Named Forbes' Top Ranked Plumbing Company of 2024!
Indian Hills is one of the most significant and enduring residential communities in Cobb County. Developed beginning in 1969 by Atlanta developer Thomas Cousins — the same developer who brought the Atlanta Hawks to the city — Indian Hills was at one point the largest single-family subdivision between Washington D.C. and Houston. Today the community encompasses approximately 1,680 homes on 2,000 gently rolling acres in the heart of East Cobb, centered around the Indian Hills Country Club with its 27-hole golf course, three swimming pools, eight tennis courts, and full dining and social amenities. The community's tree-lined streets, spacious lots, and strong school district affiliations have sustained its appeal for more than five decades.
Indian Hills was developed from 1969 through the early 1980s, which means the original homes in the community are now 45 to 55 years old. This places Indian Hills squarely in the vintage range where plumbing systems have the most complex service history in Cobb County — original copper supply lines that are well past their expected service life, cast iron drain lines subject to decades of internal corrosion and root intrusion, and water service lines that in many cases have never been assessed or replaced since original installation.
Pinhole leaks in older East Cobb copper are a documented regional pattern — studied closely enough that the Cobb County-Marietta Water Authority commissioned a 2018 forensic analysis by Virginia Tech on local pipe samples. The research pointed to a combination of contributing factors rather than a single cause: pipe age reaching the end of its service life, localized pitting corrosion on the inside of the pipe wall, and in some cases in-home conditions such as low-use, stagnant lines. In a community like Indian Hills where original copper plumbing dates to the late 1960s and 1970s, the pipe has been aging for five decades. Multiple pinhole leaks in different locations, recurring slow drains, and unexplained water bill increases are the patterns we see most consistently in homes of this age throughout East Cobb.
The heavily wooded character of Indian Hills — with mature oaks, pines, and hardwoods throughout the community's rolling terrain — also means tree root intrusion into sewer lines is among the most common service issues we encounter here. Root systems from trees planted in the early years of the community's development have had 50-plus years to extend toward buried drain lines.
Water heaters in Indian Hills homes typically represent second or third generation replacements, with the current units in many homes now approaching the 10-to-12-year replacement window. Sediment accumulates inside any tank water heater over time — annual flushing and anode rod inspection are the most effective maintenance steps for extending service life. For homeowners evaluating replacement, a tankless conversion is worth serious consideration in Indian Hills given the high hot water demand typical of larger homes in this community. We are one of the only plumbers in the Marietta area to offer a 10-year parts and labor warranty on Navien tankless installations.

Ethan was excellent right from start to finish! He was punctual, analyzed the problem, wrote up an estimate of cost and time required and completed as quoted. He was extremely polite, communicated as project progressed as well upon completion. I would definitely request Ethan for future work and highly recommend him.

I have known and worked with John for many years. Recently, we had a major leak involving a failed water heater. John replaced it and also arranged and coordinated removal of water damaged drywall as well its replacement prior to installation of the new water heater. We are pleased with the outcome and appreciated his dependability and reasonable price.

For a 1970s Indian Hills home with multiple pinhole leaks in different locations, the honest answer is almost certainly yes. When a home of this age starts producing pinhole leaks in different locations over a short period, it is exhibiting age-related pitting corrosion throughout the copper system rather than isolated failures. The pipe walls have been aging for 50-plus years. Continued spot repairs address each new failure but not the underlying condition. A whole-home repipe with PEX replaces the corroded copper with a material that isn't subject to the same pitting and is almost always the more cost-effective decision compared to ongoing repair cycles. We provide a full assessment and flat-rate pricing before any work begins.
Once per year is the standard recommendation, and it genuinely matters. Sediment accumulates inside any tank water heater over time and settles on the heating elements, reducing efficiency. The popping and rumbling sounds that many Indian Hills homeowners notice from their water heaters are the most common symptom of this accumulation — water trapped beneath the sediment layer heats and escapes through it during heating cycles. Annual flushing removes loose sediment from the tank floor, restores efficiency, and extends service life. If the unit is 8 or more years old and hasn't been serviced, a professional assessment will also tell you honestly whether repair and maintenance or replacement is the better investment.
Yes. Many Indian Hills homes have original water service lines — the pipe from the municipal main at the street to the home's main shutoff — that date to the original 1969–1980 construction. Lines of this age in Cobb County's soil conditions are worth assessing proactively. Signs of a failing service line include low pressure throughout the home, an unexplained water bill increase, or wet ground in the yard along the line route. Indian Hills's large lots and established landscaping make directional boring the preferred approach for line replacement — the new line is installed underground without open trenching, preserving lawns and mature plantings.
