In an effort to improve cleaning effectiveness and safety I have thrown together what has turned out to be a simple and cost effective solution. Cleaning HTs can be troublesome and dangerous with trapped pockets of air and hard to reach places with deposited layers of "filth" (also known as "soil" in the cleaning industry). Complete removal of cleaning chemicals was not easy either. I could see that a way to flush the HT from the bottom, at any angle, was going to be necessary. My solution is two #2 drilled rubber plugs (you can get these without the hole for a cleaning stopper) connected by a length of Silcon tubing. Really the Silcon is overkill in this application but I had extra laying around and I like its properties. Not only is this safe because its all rubber and tubing, but since the rubber stopper will "blow out" under too much pressure, this should help protect sensitive trees from accidental overpressure when opening the water supply. I started with 1 foot of tubing and then doubled it. No glue was used, just pulled the tubing through the stopper, worked it back and forth to smooth it out, then pulled it back until it was flush with the end. Not bad for about $5. I was going to shoot video but have no extra hands atm, so pics it is.
