TANKS, PUMPS and PRESSURE - 43 Topics Explained in 43 Minutes!

Water Delivery and Pressure Systems are complicated! There is a lot to know, like learning about pumps, storage tanks, pressure tanks, valves, flow, power usage, pump curves, pump labels and a bunch of other topics. I chose 43 of the most important topics and concepts to explain. To make sure I only explain the basics in a concise format I limited myself to 43 minutes for 43 topics!

A friends 240V pump recently died, no sound/motion whatsoever, verified 240V all the way to motor. For safety we wired it for 120V, planning to use a light-up tester, & powered it with an extension cord. To our surprise it started just fine, though I killed the power after ~1/2 second. I know the 120V-position puts the main windings in parallel, so now I'm wondering.... If one of the main-windings opens, is the good one still enough to let the motor spin?? Or can the voltage switch just go bad? We ordered a multimeter, so praying its the switch!

[@tigerseye73]

I had a submersible well pump that would not start. I pulled it from the well, and just for my own curiosity, I attempted to run it. The pump started fine. I tried the test several more times. AHAH! About every third or fourth attempt, it would not start. It was apparent that the centrifugal start switch inside the pump was at the end of its life span. Because our home needed water NOW, I simply went to the big box store and bought a new one. Problem solved. I don't believe the warranty these manufacturers give is worth the paper it's printed on. For one, they are usually pro-rated. Second, it costs money to ship a heavy pump, at the owners expense. Thirdly, who can wait weeks or months without water for the used rebuilt pump to come back, and at the owners expense again. My advise is, if the pressure switch is good, pump wiring is good, replace the pump and be done with the problem.

[@Carnivorous-Vegan]

@@tigerseye73 Unfortunately my theory was correct, 1 of the run-windings had burnt out. Apparently there's no such thing as re-winding a motor? So they just bought a new one. Time will tell if it was worth replacing just the motor, but they dont have much money. Lesson learned.. Pump protectors are good, cheap insurance against such things!

[@paengers]

@30:58 - 31:07 Im sorry i did not get this, why would the booster pump be inefficient in pumping water back to the pressure tank? Thanks!

[@NobodyNew02]

I think he just stuttered, pump is efficient in this scenario.

[@paengers]

@@NobodyNew02 oh i see, thanks!

[@erikvielman]

we use self priming pump to suck water out of the distribution lines gaining an advantage from the neighbors.

[@LarryElterman]

Haha, in most places it's illegal to suck water directly from the distribution system.

[@ForwardGuidance]

@@LarryElterman In the Philippines, the distribution line is pressure-weak so those that can afford it, attach a pump to pull water in, but like Erik said, you are pulling away from neighbors which is just the way it goes... kind of like tough luck for the neighbors. In places like the Philippines, water pressure is better at night after most people are sleeping, mid day one is lucky to get a few drops of water. Welcome to the 3rd world! People pull water from the distribution with a pump or stay up late in the night to get it and then store it in a tank to use during the day. I see high rise buildings go up in the Philippines and always wonder about the water. I regularly see a water truck parked outside of a condo building here - not sure if they are delivering tap water or to keep water in the pool. I guess there is ample supply of water here just bad delivery infrastructure that won't ever be fixed, because it is the norm here.... like the tolerated norms in Baltimore that Miami would never tolerate. Baltimore won't be fixed either.

[@LarryElterman]

@@ForwardGuidance First of all, don't get me wrong, i am not concerned with whether you or Erik does it legally or not, as long as it is not in my neighborhood! I was just letting him know it's illegal in case he didn't know. Now next point, It is perfectly easy to accomplish what you want to do legally if you so desire. You can get what you want and do it legally. There is no need to "suck water in". As you said, at night the system is usually better. So just let the town water go into a storage tank and fill it up at night. During the day, you get water from your own storage tank which you pressurize with a pump and pressure tank. What you are doing is crazy to be honest. No need for it! You are basically destroying the system for everyone else, and if you are caught I imagine you would probably get at least a hefty fine. Why do it the wrong way when it is so easy to do it the right way?

