When Should I Replace My Water Heater or Boiler?

Storage water tanks last roughly 15 years. It’s usually most cost-effective to replace a troublesome tank that requires frequent repairs. Additionally, broken boilers and water heaters can cause sanitation problems. Besides age, take note of the following:

  • Strange noises
  • Irregular water taste, smell, or color
  • Leaks or flooding
  • Water not heating up

When Do I Need Repiping?

If you’re in an older building with outdated piping, it can potentially hurt your bottom line over time. Leaks can increase your utility bills and cause water damage. Chivalry Plumbing, Heating & Cooling can replace partial or whole plumbing systems with sturdy new pipes. The following indicate you may need repiping:

  • Low water pressure
  • Mildew, mold, and water damage
  • High water bills

The winter of 2025-2026 was pretty brutal, with temps in single digits on some days. I had shut off our first floor baseboard heating due to a leak somewhere in the water pipe system. However the old Levitt house we live in have the pipes embedded into the concrete slab (no basement) so finding the leak was especially challenging. Our HVAC system plus the Dyson Heating unit DID NOT provide enough heat during the cold nights. In March we finally called several plumbing contractors to see how the leak can be detected and repaired. Only Chivalry offered using thermal imaging gun to try to narrow where the leak might be. Eric and Rich came out to perform the scan and identified two possible leak locations. The first potential leak site was in the kitchen. They were able to limit removing just a single 18×18-inch tile to access the pipe, but this location showed no leak. The second location, near the back door, required cutting through laminate flooring, and that is where they found the leaking pipe. Replacing the leaking pipe section was fairly standard. But the hardest part was finding the leak. We are grateful for Eric and Rich's detective work and the repair done to restore our baseboard heating. Now we can look forward to a warm winter next year. PS. Its up to the homeowner to repair the surface AFTER the digging, which I was able to do myself. Luckily, I kept some tiles and floorboards.

I’ve been meaning to write this for a while. Back in Fall 2025, Chivalry Plumbing installed our new boiler and removed the old one, and the whole experience was excellent from start to finish. Will, Anthony, and Eric were fantastic to work with. They were professional, respectful of our home, and incredibly clean and neat throughout the entire process. What really stood out was how efficiently they worked. They completed a full boiler installation and removal in just one day, and the setup they put in is top notch. We couldn’t be happier with the quality of the work. I highly recommend Chivalry Plumbing to anyone looking for reliable, skilled, and courteous service.

I had a serious gas leak in ny 1923 house in Elmont. Being that others on the job have used this company, I figured I would give them a try. They sent out David in a timely manner being that the main was turned off by the Regs. David was informative and patient with my cost concerns and product placement with sheet rock being cut away. I can say that he did his honest best and gave me 2 quotes which I could swing. There was a payment plan available on there website if I wanted that route. I feel that this company has excellent customer service. They chose wisely with David and Anthony that partnered him on the large job that was done in a day. I recommend this company and ask for these 2 men as they are the best when I was seriously overwhelmed.

    When Should I Replace Sinks and Toilets?

    Do your restrooms have fixtures more than 25 years old? Remodeling could lower your operating costs. Some old toilets require as many as seven gallons per flush. That’s more than four times the current U.S. manufacturing standard. The EPA estimates an office building with 1,000 occupants could save almost $10,000 a year by upgrading to WaterSense labeled toilets, for example.
