i just made one for appartment dwelling. Only difference is mine attaches the pipe your shower head would attach to. I also included an extra T piece with a screw in plug so after i run it and get the crud out I can stop the water, added some detergent in the T, the start the water again and run some soapy water through which then turns to water to rinse it away. EVERYONE! with glass carboys should make this. I dropped my 6.5 glass carboy 2 inches and it scared the **** out of me (luckly it didnt break). Next day I built one for $20 and in 5 min with a drill and hack saw. I use to fill it with water, shake it, dump and repeat. This was back breaking, risky and time consuming. Using this it was 5 min, easy and much safer. Do yourself a favor and invest $10-20 on this.
