Why does my toilet keep running?
A toilet keeps running because water is leaking from the tank into the bowl, or the tank keeps filling past the top. The usual cause is a worn flapper, a fill valve set too high or a chain that is too short. A running toilet can waste a lot of water each day, so fix it soon.
Quick checks before you call:
- Lift the tank lid and watch the flapper. If water keeps trickling into the bowl, the flapper is not sealing.
- Look at the water level. If it is spilling into the overflow tube, the fill valve needs adjusting or replacing.
- Check the chain. It should have a little slack, not hold the flapper open.
- Try the dye test. Add a few drops of food coloring to the tank. Color in the bowl after 15 minutes means a leak.
The EPA's WaterSense program lists running toilets as one of the most common household leaks.
Should you call a plumber or a handyman for a faucet or toilet?
Call a licensed plumber when the fix touches water lines, shutoff valves, the toilet flange or a shower valve inside the wall. A handyman can swap a toilet seat, but a bad wax ring or a cracked supply line can flood a floor. Our certified plumbers and certified techs fix the cause, not just the part you can see.
- Licensed: a plumbing contractor licensed by the California Contractors State License Board (CSLB)
- Certified plumbers and techs: trained on toilets, faucets, disposals, shower valves and outdoor fixtures
- Small jobs welcome: a single dripping faucet is worth a visit, and we treat it that way
- Many makes and models: we repair what you have and install the fixture you choose
- Experienced with Carlsbad homes: from older bathrooms in town to newer homes with modern fixtures
How do you know a toilet or faucet needs repair?
The most common signs are a toilet that runs or refills by itself, a faucet that drips after you turn it off, water at the base of the toilet and a toilet that rocks when you sit. Small signs like these get worse over time, so a quick repair now saves the floor and the fixture.
- A running toilet, or one that refills on its own with no one using it
- A dripping faucet in the kitchen, bathroom or tub
- Water around the toilet base, often a failed wax ring
- A wobbly toilet that rocks or moves when you sit
- A weak or slow flush, or a handle you have to jiggle
- A leaking outdoor faucet or hose bib, dripping at the spout or the handle
- A garbage disposal that hums, leaks or will not turn on
- A shower that drips after you turn it off, or swings hot and cold

What causes a toilet to run or leak at the base?
A running toilet is most often caused by a worn flapper, a failing fill valve or a loose chain. A leak at the base usually means the wax ring under the toilet has failed, the toilet is loose, or the closet flange that holds it is broken. Minerals in hard water can wear these parts faster.
What is a wax ring?
A wax ring is the seal between the bottom of the toilet and the drain pipe in the floor. It sits on the closet flange. When it fails, water and sewer gas can leak out at the base. A wobbly toilet often breaks the seal, so a rocking toilet should be fixed early.
Why is my shower dripping after I turn it off?
A shower that drips after shut-off usually has a worn cartridge or worn seals inside the shower valve. Hard water scale can speed up the wear. Replacing the cartridge often stops the drip without opening the wall.
What does it mean when a garbage disposal hums?
A disposal that hums but does not spin is usually jammed by something stuck between the plate and the ring, or the motor has tripped. Turn off the power at the switch before you check it. If the motor is burned out, the unit needs to be replaced.
Other common causes:
- Supply lines: the flexible line to a toilet or faucet can crack or bulge with age
- Angle stops: the small shutoff valve under a sink or toilet can stick or drip
- Hard water: scale wears washers, cartridges and flappers faster (see water softeners)

