John, I would love to see a follow up on how and why you select a pump based on a pond or pondless design. For instance is it just based on your water in motion calculations/TDH or a formula for cycling and filtering a pond as well. What factors determine solids handling vs non Fish, trees, amount of water in a pond etc...

Great videos thank you. I do have question. If there is a wetland (8x10ft) with that is below the level of the pump but there is a water column on top how do you calculate the head pressure? (I currently have a 3-PL on it but would like to change it.

@richardbroszeit8523 6 месяцев назад

For those who want the maths, look up Poissuille's law. The rate of flow is proportional to the 4th power of the radius, meaning that doubling the radius (or diameter) will give 2^4=16 times the flow.

@mattoriental Год назад

Great informative video John, and the info about the larger pipe diameter invaluable - thanks. I have a question too: If my pump is in the bottom of the negative edge reservoir and is pumping water up (say 4') and then across at ground level (say 17') and then down into my centipede module (say 3') how do I calculate the differential elevation? Matt

@KoiAddiction Год назад

I go from “operating level” in the reservoirup to highest elevation level for lift height. Then use all piping involved for your run and typically add 10 feet of pipe for every hard 90 that I use.

@RodJetton 3 года назад

Do you submersible pumps on rec ponds folks will swim in? Love the videos you do. Very very educational!

@KoiAddiction 3 года назад

Yes external pumps for recreational swim ponds are a must in my opinion. That’s what we are using on the pond I am currently building at home.

@chiahuei 3 года назад

Great video, you've really made it simple for people thinking about ponds! Speaking of lowering friction and hence pump head, why do people use such long stretches of flex pipes when this is really terrible for friction losses? A straight pipe will get you 10x less friction. A flex pipe will never achieve laminar flow, and turbulence and all the slight curves will add to friction losses. What are your thoughts on this?

@KoiAddiction 3 года назад

For most applications it is about ease of installation. I have used both types but typically it is just easier. So much time saved in construction doesn’t make financial sense to hard-pipe smaller jobs. Lots of elbows can off-set the friction loss on flex-pipe. Most of the time the mistake I see is too small of diameter on pipe eating up flow rate. I will use a combination of flex and sch. 40 on my feature, depending on the run and how crazy it gets.

@johnrugg4511 3 года назад

Hi John, Thank you for the valuable explanation. Can one replace the PVC pipes for flexible pipe, eliminating the 90% bends ?

@KoiAddiction 3 года назад

Yeppers

@justinjordan1428 3 года назад

Great video, quick question. If you go to a 3” pipe to get better flow rate does it matter that it has to be reduced for the pump fitting and biofalls ?

@KoiAddiction 3 года назад

The reduction will increase friction loss so the shorter the better on the length of the smaller pipes and be sure not to exceed the flow rates on your biological filters- it causes issues!

@williamweaver1658 3 года назад

Hi, big fan here. I have watched this several times to make sure I am understanding and at last I am in a position to be able to use this info to help me get the right pump so thanks. One question though, if the pump only has a 2" outlet will you still get the 60% increase in output by increasing the pipe to 3"?

@KoiAddiction 3 года назад

Yes, though 60% was the difference in my example-you will have to run the total dynamic head pump curve with your pump to see what the difference is in your case!

@alexezpeleta3345 2 года назад

Helo Jonh G. thanks for all your videos, they really help. In one of them you mention not to use a submersible pump in a recreation pond. Ist´s just for safety or is any other reason. Thanks from Puerto Escondido, México

@KoiAddiction 2 года назад

It is a safety thing. No other reason. Hiding externals is more work BUT in my experience most of them are affordable and repairable in comparison to some submersible pumps so there are some other benefits.

@johnhildebrand8740 4 года назад

John - Great info. Your examples are both submersible pumps. I will be using external pumps. If my external pump has a 2” port in & out do I get the same boost by using 3” flex both on my extraction from the neg edge reservoir and out to my wetland filter? Or should I draw water out with 2” and push to my wetland filter with 3”. Help please! :) Do I just “neck up My fittings at the pump housing?

@KoiAddiction 4 года назад

You need to run the pump curves using the formulas to be sure you are still in the pumps sweet zone. As long as you are not exceeding the pumps capacity on the draw end (length, head, etc.), you will get more flow with bigger plumbing. Just make sure it doesnt decrease head pressure too low for the pump! Did that answer the question?

@johnhildebrand8740 4 года назад

Yes and thank you! I will pay close attention to the calculations and TDH.

Hi John what size pump should I use for my wetland filter. The wetland filter is 7' x 12' the pond is 10,300 gallons I have pumps running the waterfall already and skimmer. The wetland filter will be done this spring. The feed into the wetland filter will be coming from the intake bay which is about 20 feet away. Elevation which is the head will be about 2 feet at wetland filter. Which pump do you recommend for this wetland filter GPH and what size hose. If I have to use two pumps one for the intake bay and one for just the wetland filter I could do that also. Thanks

@KoiAddiction 3 года назад

I would love to see the wetland design. Typical flow in our designs is 1500 - 2000 gallons per centipede assuming you have followed similar design practices. Be sure you use actual flow rate on your pump using the pump curve and flow losses based on total dynamic head.

