Drain Repair in Hiram, GA

Drain repair looks different depending on what the pipe is made of. Homes in Hiram range from older houses with metal drains to newer ones plumbed entirely in plastic, and many have a mix after a remodel or two. Knowing which material you have helps make sense of the symptoms and the repair options. Alpha Plumbing and Sewer works on interior and branch drains made of all the common materials and joins new pipe to old where they meet.

Cast iron

Heavy, quiet and long-lived, cast iron was standard for drains and stacks in many older homes. It corrodes from the inside, so the bottom of horizontal runs can thin and crack while the outside looks fine. Rough interior scale catches debris, which is why older cast iron lines tend to clog over and over. Repairs usually involve cutting out the failed section and replacing it with plastic pipe joined by shielded couplings, with the remaining iron well supported.

Galvanized steel

Galvanized pipe shows up on smaller drain branches, trap arms and vents in some older houses. The zinc coating wears away over decades, and the steel rusts inside, especially at the threaded joints. A galvanized trap arm can close down to a fraction of its original opening before it ever leaks. When galvanized drain fails, replacing the run rather than one fitting is usually the sensible approach, since the rest is likely in similar shape.

ABS and PVC plastic

Black ABS and white PVC have both been used in homes for decades, and PVC is the usual choice in new work and remodels today. Neither corrodes. Failures are more often about installation than age: a joint that was not fully cemented, a pipe stressed by poor support, or damage from a nail or screw driven through a wall. Where a plastic drain slows down, the cause is more often a sag, a flat run or buildup from grease and soap than any breakdown of the pipe itself. ABS and PVC take different cements, so a transition between them is made with a coupling or fitting designed for the purpose.

Brass and copper

Chrome-plated brass traps are common under older bathroom sinks, and some houses have copper drain or vent lines. Thin brass traps corrode through at the bottom of the bend, while copper drain lines can develop pinholes or cracked joints over time. Both are usually replaced with plastic, although a metal trap may be kept where it shows under a pedestal sink.

Where materials meet

Many problems happen at the transitions. An old rubber-and-clamp coupling can loosen, a threaded adapter between galvanized and plastic can corrode, and a joint made with the wrong fitting can leak or sag. When a section is replaced, the connection to the existing pipe on each end deserves as much attention as the new pipe. A camera inspection helps show which material runs where inside walls and floors, and how sound it is near the planned joint. For deep cleaning of a line in good shape, hydro jetting may be an option, though it does not suit fragile metal drains.

Who handles permits for Hiram addresses

The city of Hiram refers building permit questions to Paulding County's Development Division, so the county is the place to ask about a drain repair permit. Paulding County's Building and Permitting Division issues plumbing permits for every type of property, and its own building inspectors handle the inspections that go with them.

Questions about drain pipe materials in Hiram

How can I tell what my drain pipes are made of?

Look where the pipes are exposed: under sinks, in a basement, a crawlspace or an unfinished utility room. Black plastic is ABS, white or cream plastic is usually PVC, heavy dark metal with wide bell-shaped joints is likely cast iron, and threaded gray metal is often galvanized steel. A plumber can confirm hidden sections with a camera.

Is PVC better than cast iron for drain repairs?

Each has strengths. Cast iron is quieter, which some homeowners notice in stacks near bedrooms, while PVC is lighter, does not corrode and is easier to install in tight spaces. For replacing sections of an existing cast iron line, plastic joined with proper couplings is standard; for a whole stack, the choice can depend on noise concerns and access.

What causes leaks where new and old drain pipes are joined?

Most leaks at transitions come from couplings not suited to the two materials, from poor support that lets the heavier pipe pull on the joint, or from corrosion on a threaded metal adapter. Using a coupling designed for the specific pipes, cutting the old pipe cleanly and supporting both sides of the connection prevents most of these problems.
