Multi-Unit and Two-Family Drain Services in Ohio

What is shared

Fixtures in each unit drain into a stack, usually one per bathroom or kitchen group. Several stacks join in a building drain in the basement, which leaves the building as one lateral. A blockage in the building drain or lateral affects every unit. A blockage in a stack affects units above or below it, depending where it is.

The lowest unit shows it first

Water backs up at the lowest openings. In a two-family house, that is the basement floor drain or the first-floor tub and toilet. A ground-floor tenant is often the first to see a main line backup, even though the cause may be anywhere upstream.

What to tell the dispatcher

• How many units and floors.
• Which units are affected and which are not.
• Whether the basement floor drain shows water.
• Whether laundry is shared and where.
• The age and type of building.
• Any cleanout you know of.

Who calls

A tenant can call, but landlords and managers typically authorize work, and the lease decides who pays. We do not give legal advice about responsibility. Calling quickly protects the property either way.

Shared laundry

Lint is a major cause of shared-line trouble. See laundry drain clog.

How it is cleared

The technician finds the best access, a basement cleanout if available, and clears the building drain with a cable or jetter. They test with water from several units where possible, and a camera shows the cause.

Keep a record

A camera recording documents what was found and when. For a repeat problem, it supports a maintenance schedule. See sewer camera inspection.

Prevention for managers

Tenant guidance on wipes and grease, a regular clearing interval for a line known to have roots, and a note of the cleanout location help. See preventive drain maintenance. None of it guarantees a clear line.

Cost and time

Larger buildings and longer lines cost more. The technician gives you the price before work begins. We do not promise a duration.

Common building types

In Ohio's older cities, two-family houses, doubles and small walk-up apartment buildings are common. A typical double has two units side by side or stacked, with shared stacks, a common basement and one lateral. A small apartment building may have several stacks and a larger building drain.

Newer small buildings, such as townhouse rows and fourplexes, often have separate stacks per unit that join below the slab. The way the lines combine decides who is affected by what.

A stack clog

A stack is the vertical pipe that carries waste from upper floors down. A clog in the stack affects fixtures above it, and sometimes causes water to appear in a fixture below it that is connected at a lower point. Tenants in an upstairs unit may see slow drains, while a ground-floor unit sees none, or the reverse.

Telling the dispatcher which units are affected and which fixtures lets the technician decide whether to start at the roof vent, at a cleanout on the stack, or at the building drain.

The basement as the hub

Everything meets in the basement. The building drain, the cleanouts, and often the laundry and a floor drain are there. A building with a shared laundry has the lint problem in one place. A building with a boiler or utility room may have a floor drain tied to the same line. A basement unit is the first to flood.

If tenants have access to the basement, ask them to avoid using water and to keep the area clear for the technician.

Notifying tenants

When a main line is being cleared, water in upper units may be affected for a short time. Letting tenants know, and asking them to hold off on laundry, showers and flushing while the technician works, avoids new overflows during the visit. A short notice taped to doors works.

Repeat problems in a building

A building that has had two or three backups in a few years has a pattern. Roots, a low spot, scale in an old cast iron building drain or a shared laundry may be involved. A camera recording is the best way to find out. A landlord with that recording can decide on maintenance, or on a larger project, from facts.

See tree roots and cast iron drains for two common causes.

Insurance and records

We do not give insurance or legal advice. Keeping a record of what happened, when it was reported, who came and what was found, is useful in every case. The camera recording and the technician's notes are part of that record.

A landlord's checklist before the call

Which units are affected? Is the basement floor drain wet? Is laundry shared? Where is the cleanout? Who has keys to each unit? Is a tenant home? Having keys and contacts ready saves time, because a technician may need access to several units to test.

A tenant's checklist

Stop using water. Tell your landlord or manager at once. Keep a record of the time and what you saw. Move belongings off the floor. If you are told to call yourself, tell the dispatcher it is a shared building.

Who pays

That depends on the lease and on what caused the backup. We do not give legal advice, and the technician quotes the price to whoever authorizes the work.

Questions that help the dispatcher before the call

In a two-family house or a small apartment building, the first question is who else is affected. A clog that shows up on both floors points to a shared stack or a shared lateral, while a clog on one floor may be a branch line serving a single unit.

Landlords and property managers can speed things up by finding out which units have slow drains and which fixtures, and whether a basement floor drain is wet. If tenants share a laundry room, say so, because a washer can send a lot of water quickly into a line that is already narrowed.

Arrange access ahead of time where you can. The crew may need to reach a basement cleanout, a unit’s bathroom or the roof vent. Pricing is explained before work begins, and a camera after clearing shows whether the shared line needs a closer look.

Who to call first in a shared building

In a double or small apartment building, it helps to settle who calls before anything backs up. Tenants usually notice first, but the owner or manager decides on access to the basement and the cleanout. A short note in each unit with the number to call and where the shared cleanout sits saves time at night. When the crew arrives, the technician will ask which units were affected and in what order. A unit that floods first is usually the lowest one on the shared line, not necessarily the one that caused the clog.