How is a toilet installed?
A plumber turns off the angle stop, drains and removes the old toilet, and checks the closet flange. A new wax ring goes on, the new toilet is set and bolted level, and the supply line is connected. Then the toilet is filled, flushed and checked for leaks. Most installs take a few hours.
- Inspection. We check the flange, the floor and the shutoff valve.
- Remove the old toilet. We turn off the water, drain the tank and bowl and lift it out.
- Flange repair. If the closet flange is cracked or low, we repair it so the new seal holds.
- Set the new toilet. A new wax ring, level bolts and a snug, even fit.
- Connect the water. A new supply line, and a new angle stop if the old one is stuck.
- Test. Several flushes, then a check at the base and the tank for any leaks.
- Haul-away. We take the old toilet with us and leave the bathroom clean.
How do you replace a kitchen faucet?
We turn off the water under the sink, disconnect the supply lines and remove the old faucet. The new faucet is set, sealed and tightened, and new supply lines are connected. Then we turn the water on, flush the lines and check for drips above and below the sink.
Already bought the fixture? We are happy to install a toilet, faucet or disposal that you picked out. We check that it fits your sink or space before the visit.
What fixtures and tools do we work with?
We install and repair low-flow toilets, kitchen and bathroom faucets, garbage disposals, shower valves and outdoor hose bibs. We carry common repair parts on the truck, so many fixes happen in one visit. When a part is worn out, we replace it with a quality, code-approved part that fits your fixture.
| Fixture | What we do |
|---|---|
| Toilets | Flapper, fill valve and flush valve repair, wax ring reseal, new low-flow toilet installation |
| Faucets | Cartridge and washer repair, new kitchen, bath and tub faucets |
| Garbage disposals | Unjamming, leak repair, new disposal installation sized to your kitchen |
| Shower valves | Cartridge replacement, pressure-balance valve repair or replacement |
| Outdoor fixtures | Hose bib repair and replacement, anti-siphon hose bibs |
What is a shower valve?
A shower valve sits behind the handle in the wall. It mixes hot and cold water and controls the flow. A pressure-balance valve keeps the temperature steady when someone flushes a toilet, which helps prevent sudden hot water.
Tools we use: basin wrenches, cartridge pullers, torque-limited closet bolts, flange repair kits and leak test dye.

How much water can you save with a low-flow toilet and a fixed faucet?
A WaterSense-labeled toilet uses 1.28 gallons per flush or less, which is much less than many older toilets. Fixing a dripping faucet or running toilet stops water from going down the drain all day. Together, these small fixes lower water use and help protect floors and cabinets from damage.
- Lower water use. Less wasted water from leaks and old, high-flow toilets.
- A quieter home. No more hissing tank or drip in the night.
- Protected floors and cabinets. A sealed toilet base and dry sink cabinet prevent rot and mold.
- Better flushing. Modern low-flow toilets are designed to clear the bowl in one flush.
- Possible rebates. Water agencies in the region sometimes offer rebates for water-saving fixtures. Check with your water district for what is available now.

Why is my garbage disposal humming but not working?
A humming disposal is usually jammed, so the motor gets power but the plate cannot turn. A fruit pit, a utensil or built-up food is often the cause. Freeing the jam and pressing the reset button often fixes it. If the motor stays dead, the unit needs to be replaced. Here is how a typical call goes.
Typical job (an example of how these calls go, not a specific customer):
- The problem: a homeowner's garbage disposal hums when switched on, but nothing spins, and the sink is backing up with water.
- The check: the tech turns off the power and looks inside with a flashlight.
- The cause: a small glass bottle cap is wedged between the grinding plate and the ring.
- The fix: the cap is removed, the plate is turned free with a hex key from below, and the reset button is pressed.
- The test: the disposal runs smoothly, the sink drains and the connections are checked for leaks.
- The result: a working disposal in one visit, plus simple tips on what not to put down it.

Should I repair or replace my toilet?
Repair it when the problem is a part inside the tank, like the flapper or fill valve. Replace it when the bowl or tank is cracked, the toilet clogs often or it is very old and uses a lot of water per flush. We will tell you honestly which makes more sense.
How long does a toilet installation take?
Most toilet installs take a few hours. It can take longer if the closet flange needs repair or the floor under the toilet is damaged.
Can a plumber install a faucet I bought?
Yes. We install faucets, toilets and disposals that you bought. Tell us the model when you call, and we will check that it fits your sink before we come.
Can I put bones in a garbage disposal?
No. Bones, fruit pits, grease, coffee grounds and stringy foods like celery can jam a disposal or clog the drain. Run cold water while it grinds, and feed food in slowly.
Why is my toilet leaking at the base?
The most common cause is a failed wax ring under the toilet. A loose toilet or a broken closet flange can also cause it. Fix it soon, because the water can damage the floor below.
Why does my faucet keep dripping?
A dripping faucet usually has a worn cartridge, washer or O-ring inside. Hard water scale can wear these parts faster. Replacing the worn part usually stops the drip.
How do I fix a running toilet myself?
Check that the chain has a little slack and the flapper sits flat. Lower the float if water spills into the overflow tube. If the flapper is warped or the fill valve keeps hissing, replace the part or call us.
Do you fix outdoor faucets and hose bibs?
Yes. We repair and replace leaking hose bibs and outdoor faucets, and we can add an anti-siphon hose bib that keeps garden water from flowing back into your home's water.
