Hi William; Nice video. I too live with gravity water.
One thing I have learned over 40 years , is about "line loss" or friction. You mentioned a thousand + yards down to the house with the blue pipe?
That's too far. I assure you more water will make the house if you do the following. Every 100 yards or so you need to switch back to a larger size pipe for APX. 50' - 100' then back to the blue pipe.
This eliminate friction. A 1/2" pipe that is long
enough literally will flow nothing, no matter how much is entering... 1" does the same just goes farther.
Your red pipe looked relatively short and might be just fine... but adding a stretch of 2" pvc in the middle won't hurt.
Keep up the good work and keep us posted with photo's!
