I decided to replant the yard cus the wife wants it dark green front and back. The well I use to have had so much iron in it, it turned the grass orange, wrong color..lol. Anyway the first one Pat and I washed down we went down around 70 foot but there was so much clay in that area I decided to move it towards the house. Pat and I had a hard time around 20 foot. I decided to buy a gas powered mud pump and pump out the sand,clay. This bad boy pulled about a ton of sand and clay. We had a mess. We still weren't getting where I need to get. I decided to use the mud pump to wash it down instead of pumping it out. That was the ticket.We got down to 50 foot in no time.I want to get down to 100 foot. 180 would even be better. My neighbor say his is only down 13 foot and he has just a hair bit of iron in it. In this area you can hit water between 12 and 22 foot. In my case I haven't be able to hit it.Anyway washing this down was kinda of cool. I brought two fifty gallon containers, filled them with water and used the same water to wash it down instead of using household water which by the way has no where near the pressure that the mud pump has. This guy at this site has been very helpful >> http://www.drillyourownwell.com/index.htm One of the biggest problem we have run into is cave in at around 45 foot. He suggested to use clumping cat litter to prevent this. I ran out of time last weekend so this Sunday we will try that. You can get some drilling clay also to prevent cave in. I told Pat, look I don't wanna end up spending 10,000 for this well project...lol I would have hired it out but there was noway to get a drilling truck in the back yard unless I take down my fence and my neighbors fence and that would be a close fit. Most drilling companies around here want anywhere from 2 to 4 grand and don't promise anything.
