The answer to 'sump pump no hot water' is that a sump pump is used to remove excess water from a basement or crawl space, and has no connection to the home's hot water system. If you are experiencing a lack of hot water in your home, the issue is likely with your water heater or the hot water plumbing, not the sump pump. Common causes of no hot water include a malfunctioning water heater, a broken heating element, or a problem with the hot water pipes. To troubleshoot and resolve the issue, you should inspect your water heater and hot water plumbing system.
If you are comfortable doing so, you can try simple DIY troubleshooting steps like checking the water heater's thermostat and heating element. However, for more complex issues or if you are not confident in your plumbing skills, it is best to call a professional plumber to diagnose and repair the problem.
