Local Toilet Repair in Malibu, CA
Running, leaking, rocking or weak flush. Most toilet fixes are small, and you'll know the price before I start.
Written by Sergio, owner of Malibu Plumbing Pros. Last updated October 2026.
You hear it at night. A hiss, then the tank fills for a few seconds, then quiet. Twenty minutes later, it does it again. Or the handle needs a jiggle, or the bowl rocks a little when you sit. I'm Sergio, and toilet repair in Malibu, CA is some of the most common work I do. Most of it is quick.
I'll tell you what's wrong and what it costs before I touch anything. If it's a part you can swap yourself, I'll say so.
When Toilet Repair May Be the Right Next Step
Sound familiar? These are the calls we get most.
Toilet runs on its own
The tank refills every so often with nobody using it. That's water you pay for, day and night.
Have to jiggle the handle
It won't stop running unless you jiggle the handle or reach in and push the flapper down.
Weak or double flush
It takes two flushes to clear the bowl, or the flush is slow and lazy.
Water around the base
A puddle on the floor or a soft spot by the toilet. Often a failed wax ring under the bowl.
Toilet rocks or wobbles
The bowl moves when you sit. Loose bolts, a broken flange or a floor that isn't level.
Slow or noisy refill
The tank takes forever to fill, or it whistles and hums the whole time.

Same four steps on every toilet repair job.
- STEP 01
Find the real leak
A few drops of food coloring in the tank shows if the flapper leaks. Then I check the fill valve and base.
- STEP 02
Show you the part
I show you the worn part and give you the price first. Small fix, small bill.
- STEP 03
Fix it and test it
New part in, then I flush it a bunch of times and check for drips under the tank and at the floor.
- STEP 04
Clean up after
Old parts gone, floor wiped, and I tell you what to keep an eye on.

When the Wax Ring Fails and the Floor Gets Wet
The hard one is the leak you can't see, and it's the toilet repair in Malibu, CA that takes the most care. The wax ring is a soft seal under the toilet that connects it to the drain pipe. It can fail slowly, a little water every flush, soaking into the subfloor for months. You notice a stain on the ceiling below, or the floor by the toilet feels soft.
When that happens, I pull the toilet, scrape off the old wax, and look at the flange, the ring bolted to the floor that holds the toilet down. On a lot of older homes, the metal part of that flange is rusted thin. I repair or replace it, set a new seal, and bolt the toilet down level. If the subfloor is rotten, I'll show you before anything else happens. And if the drain line itself is backing up, that's a different job, and our drain cleaning page covers it.
Why Your Toilet Keeps Running
Most of the time, a running toilet comes down to one of two parts. The flapper is the rubber seal at the bottom of the tank. When it wears out, water leaks into the bowl and the tank keeps refilling to make up for it. The fill valve is the tower on one side of the tank that refills it. When it sticks, water spills into the overflow tube and never stops.
The EPA's WaterSense program has an easy test. Put a few drops of food coloring in the tank. If color shows up in the bowl within 10 minutes, you have a leak. The EPA also says to check flappers and swap them at least every five years. The average home's leaks waste more than 9,300 gallons a year, and worn flappers are one of the usual suspects.
Can You Fix It Yourself?
Often, yes. A flapper is a cheap part at any hardware store. Turn off the small valve behind the toilet, flush to empty the tank, unhook the old flapper and clip on the new one. Take the old one to the store with you (trust me, it saves a second trip). There's two common sizes, 2-inch and 3-inch, and the wrong one won't seal.
A fill valve is a bit harder but still a DIY job for a lot of people. Where I'd call a pro: water on the floor, a crack in the tank or bowl, a toilet that rocks, or a shutoff valve that won't turn. On older houses those little valves can snap when you force them, and then you've got a real problem.
California's Low-Flow Toilet Rules
If your home was built before 1994, here's something to know. California law says pre-1994 single-family homes need water-saving fixtures, and when you sell, you have to tell the buyer about any that don't comply. A toilet made to use more than 1.6 gallons per flush counts as non-compliant.
Since January 1, 2014, toilets sold in California can't use more than 1.28 gallons per flush, under a state law called AB 715. The EPA says toilets are nearly 30 percent of the water used inside a home, and old ones can use as much as 6 gallons a flush. Switching to a WaterSense model can save a family nearly 13,000 gallons a year.
People worry low-flow means a weak flush. Today's models are a lot better than the early ones. I'll help you pick one that clears the bowl the first time.
Toilet Repair in Malibu, CA: How Long It Takes
A flapper or fill valve swap usually takes me under an hour. Pulling a toilet to replace the wax ring takes an hour or two, more if the flange needs work. A full toilet swap usually takes a couple of hours, including hauling the old one away.
If you're on a septic system, don't wait on a running toilet. The City of Malibu says septic systems handle the majority of the city's wastewater, and the EPA warns that a lot of extra water can push solids out of the tank and into the leach field, where they clog things up. A toilet running all night is a lot of extra water.
What If It Starts Leaking Again?
If something I fixed isn't right, I come back and make it right. That's Sergio's Done-Right Guarantee. Parts wear out over time, so I'll tell you how old the rest of your toilet's insides look, and you can decide if you want to swap them while I'm there.
What to Expect
Time: Under an hour for most running-toilet fixes. One to two hours for a wax ring or a new toilet.
Mess: I put a towel and drop cloth down, sponge out the tank and bowl before I lift anything, and wipe the floor when I'm done. You'll only be without that one toilet while I work.
Permits: Swapping parts or a toilet like-for-like usually doesn't need one. If your job does, I tell you before we start.
Cost: Angi's national toilet repair numbers put the average at $271, with most jobs $150 to $391. A running toilet runs $100 to $400, a wax ring $50 to $200, and a full toilet replacement $90 to $1,500. Those are national numbers. For toilet repair in Malibu, CA, I give you my price before I start.

Why does my toilet run by itself every few minutes?
Almost always a worn flapper letting water slip into the bowl, so the tank refills to catch up. Try the EPA's food coloring test: a few drops in the tank, wait 10 minutes, and check the bowl. If color shows up, the flapper is leaking. It's a cheap part and often an easy DIY fix.
Should I repair or replace my toilet?
Repair it if the bowl and tank are sound and it flushes well. Replace it if it's cracked, rocks after a new wax ring, or was made before 1994 and uses more than 1.6 gallons a flush. A new 1.28-gallon toilet uses a lot less water. I'll give you both prices so you can choose.
Do I have to replace my old toilet by law in California?
For pre-1994 single-family homes, state law says water-saving fixtures should be installed, and sellers must tell buyers about any non-compliant ones. A toilet made to use over 1.6 gallons per flush counts. Check with your real estate agent if you're selling, and I can swap the toilet if it's needed.
How do I know if the wax ring is leaking?
Look for water at the base after you flush, a sewer smell in the bathroom, a soft floor next to the toilet, or a stain on the ceiling below. If the toilet rocks, the seal may already be broken. It's worth fixing soon, because the water usually goes into the subfloor where you can't see it.
Can you install a toilet I bought myself?
Yes, as long as it's new and has all its parts. Before you buy, measure from the wall to the bolts on the floor. Most are 12 inches, but some homes have 10 or 14. If it doesn't match, it won't fit right. Send me the model and I'll double-check it for you.
