Living or working in a high-rise building may be fantastic. Of course, with those fantastic vistas came the potential for plumbing issues. High-rises may provide some unique plumbing issues that you won’t usually find in a single-story home due to their height.
Plumbing Issues In High-Rise Communities
In high-rises, plumbing problems are not just a problem for the building owner; they can also lead to water damage, mold growth, and structural issues.
Many cities are home to a number of high-rise structures, many over 30 floors. Of course, even if you aren’t at the top of the skyline, you may be living or working in a skyrise. In the United States, a high-rise is defined as a structure that is more than 75 feet tall, or around seven floors, according to the National Fire Protection Association and most engineers and architects. Here are some frequent plumbing concerns to be aware of in high-rise buildings.
Water Pressure: Low Or High
In a high-rise structure, how does plumbing work? Buildings often let gravity do the job for them; water is pumped up from the city municipal water supply to a reservoir on the roof, then gravity pulls it back down via the building pipes. The reservoirs in newer skyscrapers are usually hidden within, and many tanks are typically employed throughout the structure (New York’s One World Trade Center has 16 water tanks).
A set of pumps will assist boost the water pressure to reach such high spots if a high-rise does not have a water reservoir. If you have an issue with low water pressure, a professionally fitted water booster system may assist.
Water is pushed into an airtight tank containing air, which is squeezed by the water entering the tank and forced higher by the water. Increasing the psi (pounds per square inch) on a typical system is riskier. Burst pipes and a slew of other issues might arise from exceeding municipal water pressure regulations.
Unmaintained Valves That Can Be Turned Off
Water shut-off valves, often known as safety valves, are an important part of high-rise plumbing design. A typical high-rise will contain shut-off valves for any exterior water features, such as fountains and sprinkler systems, as well as valves for each floor and apartment, maybe even every appliance.
These valves may be changed to the closed position in an emergency, halting water flow to specific locations and preventing catastrophic damage. Unfortunately, these values are not usually examined or maintained in a timely manner, resulting in low water pressure and poor drainage. To avoid this, high-rise buildings should have sensors and other plumbing equipment that can detect water leaks and cut off water to the leaking region automatically.
Drains That Are Often Clogged
Clogged drains are more common in high-rises, particularly commercial buildings (although individuals are more hesitant to flush strange things down the toilet in their own homes, they are less worried when it’s a place of business or an office space they’ll be leaving at 5 p.m.).
Clogs can occur in residential high-rises, and they may be a major issue if they cause a backlog throughout the building, affecting many units. Unfortunately, many residents and maintenance personnel may attempt to clean the pipe or drain with strong chemicals, which can cause even more difficulties.
These chemicals aren’t “smart,” and they can’t distinguish the difference between a pipe and a buildup of hair or grease since many of them include acid. As a result, they’ll attempt to munch their way through everything.
Building management should aim to encourage residents and employees in the habit of clearing clogs using a plumbing auger or snake. If the issue is serious, skilled plumbers can usually cure it by hydro-jetting, which is a process of clearing blockages with pressured water and washing them into the municipal system, where they are handled. It’s advised not to attempt DIY hydro-jetting since high water pressure might damage pipelines.
Flooding & Ceiling Damage
These two go hand in hand in a high-rise. This is due to the fact that flooding on one level of a building might result in ceiling and water damage on the floor(s) below. Floods are usually caused by clogged drains or broken water supply lines; these backups may subsequently create flooding from washing machines or dishwashers. Damage might be substantial due to the enormous amount of water used by these appliances.
A leaky water heater on the level above is another typical source of ceiling damage. Corrosion between pipes and joints or valves is the most common cause of leaks in older plumbing systems, particularly those built 20 years or more ago. While a major leak will usually be detected by the person below, if the unit is unoccupied, it may go undiscovered (a small leak can also be a problem, going unnoticed while quietly causing damage and mold growth). So be sure you obtain a yearly plumbing pipe check to catch any leaks or leaking pipes before it does too much harm.
Inadequate Drainage And Ventilation
The sole barrier between a drainage system and a building’s living/working area is the water trap seal. As a result, appropriate maintenance is essential to safeguard inhabitants from potentially dangerous gasses and microorganisms found in the drainage system. Because of the added force exerted on water trap seals by the building’s numerous units, high-rises need proper drainage ventilation.
Plumbing systems introduce atmospheric air into the plumbing drainage system to reduce stress. However, venting with pipes has limitations, as open vents require penetrations through the roof to allow air to balance the pressure within the drainage system. A professional plumber can determine whether there is Inadequate Drainage and Ventilation and may suggest Air Admittance Valves (AAVs) near the water trap seals that require protection. This has the benefit of eliminating the vent pipe network, the space required, and the roof penetrations, and greatly simplifies the design of a large plumbing drainage system.
High-Rise Plumbing Problems? Call A Professional
High-rise plumbing design is unique – so is high-rise plumbing maintenance! Building managers should ensure that the property’s plumbing is regularly checked so that the condition of pipes, water heaters, valves, and more can be evaluated. In addition, both tenants and managers need to be proactive and take steps to prevent damage and plumbing problems (be sure that everyone knows who to call when they have problems and what to do when there is a plumbing emergency).
Plumbing professionals use the most up-to-date business and residential plumbing technology, including trenchless pipe repair and replacement methods that don’t rip up your lawn. They can handle all of your high-rise business and residential plumbing requirements. To arrange a consultation and ongoing maintenance, contact one now.
Plumbing problems in high-rise structures can be difficult issues to address. There are many factors that come into play, but the most important is water supply.

Frequently Asked Questions
How does plumbing work in high rises?
A: In high rises, plumbing is done through the building’s central water supply. It comes from an overhead tank that supplies all of the units with a constant stream of fresh water.
What are the most common plumbing problems?
A: Dangers of blocked sinks and toilets, clogged drains, leaking pipes. If you have a leaky faucet or showerhead, it can cause damage to the water heater and flooring in your home. In severe cases, flooding may occur with untreated leaks.
