What’s so difficult for people to understand? Sailboats with foils travel 3X wind speed every day. This is just a sail car.

My vent was noisy during sleeping hours so i was using my technical knowledge to reduce the speed and the noise. I was sure i can make it quiet by using just a simple color coded resistor but you gave me a better method to use a light bulb 💡as resistor and it sounds nice. thank you sir 👏.

wow

The old style is still cost efficient, supposedly long lasting if maintained.

Water tanks with bladders or diaphragms should be banned. Ours was a diaphragm tank (from a very reputable and well known company) and apparently the materials used for the bladders and diaphragms slowly degrade over time and leach out toxic materials into the water. They claimed the materials used are "food grade" and "safe" but the laboratory tests proved that is completely untrue. If you're going to buy a tank, ONLY get the old style stainless steel pressure tanks. They are the safest.

Very good explanation. I was thinking of using a dimmer, but I'm glad that you advise against it. Won't waste my money on a dimmer. Now I just need to find myself a transformer.

Thank you Larry you are a good teacher

The last solution presented has some issues. For one, having the pump powered by two separate switches, on two different outlets, with conductors bonded together could become a hazard. The flow detector switch will need to be sized properly and pull from the same circuit as the pressure switch, possibly using pigtails. Another option is to use isolated switches to independently close a normally open relay. The relay will control the pump. The second issue is that the flow detector switch will keep the pump running with any flow, say 1 GPM. If your pump is a 10 GPM pump, it will outrun the demand and build destructive pressure. You will need to make sure your pump cannot develop pressures higher than your system components can handle. Most pressure tanks have a max psig rating of 100. Some go as high as 150. Commercial options can go much higher. Typically, tank manufactures require a pressure relief valve somewhat less than the tank's rated pressure, such as 75PSI. If your pump builds pressure beyond this, then the relief valve opens. Let's also not forget, that typical pumps have a minimum runtime. This may be one minute. Your pressure tank needs to be sized to allow your pump to run for its minimum runtime. This allows the motor to cool. Short cycling will burn up the motor.

Very interesting. I will try it

What if I use a voltage regulator that we use for ceiling fans in stead of bulbs

I skipped the dryer and put the damp underwear on the board for a day. Once it is air dry, I am done.

So helpful thank you for doing this video, tried many brands and recently bought expensive underwear and they are so uncomfortably tight on the band. Thanks again, jo, UK.

Cavitation in the pump head! If a pump water flow is restricted, such as with a CSV, it creates pressure in the head of the pump which will cause cavitation and diminish the life of the pump head.

Dear sir, thank you so much! I'll go try this method now, because I've been dealing with this problem for year+ today

When electricity was much cheaper, I used to heat my house using 2 3kw radiators wired in series. This would do 2 things:- 1 being the heat output would be half of one radiator, each radiator would now consume only 750 watts a total of half the original amount of the original single radiator. 2nd is that the life span of each radiator is pretty much limitless as they don't get anywhere near as hot as they were designed for. The benefits were quite staggering because not only half of the electricity is being consumed but the heat output, even though halved was spread around and heated the house much more effectively! I used to wire up Christmas lights with a few extra bulbs in series to make them last for years, I have a set still working that is over 20 years old now :)

I just thought about a better way to protect the pump and save electricity; the new refrigerators now use inverter technology upon which the speed of the pump is controlled when there is lower demand. IMO, a CSV after the tank (not on the tank junction) will provide constant flow and pressure, while the pump can be reduced in speed when there is a high level water in a big tank. It will need water level meters in various heights of the tank and maybe also a feedback control from the CSV will tell the pump to speed up or slow down. It is getting more electronic and complicated in this method, but in electronics, feedback makes a system very efficient. The problem with mechanical machines is that they are prone to wear and tear and difficult to employ feedback mechanisms.

Very useful info. Much thanks.

*my noise is squeaky noise not what i was looking for but stayed to listen so you get* 👍 *i'm just gonna throw WD-40 but if it shorts out problem solved* *glad i stayed to see your McGyver technique*

A hero of our times

Thanks

Your missing something. And I get your shairing what you know but... My galvenized vertical tank has a port/bung on its side where there is a pressure guage and a plunger float thingie. Its operation is to bleed off air pressure after each draw. Thus avoiding the waterlogging issues. Also Its outlet to the house is about 3" above the inlet from the well. For me it acts to collect or trap setement. I have noticed hard water stains are showing up much quicker over the past year or so and i believe its because the 3" setement trap is full. Ill have to spend the afternoon clearing that out. Its prob taken 15years to build up. Edit: I should add, when my well turns on I hear air bubbles being pushed into the tank for a few seconds. I believe when the well shuts off, the water in the supply line drains back into the well. Maybe bc its below the frost line.

A clear thinking, logical and creative mind behind this. Very helpful and I will be using this, thank you for posting. Occurs it could also be used to relax sock ankle elastic which is usually too tight

A well company recommend I get an in-well pressure tank due to space/freezing concerns (crawlspace, no basement, etc.) I can find almost no info about in-well tanks online. I did find something stating they need a CSV or VFD due to the low capacity, which is how I got here. Do you have any intel on in-well tanks?

