Common Tankless Water Heater Problems We Handle
If your system is not working the way it should, there is usually a clear symptom that brings you to this page. You might turn on the tap and get only cold water, or the water may swing from hot to lukewarm without warning. In some homes and businesses, the tankless unit shuts itself off during use, or you may see an error code on the display that will not clear.
Other problems involve performance rather than total failure. You might notice reduced hot water flow in a top-floor apartment, temperature drops when more than one fixture runs, or delays before hot water reaches distant fixtures. In commercial kitchens, staff might report that dishwashing or cleaning takes longer because water is not staying consistently hot.
Behind these symptoms, several contributing factors may be at play. Mineral buildup in heat exchangers, partial blockages in supply or drain lines, issues with gas supply, and venting problems can all affect how a tankless system performs. Because our team is equipped to handle full sewer and drain service, we can look beyond the surface and address related piping or stoppage issues common in older Brooklyn buildings and mixed-use properties.
What To Do If Your Tankless Water Heater Fails
If your tankless water heater stops working, there are a few practical steps you can take while you contact a professional. First, check whether the problem is limited to one fixture or affects all the hot water in the property. If every tap produces only cold water, or the unit repeatedly shuts off or displays an error code, that is a sign you need qualified help.
It can be helpful to note what you see before our technicians arrive.
Here are simple ways you can prepare:
- Write down error messages. Record any codes or lights displayed on the unit.
- Notice when problems occur. Pay attention to whether the issue happens only during peak usage or every time you turn on the hot water.
- Check for visible leaks. Look around the unit and nearby piping for dripping water or damp areas.
- Keep the area clear. Make sure we can easily access the unit and any nearby shutoff valves.
If you notice leaks around the unit or nearby piping, or if you smell gas, treat the situation as urgent. In those cases, avoid attempting repairs yourself and focus on keeping people away from the affected area. You can then call us for guidance and emergency response. When the issue is less severe but still disruptive, we can schedule a prompt visit, provide a free estimate before any major work, and explain your options so you can decide how to proceed.

Frequently Asked Questions
Do you repair tankless water heaters in older Brooklyn buildings?
Yes, we regularly work on tankless units in older buildings, including brownstones, pre-war walkups, and mixed-use properties. Since 1987, we have been handling sewer and drain work in New York City, which has given us extensive experience with aging pipe networks, tight basements, and complex layouts. That background helps us diagnose how issues in existing plumbing can affect a modern tankless system. We also understand that these buildings may have unique access rules or limited spaces, and our technicians plan their work accordingly.
Can you work on tankless systems in restaurants or commercial spaces?
We do service tankless water heaters in restaurants and other commercial properties. Our team already supports a wide range of commercial and municipal clients, including hospitals, schools, fire departments, and large management firms, so we are accustomed to working in environments where hot water is critical to daily operations. When we schedule work for a business, we discuss your operating hours and any special requirements so we can plan repairs to minimize disruption. Our goal is to help you maintain safe, comfortable conditions for staff and customers while we address the issue.
How much does tankless water heater repair usually cost?
The cost of repairing a tankless water heater can vary because each property, unit, and problem is different. Factors that affect price include the nature of the issue, access to the equipment, any related sewer or drain problems, and the parts or labor required to correct it. At All County Sewer & Drain, we provide competitive, transparent pricing and free estimates, so you can review costs before approving major work. During our visit, we explain what we found, what it will take to fix, and why, so you can make an informed decision.
Will you tell me if I need a new unit instead of a repair?
When we evaluate a tankless system, we look at its age, condition, service history, and the type of problem it is having. If we believe a repair is practical and makes sense in the long term, we will explain the work involved and proceed with your approval. If the unit is failing repeatedly, has significant wear, or is nearing the end of its expected service life, we will share that information and outline your options. Our role is to provide you with clear, honest information so you can decide whether repair or replacement is the better option for your property and budget.
What should I do before your team arrives to check my tankless heater?
Before our technicians arrive, you can take a few simple steps to prepare. Make sure we can access the tankless unit and any nearby panels or shutoff valves by clearing the immediate area. Note any error codes or display lights, and when the problem tends to occur, such as only during certain times of day. Avoid removing covers, attempting internal repairs, or working on gas lines yourself, as these tasks can pose safety risks. When we arrive, we will handle the technical work and walk you through what we find.
