Frequently Asked Questions
Q: What tank does the AML7-58-08001 drain plug fit?
A: The AML7-58-08001 is a drain plug assembly compatible with Tennant M17 and M20 recovery tanks. It fits the bottom outlet of the dirty water tank. Verify your tank serial range before ordering, as some regional variants use different plug diameters.
Q: What is the thread size of the AML7-58-08001?
A: The AML7-58-08001 has a 1.5-inch NPT (National Pipe Thread) male connection. The plug body is approximately 2.25 inches long with a quarter-turn ball valve design. Confirm the threaded inlet on your tank is 1.5-inch NPT before ordering.
Q: What material is the AML7-58-08001 drain plug made from?
A: The AML7-58-08001 body is cast brass with a stainless steel ball valve seat. The handle is injection-molded black polypropylene. Brass resists corrosion from acidic cleaning solutions and mineral buildup. The stainless ball prevents pitting and ensures a reliable seal over thousands of open-close cycles.
Q: How do I know if the AML7-58-08001 is leaking and needs replacement?
A: A faulty AML7-58-08001 will drip or stream water from the valve body when the tank sits overnight. The handle may also rotate without fully closing the ball inside. Water leaking around the plug threads indicates a cracked body, which cannot be repaired. Replace with a new AML7-58-08001 to prevent floor damage and water loss during recovery tank storage.
Q: What is the flow rate of the AML7-58-08001 drain plug?
A: The AML7-58-08001 is rated for 40 to 50 gallons per minute when fully open. A 20-gallon recovery tank drains completely in approximately 30 to 40 seconds. Do not force the handle past full rotation, as this can damage the internal ball valve stem.