Well done sir. Thanks so much for your effort.

Funny seeing this. Earlier today found out some super cheapo Chinese batteries leaked out in my kitchen timer. Corroded connections. Had to clean it up, and luckily still works. At least it counted time the same as my other timer for the 30 minute test. I usually throw the cheapo Chinese batteries away, and even the more expensive (also Chinese made) brand name batteries now leak sooo often, can't use in anything you don't want to get ruined. The major brands have leak so much more often now, so much so that have to use lithium batteries in my good flashlights and other stuff.

Ya... my dad got VERY messed up from the injections. Day after bad leg pain. Day after dropped and couldn't recover, had to be ambulanced in. Happened again later. Then, and don't ask me why, or how it got passed me, but he actually got the second dose. In theory he should have been asked about negative reactions and disallowed. Immediately after, dropping and ambulances happened several times in just a couple weeks. Malfunctioning heart. They put in a pace maker. Dropped again. They figured the pace maker (2 leads) was either malfunctioning, or leads weren't placed quite right. Second surgery, same model. No change. They then had to put in yet another, but the oversized model, with 3 leads. Went from no heart troubles, to needing the oversized model of pace maker, in just a few months. But leg pain the day after indicates it was attacking his nervous system, which makes sense, since the spike proteins contained in those injections are neurotoxins....

You did a great job, and I appreciate your efforts. Learned a lot, and needed to. Thanks

Thanks. But my problem is other way around. I have had a loose running boxer and want to tight it's elastic. kindly suggest some method to get it tight.

great information cheers!

My brand new diaphragm lasted about 6 months. I won't buy product from a company with that type of quality control. That's how I handle warranties.

I was ready to just pitch it and ho back to the store and have them explain but nobody at the store who only wirks fir 5$ an hour ciuldnt figure it out. So i looked on line and foubd you. With trial and patience i got it. The knife i got gas 2 little springs in under the metal slider so i pulled them to make them longer and it gave more pressure for pushback. Then reassembled all of it according per your example and bingo it worked! Eyerka! Trump 2025 all my problens goes away! Go trump!!!❤😂🎉 thanks man!

Thanks! I tried to do it myself but bungled the job.

#9- a system WITHOUT a CSV will also drop to 40lbs before the pump kicks is- Cmon Larry

If somebody really wants to understand the CSV And what the true implications are you need to on A data recorder and log use use of the motor And how much draw it is taking over a 24 hour period with and without a CSV. That’s the only true comparison

outstanding video

Just buy a variable resistor and use your vary the speed. Can’t sleep with the light bulbs just as the noise Did.

This explains why I can cut straight with a circular saw! Thanks

My pump pumps water at the well head at 25 gallons per minute with no tank with a 240 hook up. And t fills my 35 gallon bladder tank in about 1.5 minutes. So my question is how does this thing work? There's no wires so it can't slow the pump down. My pump bypass pressure is 80 lbs so it can't be pumping through the bypass valve at the pump if the gauge says 50 lbs. And if I install one, and it's only supplying a demand of 1.5 gallons per minute, wouldn't that take about 15 minutes to fill my pressure tank back up? And if the pump is backing up through the 80 lbs pressure bypass, wouldn't that put an extreme amount of pressure on the motor? None of this makes sense.

I'd like to know what happens to the rest of the water being pumped. My pump has an 80 lbs bypass. This whole system sounds shady.

VFD’s are very expensive! CSV valves work great, I hav had multiple in use for over 15 years. I am sorry, your information is very wrong.

Thank YOU!!!

Conclusion: Old style SS tank is still the best. But its up to you to try new style 😂

For a true comparison, you would have to add all of these scenarios together. Nobody that turns on their tap 20 times using 1 gallon of water that’s ridiculous. Probably half of those maybe 1 gallon. So what you need to do is add all your scenarios together and average it out to see if the advantage of constant pressure outweighs whatever excess energy or pump cycling is. In the end I think you were probably even.

You are incorrect in your assessment as your simulation of a restricted motor does not translate into a motor that is attached to an impeller that moves water. The motor is only receiving the resistance from the impellers. If you shut the flow of water, then no work is being done. Thus the motor will spin faster and do less work, which will equate to less power consumption. As an example, it’s the exact same scenario as when you put your hand over the end of the vacuum and the motor speeds up. The vacuum is not pulling a vacuum that’s the motor is doing less work, which means less electricity being used.

Thanks a lot Larry! I couldn't figure it out myself.you help me a big time!

Thanks for sharing.

I don't know if this will help you Professor but with respect to string tension if the tension is low the strings will have a trampoline effect means the ball will have more pace (faster). Now when the strings have more tension the pace will be less pace (slower) With this understanding the balls could work the same way. In which case the ball that's newly open is more stable and that's what we call is an old ball is not deflated but more inconsistent in its bounce.

Your examples are way off base.

Best, most informative video on this subject. Hands down. Just inherited a lake property with a shallow well and need to get up to speed on that whole system. Thank you for all the good information.

Sometimes defensive driving is a bad things as we become more conscious than required, our focus is just on one thing but it increases the error possibility (especially true for those who can't handle stressful situations) as focus consumes a lot of energy and it also slows down our decision making capability.
