Well pump testing involves measuring the recovery rate by drawing down the water level and calculating how much water the well produces per minute, while water quality assessment requires visual inspection for clarity and sediment to determine if the well water is suitable for household use; in this case, a 525-foot well produced 4.2 gallons per minute with crystal clear water, indicating a successful well installation.

Over 500ft Deep, How Much Water did it Make? Is it Clean Water? Lets find out!Added:
All right, folks. Well, welcome back.
This is a job that we did. Uh, it was a 52 minute long video, and we drilled this well. What did we drill it? Five, 600 feet, something like that. 525 ft.
And we ran into some dirty water. So, if you haven't seen that video, go back and watch it. It's pretty good video. So, the audio is kind of iffy, but um we had 5 gallons a minute and we had to line out the upper area. So, there was a vein at 86 and 98 and we took those out of the equation.
Now, there was still another vein at around 135 and we could hear that in that video and it's dumping in water. So, we don't know how much the well actually makes now. So, we're back here today to do a pump test. So, I've got my generator right there. I'm walk over here. I'll show you the pump that we're using.
This is the Grunfus SQ290.
This is a 10gon a minute pump with a one horsepower motor on it. It's probably one of I would say this is my second best seller. My number one best seller on the website is the SQ250.
That's a 1 horsepower 15 gallon a minute pump which I would say the majority of households in America that are on wellwater have a 10 gallon a minute pump in it. And if you want a little bit more volume then you can bump up to a 12 or a 15 gallon a minute pump. So they're rolling this pipe out. We're going to put the pump in at 300 ft.
And that's pretty much the maximum depth for the SQ290 because I think it can provide 5 gallons a minute at if the water level was drawn all the way down to the pump cuz it's trying to overcome that much distance.
So, we're going to go ahead hook up the wires, get it all done. I've got multiple multiple well pump installation videos on the channel, so I'm not going to be covering the topic of putting the pump together. This is just strictly for the pump test. So, once we get this all in, we'll put it in the well, turn the generator on, pump it for a couple hours, and we'll uh try to calculate the recovery rate and show it to you all on screen. Okay, we got to put a 4-in well seal on it. So, on the bumper, you got the 4-in well seal. open that box up >> and we'll put that on it. That's just going to be for temporary to where our uh our boom box will work through the vent.
>> It'll hit the water pretty quick.
Water's like 20 ft from the surface.
>> Now, since this is a 3-in Grumpus pump, it's kind of like a smart pump. And since we're running it off of a generator, I've heard of and I've had issues with running Grumpus on generators in the past. And the answer to why that is is don't hook up the ground wire. I don't even know why hooking up the ground wire has an effect on it, but it seems to. Uh I think two of my subscribers have tried running Grumpus in the past, and both of them fixed it by not hooking up the ground. I don't know if it has some sort of like, you know, voltage feedback or something like that from the generator or lack of a grounding rod. I'm not really sure, but you just simply hook up the two power wires and turn it on and it should work. Now, I had one of y'all ask me, how do you keep the 4-in pipe from falling down the well when you remove the clamp? So, this void right here, so the pocket between the 4-in pipe and the 6-in pipe, you have to pump concrete into this section here, and it sets up and it locks it in permanently. That's what it does. But you have to test the well first before you put in concrete to make sure one, the water is nice and clean, and two, the well makes plenty of water. So, that's what we're here. We're here to see the clarity and the quality of the water and to determine how much gallons per minute. Then we will stick a pipe down this all the way to the bottom at 110 ft and we will pump liquid cement in the well from the bottom up and we'll pump say 300 300 lb of concrete which is three bags and then we let that set up for 24 hours and we come back and we do it again. If you put too much the concrete gets hot too much weight of the concrete it'll actually heat up the 4-in pipe and collapse it. We don't want that either. So liners are something that takes quite a bit of time and effort to get right.
Soft start so it doesn't jerk the generator.
There she goes.
That looks beautiful.
I'm happy already.
So, this is going to be my measuring bucket. I've got five gallons right here, four gallons right here, so on and so forth. So, I'll use this in conjunction with the timer on my cell phone to figure out, you know, gallons per minute, more or less.
Right now, what I really wanted to do is just catch a bunch of water and see if there's any sediment in it. But the clarity of that looks gorgeous.
So that top number 81.4, we'll click it again.
That's the water level depth. I'm going to bring it all the way to 110 ft and then shut off the generator.
I'm going to do one test up shallow and then another test down deep.
