Some plumbing symptoms are cosmetic annoyances; others are early notice of a failure that gets more expensive by the week. A toilet that runs intermittently is wasting water, but a toilet that rocks slightly when you sit down means the wax ring seal may already be broken — and that can damage the subfloor if it goes unaddressed.

The same logic applies to water heaters. A unit that takes noticeably longer to reheat, makes popping or rumbling sounds, or shows any rust at the base is usually within a year or two of failing outright. None of these are emergencies yet, but none of them fix themselves either.

A hidden leak rarely announces itself with a wet spot right away. The first sign is usually a water bill that climbs without an obvious reason — no new appliance, no extra houseguests, nothing that explains a 20 or 30 percent jump.

Before assuming the worst, check your water meter with every fixture in the house off. If the meter’s leak indicator is still spinning, water is moving somewhere it shouldn’t be, and it’s worth a leak detection visit before drywall or flooring shows visible damage.

A flat-rate quote should specify the work being done, the materials being used, and what happens if the job turns out to be more involved than expected once the wall or floor is opened. If a quote is vague on any of those three, ask before you sign — not after.

Be cautious of a quote that comes in dramatically lower than every other estimate you’ve gotten. The gap usually shows up later, either in the materials used, in what the visit doesn’t actually include, or in a change order once the work has already started.

• Ask whether the price includes permits, if the job needs one
• Ask what brand and grade of parts or fixtures are included
• Ask what voids the price — the answer should be short

Tankless water heaters are often marketed as a universal upgrade, but they’re not automatically the right call. A tankless unit can supply endless hot water, but it needs adequate gas line sizing or electrical capacity, and homes with multiple bathrooms running simultaneously may need a larger unit than expected to avoid a temperature drop.

A well-sized tank system, by contrast, is usually less expensive to install and simpler to service. The right choice comes down to household size, simultaneous usage, and how long you plan to stay in the home — not which option sounds more modern.

Before help arrives, the single most useful thing most homeowners can do is find their main water shutoff valve — and know it works — before they ever need it. In an emergency, minutes spent searching for a stiff or seized valve are minutes of active water damage.

If a pipe bursts or a fixture fails, shut off the water at the main, then the electricity to the affected area if water is near outlets or fixtures. Move anything valuable off the floor, and take a few photos before you start moving items — it makes any insurance claim considerably easier.

• Locate your main shutoff valve today, not during an emergency
• Know whether your water heater has its own shutoff
• Keep a wet/dry vacuum accessible for minor flooding
