There’s a distinct kind of panic that sets in when every sink, tub, and toilet in your house starts acting up at the same time: water backs up, toilets gurgle, the laundry won’t drain, and a smell of sewage may be present. When multiple fixtures fail simultaneously, it’s usually a single underlying problem — and acting quickly and correctly can prevent more damage and a bigger repair bill. This guide walks you through what to do immediately, how to diagnose the likely causes, safe DIY checks you can run, when to call a professional, how technicians fix the issue, and how to prevent a repeat. If you’re looking for a reliable Plumbing Company In Commerce City CO to respond fast, this article will help you prepare for the conversation and choose the right service.

First things to do immediately (safety and damage control)

  1. Stop using water. Don’t run faucets, flush toilets, or start the dishwasher or washing machine. Every drop you add increases the chance of a sewage backup into the house.

  2. Turn off appliances that use water. Shut off your washing machine and dishwasher at the breaker or appliance switch if possible.

  3. Protect your home. Move towels, rugs, and valuables away from areas with standing water. Use buckets to catch small leaks if necessary.

  4. Avoid chemical drain cleaners. These are usually ineffective against mainline blockages and can create hazardous conditions for you and for the professionals who must later work on the pipes.

  5. Take photos. Documenting what you see — standing water, backup locations, and affected appliances — is useful for technicians and for potential insurance claims.

If sewage is rising into living spaces and you can’t stop the inflow, shut off the main water and call for emergency help. Don’t try to pry open sewer cleanouts or access points if you’re unsure — that can make the mess worse.

How to tell whether it’s a main sewer problem (not separate clogs)

When multiple drains back up at once, the main sewer line or a shared branch line is the most likely culprit. Look for these signs:

  • Multiple fixtures are affected (toilet, tub, kitchen sink) at the same time.

  • Flush one toilet and watch other drains — if water moves or gurgles elsewhere, that’s a mainline symptom.

  • Sewage smell coming from floor drains or the yard near your sewer cleanout.

  • Slow drains throughout the house rather than a single slow sink.

If only one fixture is slow, it’s usually a localized clog. If the top and bottom fixtures both show problems, think mainline.

Safe DIY checks you can try (limitations and warnings)

Be conservative with DIY attempts. The mainline can be messy and dangerous.

  • Locate the sewer cleanout. This is usually a capped pipe near the foundation, garage, or yard. If the cap is loose and sewage is visible, don’t open it — call a pro. If you know how to safely access it and there’s only standing water, you might be able to remove the cap to relieve pressure, but only if you’re comfortable and wearing protective gear.

  • Use a plunger on individual fixtures. A good flange plunger on the toilet or a cup plunger on a sink can help where the clog is nearby, but plungers rarely fix mainline or heavy grease/root blockages.

  • Try a sink auger for localized clogs. A handheld snake can clear a clogged sink trap or toilet in many cases — but avoid heavy snaking on main sewer lines without the proper equipment.

  • Don’t use chemical drain cleaners. They don’t fix major blockages and can corrode pipes or make repairs harder.

  • If you have a wet/dry vacuum and know how to use it safely, it can remove standing water from a toilet or floor drain, but it won’t clear the underlying cause.

If your DIY efforts don’t yield clear results in 15–30 minutes, stop and call a professional. Prolonged DIY attempts can make a problem worse or contaminate your home.

When to call a professional (and what to expect)

Call a licensed Plumbing Company In Commerce City CO — for example, Fast Trak Plumbing And Drain — when you see any of these red flags:

  • Sewage entering living areas.

  • Multiple fixtures clogged at once.

  • Uncertainty about the source of the problem.

  • Recurring backups even after DIY attempts.

  • Visible sewage near the cleanout.

What a professional will typically do on arrival:

  1. Ask targeted questions about the symptoms and any recent incidents (tree planting, heavy rains, construction).

  2. Do a camera inspection. This small video camera is sent into your sewer to locate the blockage and assess pipe condition. Camera work is the single most important diagnostic step.

  3. Recommend a solution. Based on camera findings, the tech might perform a hydro jetting clean, use a power auger root cutter, or advise a repair or replacement if pipes are failed.

  4. Execute the repair or cleaning. Hydro jetting (high-pressure water cleaning) often resolves grease, scale, and root intrusions. If the pipe is broken or collapsed, the crew will provide options like trench repair or trenchless lining.

  5. Verify results. Professionals typically re-run the camera to prove the line is clear and show you before/after footage.

Expect honest technicians to explain the cause, show the camera footage, and give a written estimate before major repairs.

Typical causes of whole-house drain failure

  • Mainline blockages from tree roots. Roots find joints, invade, and cause severe blockages.

  • Grease buildup from kitchen drains that accumulates and narrows the mainline over time.

  • Flushing wipes or non-flushable items that catch and trap solids in a downstream pinch point.

  • Pipe collapse, severe corrosion, or offset joints, which create a constant failure that shows up as multiple backups.

  • Municipal sewer line clogs, backups, or city work that temporarily affects neighboring houses.

Example case study (anonymized, real-world-style)

A family in Commerce City experienced every drain slowing over two days and a faint sewage odor in the yard. They called Fast Trak Plumbing And Drain. Technicians arrived within hours, did a camera inspection, and found a large root mass and heavy grease buildup at a junction in the mainline shared by two properties. The crew used a combination of root-cutting nozzles and hydro jetting to clear the obstruction, then performed a final camera pass to confirm full flow. The technicians also recommended installing a backwater valve and scheduling annual hydro jetting to prevent recurrence. The immediate cost was higher than a snake job, but the homeowner avoided repeated emergency calls and the nearby neighbors benefited from the shared-line cleanup. The result: no backups in the following 18 months and clear documentation for the homeowner.

Preventing future simultaneous clogs

  • Schedule periodic maintenance. Annual or biennial hydro jetting and camera checks will clear grease and small root growth before they become emergencies.

  • Watch what you flush. Avoid wipes, feminine hygiene products, and other non-flushables.

  • Manage grease safely. Don’t pour cooking oil down the sink; use a can for solidified grease disposal.

  • Install hair and food traps where appropriate. Kitchen strainers and shower hair traps catch solids before they reach the line.

  • Control trees and large roots. If roots invade repeatedly, consider targeted root barriers or replacing the affected pipe segment.

  • Consider a backwater valve (backflow preventer) if your house is at risk for sewer backups during heavy storms or municipal surcharges.

A local, trusted Plumbing Company In Commerce City CO can set a maintenance schedule and recommend which preventive measures make sense for your property.

What to tell your plumber when they arrive

  • When the problem started and any recent changes (new trees, heavy rains, remodel).

  • Which fixtures are affected and whether any appliances are shut down.

  • Whether you have a septic system or are on city sewer.

  • Access to the cleanout and where it is located (if you know).

  • Any prior plumbing repairs or recurring issues.

Providing this information helps the technician diagnose faster and gives you a clearer estimate.

Choosing the right service provider

Look for these qualities: licensed and insured technicians, prompt emergency response, camera inspection capability, hydro jetting equipment, clear written estimates, and local customer reviews. A well-experienced, results-driven company will show before-and-after camera footage, offer honest repair options, and explain maintenance plans.

FAQs

Some homeowner policies include limited sewer backup coverage; check your policy or contact your agent. Take pictures and keep invoices for any claim.

How much will repairs cost?
Costs vary by cause and solution. A service call and camera inspection are a good starting investment; major repairs like pipe replacement are more expensive. Preventive maintenance often saves money long-term.
