It depends on the location and the plumber. Some plumbers may charge by the hour, while others may charge a flat rate for the installation. Typically, the cost for installation will be somewhere between $100 and $300. It's always a good idea to get quotes from multiple plumbers before making a decision.

The cost of hiring a professional to install a sump pump will vary depending on the plumber's hourly rate and the cost of the pump itself. However, as a ballpark estimate, you can expect to pay between $100 and $200 for labour plus the cost of the pump.
