Plumbing Help for Whittier Homeowners
Ten ZIP codes, one dispatch line, about 11.5 miles from Arcadia: describe the problem and a plumber is assigned.

When you call from Whittier, the dispatch line answers, asks about the problem and your street, and assigns a plumber for your address. Whittier is about 11.5 miles from Arcadia, so the dispatcher will tell you honestly what the timing looks like. Whittier has ten ZIP codes, listed below, and all of them are on the network.
The rest of this page follows the order of a typical visit: urgent problems, drains and sewer lines, leaks and fixtures, water heaters, the shorter jobs, then two local facts, the City’s water hardness and the age of the housing stock, and finally the neighborhoods and landmarks that identify an address, including South Whittier and East Whittier.

Call (626) 687-0217Emergency plumber in Whittier: South Whittier and every ZIP
Call at once for a burst pipe, a sewer backing into a tub or floor drain, a water heater leaking steadily, no water at all or any smell of gas. A 24 hour plumber answers through the dispatch line at night and on weekends, and same-day visits can be booked when the schedule has room. Running water and sewage jump the queue.
Whittier callers searching for an emergency plumber in South Whittier or a 24 hour plumber in Whittier reach the same line. Close the main valve for a leak, leave drains alone during a backup and walk outside before phoning SoCalGas at 1-800-427-2200 if gas is the problem. Night and weekend handling is explained on the main Arcadia page.
Drain cleaning in Whittier: from one slow sink to the main line
A single slow drain gets a cable or a trap clean-out. Several fixtures backing up at once point at the main, where hydro jetting scours the pipe wall and a camera can follow. Emergency drain cleaning is the same work done on a night call: stop the water, find the cleanout and let the plumber work from there.

Main sewer line cleaning is not the end of the story if the line keeps clogging, because roots, a sag or a cracked joint will bring the blockage back. The main line clog clearing sets out the methods, and drain pipe repair or replacement is the next step when a camera shows damage. For a restaurant line or shared building drain, see commercial plumbing.
Sewer line repair and replacement in Whittier
A sewer problem is repaired after it is located, not before. A camera shows the crack, offset joint or root mass, and a locator gives the depth. The three usual fixes are spot repair, lining and full replacement, and the sewer repair and replacement compares them. Ask for the recording, the footage distance from the cleanout and the reason the plumber chose that fix.
Sewer pipe repair and sewer line replacement in Whittier involve digging more often than lining does, so utilities must be marked through 811 well before a trench is opened. A plumber should also tell you whether the permit is theirs to pull.
If the camera finds only a root intrusion, cutting the roots and then re-scoping the line a few months later is a reasonable plan. If it finds a collapse, repeated cleaning only delays the replacement.
Leaks, fixtures and repiping in Whittier
Leaks. A bill that rises with nothing new in the house suggests a hidden leak. The meter test and listening gear used in finding a hidden leak narrow it to one area, including leaks under the slab found by thermal and acoustic tools on the slab leak detection.

Faucets and toilets. Faucet repair in Whittier usually means a cartridge or washer, and toilet repair a flapper or fill valve. Toilet installation, shower valves and sinks are on the faucet, toilet and fixture repair.
Repiping. Leaks in more than one place are the usual reason to talk about galvanized pipe replacement. Ask what pipe the house has now, what it would be replaced with and how long the water is off.
Water heaters in Whittier: repair first, replace when it makes sense
For a heater that is cold, loud or leaking at a fitting, the water heater troubleshooting lists what is checked first. A tank leaking through its shell is replaced, and heater installation explains what a replacement visit should include. Tankless is an option where the gas line and wall allow it; see tankless installation. A new tank must be strapped under California Health and Safety Code 19211, so confirm that is included. Gas piping for a heater or range is on the gas line testing.
Smaller jobs are handled too: a disposal replacement that jams, water that has to be dried out (water damage response), a failing water line repair and water softener.
Whittier water: the City’s own supply reports hardness of 250 mg/L
The City of Whittier’s 2024 water quality report says its supply comes from six active deep wells in the Whittier Narrows area, drawing from the Main San Gabriel and Central groundwater basins.
| Item | Figure | Year |
|---|---|---|
| Hardness as CaCO3, reported | 250 mg/L | 2024 |
| Hardness as CaCO3, range | 230 to 270 mg/L | 2024 |
That report covers the City’s own system only. An older City environmental report says Whittier is also served by Suburban Water Systems and San Gabriel Valley Water Company, and we could not read either company’s current report. So one value cannot be given for every Whittier tap. Check the supplier named on your bill. Hardness at this level leaves scale in heaters and on fixtures, which is why the softener and filtration discusses when treatment is worth the cost.
Whittier homes and the pipes that come with them
Whittier is an older city. The median home was built in 1956, and about 88 percent of housing units, 26,309 of 29,734, were built in 1979 or earlier, per the Census Bureau’s 2020 to 2024 estimates.
Whittier’s median year built is 1956. About 88 percent of its housing units, 26,309 of 29,734, date from 1979 or before.
The year says nothing about which pipe a given house has, but it does mean a leak, a failing heater or a recurring clog may involve older lines. Ask the plumber to identify the supply and drain material at the first visit and to explain the repair against the cost of replacement.

Plumbing questions in Whittier
How hard is Whittier water, and should I treat it?
The City of Whittier reported hardness of 250 mg/L as CaCO3, in a range of 230 to 270, in its 2024 water quality report. Because other companies supply parts of the city, your own bill is the better guide. Scale in the heater and on fixtures is the sign that treatment may pay.
How old are Whittier homes, and what pipes do they have?
ACS data for 2020 to 2024 puts the median build year at 1956, with roughly 88 percent of units dating from 1979 or before. No source names the usual pipe here, so have the plumber identify yours and describe its condition.
