Older homes throughout Syracuse and Central New York often contain plumbing systems that have remained largely untouched for decades. In many cases, those systems continue functioning well enough that homeowners never realize there may be underlying weaknesses hidden behind walls, beneath floors, or inside aging shutoff valves — until renovation work or plumbing service requires the system to be put to use again.
While homeowners naturally focus on the new materials being installed during a remodel, some of the biggest risks in older homes are often the pre-existing systems already hidden behind the walls.
This recent project became a perfect example of that reality.
Case Study: Basement Flood After Syracuse VA HISA Grant Tub-to-Shower Conversion
This project began as an accessibility-focused tub-to-shower conversion completed with help from the VA HISA Grant program for a veteran in the Syracuse area.
The existing bathtub had become increasingly difficult and unsafe to step over comfortably, and the goal of the remodel was to create a safer walk-in shower environment that would allow the homeowner to remain in the home long-term.
From a construction standpoint, the remodel itself progressed exceptionally smoothly. The existing tub enclosure was removed and replaced with a custom cultured stone walk-in shower system designed specifically for accessibility, ease of use, and long-term durability. Like many accessibility-focused remodels completed throughout Central New York, the project focused heavily on safety, practicality, and reducing future maintenance concerns. All plumbing directly associated with the shower area itself was replaced during installation.
At Bath Pros, we generally don’t believe in reusing decades-old plumbing connections behind newly finished shower walls whenever replacement is practical. Older shutoff valves and aging plumbing components can become unpredictable once disturbed after sitting untouched for decades. We’ve even written an extensive comparison discussing the differences between common plumbing valve manufacturers and why valve quality matters long-term. While replacing plumbing during a remodel increases labor and material costs slightly, it significantly reduces the likelihood of concealed leaks developing behind finished walls later. To complete that work safely, the home’s water supply had to be temporarily shut off.
This is standard procedure during virtually any legitimate plumbing renovation. Because this older home did not contain localized shutoff valves serving only the bathroom area, the home’s main shutoff valve had to be operated during installation. Once plumbing work was completed, the water supply was restored, the system was carefully checked, and no active leaks or plumbing concerns were visible at the time. The homeowners were thrilled with the final shower.
About a week later, however, the phone rang. The homeowner reported significant water accumulation in the basement. Situations involving water intrusion understandably create concern very quickly for both homeowners and contractors alike. Water damage can affect stored belongings, drywall, flooring, framing, insulation, and other materials if not addressed promptly. Because we take these situations extremely seriously, Bath Pros responded quickly to investigate. At first glance, the homeowners naturally assumed the newly remodeled shower may somehow have been responsible. However, several observations immediately suggested otherwise.
The new shower itself showed no signs of leaking. There was no active water intrusion beneath the remodeled bathroom area, no visible water migration through framing beneath the bathroom, and no evidence suggesting the newly installed shower plumbing had failed. Instead, the moisture appeared to be originating from an entirely different section of the home’s plumbing system located within the basement. That discovery shifted the investigation toward the home’s older plumbing infrastructure.
The Real Cause: An Aging Shutoff Valve
After further evaluation, the issue appeared to involve an older-style gate valve serving the home’s main water supply.
Older gate valves are extremely common throughout older homes in Syracuse and Upstate New York. Many of these valves remain untouched for decades at a time. While they may appear externally to be functional, years of mineral buildup, internal corrosion, aging seals, and deterioration of internal packing material can leave them vulnerable once they are finally operated again.
We have actually seen situations like this firsthand during past remodeling projects. In one particularly memorable Bridgeport, NY bathroom remodel case study involving an overnight plumbing leak, an older vanity shut-off valve failed overnight after floor leveling work required the vanity to remain disconnected until the following day. That experience permanently changed some of our company’s plumbing and remodeling standard operating procedures moving forward.
In many cases, older shutoff valves may sit dormant for years without visible leakage — only to begin seeping around the valve stem or packing area after being shut off and reopened during legitimate plumbing work.
This is not unique to bathroom remodeling projects. Similar situations are encountered regularly during:
- water heater replacements
- plumbing repairs
- boiler work
- fixture replacements
- emergency plumbing service
- whole-home shutoffs
In this particular case, the aging valve assembly appears to have developed seepage after the home’s water supply system was temporarily isolated and restored during legitimate plumbing work.
Why Older Shutoff Valves Can Become Difficult to Service
Initially, there was concern that the valve may require replacement, which would have required shutting off the home’s water supply externally. In many older neighborhoods throughout Central New York, locating individual curb-stop shutoff valves is not always straightforward. Frequently, these valves have not been accessed in decades and may be buried beneath soil, landscaping, overgrown grass, or previous property work.
During the investigation, multiple larger water mains serving the surrounding area were identified, along with a separate line feeding the neighborhood’s fire hydrants. However, the individual residential curb-stop serving the home itself could not immediately be located without additional tracing equipment.
Situations like this are more common in older homes than many homeowners realize.
How the Valve Was Stabilized Without Invasive Plumbing Repairs
After evaluating the situation, Bath Pros Operations Manager Joshua Brodnicki was ultimately able to stabilize the issue without cutting into or replacing any plumbing components. Using a process commonly referred to as “exercising the valve,” the older gate valve was carefully and gradually worked open and closed in small, controlled increments rather than being forced abruptly.
