Camera inspection on recurring backups is standard. You'll see what we see.
Clogged drain? What we clear and how
A clogged drain shows up in a few predictable ways, and where it's clogged tells us how to clear it. A kitchen sink with water sitting in the basin is almost always grease and food scale packed in the trap arm or the branch line past the trap, so we pull the trap and run a 25-foot cable or small jetter down the branch to clear the pipe wall, not just a hole through the middle. A shower or tub that drains slow and then backs up is hair bound with soap scum at the strainer or the first few feet of drain, and a hand snake with a strainer clean-out handles most of those in one visit. A bathroom sink that clears when you pull the P-trap but backs up again within a week has its blockage downstream in the branch line, which needs a cable rather than a plunger.
One slow fixture or the whole house? The tell that matters most
The tell that matters most: one slow fixture is usually a local clog, but two or more backing up together, or a toilet that bubbles when the washer drains, means the main line is involved and a plunger will only push the problem around. We diagnose where the clog actually is before we pick a machine, quote it in writing, and clear it. A backed-up kitchen or a shower you can't use is an active problem, not a wait-and-see one.
Clogged drain plumber: four signs it's time to call one
A clogged drain plumber earns the call the moment a store-bought snake or a bottle of drain cleaner stops working, and there are four clear signs you're there. One, you've snaked the same drain more than once and it keeps coming back. Two, more than one fixture is backing up at the same time, or a toilet gurgles when the washer or tub drains, which means the clog is in the main line and not a single fixture. Three, there's a sewage smell or water coming up in the lowest drain in the house. Four, the clog is deep in the pipe past where a 25-foot hand snake reaches, so you can feel the cable stop against something solid and nothing you do clears it. When a drain is clogged deep in the pipe like that, the blockage is usually in the branch line inside the wall or out in the main, and it needs a powered cable or a jetter sized to the line, not a hardware-store auger.
DIY fix or service call: how we draw the line
That's the honest line between a DIY fix and a service call: if it's one slow fixture you can reach, try the plunger and the trap first. If it's any of those four signs, a plunger only pushes the problem around, and you want a licensed plumber who diagnoses where the clog actually is before picking a machine. We quote every clogged drain service in writing before we open the line, run small-line cable on sinks and tubs and full-size equipment on mains, and tell you straight whether it's a one-time clear or a recurring problem that needs more than snaking. Call 213-254-8695 and we'll tell you which it is.
Why does my drain keep clogging?
If you're clearing the same drain every few months, the clog isn't the problem, it's the symptom. When a clog comes back on a schedule, we stop snaking and put a camera in the line, because clearing the same drain four times a year is money spent on the wrong fix. The usual causes we find are grease and soap scale that a cable only cut a hole through so it reglazed and closed back up, root intrusion at a joint or crack in the main, a low spot or belly in the line that holds water and solids, or old galvanized and cast iron scaled down to a fraction of its bore. Norwalk's hard water, running roughly 8 to 15 grains per gallon depending on the block, speeds up scale buildup in older lines, so drains in pre-1990 homes here tend to reclog faster than newer plumbing. Hydro-jetting scours the pipe wall clean instead of punching through, which is why a recurring grease or scale clog often needs jetting to actually stay clear.
Drain cleaning — the right tool for the line
Sinks and tubs get a 25-foot mini-snake or 1/4" inner-core cable so we don't beat up the trap arm or P-trap. Branch lines get a 50 to 75 foot sectional with the cutter head matched to the obstruction. Main sewer lines get a 100-foot drum machine or a hydro-jetter for grease, soap, and root mat. One-size-fits-all flat-rate shops will run a main-line machine through your kitchen drain and break the trap. We won't.
Sewer camera inspections
When a clog comes back within 90 days, the answer isn't to keep snaking it — there's a root intrusion, a belly, a broken hub, or a misaligned joint somewhere in the line. We push a self-leveling color camera through the drain, locate the defect with a 512Hz sonde, and show you the footage. You decide whether to spot-repair, line, or replace.
Digital video & locating
We record the inspection (USB or emailed link) and provide a depth-and-position locate for any defects — accurate to within a few inches. If you're getting estimates from excavation contractors, that locate saves them guesswork and saves you money on the dig.
