    July 2026

    Poseidon Plumbing did a great job and I highly recommend them. David, Jax and Lucas replaced parts to fix several leaks. When two small leaks remained, David took the time to thoroughly diagnose the issue, returning multiple times, calling the manufacturer, testing water pressures, and carefully troubleshooting until he found and repaired the root cause. His expertise saved us tens of thousands of dollars by diagnosing the actual problem instead of jumping to a costly conclusion. Jax even handled the required tile trimming.

    Jax came out to look at a possible leak noted in an inspection report. He was super friendly and efficient and was honest about what did and didn't need fixed. Will definitely use these guys in the future, probably the best customer service I've ever had from any plumber.
