We have been making a skating rink for the kids for a few years now. It started a few years ago two tarps in size then four.
Last year I upgraded the hose from the regular garden hose fed from 1/2” pipe to a 1.25” pipe that comes right off the well tee.
We can now flood a massive amount of area in one tenth the amount of time. Below are pictures from the third day of making the rink, it’s now an inch thick flooded directly on top of the grass and is skateable. It still needs one more thin flood to make it smoother, but it’s looking good.