Seven. All right, that's close.
All right, let's go check that.
All right, 108. All right, I'm going to do a timer and some math real quick. All right. So, I just shut the generator off at 108 ft.
By the time I got to do my test, it was already at 104.6.
And now the depth was at 100.0.
Now, it's at 98.8.
So, it's coming up relatively fast. It's coming up 4 feet in every 60 seconds.
Now, that's only inside of 4 in casing.
It's not inside 6 in. So the typical math on that for 6 in would be a gallon and a half of water for every foot of rise. I'm going to guesstimate and I'll have to do a little research. I would say for every foot of rise inside 4 in is probably one gallon. So just that really quick initial like preliminary test. I'm going to say four gallons a minute. But now that I got a baseline, I'm going to go ahead and send it on down and see what we can truly get down deep. Because the 4-in pipe and the 6-in pipe terminate at 110 ft, I was afraid that my box wouldn't register correctly if the echo because this is this works off echo location. And I was worried the echo would get a a weird effect of the 4 in and the 6 in transition down deep. So that's why I did a preliminary test up shallow. And in theory, the well should make more water as you draw the level down because it has to overcome less head pressure of pushing the column of water up. So the more you drain the the water level down, the faster in theory that it should recover. So let's see if this well still makes 5 gallons a minute because that's what I assumed. So all right, I've been talking for a minute and 40 seconds. It was at 98 ft.
should be at 90 or Yeah. Okay. 93. Not bad. So 93. That came up uh 8 76 54.
That came up 5T in a minute and 30 seconds. So 5 gallons in a minute and 30 seconds. So not bad.
All right, let's keep pumping.
All right, back at it. Let's see where she's at right now.
93.7.
I just want to pull the bucket away.
It's a little It's got a little turbidity in it.
It's not super It's clear for probably the first 3 in, but then it looks a little discolored. But this bucket was not 100% clean.
Good god, that water's cold.
I'm excited to see what it makes.
So, right now I've got the water level drawn down to 180 ft. It's only been I don't know about 15 minutes, but it's pretty good. The sensor is working even though the transition of the 4 and 6 in, which I was kind of concerned that maybe it wouldn't. So, I think I'll be able to draw it all the way down to 300 feet.
The pump is supposed to supply 5 gallons a minute at 300 ft. So, we're going to see if it'll balance itself out or actually cut itself off. I've never seen a Grumpus pump shut itself off on a dry run scenario. So, we're going to see here if it'll shut itself off on a dry run, which I doubt it will. I think it'll just sit there and balance itself out because it's not going to run completely dry. If the well still makes four gallons a minute, which I'm assuming it does, it should balance out at four gallons a minute. We'll see. All right, we're 30 minutes into the pump test and I just noticed it got dirty.
So, that kind of factors in with the way we blew the well out. You remember when we blew the well out, we got 80% clean, clear water and then it got dirty right at the end. So, this may just be what was down there and we got to get it out.
So, my hope is towards the end it'll run slower but clean. Cuz if the liner doesn't clean the water up, there's no need for the liner.
You can see the turbidity in it. Let's see if it settles out. Let's just move this over.
We'll give that time to settle and we'll see what it looks like. Let's check the water level.
247.
Not bad.
Hit it again. 248. So, she's still going down. Want to get it all the way to 300.
All right. We've been pump testing it for about an hour and for maybe the last 10 minutes it's been cycling on and off.
That's the Grumpus safety shut off. I can hear it very very gently in the uh in the um generator. But what it's doing, it's just shutting itself off. It waits a little bit, then it turns itself back on. Really, really awesome feature of the Grumpus pump. So, let's go ahead and check the water level.
We're at 300.8.
Right on the money.
Perfect.
All right. So, it says 301. Now, let's go ahead turn the generator off.
All right. We're going to do a test here. I'm going to give it five minutes.
And in five minutes, we're going to see how much the well recovers from exactly 301 ft starting now.
All right, getting close to 5 minutes.
Let's go ahead and check it.
All right.
All right, it made 14 ft of water in 5 minutes. All right, so it's uh 14 feet, gallon and a half per foot. That's 21 gallons in 5 minutes. So it made 4.2 gallons per minute. Originally, when I drilled it, I said it made five, and I assumed that the dirty water vein was one gallon a minute. So, my assumption was I was going to cut off a gallon a minute, which was going to leave me with four. Based on that test right there, and the test at the beginning of the video at 110 to 105 ft, both of them, we're right at four gallons a minute roughly. So, we're going to do one more test. We're going to run it dry again and count over a minute. We'll do it all live here. And we're going to see how many times I can fill the bucket up while it's cycling on and off because that's draining the well completely empty. And we're going to fill the bucket up and see how much we can catch in 60 seconds. Let's do it now. I'm pretty satisfied with 4 gallons a minute. And now the fact that we've drained the well completely dry, like all the way down to the pump, the well is replenishing itself only with the water that's coming out of the aquifer.
