The box says 21 PSI on the outside. There were other versions, including the one I linked above but it was only 8 PSI.
I also just got my mcmaster plastic spray ball, this thing is tiny! Off to the hardware store to put together my fittings.
I have that same pump!
Mine works great! 25gpm I think it calculated out to. I got it for 30 bucks with a coupon.
Tip for any doing this, use the smallest tube you can like 1/2" pvc so the water can drain out fastest. Also drill small holes not large. I fould 1/8th was too large and pumped too much water into the bottle and it pools at bottom.
use less holes as well.
4-5 on top then a row of small holes around where the fermenting line is.
The thing has some force and it like a pressure washer. I don't have to leave mine on for more than 5-10 min and all clean using PBW.
oxi clean foams too much.
dishwasher soap even worked for me before I bought the PBW cleaner.
my total build cost was about 40$ and I would recommend this project to anyone!
I still need to adapt mine to have the keg hose hookups.(cut the PVC and put them in someday)
Here are the 2 wands I made so far. I am going to make a third 1 with smaller holes and less of them like I said.
little video of mine in action..(old video with the 1st tube I made out of 3/4" PVC. I don't have a new video of other one running. it is the same thing pretty much. lol) you can hear the pressure!
washing my keg fermentor.
