Start with what the faucet is doing
Before you buy parts, name the symptom. A drip from the spout is a different problem from a leak behind the wall, and a weak shower is different from a tub that will not hold hot water temperature.
Most tub faucets drip because a rubber seal or cartridge inside the valve has worn out. Water then slips past even when the handle is closed. This is the most common and the most fixable case.
If you are not sure what you have, send us a photo and call (630) 822-9290. Brand and handle style tell us a great deal.
| What you notice | Likely cause | Who usually fixes it |
|---|---|---|
| Drip from spout when off | Worn cartridge or washer | Homeowner or plumber |
| Water stays at spout during shower | Worn diverter | Homeowner or plumber |
| Hot and cold mixing is off | Cartridge or mixing valve | Plumber if corroded |
| Weak flow at one handle | Debris or scale in the valve | Homeowner or plumber |
| Leak behind or below the wall | Joint or pipe failure | Plumber |
The usual culprits
A compression faucet has separate hot and cold handles with rubber washers that squeeze against a seat. When the washer hardens, the faucet drips. Replacing the washer and checking the seat often fixes it.
Single handle faucets use a cartridge, a ball or a ceramic disc. These last longer but fail when grit or scale builds up. The handle is hard to turn or the temperature wanders before a drip starts.
The diverter is the part that sends water to the shower head. When it wears, water keeps pouring from the spout while you shower. Some diverters are a pull-up knob on the spout, and some are a third handle.
Weak flow and uneven temperature
If only one handle runs weak, debris or scale may be blocking the cartridge inlet. Taking out the cartridge and rinsing it sometimes restores flow. If both handles and the shower head are weak, check the shower head screen and the other fixtures before blaming the tub valve.
Temperature that swings when someone flushes a toilet points to the mixing cartridge. Some cartridges include a pressure balancing part, and that part wears. It is a small piece, but it is also a safety feature against sudden hot water, so replace it with the right match.
Safe steps you can try
Turn off the water at the tub's stop valves if you have them, or at the main shutoff for the house. Open the faucet to release pressure and put a towel over the drain so a screw does not fall in. Take photos at each step.
Pry off the cap on the handle, remove the screw and pull the handle. Remove the trim plate and look at the stem or cartridge. Many cartridges lift out with a pull or a clip release. Take the old part to a hardware store so you can match it.
Put everything back in reverse order, turn the water on slowly, and check for drips. Keep the work to what you can see and reach.
When the repair is not a simple swap
Some valves are stuck so hard that pulling the cartridge risks breaking the valve body. Others have no access panel behind the wall, which means any deeper work needs an opening cut in the wall. These are plumber jobs.
Do not use a torch or cut into the wall unless you know what you are doing. A broken valve body that cannot be shut off can flood a bathroom quickly.
Replacing a valve is plumbing work under the Illinois Plumbing Code (77 Ill. Adm. Code 890), the standard the Village adopts. A new valve should be set to that standard, not just patched until the drip stops.
If the shutoffs do not close, or you cannot find them, call Call (630) 822-9290. We can also tell you whether a faucet repair or a full valve replacement makes more sense for your age of home.
What the Village water means for your tub faucet
The Village of Hoffman Estates buys Lake Michigan water from the City of Chicago. Its 2025 Water Quality Report lists chlorine as the disinfectant at an average of 1.2 ppm and reports no drinking water quality violations for 2025. The report does not print a hardness figure.
That matters for your faucet because hardness is what builds scale inside a cartridge. Since the Village does not publish a number, test your own tap with a kit or ask Public Works before you decide on a filter or softener. Recurring stuck cartridges every few years is a clue worth telling your plumber about.
Preventing the next repair
Use the handle gently. Cranking it hard against the stop wears the seals faster. If one handle feels gritty, fix it early before the seat is scored.
Run the tub faucet every week or two if the bathroom is rarely used. Valves that sit dry can stick. And if you replace a faucet, choose a cartridge brand you can still find parts for.
For houses with older valves, a full valve replacement during a bathroom remodel avoids repeat repairs. Call (630) 822-9290 if you are planning a remodel and want the valve checked first. For a sink or kitchen faucet, see our faucet and sink repair page.
What affects the price of a bathtub faucet repair
Parts for a faucet are small, so the total comes from access, the age of the valve and whether anything is corroded. We give the price by phone before the work starts, once we know the brand and the symptom.
What changes the price
If your faucet is old enough that parts are hard to find, replacing the valve may cost less over time than another repair. Call (630) 822-9290 and ask us which makes sense.
When to call a plumber
Call if water drips inside the wall, if the ceiling below stains, or if the faucet will not shut off at all. Call if you cannot stop the water. Close the main shutoff valve, open a lower faucet to drain the line, and call (630) 822-9290.
If water is near an outlet or light fixture, keep away from it and switch off power only if you can reach the panel while dry. Otherwise stay out of the room and call an electrician or emergency services.

The Village's 2025 water quality report does not list a hardness number. Test your tap with a kit or ask Public Works if you need an exact figure.
A small drip means a seal or cartridge is slightly worn. It wastes water over time, so it is worth fixing.
Only if the tub has working stop valves. If it does not, use the main shutoff and consider adding stops while the wall is open.
If the shower head trickles while the spout runs full, the diverter is not sealing. A new diverter or spout often fixes it.
Usually not, unless water is leaking into the wall or ceiling. Shut off the water and call if you see staining.
