These pieces of plywood, are grossly undersized, and the weakest part of these trusses. and the bottom cord might be a little too high. The lower the bottom cord, the stronger, pick you strength. In an area like east Texas, the wind would tear these apart. In a area of heavy snow load, there could be spreading.

Doesn’t the lack of sediment in the last filter tested mean it isn’t working . It isn’t trapping anything.

Thank you. This helps me.

Where did you buy that 3 inch poly tubing?

I've got a bunch of leftover T-track, do you think I could replace the included bottom board with it and it would make things a bit more stable in the center?

Next time seal the joints so the pressure doesn't escape. The original pump isn't debunked. However, YOUR artistic interpretation IS totally debunked.. As for the 'lost cause'.., I won't be following you.

I did learn a few good things from the video. Thank you for making it. BUT, please please please for the love of your feet... PLEASE wear "not sandals"

I dont understand why spinning when using water? As it sound in video it hardly will make 20m3 before worn out, and not being effective when back flush and cleaning. I guess there was something wrong and should not spin during normal use, only during back-flush. Am I right or wrong?

Any chance you could setup a pump with a stand pipe in the system so we (I) can have a better idea what you're talking about??

Nicely done demo and clear display and explanation of the results, well done!

I really like this product eval/demo being a real project, it would be great to see more of that in future videos.

Well done practical test. With the 6 ft. head pressure what was the minimum delivery height for the pump to keep running? Does this suggest a fixed ratio between drive head pressure and minimum delivery lift to maintain backpressure?

How many hours did it take you to build this? Thanks

This was exactly what I was looking for! When I bought this switch I was under the assumption that this is how it would operate, before learning more and that what I want is a DPDT on off on selector switch. Thank you so much!

Very good tips on installing roof alone. I'm an amateur builder as well, always tend to over build. I use (8) 4x4's on footers that hold everything from floor plates and joists to the roof plates. Seems like simply framing on a platform is weak.

I just bought this and only using for my 8000 btu ac but it runs only 4 to 5 hrs with full tank of gas. Any suggestions how can i make this run longer?

Could you use poly pipe for some of the fbegging amount then convert to PVC for closer to the ram pump? What’s the minimum number of feet of PVC pipe?

Thats not even enough to power my PC. Waterpower without highly specialized turbines leads to kinda disappointing small gain.

This is a great video. I've been trying to figure out how to get my work/lab/studio space to be adaptable without looking like a horder with ADHD lives there and putting things on wheels means reconfiguring is a lot more flexible.

If your already generating a/c why not use that directly for normal use? This seems unnecessarily complex, and your losing some power with each change. Would a motor/generator be more efficient for the a/c - d/c conversion?

Wouldn’t steel give a higher yield still

That wire definitely needs to go up on some poles to keep it from being a tripping hazard.

how bout securing the pipe with stakes, etc.

👍

This would be better if you had pipe sizes, lengths, and elevations.

Looks like it wastes half the water coming out of valve. Any reason why you dont just use a solar pump?

Crazy timing. Today I installed my ram pump that I bought from you. I used poly because that is what I had on hand. I was wondering about the jump and using PVC. I have a 2" supply pipe for 275' then a 3/4" drive pipe for 75'. Think I need a stand pipe or does the 2" supply line essentially act as one? I just came inside while I wait for the water to come up the delivery pipe which is 800ft long.

Thanks for the info, I'd suspect that it would be better to use some metal pipe then because PVC isn't meant to deal with "water hammer" full time, it probably will develop cracks as PVS is rigid as you said, it's also kinda fragile too. This video was helpful though, thank you.

I'm curious if the ID of both pipes are the same?

Hi Seth, I would like to see a comparison between poly, pvc and galvanised steel with respect to flow rate and maximum pressure ? Nice video as always! thank you.

