The amount of water in the tank simulates the weight of the boat and crew, the more water in the tank the heavier the boat and crew. We recommend the following levels:
Level 12-14 for children
Level 14-17 for women
Level 16-19 for men
The WaterRower comes shipped complete with a syphon pump for ease of filling or emptying the tank.
To fill the tank or add water; simply place a container of water onto the top of the machine, insert the stiff tube of the syphon pump into the container of water and the flexible tube through the hole in the WaterRower tanks, pump couple of primes by hand and let gravity do all the work.
To empty the tank or remove water; simply place an empty container by the side of the machine, insert the stiff tube of the syphon pump into the WaterRower tank and the flexible tube into a container or outside, pump a couple of primes and again gravity does all the work.
