How are valves tested to determine if they are leaking?
Valves are tested for leak-by to determine if they are leaking water when they have been commanded closed. There are several possible test methods, and the most appropriate one depends on whether the purpose of the test is to detect small leaks (15% of design flow or less) or large leaks after the system and component configuration is known.
What does it mean when your heart valve is leaking?
Any of the four valves can become leaky. This means that just after the heart squeezes and pumps blood forward, some blood will leak backward through the valve. Leaking through the valve is also called valve regurgitation.
What is a leakage of blood back through a valve called?

Can a check valve be in city mode?
Inexpensive and an easy fix. So, it means that even if the valve is in city mode that the water would go through the pump??? Yes, there is a check valve built into the pump, and as stated above it may be weak, defective, or just some debris in the valve, which can cause the situation you described to happen.
