Plumbing Services in Sandy Springs, GA

Adding a fixture sounds simple until you ask where its water will come from and where its waste will go. A sink, toilet or shower needs a supply line, a drain with enough slope, a vent and, for hot water, a heater that can keep up. When Sandy Springs owners plan one of these additions, Alpha Plumbing and Sewer's plumbing services begin with the same five questions on almost every project.

Where will the waste go?

Drains work by gravity, so a new fixture needs a path downhill to an existing drain or the building sewer. Smaller drain lines are commonly run at about a quarter inch of fall per foot, which adds up over a long run and can push the pipe below floor joists or into a slab. A wet bar on an interior wall near a kitchen drain is usually easy. A bathroom on the far side of the house from the nearest stack may need a long run, a new branch or cutting concrete. On a slab, trenching for a new drain line is planned like new construction plumbing, with the pipe inspected before it is covered.

How will it vent?

Every trap needs air behind it, or the water seal gets siphoned out and sewer gas comes through. A new fixture may tie into a nearby vent, need a new vent pipe up through the roof, or, where the code and the inspector accept it, use a mechanical air admittance valve. Venting is the part homeowners most often overlook when sketching a layout, and it can decide which wall a sink goes on.

Is the new fixture below the sewer?

A basement bathroom or bar sink may sit lower than the sewer line leaving the house. If gravity cannot carry the waste out, it goes to a sealed basin where a sewage ejector pump lifts it up to the main drain. That adds equipment, an alarm and a dedicated circuit, and it brings its own maintenance needs, which Alpha handles through sump and sewer pump service. Gray-water fixtures such as a laundry sink can use a smaller pump.

Can the supply and the hot water keep up?

Adding a shower to a house already short on hot water makes mornings worse. Look at the water heater's capacity and first-hour rating, and at how far the new fixture is from it, since a long run means a long wait for hot water. Options include upsizing the tank, adding a recirculation line or installing a point-of-use or whole-house tankless water heater sized by flow rate. Supply pipe size and pressure matter too, especially when a third or fourth bathroom draws from an old, narrow main.

Is the main line ready for more?

A new bathroom adds flow to a sewer line that may already be struggling. In an older house, or one with a history of slow drains, a sewer camera inspection before the addition is worthwhile. Roots, sags or a cracked section are far easier to fix before new finishes go in, and the camera also shows the depth and direction of the line, which helps plan the new connection. If the footage shows a failing line, main sewer line repair can be scheduled ahead of the project.

Common additions and what they usually involve

• Wet bar or coffee station: a small sink near an existing drain and supply; venting is the main question.
• Second-floor laundry: a standpipe drain, hot and cold supply, a drain pan and a route down through the walls.
• Basement bathroom: often an ejector basin, plus venting tied into the existing system.
• Converting a half bath to a full bath: a shower drain, larger supply and often a hot water review.

Sandy Springs permits for added fixtures

The city's plumbing permit page calls for a permit on residential plumbing projects, and residential permits can be pulled by contractors or by owners for their current permanent home. They are often issued over the counter, and the work gets a rough inspection and a final. For an added fixture, the rough inspection happens while the new pipe is still visible.

Questions about adding plumbing in Sandy Springs

Can a bathroom go anywhere in the house?

Almost anywhere is possible, but not everywhere is practical. The deciding factors are how far the new drain must run to reach an existing line with proper slope, how it will be vented and whether it sits below the sewer. A location near an existing stack or a plumbing wall usually costs far less and disrupts less than one across the house.

Does adding a sink in Sandy Springs need a permit?

According to the city's plumbing permit page, residential plumbing projects need a permit, with simple repairs such as unclogging a sink excluded. Adding a sink means new drain, vent and supply piping, so it is a project rather than a repair. If the sink is part of a larger remodel under a building permit, the plumbing can be covered by that permit.

How do basement bathrooms drain if they are below the sewer?

Waste flows into a sealed basin set into the floor, and a sewage ejector pump lifts it up into the main drain line when the basin fills. The system needs a vent, a check valve, a dedicated electrical circuit and an alarm. Choosing the right basin and pump size depends on the fixtures connected to it.
