Frequently Asked Questions - BOAC-3/4 Truper

How do I prime the BOAC-3/4 water pump?

Remove the priming plug and fill the pump casing with water until it overflows. Replace the plug and turn on the pump. The pump should self-prime within a few minutes.

What type of liquid can this pump handle?

This pump is designed for clean water only. Do not use with flammable, corrosive, or abrasive liquids.

Why is my pump running but not delivering water?

Check that the pump is properly primed, the suction line is not blocked or leaking, and the foot valve is operational. Also ensure the discharge valve is open.

How often should I clean the strainer?

Clean the strainer after every 50 hours of use or whenever you notice a decrease in flow. Remove debris carefully to avoid damaging the filter.
