Water heater installation and plumbing system maintenance

When Your Hot Water Stops, You Need It Fixed Today

You count on hot water every morning. When it stops, your whole routine stops with it.

A cold shower is one thing. A water heater that’s leaking, making sounds it never made before, or delivering water that looks or smells wrong is something else entirely. Not knowing whether you’re looking at a quick fix or a failing system makes the situation more stressful than it needs to be.

Universe Home Services sends out licensed plumbers who diagnose the problem accurately and tell you exactly what it will take to fix it. Contact us online to get scheduled today.

Your Neighborhood Has Licensed Plumbers Ready

A large share of Long Island homes deal with hard water from the tap, and Nassau and Suffolk County water carries the mineral content that accelerates sediment buildup inside water heater tanks, corrodes anode rods faster than in softer water markets, and shortens the working life of heating elements in electric units.

Universe has been serving Long Island homeowners since 1954, and our plumbers know what local water does to these systems because they’ve been repairing the results of it across Levittown, Merrick, Copiague, and communities throughout the island for decades.

Your Water Heater Repair, Step by Step

From your first call to the moment your water heater is working again, the path forward is straightforward.

Call or reach out online, and we’ll ask the right questions about your water heater: type, fuel source, age, and what you’re experiencing. Same-day service is available across Long Island in most cases, or immediately when there’s an active leak.

Your plumber arrives on time and starts by hearing what you’ve noticed: the symptoms, when it started, anything that changed recently. From there, the full system gets inspected. Tank, thermostat, heating elements or burner, anode rod, pressure relief valve, supply connections, and flue if applicable. Water heater problems aren’t always what they look like on the surface, and the goal is the root cause.

Once the diagnosis is complete, you’ll hear what was found in plain language and receive the cost before any work begins. Once you approve, the repair is completed using quality parts, and the system is tested before your plumber leaves.

Even though it was a bit pricey Nick the plumber was very professional and did a good job.๐Ÿ‘๐Ÿผ
Came home to a leak in my garage ceiling on Monday – Karl found the problem and fixed it by noon on Wednesday. He even put up with my awful roommate. Great guy. Great job.
Vidal was such a professional and a clear subject matter expert. We were unfortunately too far away on price, but he was so great throughout the process. Looked at the job thoroughly and provided great recommendations I hadnโ€™t thought of. Wish we were closer on price but I think I may be out of touch on the market. Thanks Vidal!
Rich was knowledgeable about our AC system and he explained clearly what he was doing and gave tips on ways to keep it running soundly. I would definitely want Rich to come back for future maintenance to our AC & heating systems.
Chris did a great job in servicing my boiler. He was attentive, patient, and detail oriented. Never felt like he was rushing or taking short cuts. I would recommend him to anyone needing heating service.
Brandon came to my house for a water leak. He went above and beyond to find the leak. He told me a few things to do to eliminate the possibilities. He found the leak and corrected the problem. He explained everything that he was doing and what would happen. Finally today installed a new bowl without issue. Great job Brandon, thanks for everything
Excellent. Each one of your technicians was professional and informative. Problem resolved!

This company provides good service… The technicians are competent, courteous and prompt… I highly recommend this company.
Brandon was able to install a PVB for my irrigation system to keep me in compliance with Federal law and I sure liberty water did not turn off my system. Brandon showed up the next day after I called, he completed the work in less than two hours. He was polite and explained what he was doing, even took the time to install extra hose bibs to ensure it was easier for me to blow out the system. I will ask for him again if I have a plumbing issue.

Signs Your Water Heater Needs Repair

Water heater problems show up in different ways depending on what’s actually failing.

Our licensed plumbers handle the full range of issues, from sediment buildup to thermostat failures to pressure concerns.

A water heater that produces no hot water at all, or that runs out faster than it used to, points to a failed heating element in electric units, a burner or thermocouple issue in gas units, or a thermostat problem in either. Long Island’s hard water accelerates element corrosion in electric water heaters across Hicksville, Bethpage, and Plainview, so the diagnosis identifies which component has failed and what it takes to restore full capacity.

A thermostat that’s reading incorrectly or failing to hold its setting delivers water at the wrong temperature regardless of how you adjust it. This is one of the more common service calls we handle in older homes around Levittown, Hempstead, and Westbury where original water heater equipment is often pushed well past its service life. Testing, calibrating, or replacing the thermostat gets your system responding to your settings correctly.

