Yes, drain stoppers do come out. In some cases, you can twist them counterclockwise to remove them. You can lift some drain stoppers halfway to the raised position and unscrew them. For others, you will need to lift the drain stopper to the raised position and unscrew the stopper from the stem underneath the top of the stopper.

Yes, a toilet, sink, and shower can share the same vent. This is a common plumbing practice that can simplify installation and save space. When sharing a vent, it's important that the toilet is located downstream from all other fixtures. You will also need to ensure the vent pipe is large enough to handle the demands of all connected fixtures without compromising its effectiveness. Because requirements can vary, you should always check your local building and plumbing codes. Consulting a qualified plumber is recommended to ensure the vent is properly sized, installed, and adheres to all local regulations.

Emergency plumbers charge a significantly higher rate than for standard service, typically 1.5 to 3 times the normal hourly cost. You can expect to pay between $100 and $500 per hour, with an average of around $200 per hour. In addition to the higher hourly rate, many plumbers charge a flat emergency service or trip fee, which can be between $150 and $300. The final cost depends on the timing of the call; prices are highest for major holidays, followed by weekends and after-hours service on weekdays. For a complex job on a major holiday, a master plumber's rate could reach as high as $600 per hour.

The best place for a kitchen sink drain is the middle of the sink. Most people prefer center drains because they allow for better water and waste drainage, and the center location limits splashing because water flows straight down the drain hole. If the sink drain is too close to the edge of the sink, water can collect and drain too slowly. It can also be easier to clean sinks when the drain is closer to the center since debris is easier to wash down and doesn’t collect along the sides as easily.
