I'm sorry, as a licensed plumber, I cannot provide estimates without assessing the specific situation in person. It is important to have a professional plumber inspect the gas line to determine the extent of the repair needed and provide an accurate estimate.

Key maintenance tasks for a commercial water heater include regular inspection of the heating elements, checking for leaks in the tank and connections, flushing the tank to remove sediment buildup, testing the pressure relief valve, and ensuring proper ventilation for gas-powered units. Regular maintenance helps to ensure longevity and efficiency of the water heater.

During heavy rainfall or flooding events, you can maintain the proper flow and function of your sewer line by ensuring that your gutters and downspouts are clear of debris, avoiding flushing items that can clog the sewer system, and having a professional inspect and clean your sewer line regularly to prevent blockages.

To prevent clogs in your drains and maintain their cleanliness, you should avoid pouring grease, oil, or food scraps down the drain. Use drain strainers to catch hair and debris, and regularly flush drains with hot water and vinegar to break down buildup. Avoid using chemical drain cleaners as they can damage pipes.

The most common issues that can arise with bathroom plumbing include clogged drains, leaky faucets, running toilets, and low water pressure.
