Loss of Prime

When talking about a well pump losing it's prime and you need to re-prime the system.

Google translates:
การสูญเสีย ที่สำคัญ

Kār s̄ūỵ s̄eīy thī̀ s̄ảkhạỵ

Any confirmation from a knowledgeable person?

Cheers! :)

That reads as

Gaan soonseea tii samkan, which means a deterioration/ loss of that which is important.

Do you want to say "loss of pressure"?

Cheers, boys! :)

I'm aware of how to re-prime my 2hp water pump and have had to do it several times lately after changing over various manifold valves in the system. I wanted to be able to tell my water guy that I need a non-return or check valve in the line-up but he knew the English so all's well.

I've got very good pressure from this pump but for some reason when a remote valve is actuated down the line, backup flow causes the pump to lose prime.

Getting that much-needed non-return valve fitted tomorrow. :D
