Well it turns out what they had was a pressure gauge. No one in this area seems to have a vacumm gauge except for the digital ones which are beyond my price range. So i ordered one off amazon. Technically a compound gauge(pressure/vacumm), so it comes in and its only a pressure gauge. So now it is being sent back because they shipped the wrong one. Strange week!
I have been wondering around some of the local hardware stores and picking up some very useful information reguarding sand and gravel aquifer we sit on and ways the locals put pipe down(much easier than my process). I explained where i was in depths and soil composition. He told me I really have two options, pull up to 20 feet(where the first white sand was), or go deeper till i hit another white sand area. He explained this is water bearing area usually and provides much cleaner water. This area is heavy in sulpher and iron.
Well I decided to come up, cause going down is basically starting over. So now my pump throws out 20 GPM. Pump still makes cavitation sounds till i adjust the the ball valve to almost closed and reduces output to 16 GPM. Only thing is that the water is a good orange/stinky mess. Clears up a little after running for a bit, but i don't want to stain my property.
So have decided to use the information I learned from the locals and go deeper where the water was much cleaner. They use a 2" pipe with a bit/plug combo, then an inline screen(which is pvc wire wrapped design) and a bailer(sand sucker). When you get to the depth you want you pull the bailer out, drop in this wood plug and rest the bailer on top of it overnight. The wood plug seals the bottom and keeps the sand out. now you are ready to start pumping!
Ill let ya know what happens when I go at it again. I forgot to note that it turns out that we are currently having a servere drought!
