Parts may be superceded when models are upgraded, so please make sure you have the serial number of your product available to avoid unnecessary delays. The serial number on your machine can be located on (or near) the tow coupling (image shows location of serial number on an older irrigator).

Please note that the five different models of irrigators have a different letter or letters in front of the number, e.g. the Spider has S then the number, the Deluxe has DL then the number, Super Spider has SS, Super Duper has SD and the Greenback has GB then the number. This number and letters are important to match the right part to the irrigator and have have changed over the years but we have the changes in our history.
