Is Any Plumber Open Right Now in San Clemente?
Yes. Hummel Plumbing answers 24 hours a day, 7 days a week, including holidays, and San Clemente is a short drive down the 5 from our shop in San Juan Capistrano. For a toilet that will not stop overflowing, close the valve behind the toilet first so it stops refilling, then call (949) 505-9828.
Stop an Overflowing Toilet Right Now
- 1Close the supply valve behind the toilet. It is the small handle on the wall or floor near the base. Turn it clockwise until it stops and the tank stops refilling.
- 2If the valve is stuck, lift the tank lid and raise the float, or press the flapper down, so no more water drops into the bowl.
- 3Do not flush again. Anything you add has nowhere to go.
- 4Check the other drains. If the tub or shower is backing up too, or the toilet gurgles when you run a sink, the problem is probably the main sewer line, so stop using water everywhere in the house.
- 5Keep people and pets out of the room, and move rugs and anything absorbent off the wet floor.
Is It the Toilet or the Main Line?
An overflowing toilet is either a clog in that toilet or a blockage further down the line that the toilet happens to reveal. Toilets are often the lowest opening in the house, so when the main line backs up, that is where the water shows first.
The difference changes the fix. A single clogged toilet usually clears with a toilet auger. A main line backup needs the line cleared from a cleanout, and if it has backed up before, a camera inspection to see why. Several slow drains at once, gurgling, or sewage odors all point at the main.
What a Late Night Call Looks Like
You call, the phone is answered, and you tell us what is happening and what you have already shut off. We tell you what we can do and give you pricing up front before any work starts.
When the plumber arrives, the goal is to get the water stopped and the line flowing, then to find out whether this was a one time clog or the sign of something that will come back. If it is the main and it has happened before, we will recommend a camera inspection so the next call is a repair and not a repeat.
Why Toilets Overflow
- Too much paper at once, or wipes sold as flushable that do not break down the way paper does
- A partial blockage further down the line that finally closed off
- Roots working into a cracked joint in an older sewer line
- Grease and scale narrowing an aging drain line until it cannot keep up
The first two are one time events. The last two come back until the cause is fixed, and that is what the camera is for.

We've used Jon with Hummel Plumbing a few times now here in San Clemente, and he's been great every single time. He previously installed our tankless water heater, and most recently fixed our outdoor shower and handled a few other items for us. Everything has always been done correctly the first time—no shortcuts. He's friendly, thorough, and clearly takes pride in doing things the right way. He was also able to come out quickly, which we really appreciated. It's honestly such a relief to have a plumber we trust. Highly recommend Jon and Hummel Plumbing!
Jon and his assistant were prompt, courteous, knowledgeable and fast. I will personally recommend Hummel to my friends and neighbors! Excellent company to deal with in today's world!