I wonder how much gain you would gain on the poly pipe if the poly pipe were buried in gravel or buried with rocks on top of it so it wasn't able to move

Length of drive pipe is supposed to be about three to seven times the head height for maximum efficiency. This means the vibration loss is minimized compared to a longer run of drive pipe. To accomplish this an intermediate stand pipe can be used as you stated and has the effect of arresting the vibration. Also, from experience, the pvc pipe will eventually develop cracks and fail since it is designed for rigidity but not the kind of constant water hammer that a ram pump has. This I know from experience. Usually the cracks develop lengthwise and can be difficult to diagnose as a reason for pump efficiency losses. The only solution that maintains the high output over many years is to use (stainless) steel drive pipe.

How rough are these to drive over in a vehicle?

Great demo. I'm curious to see if you weigh down the poly pipe (or PVC for that matter) with a brick or other means to keep the pipe form bouncing. How much more water would be delivered up hill in 60 seconds?

Good to know, as I will now not replace my 125' of 1" PVC drive pipe with poly pipe. We thought the poly pipe would be less noticeable in the creek, but I can't afford to lose the elevation loss in the supply pipe. Great test!

Good experience to pass ❤

Wonder how much a whole system installed would cost …

Great video showing exactly what I needed to see. Thank you!

That larger filter requires a minimum gpm flow to function properly according to spec.

starting the pump should be a lot easier to start if u hold the waste valve open a couple seconds. maybe try it out sometime.

Hi Seth, love the video! I have a physical disability which would make it very difficult to build a system like this (and join pipes together etc) but I love the physics of it all! Thanks very much :)

What height is that, how many liters come out per hour

I know it is very old video, just come a cross. I am mechanical engineer so lets clear this out the way. Under water , the volume of the water in bath tab creates a pressure, So, this is why you loose pressure on the gauge. Think like this ( I do dive ) , when you dive deeper you go, water pressure per sqm or inch by volume in ocean or sea this much higher obviously. So, this why your pressure is gone down due the water amount in the bath tab. On the other hand if you keep it close to surface and it will keep similar amount of pressure or close to same without water test. Second thing, you can create multiple ramp pump and connect to another one in line that will creat much higher pressure and volume. Also, amount of the water in source equal to weight and pressure, say 1 m3 of water and 1 meter high and in conical shape bucket or design, it will put all the water pressure in to single point 1 bar pressure will be achieved then ramp pump will increase the amount and you will get constant and higher pressure. I have a different design which I can not disclosure, but you can actually not only create higher pressure but continous water flow and create stand alone power house. I have already done some small prototype and still need a little more testing and adjustments, once completed actually you can use similar system to make power that I would say around 5 KW per hour , at lease this is my aim, but my set up already making 200 watts and continous. As the system gets bigger then some issues arised, So I need to solve them before I can say it is completed. Anyway, I just wanted to make an input. Thanks.

Thank you! You were right, the screws behind the stand are tricky, but the vid was great and my dryer works again!

I got one when they first dropped. Their laser update software wont let me update the firmware. Fire alarm goes off constantly. Customer service tries to help (slow email responses only) but no resolution. Pretty bummed because this is a good machine. When it starts to cut or engrave, its great for about 5 minutes. Then the alarm goes off without a single flare up.

That is like a premiere edition compared to H.F.'s. Theirs is 10 dollars more and not as nice. The tubing on theirs is a lot t6hinner as well. One door and no windows. The H.F. ones doesn't have the push buttons on their tubing frame also so some people put self tapping screws in them. Great job!!

Dude 300 hundo pounds I would have a Thick steel wall protecting that thing from whatever , also Brother you want to see how much your system can handle just start buying space heaters even small ones take a ton a juice start plugging them in and when your system blows up that's how much you know it can handle

I thought EG4 made this battery? Is it really made by lux power and EG4 and BigBattery rebrand it?

I can’t seem to get mine past the 13.2 v and charge controller reads 100% I’ve had it for one day tho

Hello, how is this inverter working to this day is it any good? have you encounter any problems with it, thanks!
