In New York City and across Long Island – from Brooklyn brownstones to Suffolk County homes – plumbing problems often strike at the worst times. Whether it’s a dripping faucet, a clogged kitchen sink, or a malfunctioning water heater, the real challenge is knowing whether you can fix it yourself or need to call a professional.
This local plumbing guide breaks down the most common plumbing issues New Yorkers face, showing which ones are safe for a DIY attempt and which require professional plumbing service to avoid long-term damage.
DIY Plumbing Repairs You Can Handle (In Most Cases)
For small, isolated problems, you can often perform a simple repair yourself using basic tools. Here’s what’s generally safe to tackle:
1. Leaky or Dripping Faucets

What’s Happening:
A worn-out washer, O-ring, or cartridge can cause water to drip from your faucet continuously, wasting gallons and increasing your water bill.
Try This Fix:
Turn off the water supply under the sink. Disassemble the faucet carefully and replace the worn component. Most faucet repair kits are inexpensive and widely available at hardware stores.
Call a Plumber If:
The leak persists after replacement, the faucet is outdated, or the leak is part of a larger issue within the plumbing.
2. Minor Clogged Drains (Sink, Tub, or Shower)

What’s Happening:
Soap scum, hair, or grease may be slowing or blocking drainage. If it’s just one fixture, it might be a surface-level problem.
Try This Fix:
- Use a plunger or drain snake.
- For grease or soap buildup, carefully pour a pot of boiling water down the drain to help dissolve the buildup.
- Use a mix of baking soda and vinegar to help break things up.
- Clear the P-trap under the sink if you’re comfortable.
Call a Plumber If:
- Water backs up from multiple drains.
- The drain smells like sewage.
- You’ve used chemical cleaners, but the problem persists.
Professional Drain Cleaning is available from both Hardy’s Plumbing and Order A Plumber using hydro-jetting and sewer camera inspections.
3. Running or Noisy Toilets

What’s Happening:
The flapper or fill valve in your toilet tank may be loose, misaligned, or degraded – causing constant water flow and higher utility bills.
Try This Fix:
Open the tank and inspect the flapper and float. You can replace the parts using a toilet repair kit.
Call a Plumber If:
- The leak continues after replacing the flapper.
- The tank refills endlessly.
- There’s water pooling around the base of the toilet.
A running toilet can waste hundreds of gallons each day. Call Order A Plumber to stop the waste and protect your bathroom floor.
4. Low Water Pressure (Single Fixture)

What’s Happening:
Mineral buildup is a common cause, especially in older NYC buildings or areas with hard water.
Try This Fix:
Take off the faucet aerator or showerhead. Soak it in vinegar to clean it. Remove any debris. Rinse it and put it back on.
Call a Plumber If:
- Low water pressure is happening throughout your home.
- You hear banging noises (water hammer) or notice dirty water.
- There’s a sudden drop in pressure – it could indicate a leak or burst.
Licensed NYC plumbers from Order A Plumber and Hardy’s Plumbing can inspect the lines and restore proper pressure without major wall damage.
When It’s Time to Call a Professional Plumber

There’s a limit to DIY – and pushing past it can make matters worse. These issues require licensed plumbing professionals immediately:
1. Burst or Frozen Pipes
- Water damage spreads rapidly.
- Only pros can fully stop the flooding, cut out damaged pipe sections, and prevent mold or structural decay.

3. Hidden Leaks or Wall Damage
- Brown stains, musty odors, warped flooring – signs of slow, internal leaks.
- Plumbers use acoustic detection, thermal imaging, and moisture meters to pinpoint and fix damage before it worsens.
4. Water Heater Issues
- No hot water, water puddles around the heater, or strange noises?
- A bad thermostat, mineral buildup, or gas line issue could be to blame.
- Professionals like Order A Plumber handle tankless water heater repairs and replacements safely and quickly.