That rumbling or popping sound from your water heater tank almost always points to sediment buildup on the bottom. Nassau County’s hard water deposits calcium and magnesium as scale over time, and that scale traps water underneath it that steams and pops during heating, which is why homeowners in Wantagh, Seaford, and Baldwin call us for this regularly. Flushing the tank and clearing the sediment gets the system running quietly and efficiently again.

When your hot water runs rusty or brown, the cause is usually corrosion inside the tank or a depleted anode rod that’s no longer protecting the tank lining. A sulfur smell in hot water usually means bacterial growth in a tank set too low. This is a common call from homes in Massapequa, Bellmore, and Oceanside where older tanks run cooler than current code recommends. The anode rod gets inspected and replaced if needed, and the system is brought to correct operating temperature.

A leak at the supply connections is often a fitting that can be reseated or replaced, which is the most common call we get from split-level and ranch homes across Syosset, Mineola, and Garden City where original copper fittings have aged out. A leak from the pressure relief valve means the valve is doing its job by discharging to prevent overpressure, but the underlying pressure issue still needs to be found. A leak from the tank itself is a different conversation, and you’ll hear honestly what the leak source means for the system before any decision is made.

A pressure relief valve that’s discharging, dripping, or has never been tested is a safety issue, because this valve protects your water heater from dangerous overpressure. We handle these calls regularly in Lindenhurst, Amityville, and Babylon, where older installations often have valves that were never tested after the original install. Testing the valve, replacing it if it isn’t functioning correctly, and confirming system pressure is within safe range keeps your home protected.

Should You Repair or Replace Your Water Heater?

When your water heater needs a significant repair, replacement is a fair question to ask.

Both options get an honest read with no pressure in either direction, based on the system in front of us and what the next five years look like.

Tank water heaters typically last 8 to 12 years, but hard water on Long Island shortens that range by accelerating corrosion and sediment buildup inside the tank. A unit under 8 years old with an isolated component failure is almost always worth repairing, while one past 10 to 12 years facing a significant repair, especially if the tank itself is corroding, is worth a replacement conversation.

A water heater that has needed service more than once in the past year is wearing out across multiple components. When repair costs approach half the cost of a new unit, replacement delivers more reliability per dollar than continued investment in aging equipment.

An older water heater losing efficiency runs longer to deliver the same amount of hot water, which shows up on your energy bill. On Long Island, where PSEG electricity rates run among the highest in the country, the monthly savings from a newer high-efficiency unit add up faster than in most other markets.

A tank showing rust on the exterior, a history of leaks from the tank body itself, or corrosion visible at fittings and connections has reached the end of its practical life. Your plumber gives you an honest assessment of what’s actually in front of them before any decision is made.

Frequently Asked Questions About Water Heater Repair

How do I know if my water heater needs repair or replacement?

Age and the nature of the failure are the two biggest factors. A water heater under 8 years old with a failed thermostat or heating element is almost always worth repairing, while one past 10 to 12 years with a leaking tank, heavy corrosion, or a pattern of failures is usually a replacement candidate. On Long Island, where hard water shortens working life across Nassau and Suffolk County, pattern of failure is often the clearer signal than age alone. A licensed plumber gives you an honest read after seeing the system.

Is a leaking water heater dangerous?

It depends on where the leak is coming from. A dripping pressure relief valve means the valve is doing its job, but something is driving excess pressure that needs attention. A leak at supply connections is usually straightforward, while a leak from the tank body itself points to internal corrosion. Any active leak warrants a call, and one spreading water across the floor warrants an emergency call given how quickly water damage compounds in finished Long Island basements.

How long does a water heater repair typically take?

Most water heater repair calls are completed in a single visit. Common repairs including thermostat replacement, heating element replacement, anode rod replacement, and tank flushing are handled with parts carried on the service vehicle. More complex repairs involving gas supply components or pressure relief valve replacement may require additional time or a parts order.

Does hard water really affect water heaters on Long Island?

Yes, significantly. Nassau and Suffolk County water carries mineral content that deposits as scale inside the tank and on heating elements over time, which reduces efficiency, causes the rumbling and popping sounds homeowners notice, and shortens the working life of the unit. Annual maintenance that flushes sediment and inspects the anode rod is the most effective way to offset it, and a whole-home water softener addresses the issue at the source.

Do you repair both tank and tankless water heaters?

Yes. Universe services both traditional tank water heaters and tankless units, covering gas and electric models across all major brands. If you want to confirm we service your specific equipment before scheduling, reach out and we’ll confirm.
