Is there a simple way to check the flapper?

Yes. Color the tank water with a little food dye, then leave the toilet unused for about half an hour. Dye in the bowl afterward means water is sneaking past the flapper, and it probably does so all day. A replacement flapper is a small job, and every other toilet in the house is worth the same test.

Should a toilet that rocks be fixed?

Yes. The rocking keeps loosening the wax seal, and when the seal finally gives, waste water escapes with every flush. On a slab it spreads under the flooring; in an upstairs condo it soaks toward the ceiling of the unit below. Get the toilet pulled, the flange checked and repaired, and the bowl reset on a new ring before the damage grows.

When is an old toilet better replaced than repaired?

Start with the porcelain. Without cracks, a toilet can nearly always be restored with new tank parts and a new seal. Replacement is the answer for cracked china, for clogs every week or flushes that always need a second try, and for anyone who needs a higher seat.

Is one visit usually enough for a toilet repair?

Usually. Wax rings, flappers, fill valves, bolts and shutoff stops come along on every call. A cracked flange set in concrete, a damaged drain under the floor or an unusual tank may take longer or need ordering. You hear about any of that before work begins, and nothing is lifted until you have approved the written price.

Toilet Repair and Installation in the San Fernando Valley

Toilet repair and replacement in the San Fernando Valley

Toilets in houses, condos and apartments all over the Valley are part of this service, from Canoga Park, Winnetka and Chatsworth to Northridge and North Hollywood, and out to Calabasas, Agoura Hills, Westlake Village, Hidden Hills, Malibu and Santa Clarita. Only a short list of parts wears out. Inside the tank it is the flapper and the fill valve. Beneath the bowl it is the wax seal, the flange and the two bolts that hold it down. At the wall it is the shutoff stop. The plumber brings most of them to every call, so a typical repair is done on the first visit once you have approved the written price.

Ranch houses went up in the Valley by the thousands after World War II, and a statewide study of tract homes from that era found they were often built on concrete slabs. On a slab, the flange sits in the floor over a drain cast into the concrete, and when the wax ring fails, water spreads under the flooring around the base instead of dripping into a crawl space. Vinyl lifts, grout darkens, and the closet bolts lose their bite in a flange that has cracked or rusted. Once the bowl rocks, every movement breaks the seal a little more. Doing it right means lifting the toilet, scraping away the old wax, checking that the flange is whole, fastened and at the right height, repairing or replacing it, and setting the bowl on a new ring with new bolts. Shims under the base hide the rocking and leave the cause in place. In the oldest houses, such as the Owensmouth homes of Canoga Park built from 1913 to 1939, the drain under the toilet can be an older material, and its condition gets checked before the bowl goes back down.

Condos and apartments add a neighbor to every leak. A failed seal upstairs often shows first as a brown ring on the ceiling below, so before any drywall is opened the plumber pins down which unit and which fixture is at fault, and keeps the manager or association informed. The water itself causes slower trouble. LADWP's Valley sources run from about 6 to 8.2 grains per gallon of hardness and Las Virgenes water averages 8.3, enough to coat fill valve seals, clog the rim holes that rinse the bowl, and freeze old multi-turn stops in place until they crack or leak at the stem the day someone needs them. Both suppliers disinfect with chloramines, which LADWP says slowly break down the rubber inside flexible hoses, so an old supply connector is worth swapping while the toilet is off. A new quarter-turn valve and braided supply line get their own entry on the written price. If a fill valve gives out again shortly after it was replaced, suspect the pressure: LADWP calls for a regulator where static pressure tops 80 psi, and we put a gauge on it. Cracked porcelain is replaced rather than patched. For a new toilet, the plumber measures the rough-in, sets the flange flush with the finished floor, and seats the bowl on a new wax ring with fresh closet bolts.

Common findings under the bowl and in the tank

A flapper gone stiff or warped, letting water slip into the bowl day and night
A fill valve adjusted so high that water pours into the overflow tube
Scale on the fill valve seal or packed into the rim holes
A flange that is cracked, rusted or sitting below the finished floor
A wax ring squashed flat by a bowl that has been rocking
A shutoff stop that will not turn, or that drips at the stem

Signs it is time to call

The tank refills on its own in the night when no one has flushed
The seat shifts or tips when someone sits down
Flooring around the base that is soft, stained or lifting
A brown stain growing on the ceiling under a bathroom
It takes a second flush to clear the bowl, or the flush has no push
A sewer smell close to the base of the toilet

Repair it or replace it

A toilet that seems worn out usually is not. The flapper, fill valve and seals are wear parts, meant to be swapped, and with fresh ones a sound bowl and tank can serve for decades. Replacement earns its place when the porcelain has cracked, when clogs come weekly, or when someone in the home needs a taller seat. Water is the other reason. California expects homes built on or before January 1, 1994 to have water-saving fixtures, meaning toilets that use no more than 1.6 gallons per flush, and much of the Valley's housing predates that by decades. Before you buy, look at the regional Water$mart rebate program and, inside the city, LADWP's residential rebate programs, since toilets are on their lists and the terms change.

When new parts will do the job, new parts are what you are quoted. A replacement shows up on the written price only when the fixture itself has failed.

When the problem is past the toilet

Sometimes the toilet is only the messenger. Several slow drains at once, gurgling in the bowl when the washing machine drains, or a plunger that only sends water surging back up: all of these point farther down the line, to the drain under the house or the lateral to the street. Inside the city, the owner is responsible for the lateral from the property line to the main, roots under the street included, and LA Sanitation looks after the main itself. The City's engineers put it simply: if yours is the only house on the block with a sewer problem, the problem is in your lateral. In Calabasas, Agoura Hills, Westlake Village, Hidden Hills and Santa Clarita, the owner's share also runs all the way to the main. In Malibu most homes drain to a septic tank instead, and a toilet that backs up can be the first sign the system needs attention. Drain cleaning and sewer repair each have a page of their own for the camera and cleaning side.

The silent leak and the dye test

The leak that wastes the most water is often the one nobody hears. A flapper that no longer seals lets water trickle into the bowl, and now and then the fill valve kicks on to refill the tank. No puddle forms and nothing overflows, so the first clue is usually a bill from LADWP, Las Virgenes or SCV Water that rose without explanation. Across a building with many units, a single running toilet can go unnoticed for months.

The test takes a few drops of food coloring. Add them to the tank, hold off flushing for about half an hour, and then check the bowl: tinted water there points to a flapper that leaks. Test every toilet in the house while the bottle is out. A leak at the base is worse, especially over a downstairs unit or a finished floor, and it deserves a call whatever the hour.
