Best Tank Or Tankless in Phoenix AZ

We had water leakage in master bath and ceiling was moist. Zoltan was out the next morning within the committed time frame. He tried his level best to re-produce the problem but unfortunately we were not able to re-produce it. He shared his number with us and told us to call him back the moment we see the leakage again. He was super professional and polite the entire time. I would highly recommend Laszlo Plumbing to anyone needing plumbing services.
