My electrical panel is full. Can I swap out some breakers for tandems to add a generator interlock?

You might be able to. Some panels allow tandem breakers only in specific slots, or not at all. Check your panel's interior label for 'CTL' or 'No Tandems' markings. Installing a generator interlock and its wiring needs a licensed electrician. They ensure it meets local code and secure any required permits.

My new faucet cartridge has different port shapes than the old one. Is it okay to use it?

No, if the port shapes are different, it's not the correct cartridge for your faucet. Even if it looks similar, different ports mean it won't seal properly or will restrict water flow, leading to leaks or poor performance. Always get an exact OEM match based on your faucet's make and model number to avoid issues. Using the wrong part will just cause more headaches and another trip to the hardware store.

My downstairs water pressure just dropped significantly. What's the usual culprit?

Sudden pressure loss downstairs often points to a specific issue with that line or its fixtures, not the main supply. First, check any dedicated shut-off valves for the downstairs area; ensure they're fully open. Next, unscrew and clean the aerators on all affected faucets downstairs, as mineral buildup is a common culprit. If those simple steps don't restore pressure, you might have a blockage in the branch line or a failing pressure-balancing valve in a shower, which would require a professional to diagnose and fix properly.

My energy monitor needs Ethernet. Is it okay to run that cable inside the electrical panel?

That Ethernet cable is for low-voltage data from the energy monitor, not high voltage. The monitor itself uses current transformers (CT clamps) around your main wires. Installing any device or running any cable inside a live electrical panel requires a licensed electrician. There are specific rules for cable type, routing, and access to prevent hazards and maintain code compliance.
