Laser level vs Water level | Which is more accurate?
Ойын-сауық
While the crew from WD Metal Buildings were putting up the metal frame for Barndominium 203, they used their water level to mark all the pipes to establish a level benchmark. I decided to set up my laser level and pin both levels against each other. The results were shocking!

I'm reading alot of comments about the time needed for a water level. Starting to think if I wanted cheap and quick. I'd buy two long lengths of tubing. Affix two of them together. Then move one end to a spot where you need marking. Then move the other tube to another spot. Hopefully, by the time you've affixed site 2 ... site 1 has settled down for marking, then move it to the next point. Return to the other tube and mark and move. Cheap and possibly just as fast.

@@Ga7cun7sSUCK - Just as in the video. The error is not from the water level per se. It's operator induced! That's a given. Physics don't change. On the other hand operator's patience, capacity, whatever, varies a lot! ;-) With this said I would go with a laser. - IF I didn't have to pay for it! ;-) - IF there was a multitude of continuous work, that justified it! Other wise for a couple of measures the water level would be just fine. After all most backyard projects only need a few measurements. A "pro" doing it all day long, day in day out. That's another story!
Seems like someone was just in a hurry with their water level marks, I've used water in a pinch several times it's always dead on

You can check the accuracy of the lazar level using the two peg method, most people don’t know how to do this. I’ve found brand new lazar levels to be inaccurate. A water level doesn’t need to be checked and is always right on if you are patient enough to wait for the water to settle out. To two peg a level set up two posts 50 feet apart. Set the level up in the centre. Shoot both posts and measure the difference. Move the level 50 feet away from the pegs and shoot them again and measure the difference it should be the same. If it’s not you can see if it’s shooting up or down.

Interesting video I stumbled on here. I am a metal stud drywall guy,and I actually started in the trades in Texas,and we used a water level all the time,back in 1983 the lasers were not yet as available as today. I think since there was only 1 discrepancy, it could be the mark made on the pipe was slightly off...But yes,the water level is the bomb,just keep the air bubbles out.
If you add petcocks to both ends of the water level, and shut them "off" before moving the water level, you will have much less bounce to the water, as you wait for it to settle in the tube. I have been building boats for 36 years. A water level is what we always use to level our multi-million dollar boats. Another choice to use for liquid to use in a water level is, non-toxic antifreeze.

Petcock or cork is perfect for storage and transportation of the water level! But for it to level quickly, covering and releasing the tube with your finger in a quick succession will stop it in no time! With some practice it's surprisingly fast! ;-)
I have used both pretty extensively the laser you need to check calibration every so often. The water level wind will make a difference sometimes the upwind side will have a higher pressure then the downwind side causing your levels to be off a little bit. The laser level can be a one-man operation easier than a water level but if one end of your water level is attached to a bucket filled with water it can be a one man operation also. A very good laser level can have a range from one side to the other of almost a thousand feet a water level is limited to probably about 150 to 300 feet. A water level has its advantages in that you can level easily underneath structures and in any room. It is probably wise put a small amount of detergent in the water used in a water level to do away with the surface tension of the water. Don't use too small of a hose because the surface tension will make a difference. I always used a garden hose with a clear section of hose at the end to get my levels I always put a valve on it also so that when I transported the end from one location to the other I didn't lose any water. High tension power lines, strobe lights like those found on emergency vehicles, arc welders and anything that reflects light like large glass windows that business sometimes have will play Havoc with your laser level receiver. Get too close to an automobile that has a real shiny finish can be a problem too. If you have more than one laser level on a job site or nearby you can get some very erroneous readings also. You don't have those problems with a water level. However you can have problems with heavy equipment running over your hoses. If you do not need a level very often a water level is probably far more cost-effective. So in summary they both have their advantages and disadvantages. You can get very good results out of both of them. A water level is a very good tool for surveying caves and mines. Another pretty good low tec level is a speed square and plumb bob but it is not nearly as accurate as a water level. The best level that I have ever used was a split bubble Wild made in Switzerland it was so sensitive that just switching your weight from one foot to the other even on solid concrete would cause the bubble to move slightly.
That project is going to be beautiful. Great pick on your contractors.. Thank you for sharing. Texas Barndominiums!!
There are a couple of ways to use a water level by yourself. The first is when you have the two ends together fix the stationary end to a post etc then mark the waterlevel on the tube, when you are at the marking end you have to make sure the water is at the line you marked and it will be at the line on the fixed end. The quickest method is to drill a hole in the bottom of a bucket and silicon one end of the hose into the bucket, fill with water, mark the hose with a line and when marking make sure water is at the mark. The bucket reservoir will dampen the water movement in the hose and make it settle much quicker.

