    You do not need to bother with the fancy fitting at the bottom. Just stick the tube in the top, tape it and then siphon it out. The level will still be the same as the level in the bucket. Also, I tape the end tubing to the edge of a yardstick with high numbers on the bottom. That way higher numbers will mean a higher elevation. Actual numbers do not matter; only the difference from the reference matters. Use a few drops of dish detergent to kill the surface tension.

    Quick Southeastern Ohio history lesson. In the 1940's, the Soil and Water Conservation Districts started helping farmers set up contour lines in their fields to help mitigate soil erosion in our considerably rolling hills. They used a hose pipe (as my great-grandfather called it), and two glass tubes (remember, clear plastic hose really wasn't a thing in the 1940's) on either end to make their water level to lay out contour plow lines. They used a setup very similar to this one shown here. The beauty of this over using a transit of any sort is that one man alone could lay out the contour lines by himself. With a transit, it always took two people. A soil technician could mark out the lines, generally with white painted tomato stakes, then leave. Afterwards, the farmer could come along, and all he'd have to do is line up the nose of his tractor, or the hames knob of his horse team's harness with the white painted stakes and be off to the races with his new soil conserving contour lines in his fields.

    Amazingly useful information. I remember watching this video when it first came around and having this idea introduced to me for the first time. Well now 5 years later I needed to set some footings for a deck and needed them to be all the same height and I remembered this video and was able to apply this very concept 5 years later. I just felt the need to come back here leave my thoughts even if it’s very unlikely anyone will ever see this comment.

    Back in 1967, I was an apprentice carpenter, Local 906 Glendale sold us carpenters water levels at a reduced cost. Most of us had one. The water reservoir has space in it to store the hose. The water part sealed up tight so that you didn't loose the water over time, it also allowed the micro air-bubbles to escape. I used that thing hundreds of times, they are more accurate than a transit-level.

    I agree. Very simple explanation. The reservoir sitting over on the fence is smarter. Ive only seen the fluid in the tube on both ends on other videos. I seen this in use 30 years ago. Thanks to TH-cam i found how to do it again. Great video

    I built a water level similar to this one to level a 24’x 25’ metal building concrete foundation form! Instead of using a white sticks like he used in this video I used a sheet rock T square with the inch marks on it. I was able to set my baseline and then measure up and down an eighth of an inch at a time. Yes it works very well. So well that a friend of mine came out with a laser level and checked my work and it was just as accurate as the laser level.
    I also used it to level the shelves in my wife’s closet before I installed them.

    Pro tip: you can use a cheap 4 ft level that also has ruler measurements on it instead of the white stick. using one will give you an easy way to tell how “off” something is by reading the difference in measurements.

    So I am building garden boxes, a green house, gazebo and a chicken coop. This morning I inventoried my materials and then stood with my saws, and work tables all set up wondering how in the heck I could get everything level. I can build furniture on a flat floor, no problem. Tried leveling the first tier of the garden box that is 25 feet long with my 3 foot level. The headache and frustration for trying to connect each short level to the last short leveled section! The garden box is not so critical, but the other fixtures need to be square and level. I knew there had to be a better way! Researching on TH-cam I found laser level instructions. $300? Ok amazon has some for less...$60. Now I start reviewing how well they work and how long they last. How long will it take to have one delivered, etc. Then I found your video! What a money time saver! I’ll have everything laid out in just a couple of hours and be confident to start my projects! I cannot thank you enough!

    great video. this is one of the better water level howtos i've seen on youtube. i think i'll try making one with extendable hose lengths for work. i think some people could confuse "square" with "a square" (whice you probably accidentally said in the video). a 10x12 foot shape with equal diagonals is a rectangle. if your outer edges are not equal you will find a discrepency in the diagonals and you will have a parallelogram or quadrilateral - where adjacent sides are not square. the video makes sense to me but i do it all the time for work. great video anyway!

    Water tube levels are brilliant, I have one, just a long length of polythene tube. A couple of things I would mention. If part of the tube has been lying in the sun the water in that part can heat up a bit and will then have a lower density to the water in the colder part of the tube. This will put the readings out, however it may be possible to allow for this. The other thing is I always check the level before AND after using it by bringing the two ends of the tube next to each other. Then if there are bubbles or different densities it will show. Good video

    One way to get it pseudo square before you measured diagonally each direction is to measure down One direction 3-foot the ninety-degree angle measure down 4 ft and then in between the two measurements it should be 5 ft. It's called the three, four, five rule. That way you won't have to do a lot of adjusting once you start measuring diagonally. It's a helper

    True "the environment changing'' from day to day will effect the calibration. AKA temperature and barometric pressure. The key to circumventing this natural occurrence, Is why a "station point'' was designated. Station point is the height you wish to maintain of the finished product. If the reservoir is placed at the same station point every day, and allowed to acclimate to the environment, then it will self calibrate. If the station point is higher than the finished product height, you would measure down from the water level to determine how far your finish product height is below your water level height. Using boards with yards sticks and tubing attached to, makes this process much easier. Using wind shield washer fluid, allows this system to be used below freezing temperatures, because it will not freeze

    There are some limitations to this method: it won't work over huge distances because of differences in barometric pressure. It also isn't completely precise because the earth's gravity changes slightly depending on geology. However, the way it's demonstrated in this video shows a perfectly valid way to use this technique.

    Just made one of these to check for view blocking and base level for the HUGE shed I am about to have built. Using hose pipe, the hozelock cone shaped sprayer works as a valve and I have it poked in the 3/4 inch internal diameter clear hose I am using for seeing through, attached to 20 metres of garden hose with a jubilee clip. Fixed join at the other end is the nozzle from a caulking gun, cut down and pressed by hand into the hose pipe to give a rigid core. Then built up with electricians tape, then shoved in the 3/4 inch clear tube and secured with a jubilee clip. I should be able to close the sprayer nozzle, those yellow long cone things, to move around, then open it slowly to get to let water move to get level. In case I judge wrong I don't want to be over topping out the tube all the time. Measuring over 100 meters in stages with 20 meters of garden hose. Should be fun...

    When I built my 10x16 shed 25 years ago,, I used a rifle scope taped to a 4-foot bubble level for one end, and a vertical yardstick at the other end.. It was what I had handy :-) Now, I need to replace support posts on a 50-foot porch and want something more accurate than the bubble level (carpenters' level), so I'm planning to put together a water level to be sure the porch roof beam is kept level as I go.

    tire valve, pop in thick container for fast seal outlet. Long neck valve is best and clamp on hose.
