How can I tell if my house has three-phase power?

Most homes have single-phase 120/240V power. Look at your main electrical panel; you will usually see two thick service cables plus a neutral entering it. A three-phase service would have three or four thick service cables coming into the main breaker. This setup is rare in residential homes and requires a licensed electrician to identify or work on.

Dropped something in the toilet, now it's clogged. How do I get it out?

First, try a quality flange plunger; sometimes a good seal and a few pushes can dislodge it. If that fails, get a toilet auger, also known as a closet auger. These are designed to navigate the toilet's trap without scratching the porcelain and can often hook or push the object through. Do not use a regular drain snake, as it can damage the bowl. If the auger doesn't work, the object is likely lodged firmly in the trapway or further down the drain. Your next step is to carefully remove the toilet to access the obstruction. If you're not comfortable with pulling the toilet yourself, call a licensed plumber. They'll have the right tools and can properly reinstall it with a new wax ring.

My door jamb is damaged. What should I check?

If the jamb damage is around the strike plate or near the doorbell, check for exposed wiring. Wiring for electric strikes or doorbells often runs there. If wires are visible or cut, turn off power at the breaker. Call a licensed electrician to inspect and repair.

My ceiling fan switch box has white wires just capped off. Is this okay?

No, capped-off white wires in a switch box are usually not okay. White wires are neutrals, needed to complete circuits and power many modern switches. If these are unused, the wiring is likely incomplete or incorrect for your fan. An electrician needs to inspect this. It could be an old switch leg setup, but it may also be unsafe or prevent proper fan operation.
