The gist of it is 50ft hose or less, use 5/8 diameter. Anything longer, use 3/4. Got it.

You explained water hose size diameter,length,flow rate and water pressure real good.

Thank you so much for making this video. I have been through about 6 water hoses within 10 years and wanted something that would last.

Really helpful video. I've been loving the simplicity of your channel. Thanks so much!

I could listen to you for days! Thanks for the video. I've learnt something new today. 🤣

Thanks for taking time to explain in such detail. It answers all my questions. Thank you!

Love your view of the backyard

Super helpful video packed full of info. Love the tests you ran.

Just what I needed to solve my problem. Thanks!

👏🏽👏🏽👏🏽 Great video Brother! You covered this topic like a KING. Thankyou So Much.

Excellent demonstration

Wow what an awesome video thank you very much for the time and effort really answered a lot of questions I had 👍👍

it would be interesting to see the pressure difference between a 3/4 and a 3/8 tube. good video.

If you wanna take a really deep dive on the topic, google firefighting hydraulics. Water flow and hose friction loss are life/death topics for firefighters.

Outstanding advice. You confirmed my purchase five years ago when I spent a lot of money buying 3/4" hoses instead of what the "locals" were advising. My Montana "lawn" is two acres around the house and stretches around forested trees in a park-like setting. Our main house water spicket has two (2) splitters to accommodate four (4) outputs where each outlet travels 200-300 feet to a "water zone". At each water zone I have a splitter where two of the 100 foot zone hoses take the water further. AT the end of each hose is an Orbit (Rainbird) Impact Tripod sprinklers. To ensure that each water zone will work, I have installed at the source house output four (4) Orbit Timers so that there are no more than two spinklers running at one time until their timer ends and another timer begins. This also permits me to water at odd hours so as to not draw down neighbor pumps using the same water table and aquifer. Again, you're a champ for validating what I believed. This year the cost of a 100 foot 3/4" hose has doubled in cost but at least I own them. (I have 16).

Right. I do WFP window cleaning. Industry standard uses 5/16, I use 3/8 because I use spray bars and 3/8 gives better pressure and flow to fill bar. Same with my pumps. If I use pole hose or 1/2 hose my pump works hard and draws over 10 amps. Use a larger hose to supply water then use pole hose my pump is hardly working. Always use the larger hose if possible. Friction loss sucks.

Wow this was great info! Thanks!

Fantastic information! Thanks.

Thanks for the video. Take Care.

Great explanation! I’m convinced :)

Excellent video

Awesome detailed analysis! I Always wonder exactly what the diff/ benefits were. Matt Morman at obsessed garage did a test on pressure washers and pressure washer hoses with quite surprising results, very informational thanks!

Awesome content !

Friction Loss and Flow is the Difference!

Well done!

Really usefull video, thanks. Can i ask what pump are you using?

Thank you!

Man, you got a kick-ass water supply!!

Thanks

100% it works

Good info thank you 🎉🎉🎉🎉🎉

After use converted air line tubing on my outdoor faucets kept blowing regular garden after a pressure test found out that there is no pressure regulator and was getting 180 PSI at the faucets.

Wonder what the flow would be. Like how long it takes to fill a bucket with each length. Please test and share.

If I have 2 orbit impact sprinklers that work great with 2 but not with 3 do you think that swapping out my 5/8 hose for a 3/4 hose would allow for all 3 sprinklers to work?

Interesting.

My water supply line is 1/2 inch. Am I wasting money buying a 3/4 hose? Is the limiting factor the sully line? I think my flow rate is about 3.5 gal per minute through the spigot.

If you put a spray nozzle on the end, won't that change all of this and finally determine the actual flow rate/pressure? Regardless of the hose diameter, the final step down 1/10" or whatever is the actual tiny hole the water has to try to get out of. In the same way that water from the main line in the street is very strong (fire hydrant) but in your house, it is relegated to that 1/2". Also, like a speaker or a light bulb. They may be rated to X number of amps but only use what the device is capable of. A chain is only as strong as it's weakest link. With an open end, yes, 3/4" might flow more volume but not sure when you put a nozzle on it.

