Toilet runs or refills by itself
A worn flapper or tired fill valve wastes water all day and quietly raises a Prince William Water bill.
Plumbing Repair — Triangle, VA 22172
Most plumbing repair is not an emergency, and that is exactly why it gets postponed until a drip becomes damage. This page covers the everyday fixes: faucets that drip, toilets that run, valves that weep, traps that leak, and fixtures that have simply worn out in Triangle homes and rentals.
24/7 line for urgent problems. Scheduled visits for everything else — honestly sorted on the first call.
A scheduled repair starts with a useful description. Which fixture, what it does wrong, and when it started tells us most of what we need: a toilet that refills by itself points to a flapper or fill valve; a faucet drip that speeds up month by month points to a worn cartridge or seat; a damp cabinet floor points to a trap or supply connection, not the faucet above it.
Call (855) 913-0016 and walk us through it. We will tell you whether it is a straightforward repair, what to watch in the meantime, and whether closing a fixture valve is wise while you wait. Renters: reporting the small drip early is what keeps it from becoming the ceiling stain your deposit gets blamed for.
A worn flapper or tired fill valve wastes water all day and quietly raises a Prince William Water bill.
Cartridge or seat wear that a new washer may not cure if the sealing surface itself is scored.
Trap joints, supply connections, or a disposal flange weeping into the cabinet — three causes, one wet shelf.
Mineral scale in an aerator or cartridge, common with moderately hard water, rather than a house supply problem.
A failing pressure-balance cartridge that scalds or chills when another fixture runs.
The little valve under the fixture, seized from years without use, discovered exactly when you need it.
Pipes knocking when valves close fast — a pressure or loose-pipe problem that stresses joints over time.
A hose bib worn inside its wall section, wasting water and threatening a winter split.
A repair visit should end with a fixture that works, a cause you understand, and no mystery about what was replaced. Here is the shape of ours.

Small symptoms repay early attention. This table translates the common ones into likely causes and sensible timing.
| Symptom | Likely cause | Urgency | Next step |
|---|---|---|---|
| Toilet tank refills every few minutes | Flapper leaking through or fill valve worn | Same-week — water waste adds up | Book a repair visit |
| Drip from faucet spout, one per second | Cartridge or seat wear | Same-week — seats score further | Book a repair visit |
| Damp cabinet under sink, no visible drip | Trap or supply weep under flow | This week — cabinets rot quietly | Limit use; book promptly |
| Banging when the washer stops filling | Water hammer, high pressure or loose pipe | This month — joints fatigue over time | Ask for pressure check |
| Shutoff valve under sink will not turn | Corrosion and years of stillness | At next repair — replace proactively | Mention it when booking |
Wear is chemistry plus repetition. Triangle's moderately hard water, sourced from the Occoquan Reservoir, deposits scale inside cartridges and on valve seats, so seals that should glide instead grind. A family bathroom's shower cartridge may cycle thousands of times a year; add mineral grit and the sealing surfaces score until no washer change restores a clean shutoff.
Rental turnover accelerates a second pattern: fixtures in a quick-turn rental get used hard, cleaned with whatever is at hand, and reported late. A disposal abused by a departing tenant, a flapper chain kinked during a rushed clean — small things that surface for the next household. A between-tenancy repair pass is how landlords break that cycle, and it is some of the most cost-effective work we do.
Good repair work tests before it disassembles. We run the fixture through its paces, check supply pressure at the angle stops, dye-test a toilet tank to prove a flapper leak, and inspect a trap with a dry-paper test that shows exactly which joint weeps under flow.
That discipline matters because symptoms impersonate each other. Low pressure at one sink is usually scale in that sink, not a failing main. A 'leaking faucet' is often a leaking supply line below it. Replacing the wrong part is how a simple repair becomes a saga, and it is avoidable with ten minutes of testing.

Most modern fixtures repair at the component level: a cartridge, a flapper and fill valve, a trap assembly, a pair of supply lines. We stock the common sizes for the fixture brands Triangle homes actually contain, including the builder-grade models installed across Potomac Highlands and the older two-handle sets still common along Old Triangle Road.
When the fixture body itself is scored, cracked, or obsolete enough that parts are discontinued, replacement becomes the honest repair. We explain the point at which another component swap stops making sense — usually when the sealing surface, not the seal, has failed — and let you choose with the old part in view.
Neither answer is always right. Age, parts availability, and the condition of the sealing surfaces decide it.
| Situation | Recommended path | Why |
|---|---|---|
| Fixture under ten years old, common brand | Repair the component | Parts are available and the body is sound |
| Sealing surface scored or body cracked | Replace the fixture | New seals cannot seal against damaged metal |
| Obsolete fixture, parts discontinued | Replace, and note the model change | A repair you cannot repeat is a poor investment |
| Rental between tenants, several small faults | Repair in one pass, replace the worst fixture | One visit resets the unit for the next tenancy |
Call the same day if a supply line under a sink is actively spraying, a shutoff valve itself is leaking, or a toilet leak has reached the floor around its base — wax-ring failures let waste water into the subfloor with every flush. A water heater's relief valve discharging repeatedly is also a same-day call, since it signals pressure or temperature trouble, not a tired valve alone.
Everything else on this page can be scheduled calmly — and scheduling it, rather than forgetting it, is the whole point.
With Marine Corps Base Quantico next door and a large share of Triangle households renting, repair work here often involves three parties: the tenant who found the problem, the landlord who authorizes the fix, and us. Clear paperwork is not bureaucracy in that triangle — it is how a tenant gets a working shower without a week of phone tag, and how a landlord in another state knows the bill was for a real failure.
Townhome layouts add a physical wrinkle: stacked bathrooms share walls and chases with the unit next door, so a 'leak in my ceiling' repair may start with a knock on the neighbor's door. We are used to coordinating that politely and documenting which unit's fixture caused what.
Straight answers, tested work, and a written summary — anywhere in Triangle, VA 22172. Call (855) 913-0016, any hour.

