An owner-run plumber for Huntsville homes

Gerald Farrish Jr. started ABD Plumbing in 2013. He's an Alabama master plumber, and he still runs the company and works the jobs. Customers name him in their reviews. He picks up, comes out, and tells you what he'll do before he starts.

We work from our base in Decatur across north Alabama. That covers houses in Huntsville, Madison and Decatur and rentals for landlords. It also covers new commercial and government buildings, from the slab up.

Plumbing from under the slab to the finished shower

New builds and remodels across north Alabama

Some jobs are a single repair. Others start with bare dirt. On those we set the underground lines, run the rough-in, hang the fixtures and turn the water on, for new homes, remodels and commercial builds.

  1. PVC drain fittings and stub-ups with red and blue PEX lines in a gravel-bedded red clay trench, primer and cement cans nearby
    Underground Drains and supply lines set before the slab is poured.
  2. Two shower valve boxes with PEX lines roughed into a framed wall, drain stubs coming up through the slab floor
    Rough-in Drain, vent and supply lines run through the framing.
  3. Tiled walk-in shower with onyx-look walls, a pebble floor and niche, the valves set but not yet trimmed, boxes on the bench
    Trim-out Valves set and fixtures hung as the finishes go on.
  4. Large tiled walk-in shower with two dark bronze shower and handheld combos running, corner shelves on the wall
    Final Fixtures on, water on, every joint checked.

I needed a water heater quickly as my 17 year old gas water heater was leaking. I got a quote in a few days for a reasonable price. My new Bradford White water heater was installed the next day…
