In my free time, I invent stuff. Most of the stuff I invent relates to the plumbing trade (duh). I have over 30 inventions on my computer. Here is one thing I invented. I have found it to be very helpful in the field (especially on commercial work).
You simply take a 4" pump ball. I build an adapter where I can attach my 4" pumpball directly on the end of a piece of 1/2" pex pipe. Using this setup, I can shove that pump ball deep into the pipe directly through the open pipe that I use for my 10' head test. I pump up the ball through a fitting on the end of the 1/2" pex pipe.
I can shove that pumpball into the building drain 20, 30, 40 feet...whatever is required. I don't have to use it much. But this thing saves lots and lots of work and prevents lots and lots of water from spilling all over the ground where I'm working.
I'm just trying to get some feedback on this invention. I had to have some of the fittings custom-made at a local metal shop and wasn't sure if there was enough interest out there to place an order for a short run of 1000. Opinions?
