seeing all the incredible awesomeness built into this little plastic beauty, let me point it out to you. First of all, for those of you not really familiar with plumbing, the J-Trap serves two purposes in the sink plumbing: 1) It prevents gasses from coming up into the sink from the sewer or septic by continually holding a small amount of water which helps block the path of sewer gasses back into your living space, and 2) the shape prevents larger objects or heavier objects from exiting via the pipe, thus providing a natural catch-space for jewelry, sand, and other objects which otherwise might be lost or damage the plumbing if allowed to travel in the system further.
Traditionally, pipes are not made of materials that are see-thru, so if you develop a clog or think that Great Aunt Suzie's ring fell down the drain, you would have to disassemble the entire trap to see what the clog is or if the object of your desire was lucky enough to settle there. This J-Trap has a convenient gasketed "trap" door that allows you to easy access objects or clogs without having to be a plumber and with a minimum of muss and fuss. Here is a demo of how it works:
Now let me share what excited me so much about this item with regards to its application in a tiny home. This J-Trap will allow me to plumb for gray water drainage outside of the tiny home OR allow me to open the J-Trap and drain the fluids into a 5 gallon bucket (for example while traveling to the new location where I plan to park my tiny home. I will have a potable water tank and a 12 volt pump, so it is still possible to cook, wash, and do dishes even if not hooked up to my gray water system.
If you would like more information about this product, you may wish to go to Amazon, Ebay, or to search for "Clear J Trap." Unfortunately www.clearjtrap.com, which is stamped on the side of the pipe, is no longer an active website. I hope that does not mean the company has folded. That would be a shame because this is an awesome product!