When snaking isn't enough: hydro-jetting & main-line clearing
Cable machines cut a hole through a clog. For a one-time blockage that's all you need, and that's most of what a drain cleaning call is. But when the clog is grease packed against the pipe wall, hard scale in old galvanized, or a root mat in the main, a snake only bores a channel through it and the line reglazes and closes back up on a schedule. That's when snaking isn't enough and the right tool is a hydro-jetter, which scours the full bore of the pipe clean with high-pressure water, with a camera run before and after so you can see the pipe wall go from coated to clean. Recurring and main-line clogs are their own job, so we cover hydro-jetting, main line clog clearing, and sewer camera inspection in detail on the hydro-jetting and main line clearing page. If your clog is a single stopped sink, you don't need any of that, and we'll say so. See the hydro-jetting and main line clearing page for how we handle drains that keep coming back.

Frequently asked questions
When should I call a clogged drain plumber instead of snaking it myself?
Call a plumber when any of these is true: you've snaked the same drain more than once and it keeps coming back, more than one fixture backs up at the same time, a toilet gurgles when the washer or tub drains, there's a sewage smell, or the clog is deep in the pipe past where a 25-foot hand snake reaches. Those all point to a branch-line or main-line clog that a store-bought auger can't clear, and a plunger only pushes it around. If it's one slow fixture you can reach, try the plunger and pulling the P-trap first. We'll tell you honestly which one you're dealing with before you pay for a service call.
How much does a clogged drain service cost?
We price every clogged drain service by scope and quote it in writing before we open the line, not by a flat fee or by the hour. A straightforward sink or tub clear is a smaller job than a main-line clog that needs a full-size machine or a jetter, so the number depends on where the clog is and what it's made of, which we diagnose on-site first. There's no money down on a standard drain call. Call 213-254-8695 for a written quote.
What does it mean when a clog is deep in the pipe?
A clog deep in the pipe sits past the trap and the first few feet of drain, usually in the branch line inside the wall or out in the main. The tell is that a hand snake runs out of reach and stops against something solid, or the drain clears briefly when you pull the trap and then backs up again within days. That depth is beyond what a hardware-store auger clears, so it needs a powered cable or a hydro-jetter sized to the line. If it keeps coming back after clearing, the cause is usually roots, a belly, or scale, and that's worth a camera before snaking it again.
Do you handle a clogged sink drain, or just main lines?
Both. If it's a single clogged sink, that's a fixture-level job we clear the same day in most cases, and we cover exactly how we handle P-trap, disposal, and double-basin backups on our clogged sink drain page. This drain cleaning page covers the whole picture, from one slow fixture up to a main-line clog that backs up the whole house. We size the equipment to the line either way and quote it in writing first.
Why does my kitchen sink stay clogged past the trap?
If pulling or clearing the P-trap gets the water moving but it backs up again within a week or two, the blockage is downstream of the trap, in the branch line inside the wall. That's grease and food scale packed against the pipe wall where a plunger can't reach it. We run a cable or small jetter into the branch line to clear the full bore, not just the trap. On older Norwalk homes with galvanized branch lines that have scaled down, jetting is often the only thing that gets the drain back to full flow.
Why does my drain keep clogging?
A drain that reclogs on a schedule is a symptom, not a one-off. The common causes are grease or soap scale that a cable only cut a hole through (so it reglazed and closed back up), root intrusion at a joint in the main line, a low spot in the pipe that holds solids, or old scaled-down galvanized and cast iron. Norwalk's hard water speeds up scale buildup, so drains in older homes here tend to reclog faster. When it comes back repeatedly, we camera the line to find the real cause and jet it clean instead of snaking it again.
Why does my main sewer line keep clogging?
Recurring main sewer line clogs are almost always root intrusion (at a hub or crack), a low spot ("belly") that holds water and solids, or scale buildup in old cast iron. A camera inspection identifies which, and lets us recommend the right fix instead of guessing.
Do you do hydro-jetting?
Yes. Hydro-jetting is the right tool for grease, soap, hair, and root mat — wherever cable cleaning just cuts a hole through the blockage instead of cleaning the pipe wall.
Will snaking break my old cast iron drain?
Not if you size the machine correctly to the line. We never run a 3/4" main-line cable through a 1-1/2" sink drain. Older cast iron deserves the right tool, not the biggest one in the truck.
Are you licensed, bonded and insured?
Yes. Nava's Elite Plumbing carries a current California master plumber registration, $1M general liability coverage, and workers' comp on every technician. A certificate of insurance naming you or your property manager is available on request before we start.
Do you give upfront pricing?
Every job is quoted in writing before any work begins. We price by scope, not by the hour, so the number you approve is the number you pay — barring scope changes you approve in writing.
Do you require money down?
No deposit on standard service calls. On larger projects (repipes, sewer replacements, gas line installs) we phase work into progress payments tied to city inspection milestones — you never pay ahead of completed work.
