Not every home has a sump pump, but this can be one of the most labor-intensive plumbing repairs. I recommend calling a plumber if you aren't comfortable with doing any sort of electrical work. Always unplug the motor before doing any work. Be sure to double check with your local building inspector before making any major changes to your sump pump system.

I think it is rather rude and a bit dishonest for people to not divulge their total fees upfront, an of course we should know to ask. But the normal person wouldn't know the questions to ask until they are burnt once like this, and then there still could be costs for walking up stairs or charge another service call if they need to go somewhere to use the bathroom and come back. THAT ISN'T A QUESTION I WOULD THINK TO ASK.

Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.[1] Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.[2] The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.[3]

While it’s their job to make sure your pipes work like a well-oiled machine, it’s not their job to rebuild the wall they had to demolish to make that happen. So, while you’re going to get that water problem fixed, you’ll want to discuss in detail what kind of “mess” they might leave behind prior to the start of the project so you can plan accordingly. Remember, there are some jobs you can do yourself. Here’s how to solder copper pipe joints!
plumbers must be asked directly what they charge hourly and if that is in addition to a service charge. The two are separate and I think they have gotten away with outrageous charges because of the potential of water damaging homeowner structures.   I had a plumber (not Home advisor) come and replace a part in my kitchen sink that was under warranty---the spray nozzle had been leaking...He charged me $85.00 for 15 minutes of work and I will never use Mr King again. 
Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago. US cities began using hollowed logs in the late 1700s through the 1800s. Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil")[21] out of steel, copper, plastic, and cast iron.[21]
Similarly, there's no shortage of different types of sinks, too. These range from spare single-bowl models starting under $100 to a farmhouse apron front, double bowl made of copper or cast iron that can run $600 or more. Some are mounted under countertops — called undermount sinks — while drop-in sinks are designed for installation in a preexisting space in your countertop. Whatever the type, sinks can uniquely complement kitchen design as do countertops, cabinetry and other features.
Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies, and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.