Be curious to dee this on my laen with one big sprinkler 125 ft away on a low yiled well..

Would you lose pressure with a larger diameter?

I would murder for that kinda water pressure 😂

I would love to try out a medium quality 5/8 inch hose and a 50 foot would be adequate for what I need here. Thank you very much. If you’re only giving away 75 foot hoses that would work as well

An external fire hose is what people need so if your house is on fire you can put it out, if ya don't believe me just look here on You Tube. Also for hot water supply to sink kitchen and bathroom I would like to see a video on how much faster the hot water would get there with a smaller supply line.

hmmmm maybe I am missing something here. The hose pressure should be the same if the hose fluid is static. Isn't that what you did?...deadhead the hose with the gauge? With no flow, the pressures in all parts of the hose will be equal to the extent that all parts of the hose are on the same level.

Shouldn’t the static water pressure be the same irrespective of the size or length of hose? There is no friction loss when the water is not moving.

How does this apply if it’s already coming from 1/2 spigot

I appreciate your video. Lots of good details there. One question that still remains for me though.... the 5/8" and 3/4" hose were able to attach to the 3/4" spigot without an adapter? So the size of the threads is the same for both sizes of hose?

Thank you so much, Sir! Does the flow rate get affected if I connect quick disconnects?

Is your red 3/4" hose a true 3/4" i.d. at BOTH ends. (I'm only asking because I just bought that hose and the fitting on the input end is choked down to 5/8".) I'm trying to find a full 3/4" ALL the way through. Thanks, and great video. I never calculated the length and friction.

Damn I just learned a lot. Thank you!

I may be wrong but it’s not up to friction that slows the water down of a longer pipe. Over the length of the long pipe, there will be less pressure due to you having to fill the pipe with more water. It acts like a big tank. The result pressure will be reliant on how many sprinkler outlets you have on the hose. So a smaller diameter hose that is lengthy may never build up enough pressure required to come out of the sprinklers . Basically, the hose is acting as a tank. In its most simple form, a longer run you need a large diameter hose because the sprinklers will require a minimum amount of pressure to activate to their potential. If you have a lot of sprinklers on a small pipe, your low pressure water supply is not enough to meet the total sprinkler output. One cheap way around is to use a large diameter pipe to feed most of the water to its destination, then just before you branch off to the sprinkler you use a smaller diameter pipe. This is similar to forcing a large tank of water (large diameter pipe) through a small pipe that will have to theoretically meet the large diameter pipes water flow. The result is higher pressure at the final sprinkler outlet. Of course there are other factors such as if you end up having too many sprinklers, you’ll never build up enough pressure to keep up with that initial low pressure water supply.

Static pressure should be the same no matter the length of the hose. Can you explain the loss of pressure when everything is in equilibrium and there is no flow?

Who knew water hoses would be so interesting

Add a booster pump at the source.

Poiseuille's law. In medicine this is important for rapid transfusion/infusion. To maximize flow you need the widest diameter but also the shortest length of tubing. If you control for the length of the tubing as he did in the video then the radius of the tubing is the only variable and it is very clear that 5/8 inch hose will deliver far less flow. It might not matter much if the hose is short. But for anything beyond about 50 ft. or if it is being used on an irrigation system with several sprinklers, 3/4 inch is really the only way to go.

RAIN GUN SPRINKLER

Anyone know where on earth I can get 5/8 inch (preferably pvc) caps for a garden hose? Male and female. I want to completely close off both ends because I want to fill it with water or sand to add some weight to it and use it as a battle rope for workouts. I can't seem to find this size cap anywhere.

Are you reading the gauge right?

What about if you connect it to your house tap which is powered by half inch hose.

1/8”!

My friend. There is no such thing as overkill.

Does he live in canda or something? Ive never seen or heard of 5/8 garden hose lol

lots off pressure

an 1/8 inch, duh

Uuuuh, 1/8"....? Is this a trick question???

Now do it in metric so I can understand.

Waste of water trying to keep grass in desert areas

Very boring. Put me to sleep.

Which hose. Should I use because since I have low pressure coming out of my outside faucet for my garden hose(trying to have bette r pressure coming out of it )
