Safety First: Read This Before You Start
A little plumbing confidence goes a long way, but safety comes first.
- Turn water off before opening any fixture or line.
- Unplug electrical components and switch gas to Off for water heater work.
- Use proper PPE: gloves, eye protection, and knee pads.
- Never DIY gas lines, main sewer repairs, or pressure regulator replacements if you are unsure. Call a licensed plumber.
Two code-level facts to keep in mind:
- Under the International Plumbing Code, a pressure-reducing valve is required when supply pressure exceeds 80 psi. Residential water pressure should typically be 40 to 60 psi.
- Water heater temperature and pressure relief valves are safety devices rated to open near 150 psi or 210°F. Do not cap or plug a T&P valve discharge line.
Local tip: In many Metro Atlanta neighborhoods, the main water shutoff and pressure regulator are in a ground box near the curb. Inside shutoffs are commonly by the water heater or where the line enters the crawlspace or basement.
Dripping Faucet
A dripping faucet wastes hundreds of gallons per year and drives up your bill. Most leaks come from worn cartridges, O-rings, or seats.
How to fix it yourself:
- Shut off water to the sink. Plug the drain to avoid losing small parts.
- Identify your faucet type: cartridge, ball, ceramic disc, or compression.
- Remove the handle and trim. Take a clear photo for reassembly.
- Pull the cartridge or stem. Inspect and replace O-rings and seats. Use plumber’s grease on O-rings.
- Reassemble, open the water slowly, and test hot and cold.
Pro tip:
- If your faucet is older than 15 years, a full replacement may cost less than chasing parts. Modern faucets have ceramic cartridges that last longer and often carry lifetime finish warranties.
When to call a pro:
- Corroded valve body, seized parts, or if the shutoff valves under the sink will not close and need replacement.
Running or Phantom-Flush Toilet
A running toilet usually means a worn flapper, mis-set float, or a leaky fill valve. That “ghost flush” sound indicates a slow tank-to-bowl leak.
DIY steps:
- Remove the tank lid. Check the flapper for warping, slime, or cracking.
- Replace the flapper with the same style. Adjust chain slack to about 1/4 inch.
- Set water level to the mark inside the tank by adjusting the float.
- If water continues to run, replace the fill valve. Many kits include both components.
- Add a few drops of food coloring to the tank. If color shows in the bowl after 15 minutes, you still have a leak to address.
When to call a pro:
- Cracked tank, corroded bolts, or leaks at the base that suggest a failed wax ring or flange issues.
Slow or Clogged Sink and Shower Drains
Hair, soap, toothpaste, and grease cause most residential clogs.
DIY steps:
- Start with a zip strip to pull hair from the stopper area.
- Remove the pop-up assembly. Clean gunk from the pivot rod and tailpiece.
- Use a wet/dry vacuum to pull debris from the trap before you unscrew anything.
- Place a towel and bucket, then loosen the slip nuts and remove the P-trap. Clear the trap and inspect the trap arm.
- Reassemble with new washers if needed. Run hot water and test for leaks.
Avoid chemical drain cleaners. They can damage finishes and trap seals. Enzyme-based cleaners are gentler for maintenance after you clear the blockage.
When to call a pro:
- Multiple fixtures backing up at once, gurgling, or sewage smells. These suggest a main line problem that requires professional equipment to locate and clear stoppages.
Low Water Pressure at a Fixture
If pressure is low at a single faucet or shower, mineral buildup or a clogged aerator is likely.
DIY steps:
- Unscrew the aerator or showerhead. Soak parts in white vinegar for 20 to 30 minutes.
- Rinse, reassemble, and test. If pressure is still low, check supply lines for kinks or debris.
- For a tub spout or shower diverter that is stuck, replace the diverter assembly rather than forcing it.
House-wide low pressure can point to a failing pressure-reducing valve on the main line. Because the valve affects the whole home and must be adjusted and tested correctly, this is not a beginner DIY job.
When to call a pro:
- Pressure fluctuates or exceeds 80 psi. A licensed plumber can test and correctly size or replace the pressure reducer.
Garbage Disposal Jam or Humming
A humming disposal without grinding means a jammed flywheel or tripped thermal overload.
DIY steps:
- Unplug the unit. Never put your hand into the chamber.
- Insert a 1/4-inch hex key in the bottom socket and turn both directions to free the flywheel.
