  Which Pipe Laser should I choose:


Which pipe laying laser should I choose?

All the pipe lasers listed are of excellent quality, fully automatic, self-levelling, waterproof, and supplied with remotes for adjusting alignment and adjustable targets, all in sturdy, well built carry cases. Basic costs for quality brands are all much the same and service life should be at least several years.

The key differences are size and weight, self alignment, grade range, type of battery and ability to calibrate in the field.

The LEICA PIPER (Swiss) is the laser of choice as regards size and weight, being the only one to fit inside a 100mm pipe. 

The smaller size makes it easy to set up in a 90 degree poured invert; and since it does not block a 150mm pipe when set up inside the pipe, it is still possible to use a blower. This stabilises the temperature inside the pipe and thus stops refraction from causing the beam to drop which can have serious consequences particularly if the pipes are being laid to minimum falls.

Automatic control of grade has been available for decades but a pipe laser that will home onto a rod or stake for line has yet to be developed. The nearest thing is the Alignmaster option available with the 100mm LEICA PIPER 200. This facilitates second day set ups by homing onto the special target placed inside the last pipe laid but costs extra over the PIPER 100.

Since none of the pipe lasers listed have a manual option, they are all limited by the maximum grade range. The Topcon has the greatest at 40%.

The Leica Piper, Topcon TP, MCE and Geo Fennel all have NiMH batteries but Quante win the battery stakes with their QBL125 using Li-ion which is considered even better. All models have emergency 12v cables so if the laser dies; production can be resumed by hooking up to a car. Leads for charging from cigar lighters in the car are available as accessories.

The LEICA and Topcon models can be calibrated in the field or at home

Green beam or red beam. Red beam lasers have been successfully used for decades but the green beam is about 4 times more visible and hence has undoubted appeal. The downsides is increased cost, shorter operating time between charging and reduced life expectancy.


To counter the green beam, the Leica Piper has a winking light facility similar to the ones on pushbikes. Turning the beam on and off makes it twice as easy to see compared with a continuous beam.


Experienced operators have no problem with seeing the red beam whether winking or not by simply standing so the spot is in the shade.


The ability to retain calibration is perhaps the most important requirement of all. Unfortunately there is no specification for this key factor but all brands should retain calibration reasonably well depending on how roughly they are treated.   

  How to use a Pipe Laser:




A pipe laser is to provide a solid line to align pipes during construction and ensure that pipes are installed in a straight line. The laser can be used above the pipe to ensure that pipes are installed levelled with the ground, and it can be used through the pipe to ensure that the pipe pieces are aligned.




A pipe laser is hard to overestimate. In addition to being used to keep your piping aligned and sitting at a proper angle, a pipe laser has a multitude of layout related uses at a construction site. It can be used in place of strings to measure the evenness and alignment of any surface, not just pipes.




Because of its small size, a pipe laser has the benefit of fitting into places that a person could not normally fit into. It could be lowered into a sewer, for instance, and measure the grades of pipes that a person could not measure manually without digging.

How to use a pipe laser:


Set up the laser level next to the upper manhole, the manhole whose base is at a higher elevation. Spread the legs of the tripod into a triangle and drive the legs into the ground by stepping on the foot tabs. Put the laser level on the tripod and adjust the bubble level knobs until the bubbles indicate that the laser is shooting on a level plane. Put the receiver on the grade rod and turn on both the laser and the receiver.


Place the bottom of the grade rod in the trough of the outflow hole at the bottom of the manhole. Adjust the receiver up and down on the grade rod until it makes a constant beep indicating grade. Record the number the grade rod indicates. Walk to the next manhole with the grade rod, do not move the laser level, and shoot the grade of the intake hole trough. The second recorded elevation is a larger number than the first, even though it is at a lower elevation. Subtract the first number from the second and record the result.


Measure the distance from the outflow hole of the first manhole to the intake hole of the second. Divide the sum of the elevation difference by the length of the run between the two manholes. This calculation is the amount of fall per foot each pipe between the two manholes requires.


Place the pipe laser in the outflow hole of the upper manhole. Turn it on. Adjust the fall-per-foot calibration with the "Plus" and "Minus" buttons on the pipe laser to match your calculation. Remember, for fall, the number the laser indicates has a negative symbol in front of it (-). For rise, the number is positive (+). Once the correct value is entered into the laser, it self-adjusts and sends a laser beam down to the intake hole of the second manhole from its position at the first.


Place the laser target, it is simply a piece of Plexiglas with a pair of legs in the intake hole of the second manhole. Press the horizontal adjustment buttons right and left until the laser is centred in the bullseye of the target.
