Sometimes it will just be a slow drip but if they congregate on the seal then there can be a steady stream of water that is let through the valve.
I am going to have to respectfully disagree with my friend Bang I use a Thermoplastic spring check valves which gives a positive seal even with no back-pressure
Note I made sure I used a marine engine check valve, the ones that are used in the lines that use Saltwater as the cooling medium