- Remove visible debris with tongs. Press the red reset button on the bottom.
- Restore power and run cold water while testing.
If the unit trips again or leaks from the body, the motor or seals may be done. Replacing the disposal is often faster and cheaper than rebuilding old models.
When to call a pro:
- Electrical issues, hardwiring concerns, or if the sink flange needs re-sealing with plumber’s putty.
Water Heater: Not Enough Hot Water
Sediment buildup reduces capacity and efficiency, especially if your heater has never been flushed. Most manufacturers recommend flushing a tank annually.
DIY steps for gas or electric tank-style heaters:
- Set the thermostat to Vacation. Turn gas to Pilot or flip the breaker Off for electric.
- Attach a hose to the drain valve. Open a hot faucet to break vacuum.
- Open the drain valve and flush until clear. Close the valve, refill, and purge air from hot faucets.
- Restore power or gas and set temperature to 120°F for safety.
If water smells like rotten eggs, replace the anode rod. This requires tools and clearance, so consider calling a pro if space is tight.
Important safety:
- Never cap a T&P relief line. Do not work on a tankless heater without following the manufacturer’s descaling procedure with isolation valves.
When to call a pro:
- Leaks at the tank body, repeated pilot outages, error codes, or any gas smell.
Small Leaks at P-Traps and Supply Lines
Under-sink drips are often caused by dried washers, misaligned slip-joint nuts, or cracked plastic traps.
DIY steps:
- Place a towel and bowl. Hand-loosen slip nuts and inspect washers.
- Replace washers and ensure the trap arm seats squarely into the wall stub-out.
- For braided supply lines, replace if older than 10 years. Hand-tighten, then add a quarter-turn.
- Turn water on and check for leaks with a dry paper towel.
When to call a pro:
- Corroded copper stub-outs, active leaks in walls, or if you see green corrosion at shutoff valves.
Sewer Stoppage Warning Signs
Frequent slow drains, gurgling in a tub when a toilet flushes, or sewage smells can indicate a main line issue. Older Metro Atlanta homes with clay or cast iron laterals are more prone to root intrusion.
What you can do now:
- Stop using water to prevent overflow.
- If safe, remove the cleanout cap outdoors to relieve pressure.
- Call a pro for camera inspection and proper clearing. This protects your line from damage and documents the condition for future repairs.
This is not a DIY auger job. Professional equipment and a trained tech can locate the root cause, map the line, and recommend long-term solutions.
When DIY Crosses the Line
Not every fix should be a weekend project. Call a licensed plumber if you encounter any of the following:
- Gas line smells, appliance connector issues, or code questions.
- Water pressure above 80 psi or no pressure after a main shutoff.
- Repeated drain clogs across multiple fixtures.
- Water heater leaks from the tank body or persistent error codes.
- Hidden leaks in walls, ceilings, or under slabs.

Preventive Maintenance That Actually Works
A small routine prevents big, expensive surprises. Focus on these items:
- Quarterly
- Clean aerators and showerheads.
- Test toilet flappers with the food-coloring check.
- Twice per year
- Inspect under-sink supplies and shutoffs for corrosion.
- Exercise main shutoff and note its location for the whole family.
- Annually
- Flush your water heater and test the T&P valve.
- Inspect exterior hose bibs and vacuum breakers.
- Check your water pressure with a gauge at a hose bib. Target 40 to 60 psi.

Frequently Asked Questions
What tools do I need for most small plumbing fixes?
A basic kit includes adjustable wrenches, slip-joint pliers, a basin wrench, plumber’s tape, replacement washers, a 1/4-inch hex key, a utility knife, and a wet/dry vacuum.
How often should I flush my water heater?
Most manufacturers recommend flushing a tank-style water heater once per year. This clears sediment, restores efficiency, and helps extend the life of the unit.
Is chemical drain cleaner safe to use?
Avoid harsh chemical drain cleaners. They can damage pipes, finishes, and traps. Clear the clog mechanically, then use enzyme-based products for maintenance.
What is normal home water pressure?
Typical residential pressure is 40 to 60 psi. If pressure exceeds 80 psi, a pressure-reducing valve is required by code and should be inspected or replaced.
When should I call a plumber instead of DIY?
Call a pro for gas smells, sewer backups, leaks in walls or ceilings, failed pressure regulators, and water heater tank leaks or error codes.