Wow Erik! Great video yet again!
Like most scenarios I have seen at job sites, the true test is repeatability, which level works more often? My guess is, in a more exhaustive test, both levels are going to perform very well, and it is most likely, human error that accounts for differences. An example, if you measure something 10 times and 9 measurements are the same, and one is not, the measure that is not the same, it is usually due to human error, and not the tool.

I think the water level is spot on every time. You mentioned the con for water levels; they’re slow because you have to wait for the water to settle. Someone else also mentioned lasers are line of sight- the only limit on a water level is how much hose you have available. Something else to consider...does the laser level need to be calibrated occasionally?
As a 70 year old now retired from the trades I witnessed many Masonry and Tile craftsmen in hospitals installations use the water levels over Lazer’s.
thanks for the video
Let it settle and the water level will be as accurate as the meniscus of the water in the tube. Add a bit of dishwashing soap and the meniscus will decrease, giving even more accurate measurements. The laser will expand slightly over distances, so when you are marking your levels, you need to ensure that you are marking the exact center of every laser dot / line. If you are needing to mark a single reference point throughout a house where there will be walls blocking a clear line of sight, the water level will work better. If you wanted to see if the slab of your house is at the same level throughout your house, the water level would be a better choice.
The water level should be perfect, except when it gets hot and bubbles form. The laser beam can get larger at distance and they all have tolerance that increases errors with distance.
I’ve used one many times! Always accurate!
thank you for sharing.
In the summer months in FL the laser would droop on which ever side the sun WASN'T shining on. Thermal expansion was the cause.
Awesome video amigo! Water of course!!

Great video. I like using my water level just so people can ask me “what the heck is that”. I love telling them my level cost $25.00 and then hear them say they spent $1500 .
Never heard of a water level. So clever
I love it. My laser level is easy to use early in the morning, not so much in the middle of the day. This water level is impressive and a heck of a lot cheaper.
Been using an inexpensive one for years, needs salt water for conductivity as it's electronic, gives of the same beeping sound as the laser receiver.. pretty spot on, claims +/- 1/8th" in a hundred feet. Great for starter courses around corners when working alone.
I put a valve on each end of hose so I can close the ends till the next time I need it. Fast and accurate and with valves no mess or need for water on site.

It's pretty impressive that that it's only off by 1/8" at that one location. I think the error could have easily been additive. For the water mark, it may have been off by 1/16" in one direction, and the laser mark could have been off by 1/16" in the other direction (1/8" total).
Used water level 80s-90s. First lazer had double bubbles to level. Would need to keep checking to make sure the laser was still plumb. Finally got a self leveling laser which works great!

The 1/8" would be easy to get just by marking mistakes. the pencil is 1/16" thick :) the laser relies on charged batteries and the ability to mark the notch accurately. My money is on the water level especially since you have the wiper fluid in it to reduce bubble and friction. I have worked with many lasers in 40 years and they can be fussy :) setup time is reduced with the water level also, nice video.