Right? So, you can tell the clarity of the water is so much better now. Like crystal clear.
I like that.
All right. It just ran out of water.
It's cycling now a little bit differently. Earlier was cycling on and off. Now, it's giving me a steady stream.
Soon as it pits out, I'm going to start catching it in the bucket. And then that's when we're going to start our timer.
I'm just using my record timer on my camera. I'll be able to feel the pump inter. There it goes. I could hear the generator kick on.
Generator goes under a load.
All right, that started at the 28 second mark.
So, we'll run it all the way to the minute and 28 second mark and see what we catch.
I'm at 50 seconds now. So, that's 20.
All right. So, right now marks 30 seconds and I got a gallon or I got two and a half in the bucket.
Looking to get to a minute and 28. I'm at a minute and 10. Let's go.
I think we're going to be close to uh what the boom box test was. The boom box test was 4.2 gallons per minute and we're coming in. We do five 4 3 2 1 and that's it. Okay. So, like the bucket test is identical to the boom box test.
The boom box test said that it made 4.2 gallons per minute and we are right there. That's the 4 gallon a minute mark. You can kind of see, you know, the bucket's a little unlevel, but the well makes great water.
Nice and clean. You can see to the bottom of the bucket.
Not bad. Remember that's fresh. The well was drilled literally two days ago. So, it hasn't given much time to settle. We just pumped it all out. So, this is probably the worst that it's going to get.
I don't think a need for any big filtration. The water looks nice and clean and clear. No red iron, no brown dirt, no nothing like that. Really good.
Very happy with it. All right.
301 again.
Awesome sauce.
All done, guys.
We're just going to leave the pump in it. Later on, what we're going to do here, I know people are going to be like, "Oh, where you going to leave it up like that?" No. So, the pump is going to stay in it for now because it's super heavy. You can't pull a pump out of a dry well, right? Well, I'm going to eventually have to pull the pump out because I got to cut that 4-in casing down inside of the 6-in casing. So, I'll cut it like, you know, four or five inches below the surface of of the 6-in pipe. But, I've got to cement the liner in first. So, we're going to have to do that over a couple day period of time.
Once the cement has had time to set up, then I'll come here, pull the pump out, take the clamp off, cut the pipe down, and then install the pump again. When we do that will be the same day that we trench in a water line and electric line to this house. But we're going to we're going to pause on the whole pump system for right now. They've got some grading and some stuff that they want to get done here. So the pump system isn't a uh isn't a drastic rush right now, but um I did want to know how much water the well made. I stamped it five and it makes 4.2. So very happy with that.
All right. Well, there you have it. This entire series, me drilling the well, putting in the liner and the pump test was all at the customer's request. He wanted to see the video. He's been subscribed to the channel for a while and uh he wanted me to make a video out of it. So, since he wasn't here, I decided I can show absolutely everything from start to finish. Even if the well did make a lot of water, which I was kind of concerned, I was going to be happy if it made anything over two, makes 4.2. So, it's enough to run absolutely any household. You can water the lawn as much as he wants. I don't think you could waste more than 4 gallons a minute out of a garden hose under pressure and all that cuz that pump once you put it under say 50 PSI of head pressure trying to fill a bladder tank, it's going to actually reduce the amount that is able to pump out because it's trying to build pressure. So that pump is supposed to supply five gallons a minute at 300 feet and still satisfy the pressure switch. So it's almost perfect. It's almost perfect. That that that pump is perfect for that well.
Honestly, I tagged it as a 3/4 cuz that's what I was originally going to put in it, but we put a 1 horsepower in it because we needed to put a 3-in pump inside the 4-in casing. So, you don't ever want to put a 4-in pump inside 4inch casing because it could melt to it. It's going to be hard to pull out, stuff like that. So, that's what Grumpus pumps are for. 3-in pumps are for 4in wells. You can put them in 6in wells, too. No problem. But best on the market, in my opinion. All right, I'm gonna end it here. Thank you'all for watching. Four gallons a minute. Great day. Peace.
