Bathroom Faucet Repair in Salem, MA

What this page covers

Bathrooms have more faucets than people think. There is the sink, often two of them, the tub spout, the shower valve and sometimes a bidet or a separate hand shower. Each one has its own kind of valve and its own way of leaking. This page walks through the common problems, which ones you can check at home and which ones to leave to a plumber. It is general guidance for homes in Salem, Massachusetts. It is not a quote.

Bathroom sink faucets

A bathroom sink faucet is lighter duty than a kitchen faucet but it still wears out. The usual problems:

A drip from the spout. Worn cartridge, washer or seat. In a bathroom the drip is often quiet enough to go unnoticed for months, leaving a rust or green stain in the bowl.
Leak at the handles. Worn O-rings or a loose packing nut, especially on two-handle faucets.
Slow drain-and-fill. Can be the faucet aerator, but can also be a stopper or pop-up assembly that is clogged or misadjusted.
A leaky pop-up drain. The drain assembly under the sink has a pivot rod and a nut that can seep. It is often mistaken for a faucet leak.
Loose faucet. Mounting nuts under the vanity loosen over time.
Water under the vanity. Supply lines, shut-off valves, drain trap or the faucet. Check each connection with a dry tissue.

Vanity cabinets are usually thin particleboard. A leak under the sink can swell the floor of the cabinet quickly, so it is worth acting even on a slow leak.

Tub spouts and shower faucets

A tub spout that drips or will not shut off. If water keeps trickling from the tub spout, the valve behind the wall is worn. Replacing a cartridge or a stem is normally a small job and does not require opening the wall.

A shower head that drips after use. Usually the same worn valve, but it can also be a clogged head. Some drip is normal as the pipes drain after use, but a steady drip that lasts for minutes is not.

A leak around the handle or the trim plate. Water reaching the wall behind the handle means the valve seals are worn or the trim is not sealed. This needs prompt attention, since water in a wall causes damage out of sight.

A diverter that does not hold. If water comes out of both the tub spout and the shower head, the diverter is worn or dirty. On many tubs the diverter is built into the spout and can be replaced alone.

Water pressure that fades or temperature that swings. Often a failing pressure-balancing or thermostatic cartridge. Sudden hot or cold bursts are worth fixing for safety.

A ceiling stain below the bathroom. A leaking tub or shower valve, drain, or waterproofing failure. This is one of the situations where waiting costs money.

What you can safely check

Aerator and shower head. Unscrew them and soak in vinegar if crusted with scale.
The stopper in a sink. If it is not sealing or sticking, see if it needs cleaning or adjustment.
Under the vanity. Dry each connection and watch for the first wet spot.
The caulk and grout around the tub and shower. Failed caulk can leak even if the faucet is fine, and water in a wall may be coming from there instead.
The cabinet floor and the wall below. Check for soft spots, stains and a musty smell.
The shut-off valves. If your fixture has its own, find them. If not, find the main.

If the drip is from the tub spout or the shower and you have no access panel, avoid taking the handle apart yourself unless you know how. Cartridges can be stuck and trim parts break.

Access panels and walls

Many tub and shower valves are reached from behind through a panel in an adjacent closet or hall. In many older houses there is no access panel. A plumber may have to cut a small opening in the wall to reach the valve, and that adds work for a tiler or a drywall repair. Ask about this up front so there are no surprises. Where there is no panel, ask the plumber whether the repair can be done from the front, as many cartridges can be.

Repair or replace

For a sink faucet the logic is the same as in a kitchen. Repair when it is newer and a single part has failed, replace when it is old, corroded or leaking in several places. For tub and shower valves replacement is a bigger job because the valve is inside the wall. A cartridge swap is common. A full valve replacement is done when the valve body is corroded or when parts are no longer made. If you are planning a bathroom remodel anyway, mention it, because it changes what makes sense.

Costs and what changes them

This website does not set prices. The things that usually change them:

Sink faucet or tub and shower valve.
Repair of a part or replacement of the whole fixture.
Whether the plumber must open a wall and who closes it again.
The type of valve and whether parts are still available.
Condition of shut-off valves and supply lines.
The faucet you choose to install.
Time of day and day of the week.

Ask how the price is calculated before you agree and whether there is a visit fee.

Bathroom plumbing in older Salem homes

Many Salem bathrooms were added to older houses long after the houses were built, often squeezed into a small space with whatever plumbing route was easiest. That can mean short supply lines, odd valve locations, cast iron tubs on old drains and a mix of copper and galvanized pipe. Behind tile there can be a valve that has not been touched in fifty years. Plumbers who work on older houses are used to this, but it explains why a bathroom job can run longer than expected.

If you rent, tell your landlord and keep a record of the date you reported the leak. If you live in a condo, check whether the shut-off for your bathroom is in your unit or shared.

Safety

Hot water: the shower valve controls scald protection. If your temperature is unstable, fix it sooner rather than later, especially with children or older adults in the house.
Electricity: bathroom outlets and fans near a leak are a hazard. Do not touch wet electrical parts.
Slips: a wet tub or floor is a fall risk.
Mold: any wall or floor that stays damp for days should be dried and checked.

Preventing the next bathroom faucet leak

Replace rubber or old supply lines under the vanity when you replace the faucet.
Recaulk the tub and shower when the caulk cracks or lifts.
Clean shower heads and aerators a few times a year.
Do not over-tighten handles.
Run a fan after showers to cut humidity.
Look under the vanity once a month.

Frequently asked questions

Why does my tub spout keep dripping?

A worn valve cartridge or stem behind the wall is the usual reason. It is a common repair and often does not need the wall opened.

Why is my bathroom sink faucet leaking at the handle?

The O-rings or the packing nut around the handle stem have worn or loosened. A plumber can replace them or the cartridge.

Is water behind the shower wall a big deal?

Yes. Water in a wall can damage wood and drywall and grow mold without being seen. If you suspect it, call soon.

Why do I get water from both the spout and the shower head?

The diverter is worn or dirty and does not hold. It is often replaceable on its own.

Can I fix a bathroom faucet myself?

Cleaning an aerator or tightening a nut is simple. Replacing cartridges inside a wall is harder, and a mistake can cause a larger leak.

Who does the work if I call this number?