I've used the water level, laser and jig transit for layout before. For simplicity, the water level wins. For speed and accuracy, the laser wins, for absolute accuracy, the transit is king. The laser is a productivity tool. A single tradesman can set up a laser and mark all the locations inside a work space in minutes. A water level is a low skilled tool that works well within the limitations of the length of the tubing you have access to.
I love using water levels and for the cost comparison its well worth the little wait of water balancing.
Old tried and true methods are often the best. Technology doesn't always make things better.
I've used water levels a lot on building site especially on relocated house's projects when there 2 or 3 sections and working from 1 datum point Lazer's can't see through plaster sheeting or as America's call drywall.

Most Lasers have a discrepancy of 2 to 3 mm either side of true level ? Therefore one needs to move the Receiver and observe a height mark on the work, when it's at it's highest point just before it starts to beep periodically, and then do a second mark after moving the Receiver down slightly until the continuous beep changes to a periodic beep at it;s lowest point. Once You find this range, then it is simply mark the centre point between both marks giving You True Level and a more accurate reading ! Hope this helps !

Due to curvature of the earth the laser will lift off the horizon 1' inch in 660' feet. If you shoot laser across a 660'ft pond, the water level will be an inch lower on the other end. A water level will differ from laser by 1/10"in every 66'ft
You can't beat the economy of the water level. The ends of the water line should be shielded from the wind for the best accuracy and stability. Thanks for comparing these two methods.
Both the water level and the laser level are great tools. A person that does sloppy, careless work, or is not properly trained, could make either tool inaccurate and could seriously screw up a job.
Great video! The only reason I would give the win to the laser, is if you have joker coworkers and somebody steps on the water level while you are marking points.
Somebodies getting their walking papers today👀
I think it was margin of error. I brought my laser lever back, and got one with a better receiver. Now it works like a champ
It's more likely some parallax error while hand marking. Laser beam with shoot straight on very long distances until the beam spread its beam and loose accuracy ,the construction will be an inverted trapezoidal. The water level will follow the Eath curvature and make you produce the same curve on your construction. In the absolute,the water level is more accurate,just because we live on a big ball,and not on a flat surface.
If you use multiple hoses with "central bucket" then there is no significant difference in speed. You only need clear tubing at the end of you lines. Rest can be done with heavy duty and/or cheap hose. Water works in all lighting conditions, in mist, dust, round the corner and at any distance... and no level of abuse will ever throw it off the calibration!! You can wack it around your truck, throw it around work site, drive over with digger and drop it from the roof with no worries. Accuracy is guaranteed by nature. After you done all hose fit inside the bucket so storage is comparable to the laser set - with the difference in cost and fragility of the system ;)
The concept of the water level is sound. Looking at the product specs. of laser levels will show a small variance in accuracy. This variance will magnify the further away from the source. That said. I have never had much luck with the water level. I think it's the operator :-) The best tool is only as good as the operator.

The laserlevel is perfect for the initial leveling. If you are in a masonry house you already have walls in the way of your laser, so you would need to reset the height on the laserlevel for every room to get the same height. With the waterlevel it's easy to get the level in different rooms all across a house... I say there is no right tool for every job in the world...

For some reason laser levels are typically advertised +-1/8”. With water levels, it not only needs to settle but have any air bubbles expelled. Also, the water and the tube can expand and contract with heat and cold. And if some water drips out or is removed it needs to be recalibrated.

Air pressure can make tricks to the water level, that is difference in air pressure, like wind blow into one end of the pipe/hose and the other end is on the opposite side of where the wind hits the object you are measuring at (this create a small vacuum compare to the real air pressure). An other thing can be temperature of the water in the pipe/hose, if you start with cold water in the morning and the pipe/hose lay in the sun during the day it will heat up and expand, if you do not recheck with your reference point then this can trick you too.
Very interesting. I wonder if a water level was used to build the Egyptian Pyramids?
When using water level check for bubbles, for they will affect the level. Before using water hose do a level test like you did, put the hoses side by side to check calibration. I filled the hose with RV pink antifreeze, worked great at first, the next year it was off an 1", I'm thinking the additives in the RV antifreeze separated.
I had never seen that kind of a water level. The only thing I have seen is the floating transit(bowl with floating aiming piece) which is more like a LASER level in use.
