We have a new well and I just installed the pump equipment. The well is 330' deep artesian and the overflow is 2.5 GPM. When capped it builds up 6.5 PSI pressure. The submersible 7 GPM (correction - 10 GPM stated earlier) pump is hanging at 100' and the pitless adapter is installed at 5' below ground. The well drillers report indicates 25 GPM yield at 320' drawdown for 2 hours.
All is running fine BUT I'm not sure everything is the way it should be.
- In the top cap, I installed a vacuum release valve as shown in this picture: https://i.imgur.com/H6501Zu.jpg
- If I open a couple of hydrants at the same time the water level in the well casing sinks rapidly. When the hydrants are closed the water level rises again (without the top cap).
- When I have the top cap in place and open the hydrants I can hear the vacuum valve sucking air as the water level sinks.
- The water level is sinking in the casing running the 10 GPM pump. If the well yield is 25 GPM and the overflow is 2.5 GPM should the level go down if I take out 10 GPM?
- The well driller indicated 25 GPM yield at 320'. Is there any reason why he checked the capacity that deep?
- If I continue to draw water and the vacuum valve continue to bring in air, is it possible that I will fill the entire casing down to the pump with air and ruin the pump?
- If I remove the vacuum valve at the top and the cap is sealed, will there be a vacuum in the casing as the pump runs and how will that affect the pump and performance?
Any input appreciated.
