Customer had concerns about the work we installed due to water moisture on the ground underneath the entire house I can’t find anything that would cause the water on the ground. they say maybe it’s because the house doesn’t have gutters so I ran a test on the system and We installed which was the tub and overflow we ran water to see that there were no leaks. so our portion of the job is fine I would imagine the gutters have something to do with the moisture under the house. Homeowner was happy and content with what we saw. Also I check all other plumbing to see if something old may be leaking but I didn’t discover any water leakage. They were happy and content on our diagnosis.