This process involves slowly moving the valve stem forward and backward over time in order to help redistribute and reseat the internal packing material surrounding the valve stem assembly. Older valves often rely on packing material such as graphite, Teflon, or rubberized sealing components to prevent seepage around the stem when the valve is adjusted. After sitting untouched for decades, that packing material can dry out, compress, harden, or shift position internally.
In some situations, carefully exercising the valve combined with a very minor adjustment to the packing nut can slightly recompress the packing material against the stem and stop minor seepage without requiring immediate invasive repairs.
In this particular case, a very small adjustment to the packing nut — less than a quarter turn — combined with gradual exercising of the valve was enough to stop the seepage completely. The valve was monitored carefully afterward and remained completely dry. Importantly, no municipal water infrastructure was disturbed, no plumbing lines were cut open, and no emergency excavation or invasive repairs were ultimately required.
Addressing the Remaining Basement Water
While the valve issue itself was stabilized successfully, there was still residual water remaining within portions of the basement that required cleanup and drying.
The homeowners’ son happened to be visiting from Florida at the time, and recommendations were made to:
- remove standing water using a wet vacuum,
- keep fans and dehumidifiers running continuously for several days,
- promote airflow throughout the basement,
- and monitor the area carefully while everything dried thoroughly.
As with any moisture-related event, proper drying afterward is important in helping reduce the risk of lingering moisture-related issues.
Fortunately, the homeowners were extremely relieved once the source of the seepage was identified and stabilized.
What Is the VA HISA Grant Program?
The VA HISA Grant — short for Home Improvements and Structural Alterations — helps qualifying veterans complete medically necessary accessibility improvements within their homes.
Common qualifying projects include:
- walk-in showers
- ADA accessibility improvements
- grab bars
- widened doorways
- wheelchair accessibility modifications
- safer bathroom layouts for aging veterans
Many older veterans throughout Syracuse and Central New York continue living in homes built decades ago, which means accessibility remodels frequently intersect with aging plumbing, electrical, and structural systems that may not have been disturbed in many years.
That reality is one of the reasons experience matters when remodeling older homes.
Why Remodeling Contracts Often Exclude Pre-Existing Plumbing Conditions
One of the most misunderstood aspects of remodeling older homes is the distinction between:
- new plumbing installed during the remodel itself,
- and the home’s broader pre-existing plumbing infrastructure.
As remodeling contractors, we can evaluate visible plumbing and replace systems directly associated with the bathroom being renovated. What cannot realistically be predicted, however, is the condition of every aging shutoff valve, buried fitting, water line, or hidden plumbing component throughout an older home. Otherwise, every bathroom remodel would require:
- extensive exploratory demolition,
- whole-home plumbing replacement,
- and large-scale preventative repairs unrelated to the actual scope of work.
That simply is not realistic for most homeowners. Still, situations like this are exactly why we believe in responding quickly, investigating thoroughly, communicating honestly, and helping homeowners navigate unexpected conditions whenever reasonably possible.
Remodeling Older Homes Throughout Syracuse, NY
Homes throughout Syracuse and Central New York contain some of the oldest housing stock in New York State. While that older character can be beautiful, it also means many plumbing, electrical, and structural systems were installed generations ago under very different standards than those used today.
Successfully renovating older homes requires more than simply installing new products. It requires understanding how aging infrastructure sometimes behaves once construction begins interacting with those systems, which may not have been touched in decades.
At Bath Pros, we believe homeowners deserve honest conversations about those realities before remodeling work ever begins.

FAQ
Can turning water off during a bathroom remodel cause old plumbing valves to leak?
Yes. Older shutoff valves that have not been operated in many years can sometimes begin leaking after being shut off and reopened during legitimate plumbing work. In many cases, the issue involves aging internal packing material, worn seals, mineral buildup, or corrosion within older gate valves.
What is a gate valve?
A gate valve is an older style of water shutoff valve commonly found throughout older homes in Syracuse and Central New York. Unlike newer quarter-turn ball valves, gate valves use an internal threaded stem and gate assembly to stop water flow. Over time, these valves can become difficult to operate or begin leaking around the valve stem area.
Why do older shutoff valves fail after being used?
Many older shutoff valves remain untouched for decades. When finally operated during plumbing repairs or bathroom remodeling work, internal seals or packing material may shift, dry out, or fail due to age and corrosion. This can sometimes cause seepage around the valve stem or packing nut area.
Can an older leaking shutoff valve sometimes be repaired without replacement?
In some situations, yes. Minor seepage around the valve stem can occasionally be stabilized by carefully exercising the valve and making a small adjustment to the packing nut. However, severely deteriorated valves may still require replacement by a licensed plumber.
Why do remodeling contracts exclude pre-existing plumbing conditions?
Bathroom remodeling contractors can replace plumbing directly associated with the remodeled area, but they cannot realistically predict the condition of every hidden pipe, shutoff valve, or aging plumbing component throughout an older home. Because of this, most remodeling contracts exclude failures involving unrelated pre-existing plumbing infrastructure outside the project scope.
What is the VA HISA Grant?
The VA HISA Grant — short for Home Improvements and Structural Alterations — helps qualifying veterans complete medically necessary accessibility improvements within their homes. Common projects include walk-in showers, ADA accessibility modifications, grab bars, and safer bathroom layouts for aging veterans.
