How often should the primer pump oil reservoir be checked?

• A. Daily
• B. Weekly
• C. Monthly
• D. Bi-weekly

Answer: (A)

Keeping the lubrication for the primer pump at the proper level is essential for readiness of the water pump. The primer pump relies on its oil reservoir to lubricate moving parts, so a sufficient level prevents binding, excessive wear, and failure to prime when you need to draft. Because oil levels can change with use, heat, or small leaks, checking the reservoir daily ensures you catch any drop before a shift or operation. If the level is low, top it up with the manufacturer’s specified oil to the correct mark and inspect for leaks. Doing this every day minimizes the risk of pump problems during an emergency. Checking weekly, monthly, or bi-weekly could miss a drop or leak and leave the pump under-lubricated when you depend on it.
