This is a difficult question to answer because the amount of time it takes to unclog the main sewer line can vary greatly depending on the severity of the clog. A simple clog might only take a few minutes to clear, but a more serious clog could take hours or even days to fix. If you're experiencing problems with your main sewer line, it's best to call a professional who can assess the situation and provide a solution.

If you detect water on the floor, your first instinct should be to find the source of the leak. Once you've identified the source, take whatever steps are necessary to stop the leak. If the leak is coming from a plumbing fixture, turn off the water supply to that fixture and call a plumber. If the leak is coming from a pipe, you may be able to fix it yourself by using a sealant or plumbing tape. However, if the leak is coming from a hidden pipe or fixture, it's best to call a professional.

There is no set answer to this question, as the frequency of repiping will vary depending on a number of factors, such as the age of your home, the type of materials used in the plumbing system, and the quality of installation. However, most experts recommend having your home's plumbing system inspected every 5-10 years, and repiped if necessary. Generally speaking, most homes should be repiped every 20-30 years. If you're unsure whether or not your home needs to be repiped, it's best to call a professional.

There are a number of things that can cause a toilet to back up into a tub, but the most common culprit is a clog in the sewer line. If your toilet is backing up, it's likely that there is something blocking the line and preventing the wastewater from flowing down the drain. The best way to fix this problem is to call a professional plumber who can clear the clog and restore normal drainage. Other possible causes of this problem include a blocked or overflowing drain and low water pressure.
