Increase GPM from old point drive well
Our cottage is fed from a 2" point drive well with a 1/2 HP jet pump.
This was there when we bought the place about 15 years ago, and we have not touched it since.
Currently its outputting about 3 GPM.
I am hoping to increase that to around 10 GPM if possible.
Any ideas on how to do this? I am considering running a new 2" point drive well, and installing a higher HP jet pump. Seems like the obvious option.
My concern is that the issue is the water availability in the ground rather than the current jet pump or the point driven well. But I don't know enough about these systems to really have a valid opinion!
Can someone with some experience chime in and point me in the right direction?

2 gpm is not livable, our well produces 24gpm and we get along fine.
Unless your willing to have a larger and deeper well drilled not much your going to do to improve the situation.

Thanks, yeah I'm hoping to increase the GPM.
Is that a reasonable with a new 2" point drive?
I don't know how deep the current one is, but its probably safe to say its at least slightly clogged by now since its likely around 20 years old.

Welcome to the forums.
Shallow point wells are not typically high yield wells.
Your yield depends mostly on what's in the ground.
A neighbor or well company could give you better estimates than we could.

Thanks.
The neighbors have typical cased wells. But we are down in a valley, the lowest property around, which is why I think we've been able to use the shallow well.
I wasn't sure if 10 GPM was reasonable to expect from a point well or not.

An alternative to drilling another well is to convert to a two stage well system. You install a cistern (non-pressurized tank) of a few hundred gallons as the new first stage. The existing pump can take all night if needed to fill the cistern. You add a second pump, a shallow well style will do, to move water from the cistern into the house system with pressure tank, and establish the 60/40 or so PSI.

THanks, yeah thats a good idea.
I think tomorrow I'll spend the time to look into just drilling a 4" cased well and adding a submersible pump.
