Symptom: This kitchen faucet sprayer nozzle was leaking at the connection to the hose every time the tenant pulled it out of the hole in the faucet plate.
Conclusion: The tenants thought that because they were no longer using sprayer nozzle, it was no longer leaking. What they didn’t realize is that just because they couldn’t see it actively leaking, there was constant water pressure through the hose to the nozzle from below the surface. The water continued to leak causing damage to the cabinet below.
