Slow drains everywhere: repair options

Slow drains everywhere mean the main line, not the fixture. Repair options run from a $300 to $800 clear, to a $1,500 to $5,000 spot repair, $4,000 to $12,000 for lining, or $5,000 to $15,000 for replacement. Which one you need is decided by a camera inspection at $200 to $500, because the symptom is identical across causes that cost ten times different amounts to fix.

Why the location of the symptom matters

A single slow sink is a local problem: hair in the trap, grease in the branch, a blocked pop-up.

Slow drains everywhere is a different diagnosis. The fixtures share a building drain that runs to a lateral and then to the municipal main. If several fixtures on different floors drain slowly at the same time, the obstruction is downstream of all of them.

That reasoning costs nothing and eliminates most of the wrong purchases. There is no point snaking a bathroom sink when the kitchen sink, the tub and the laundry all drain slowly.

Two exceptions worth checking first:

• A blocked vent. If the vent stack is obstructed, drains gurgle and run slowly because air cannot enter behind the water. It looks like a blockage and is not.
• A single branch serving several fixtures. Two bathroom fixtures on the same branch can both be slow from one local clog.

Everything else points to the main.

The repair options, by cause

That table is the whole decision tree. Everything below explains how to get to the right row.

Why cleaning is the first step, not the answer

The cheapest option — a clear at $300 to $800 — is the correct purchase when the camera shows soft material in a sound pipe. It is the wrong purchase when the camera shows a defect, because the defect remains.

A useful rule: cleaning buys information if you inspect afterwards. Cleaning without inspection buys a few months.

The pattern that reveals the mistake is repetition. Two clears at $550 is $1,100, which is two-thirds of a spot repair that would end the problem. Three clears at $550 is $1,650, more than a spot repair at the low end.

There is also the damage cost. A belly that holds solids keeps holding them. A joint that admits roots keeps admitting them, and widens. Cleaning resets the clock; it does not stop it.

What a camera inspection adds

At $200 to $500, the inspection is the item that turns a symptom into a scope.

Ask for:

• The footage of the obstruction. Not “about 40 feet” — a number you can check against the recording.
• The condition of the pipe at that footage. Sound, cracked, displaced, collapsed or sagged.
• Whether water is standing. Standing water upstream of a point means the pipe has lost fall.
• A recording you keep. A file with footage marks lets a second contractor quote the same job.

Without those four, the quotes you receive are guesses dressed as prices, and they cannot be compared.

The arithmetic of three quotes

Take a 65-foot clay lateral with roots at two joints and a belly at 40 feet.

• Quote one: clear and cut, $650. Restores flow. The belly remains and will hold solids again.
• Quote two: two spot repairs and a re-lay, $6,800. Fixes all three points, three restorations, two warranties.
• Quote three: burst replacement, $11,500. New pipe, correct grade, one warranty.

Quote two is often the right answer when the defects are local. Quote three wins when the run has more than three problems, or when the belly is severe enough that the spot re-lay cannot restore fall across the length.

The method comparison is in trenchless lining vs spot repair, and the pricing detail is in slow drains everywhere cost.

What not to do

Do not pour chemical cleaner into a main-line blockage. Caustic products sit in the pipe, can damage older fittings, and leave a hazardous residue for the next person who opens the cleanout.

Do not keep plunging a fixture that backs up when another drains. The pressure goes into the branch, not the blockage.

Do not accept a verbal diagnosis. “It’s roots” without a camera is a guess, and it is a guess that costs $1,500 to $5,000 if you act on it.

Do not book a lining job on the same visit as the cleaning. The cleaning is legitimate. The lining decision needs the camera finding and a second quote.

What to do next

1. Confirm the pattern — two or more fixtures, ideally on different floors.
2. Check the vent if the drains gurgle rather than merely run slow.
3. Book a clear at $300 to $800 to restore flow, or a camera first if flow is adequate.
4. Get the camera recording and the footage of the obstruction.
5. Quote two methods on that footage, including restoration.
6. Fix the cause if the camera shows a defect, rather than scheduling another clear.
