How many Gallons Per Minute Do You Need?


(Thankfully, this is NOT the cabin we put the offer in on.)

My husband and I are looking for a cabin.  In fact, our offer was accepted on a cabin.  While we toured said cabin, the realtor told us the well produced 13 GPM.  That seemed adequate for a place we'd only be using here and there.  However, we found out from the well report, it only produces 7 GPM.

When you have a family get-together, there can be 10 people in the house--and lots of showers, baths, teeth-brushing, dishes, and laundry.  Also, we can have up to 4 horses on this property, so I'm hoping to bring a couple of horses with me when we go there.  (Fill up their waterers.)

That said, the cabin is au natural, so doesn't need any lawn watering.  Just the household stuff.

Here's another caveat, we'd like to use it as vacation rental--a Bed and Barn--right on the lake.  People could come up, use the place, ride their horses, and fish or water ski, or whatever they want to do on a lake.

Is 7 GPM enough?  I need your help!

  1. I have no idea about the water, but I can't wait to hear more about your cabin! And see pics! How exciting! I hope turns out that 7 is enough.

    1. It's a beautiful cabin. I hope it works out, too. From what I hear, 7 GPM is adequate, but you wouldn't want less than 5 unless you have a reservoir. We need to have it retested and see if it still gets 7 GPM. The well report they gave us is 13 years old.

  3. Seven gallons per minute from the well should be fine. Seven gallons per minute from the pump might not be enough.

    The "well rate" is how fast the ground water leaks into the well housing before it is pumped to the surface. The well may hold hundreds of gallons that has leaked in non-stop, even over night when you are not using water.

    The "pump rate" is how fast the water goes to the faucets. A hose bib can easily run 7 gallons/minute by itself.

    They are probably talking "well rate", so you should be fine.

    1. Thank you! That was very informative. I assume they're talking about well rate, too. There was an "air test" performed that yielded 7 gpm, but we called the well company who did it today, and they said that is not the actual test for GPM. They did the test and it was yielding 12 GPM in 2003. We have a well inspector coming out Friday morning to do an up-to-date test. I am pretty sure, though, that 7 GPM would be adequate. 12 GPM, even better. Fingers crossed! At our primary home, we get 28 GPM.

  4. We have a very low producing well -- I want to say it is in the neighborhood of 3 gpm. But, it is a steady well (very important) and we have a holding tank. The previous owners did not have a holding tank and they could not run the dishwasher, the washing machine and take a shower at the same time. With the holding tank, we have never had a problem. There are usually just the two of us, plus the animals and my garden. We have had up to 8 people in the house at the same time and we had no issues with water. We do not irrigate our pastures -- just my garden and orchard (16 trees).

    1. Wow, at 3 GPM, they couldn't do all three things? Makes me think 7 GPM could be a little tricky without a holding tank, too. Maybe not. I'm really hoping the well is still getting the 12 GPM they told us it tested at in 2003. We've had a lot of water this year, and I've heard the aquifers have replenished themselves. Water is the most important commodity--you forget how important until faced with a lack of it. We have a well inspector coming out Friday, so I'll update this with the information he gives us.

    2. Having the well inspected is key. We learned so much that way.

    3. Sounds like your well and this one are very similar. However, they do not having a holding tank. Also, they went 180' to start, then 520' when that wasn't enough, and they still only get the 3-4 gpm on this wet year. If it runs dry, I don't know where they'll go to get more. So, it's a risk we're not going to take.

  5. Sounds like you've got some good info from everyone. Friday you'll find out from the tester what's what and can go from there. Hopefully the well will produce more than you need :) the cabin sounds wonderful! Can't wait to hear more about it.

    1. Friday will be interesting--well and house inspection. We've only seen the cabin once, so it will be nice to get a better look at it and take some measurements while they're doing the inspections. We're finding it out that it's hard to get a 2nd home insured, too. Apparently, there are more claims made on 2nd homes due to robberies & natural disasters, since most 2nd homes are in the woods or on the water. Makes sense.

  6. I think you should be ok. You could always put in a cistern (holding tank) if you have room for it. How exciting that you are getting a cabin! What lake is it on?

    1. It's on Lake Spokane, or Long Lake, in Nine Mile Falls. The lake is about 20 miles long and the people around the lake are really nice. There isn't any commercial industry on the lake--no restaurants, gasoline, etc. Almost all the homes are primary residences. There are restaurants and gasoline in the town, though, just not that you can access by boat.

  7. Turns out, they only get 3-4 GPM and the well is 520'. It's a risk we're not willing to take, so we're walking away.
