Rule Bilge Pumps RM500B Editorial Review
Product The Rule Mate Fully Automated, Water Sensing Bilge Pump is a convenient and efficient solution for keeping your boat or bilge area free of water. With its automatic sensing feature, the pump activates and evacuates water as soon as it detects it, ensuring a dry and safe environment. One of the standout features of this pump is its test button, allowing users to check its condition with ease. By pressing and holding the test feature for 5 seconds, the pump will operate, giving users peace of mind. The size dimensions of the Rule Mate pump are 2.85" in width, 5.08" in length, and 4.38" in height. This makes it suitable for narrow bilge spaces while still providing powerful pumping capabilities. The pump offers different discharge port sizes depending on the model. The 500GPH and 800GPH models have a 3/4" discharge port, while the 1100GPH model uses a 1" or 1-1/8" port. Additionally, the pump operates at either 12 volts or 24 volts, depending on the model. The Rule Mate pump is easy to install and works reliably, as reported by many satisfied customers. However, it is important to note that there have been some reported issues with the automatic float switches in the Rule 1100 model. Some users have experienced failures of the switch, forcing them to rely on the manual button. This issue seems to be more prominent with the 1100 model specifically. Overall, the Rule Mate Fully Automated, Water Sensing Bilge Pump is a reliable and efficient solution for keeping your boat or bilge area dry. Its automatic sensing feature, test button, and compact size make it a practical choice for boat owners.
