What size pipe do I need to plumb a bathroom?

• <div><p>You’ll need two sizes of pipe to plumb a bathroom. You’ll use a 1/2-inch pressure pipe for your supply lines that run from the fixture to the larger 3/4-inch supply lines that run through the house. For drain lines, you’ll need a 3-inch PVC pipe for your toilet, a 2-inch PVC pipe for stand-alone showers, and a 1 1/2-inch pipe for a shower/tub combo and the bathroom sink. Each fixture’s drain will run to the 3-inch main drain that runs through the house.</p></div>

Can you put Drano in a sink with standing water?

• <div><p>While you can put Drano in a sink with standing water, most plumbers don’t recommend doing so. It usually doesn’t help to clear the clog, and you’ll end up with a sink full of standing water plus a toxic chemical—which is very unpleasant to deal with and best handled by a professional.</p></div>

What day is the busiest for plumbers?

• <div><p>When it comes to weekday work, the busiest days for plumbers are Monday and Tuesday. Part of the reason is that people discover plumbing problems over the weekend but wait for weekdays to help save money. </p><p>As for the busiest day ever, many plumbers point to “Brown Friday,” their nickname for the day after Thanksgiving. A day of guests, lots of food, and unfamiliar bathrooms can often lead to plumbing disasters, making that Friday a hotspot of emergency plumbing work. Follow our holiday tips above to avoid becoming a statistic.</p></div>
