everything else seems the same, not sure why mine is less then yours...
still , i can see how much of a time saver this is going to be.
Do you have any issues with pumping PBW or anything through the pump?
Glad to hear it's working! Twelve inches should be plenty of flow. The mechanism here isn't blasting gunk off with physical pressure, but rather eroding it with a heavy flow of water. With enough time, I've found this is as or more effective than the jet washers.
In any case, there are a number of things that could effect the height of the stream coming out of the nozzles. If your copper diameter is slightly larger, for example, you'll have equivalent flow but less height. Alternately, if you're getting constriction from your fittings anywhere along the way, this could be restricting your net flow.
I've had no problem with PBW, though I get a fair bit of foaming with StarSan. It's never been a problem for me, but if you start overflowing your sink you could use SaniClean or another non-foaming sanitizer. I can't say for certain that the chemicals don't shorten the life of the pump. I've used mine thirty times or so now and it's still going strong. I also take comfort in the fact that these pumps are designed to pump filthy water out of flooded basements.
Keep us posted on how it's working for you!
