Great Site esshup- My area looks to have .13 inch evaporation a day so thats nice to see.

Arond- the pressure tank would allow me to use the water for other purposes as well like irrigating. But I would rather not wear down the pump either and My driller says there is less risk of me accidently tearing up the pump as well with a valve when a tank is attached???

I never wanted to irrigate the land much anyway so I may just stick with no pressure.
