Start with the toilet, then confirm who supplies your water
Haverhill is a small town of single-family homes west of West Palm Beach, around Charlotte Street, Haverhill Road and Belvedere Road. A toilet problem can start with something a homeowner can see or hear: a tank that hisses and refills at night, water on the floor, a bowl that rocks, or a flush that will not clear. Those symptoms point to the same parts in any house, and that is where we begin. The utility question comes second. Check the provider named on your water bill before asking about usage alerts or billing questions. The county's neighborhood plan describes the area's historical use of wells and septic systems, and the town's spring 2025 newsletter included maintenance reminders for those systems. Neither establishes the connection at your home today. Tell us whether your property uses utility water or a private well and sewer or an onsite system, if known. Check property records or ask the utility when the connection is uncertain. A separate sewer bill or a shared meter can make the water bill alone inconclusive. That information helps distinguish a fixture problem from a concern beyond the toilet.
Why does my toilet refill when nobody has used it?
A short refill every so often, with no one touching the handle, means water is slowly leaving the tank. Usually it is passing into the bowl at the flapper or the flush valve seal. Sometimes the water level is set so high that it trickles into the overflow tube, or the fill valve does not shut off cleanly.
A dye check helps narrow it down. Put toilet dye in the tank, wait ten minutes without flushing, and look in the bowl, then flush. Color in the bowl shows tank water is reaching the bowl, most often at the flapper or its seat, though the exact part still has to be confirmed. A clear result does not rule out an intermittent leak or a fill valve problem, so we also watch the water level and the valve through a full fill.
Flapper, seat or fill valve: how we decide
We match the flapper to the toilet, since two-inch and three-inch flush valves and canister seals are not interchangeable, and we check the chain length so the flapper can close fully. We look at the flush valve seat for pitting or mineral crust that a new flapper cannot seal against.
For the fill valve, we watch where it shuts off against the water line marked in the tank and whether it hums, sticks or fills slowly. A slow or noisy valve may have debris at its inlet screen. Cleaning or replacing it is routine, and we explain which part failed before replacing anything.
Is the water on my floor from a seal, the supply line or sweat?
Dry the toilet and floor and watch a few flushes. Drops forming on the outside of the tank on a humid day are condensation, which is clean water. Our article on why a toilet sweats explains it. Water at the back near the wall points to the supply line or shutoff valve. Water that seeps from under the base after a flush points to the wax seal.
Seal water came from the drain, so treat it as unsanitary. Stop using that toilet, keep people and pets away, and call. Caulking around the base does not stop a seal leak and can hide damage underneath.

Why does my toilet rock?
A toilet that moves when you sit has lost its firm hold on the flange, the fitting that ties it to the drain. The movement breaks the wax seal over time, which can let wastewater under the toilet and cause a sewer smell.
Overtightening the bolts usually cracks the base rather than fixing the rock. The repair is to lift the toilet, check the flange for cracks or a height problem under the finished floor, repair it, and reset the toilet on a new seal. Shims can level a slightly uneven floor but do not fix a broken flange.
If the floor around the toilet feels soft or the flooring is lifting, mention it when you call. A seal that has leaked for a while can damage the subfloor, and that needs to be addressed before a new seal will hold.
Older shutoff valves and supply lines
In a home that has had the same bathroom fixtures for many years, the valve behind the toilet may not have been turned in a long time. If it does not turn easily, leave it. Forcing an old valve can snap the stem and turn a toilet repair into an urgent leak.
We replace seized or weeping valves and supply lines as part of the repair, using a connector matched to the toilet and valve and installed to the manufacturer's specification. A supply line that is swollen, rusted at the nut or cracked is worth replacing before it fails.
If your home is on a private well
If you receive no water bill, your home is likely on a private well. In that case a running toilet does not show up on a bill. Instead, you may notice the well pump starting when nobody is using water. Check the toilets first with the steps above. If the toilets all pass and the pump still cycles, the cause lies elsewhere and the well system should be checked by a well specialist.
One slow toilet or several slow drains?
A single slow toilet usually has a clog in its own trap. A flange plunger used gently clears many of them; stop if water rises toward the rim. If the toilet, tub and sinks slow down together, or the toilet gurgles when the washer drains, the blockage is farther down. Stop using water and call. On a property with a septic tank, a whole-house slowdown can also mean the tank needs service; if sewage surfaces, keep away from it.
Flush only toilet paper and waste. Wipes, hygiene products and paper towels cause clogs. Chemical drain products rarely clear toilet clogs and can harm the next person who works on the line. Our drain cleaning service clears house drains when the toilet itself is not the cause.
Repair or replace?
Most toilet problems are fixed with a new flapper, fill valve, supply line or seal. Replacement makes sense for cracked porcelain, frequent clogs in normal use or scarce parts. EPA notes that older toilets can use up to six gallons per flush, while WaterSense labeled models use 1.28 gallons or less and must meet performance criteria. Before replacing, we measure the rough-in and check the flange.
Ask the provider named on your bill about any current incentive before buying; eligibility and funding must be confirmed directly. Our toilet repair and replacement service handles installation, and current toilet coupons are listed separately and cannot be combined.
What to do when a toilet overflows
Stop flushing. Close the valve behind the toilet if it turns easily; do not force it. Keep children and pets away and avoid electrical outlets near standing water. If several drains back up, stop using water and stay away from any sewage.
Then contact Du-All Plumbing and tell us which fixtures are affected and when it started.

Before you call
Haverhill toilet repair questions, answered
How do I confirm who supplies water to my Haverhill home?
Check the provider named on your water bill. If you get no water bill, the home is likely on a private well.
Why does my toilet hiss in the middle of the night?
Water is slowly leaving the tank, usually past the flapper or flush valve seal, and the fill valve tops it up. A dye check and a look at the water level help confirm it.
Can caulk stop water coming from under my toilet?
No. A seal leak needs the toilet lifted and reset on a new seal. Caulk can hide damage.
Is a cracked tank something you can patch?
Patching porcelain that holds water is not safe. A cracked tank or bowl should be replaced.
My pump runs at night but my toilets pass the dye check. What next?
The cause may be elsewhere in the plumbing or the well system. Have the well system checked by a well specialist.
