is this gpm figure low?

We moved into a place with 400' well. The company that drilled and installed it says it is rated at 1.0gpm. Is this on the low end?

I don't know beans about wells, but it sounds low to me.

Might be why we have such a large accumulator.....

make/model # of pump might get some answers.
I am no well guy at all - but i would think that 3-5 gpm would more inline with the minimum out put.
how big is your storage tank?

The output of the well has nothing to do with the gpm of the pump.

I have talked to other well drillers from across the country, and 1 to 3 gpm from a well is not out of the question.

In my part of the world that would be a dry hole, but in other parts, that is common place.
So, your well may very well only make 1 gpm.

Thanks. The lady at well company pulled their ticket and read everything off to me. It was drilled in 2000. She told me it was rated at 1gpm. Seems low.

But, I notice in our yellow pages you can do refracing of wells to "increase water". Refracing is expensive, and it doesn't say how much you can increase water.

Better of living with it the way it is. It does fine in our house. Runs showers well, dishwasher, etc. Good flow in sinks.

Just curious.

No well person here...but if it works for you..leave it alone. I don't know how 1 gpm would run anything for very long...unless you have a real big storage tank.

A shower uses about 1 gpm all by itself.

Normal city water at common pressures runs between 3-5 gpm AFAIK.

This is a local knowledge thing as waterwelldude said.

I have a question: Have you talked to your neighbors about this? I am promising myself that I won't go off on my "How insulated we have become" rant.

Barber shops, Beauty Parlors, Hardware Stores, local libraries, among others are goldmines of local knowledge not just for this, but for many other things you may wonder about in your new locale.

Don't enclave yourself in front of your computer. Get out there and talk to people.

One other thing, educate yourself about your basic infrastructure before there is trouble.

Look at the water system until you know exactly how it works. Read the sticky. Pay particular attention to my post about how a proper cycle is supposed to look and hear. Figure out what kind of septic system you have and learn how it works. Do you know where your electricity comes from? Where the transformers and substation is that feeds your house?

Knowing these things BEFORE there is trouble, can save you a lot of money and costly errors.

Believe it or not, I have had to get up in the middle of the night and show the power company man where the blown main circuit breakers were so that he could restore power. I got tired of listening to his truck driving around and around while he looked for them.

Well. A mini-rant.
