Questions & Answers

Q: What is the best model for my application?

A: For a small, average yard, the Model A-5 will work fine. This sprinkler is designed to handle a standard 100 feet length of 5/8 inch rubber garden hose.

For larger yards, we recommend the Model A5-2. This model is designed to handle 150 feet of hose.

For very large estates and parks, we recommend the Model B-3. This model will handle up to 250 feet of hose. This particular model also has wider rear wheels, which make it a good choice for rougher terrain or traveling across an incline.

Q: Does the sprinkler come with an automatic shut-off feature?

A: The National Walking Sprinkler does not come with an automatic shut-off feature. Those customers that need that feature can purchase water timer shut-offs that attach directly to the faucet. These devices are readily available online, and at stores that sell lawn and garden accessories.

Q: My new sprinkler arms do not spin. What is the cause?

A: First thing to check is that the arms are installed so that they are parallel to the ground, and 180 degrees opposite from each other.

Second: Occasionally a new sprinkler will need extra lubrication during the “break in” period. Try liberally spraying the vertical brass shaft where it rides on the bronze bushings with WD-40 or similar penetrating oil. Doing this before each use will allow the sprinkler to spin more freely.

In the event that both of these things do not work, please email us.
