    Our main sink in our student house took forever to drain. We called Superior Plumbing, and Mark came out the same day. He used a ginormus snake and the work was completed almost instantly. Thank you !

    My water heater was making rumbling noises that didn’t sound normal. Stella flushed the tank to remove sediment buildup and inspected all components. The noise stopped completely, and performance improved noticeably.