@KoiAddiction 2 года назад

@KoiAddiction 3 года назад

I love the Aquasurge pumps for efficiency BUT they need to be properly installed in a skimmer in a low head scenario. Be sure to use the total dynamic head calculator to determine actual flow with each pump you are considering to find the perfect choice!

Pit a 12” drain basin next to liner for over-flow or use a simple dry stream style overflow next to the intake at a low area🤘🏻😎both is even better!

@adampinales2945 3 года назад

Does GPH change if you split a 3'' pipe into two 1.5'' pipes? If so....based on friction loss, I would assume that you wouldn't want to split it any closer to the pump than say 5x the diameter of the pipe.........but I could be completely wrong. Any thoughts?

@KoiAddiction 3 года назад

Yea,I keep the main line at a large diameter as long as possible and try not to put more jets than the flow permits- so if I have a 10k flow I will use a max of 10 jets. If you are concerned use larger jets and then you can reduce down again if you need more push. I’m no engineer- I work with pump company and a diagram on larger systems!

@stanleydouglas7174 3 года назад

Hi , I have a swimming pond in NY and I don't like the idea of having the pump in the water for posable electrical shock and we freeze up here so I would be removing the pump every winter. Is there a dry transfer style pump you would recommend for 18' lift 1500 gph?

Hey jhon thanks for your information got a 3 inch line running into the pond for my three jets would I come off the 3 inch line or T off into a 1 inch or 2 inch line for my jets thanks again

@KoiAddiction 3 года назад

I do 3” in to carry high flow-when split do 2” lines from tee “splitting” the flow, then reduce to 1” only @ the jets for a short run. You get more flow that way!

@zackjames5487 3 года назад

Hey John quick question using an adjustable Flow SLD 4 to 7 GPH running the 3 inch line how many jets could I possibly put in and still have a good flow Ponds kind of large and about 5 1/2 foot deep thanks again

Is it ok to “T” into the pipe from my vault or do I need two different pumps? If I can T into the pipe can I just buy a ball Valve on the pipe to the spillway to regulate the water? Just wondering if there is going to be enough water volume for both

@AndrewJames92 2 года назад

Hi guys. Another question for ya. I am wanting to move a lot of water (315 gallons p/min). The TDH is 3 meters. (4 inch pipe, open-ended system - so from a lower pond up to a waterfall). I have seem some installers will put multiple submersibles in parallel. So in this case, I could use 8 submersible pond pumps (all high flow, low head), or I could use one high power external pool pump to do the job. The disadvantage of the external pump is noise really. I am concerned about putting 8 pumps into on 4 inch pipe though. Any thoughts on this?

@KoiAddiction 2 года назад

I would do the external probably and figure a solution for the noise. Final decisions would be based on Pond purpose, pump cost, electrical costs, etc. Weigh the pros and cons. I have never pushed multiple pumps through the same pipe….that’s interesting. Seems like it might create a competition…I would love to hear more about that and why it is a good idea or not.

@KoiAddiction 2 года назад

Youll have to plug your numbers into a Total Dynamic Head Calculator (google one) and then match the head pressure to the pump curve (in catalog & on box) to see what your actual flow will be after head pressure and then decide if its heavy enough for you. Ill shoot a video on this next week!

@KoiAddiction Год назад

There is so much more that goes into the planning of the proper pump. I would have to know lift run size of pipe requirements of your filter, type of intake, etc. in order to be able to properly. Answer your question. Typically I try to use multiple pumps because pump redundancy is a safety net, in case one burns out which always happens eventually. I’d be happy to talk with you about it, but I would definitely need more information :-)

@mazinalkhakani7483 3 года назад

Hello... the pump is how many liters per hour used in the waterfall

@KoiAddiction 3 года назад

I do GPH. Flow should be 1500-3000 GPH per foot of waterfall width (as a rule). You can always do more BUT that is a rule of thumb!

@zackjames5487 3 года назад

Hey John one question on this topic if I go with a 3 inch flex PVC but there’s only a 2 inch coming out of the pump once I use the 2 inch into 3 inch adapter will I still gain the extra flow rate or will the 2 inch section cancel it out thanks for your info

@KoiAddiction 3 года назад

No you will def gain the advantage. Keep the 2” as short as possible👍

@Mark-ff9en 3 года назад

The reason being that a 3 inch works better than a 2 inch pipe is the friction of the water against the inside of the pipe. The bigger the pipe the less water touching the pipe that is why you can start with a 2 inch pipe then increase to 3 inch pipe and get more flow out of your lift.

@KoiAddiction 3 года назад

Yes, what Mark says! 2 things affecting your flow inside the pipe are velocity and friction loss. Think of people walking in a hallway- the skinnier the hallway the more difficult it is to pass. As you add more people (higher flow) the passage becomes more difficult. As the hallway gets bigger (larger pipe) the passage becomes easier 😎

@KoiAddiction Год назад

I think 6’ wide x 3/4” thick is about 15,000 GPH. SO that would be ABOUT 40,000 GPH flow to get about 2” thick @ 6’ wide. That won’t go through a 3” pipe. At low-velocity you are going to be pushing 10.000 GPH ish in a 3” pipe.