How It Works
You explain what you are seeing; we ask the questions that sort urgent from schedulable and tell you any shutoff step worth taking now.
We test before we touch: pressure, meter, camera or fixture cycles — the evidence comes first, in view.
You hear what failed, why, and the repair paths with their costs — including the option of a smaller fix where one honestly exists.
The repair is completed and then proven under pressure or full flow before anything is closed or covered.
What failed, what was done, what to watch — documented for owners, landlords and tenants alike.
Exercise your shutoff valves twice a year — a quarter turn each way keeps them from seizing. Clean faucet aerators when flow drops instead of forcing handles harder, and replace toilet flappers at the first phantom refill rather than after a season of wasted water.
Between tenancies, landlords should run every fixture, flush every toilet twice, check every trap with a dry hand, and photograph the water heater's label for its age. That twenty-minute pass finds most of what would otherwise become the new tenant's first-week repair calls.

Why Consider Us
Triangle turns over fast. Families arrive on orders, renters rotate each summer, and landlords carry keys for houses they may visit twice a year. Triangle-Plumber is built for that rhythm: short, clear explanations, written notes a landlord can act on from another state, and a pre-move walk-through habit that catches the dripping trap and the tired water heater before a new tenant finds them the hard way.
We also say plainly what is not ours to fix. A Prince William Water main issue, a shared townhome line owned by the HOA, a fixture a tenant damaged — you hear who owns the problem and what the next call should be, instead of a bill for guesswork.
Turnover is when plumbing problems surface. We check shutoffs, traps, disposals, and heater age at the moment a home changes hands, so surprises land on a checklist instead of a first night in a new place.
We explain, in plain terms, which repairs usually sit with the property owner and which day-to-day items sit with the tenant — then document the finding so both sides read the same note.
A meter test, a pressure reading, or a camera view comes first. The repair follows the evidence, and you see that evidence while we talk through the choices.
Call (855) 913-0016 at any hour. You get shutoff guidance for the situation in front of you first, then a visit matched to how urgent the problem actually is.

FAQs
Water is slipping from tank to bowl, almost always past a worn or warped flapper, and the fill valve tops the tank up when the level drops. A dye tablet in the tank proves it: color in the bowl without flushing confirms the path. Replacing the flapper, and the fill valve if it is the same age, ends the phantom refills and the wasted water on your Prince William Water bill.
Yes — a drip a second adds up to hundreds of gallons a year, and hot-water drips also burn energy heating water nobody uses. The bigger cost is often the fixture itself: the longer a scored cartridge drips, the more it erodes its seat, turning a component repair into a fixture replacement. Early is cheaper in both water and hardware.
It becomes one the day you need it. Angle stops seize from years of stillness and mineral contact, and forcing one can start a leak at its stem. Replacing seized stops during any nearby repair is inexpensive insurance. We check them on repair visits and flag the stiff ones before they matter.
Tenants should report problems promptly and can always call us for diagnosis and to stop damage. Authorization for the repair bill usually sits with the landlord or property manager under the lease. Our written summary — cause, photos, and the fix — lets an out-of-state landlord approve quickly, and lets the tenant show they reported the issue in good time.
Older shower valves lack pressure balancing, so a toilet refill steals cold water and the mix swings hot — or a modern cartridge's balancing spool has scaled up and stopped moving freely. Triangle's moderately hard water makes the second cause common. A cartridge replacement usually restores steady temperature; we test the valve's behavior before and after so you can feel the difference.
It is worth fixing. The bang is a pressure shock wave, and repeated shocks fatigue joints, loosen pipe supports, and shorten appliance valve life. Causes range from high street pressure to a failed expansion tank or hammer arrester. We measure your home's pressure during the visit — a gauge reading turns a mysterious noise into a specific, fixable cause.
That is one of the best uses of a visit. Landlords and sellers often hand us a punch list — two drips, a running toilet, a stiff stop, a slow trap — and one trip clears them all, with one written summary. Batching shares the travel and diagnosis time across every item, which is why a between-tenancy repair pass is such good value.
We will show you the issue directly: discontinued cartridges and odd-size stems eventually make a fixture unrepairable. At that point replacement is the honest path, and we note the old and new models on your paperwork so future repairs start with the right information. We never declare a fixture dead without demonstrating why its parts cannot seal or be sourced.
Usually the faucet itself: scale and debris collect in its aerator and cartridge, especially with moderately hard water. If pressure is low at every fixture, the cause sits upstream — a pressure regulator, a partly closed valve, or the service line. The pattern is the diagnosis: one fixture means local, whole house means system, and the fix follows the pattern.
Disposal leaks, jams, and flange problems are kitchen plumbing, covered on our kitchen page, but a repair visit can absolutely include a disposal check — especially between tenants, when foreign objects love to turn up in the chamber. Tell us when booking and we will plan the visit to cover both rooms in one trip.
Close the fixture's shutoff valve if it works, keep a towel or tray under an active weep, and stop using a toilet whose base rocks or leaks — every flush pushes water into the subfloor. Then book promptly: most 'meanwhile' damage happens because a manageable drip was left for a month, not because it was severe.
The fixture and component that failed, the likely cause, what we replaced, the tests we ran, and anything we noticed that deserves watching — a tired supply line, a heater approaching its label age, a stop that is starting to stiffen. Owners keep it for records; landlords use it to close the loop with tenants; everyone gets the same plain language.