[@ForwardGuidance]

@@LarryElterman I'm speaking to how things go in the 3rd world out of necessity. People here also tap into a street light for electricity and in India (I've read) so they don't have electricity during the day. I know it is sometimes difficult to walk in another's shoes when you have a industrial world's basis so I will explain. People here have barely enough money for the pump let alone a storage tank and all the necessary items to automate water delivery. A day labor working on a construction crew here is lucky to make 12 dollars a day, a retail sales clerk in the grocery store makes 8 dollars a day. I was recently talking to a couple that works in a call center and have 3 kids, they make a combined income of 1200/month (one of the higher paid in the country). Your reply is very appropriate for someone living in the developed world with world class infrastructure, but it is completely off base for those living in the 3rd world. I don't know of a neighborhood in the US where the residents need to pull water - if they did, the gov't would surely add a bit more cash to the national debt or issue a bond to fix the problem. Maybe you missed it or glossed over it, but my comment started with "In the Philippines" so I was hoping that you would realize there's a case for pulling water when one doesn't live in areas that are infrastructure rich or where they can add to the national debt without huge financial risks.

hey Larry. whats your email. i have a question to ask about electronic pump controllers

[@alexjones976]

Good sir, you are incredible at explanations. This is the first video I watched from your channel and you did a fantastic job! Thank you for the time you spent making this video.

[@georgegordon1000]

Excellent job well done 😊

[@poiqweee]

Greetings, Larry. This by far and away was the most informative video on water pumps I have seen. Your explanation was simple, straightforward and easy to understand. It was exactly the information I was hoping to find. Diagrams are always useful. By chance are you an engineer? Thank you and be well, sir.

[@LarryElterman]

Thanks. I think it's one of my better videos, but so few views! Yes I was an engineer in my working life. Retired now.

[@elizabethreider225]

Thank you, Larry! This video was very informative- and the format was easy to digest. I am troubleshooting a pump (diaphragm tank) that recently started cycling on and off every few minutes. This pump is 15 meters higher than the well water tank. Next to the well water tank is a GRUNDFOS CM Booster PM2... It looks similar to the example at 37:55 in this video- with the addition of another pump connected to the diaphragm pressure tank.

[@ecopods1]

Hi Larry, can you use a expulsion tank to boost water pressure from a low pressure water mains supply. We need to supply 5 taps along a 400m pipe. Thanks craig

[@federicoaybar4652]

Excellent! Now I understand much more. Can you explain how does the Air Vol Control for the pressure tanks works? Air Vol Control

[@jcd4you]

Great video. I learn a lot from all your videos. Thanks.

[@derekorling7521]

I'm confident this will eventually get thousands of likes as time goes by. I'm only 8 minutes in and all the conversions will be a godsend as I try to dicipher how the heck I'm going to piece together my rain catchment/pond water system at an off-grid cabin. Thanks a million for your time and effort on this Larry. P.S. I found you because I was about to go the CSV route and decided to seek out alternative opinions... so glad I did! Take care.

[@LarryElterman]

You are very welcome. Thanks for your nice comment.

[@ibringthelastwords1358]

Hi sir Thanks for your wonderful video! Very informative specially for a newbie guy like me ☺️ I finished installing my pump but my concern is the pump cycle which have 2 minutes intervals for each cycles for 1.5 hours. So imagine it cycles 35+ times just to full the tank located in 3rd floor. I am planning to remove the pressure tank from the system and just running the pump from the source to storage tank. Is this ok? Is the pump over heat with that setup? Thanks in advanced 👍

[@LarryElterman]

Ok, you gave me a little more information to work with, but i am still confused, but at least now i can ask questions. Your description does not really make sense as written. What kind of tank is it on the third floor? A pressure tank or a storage tank? A pump should not cycle to fill a pressure tank, a pump cycles when a pressure tank is used up, this is why you will have to provide a far more detailed description if you want me to help you. For example, you say two minute interval. What does that mean? you mean the pump goes on for two minutes and then off for two minutes? Why are you going for 1.5 hours? who is using the water? See in order to help you I need to fully visuallize what you have. Right now i am not even close to visualizing what is going on. Do you mean you have a pressure tank below and a storage tank above? and your water from the pressure tank is going into the storage tank? If that is the case your system is set up very wrong :) How does your system know when the storage tank on the third floor is full. I will help you if i can properly visualize what you have and what you are trying to do.

[@rudymagarin6292]

very good work thanks

[@diorismoreno]

Great video!

[@Ramfiju]

Great video, lots of info. Can you improve the water pressure in a house plumbing if you add a pressure tank on a gravity feed system?

[@LarryElterman]

You mean you currently have a gravity feed system and you want to improve pressure? Or do you mean you want to change to a gravity feed system to increase pressure?

[@petefaulan2286]
