I doubt it. If there is no leaks under the house, no dripping faucets, and the one-way valve was replaced, then I would look at worn flapper valves in the toilet tanks. That would be the only other place you could have a leak and not see it on the floor or ground, I know you said that the one-way was replaced but I would take it back out and clean it in a bucket of clean water. very possible to have debris from shipping or manufacturing inside. Did you replace brass valve a brass one? I have had one failure of a brass model. I've since switched to PVC valves exclusively.
