Q: What is your "Optomizer" valve?

Prospecting-Red-2

A: This valve allows the pump to be positioned at extreme angles simply by turning the valve to compensate. As long as the pivot point is facing up the exit valve is optomized. We use this valve on our submersible model.

Q: My pump plunger seems hard to stroke, how can I make it easier and smoother?

A: There are two plastic tension washers inside each leather cup. Try loosening the lock nut a turn or two or it may be necessary to remove one of tension washers from each cup. This is very unusual and mostly happens with international orders. A 1/2in. wrench is all you need.

Q: After I place my order how long before it ships?

A: We build pumps all the time and will usually ship on the next business day. Please allow 3 days just in case something comes up.
