Fix It Yourself: Practical Household Repairs That Actually Work

---

1. Quiet a Running Toilet That Won’t Stop Filling

A toilet that runs constantly wastes water and money, but it’s usually caused by a simple part failing inside the tank.

What You’ll Need

• Adjustable wrench (optional)
• Replacement flapper or fill valve (if needed)
• Towel or sponge

Step-by-Step

1. **Remove the tank lid and observe.**

Flush the toilet and watch what happens inside the tank. Pay attention to:

• The **flapper** (rubber piece at the bottom)
• The **fill valve** (where water enters)
• The **float** (controls water level)
1. **Check the flapper seal.**

If water slowly trickles into the bowl when the toilet is “off,” the flapper may not be sealing.

• Turn off the water supply valve (behind or under the toilet).
• Flush to empty most of the water.
• Inspect the flapper: is it warped, cracked, or covered in buildup?
• Wipe the seat where it rests; replace the flapper if it’s damaged.
1. **Replace the flapper (if needed).**
2. Disconnect the flapper chain from the flush handle.
3. Unhook the sides from the overflow tube.
4. Clip the new flapper onto the overflow tube.
5. Attach the chain so it has a little slack—too tight and it leaks, too loose and it won’t flush.
6. **Adjust the water level.**

If water flows into the overflow tube, the tank is overfilling.

• For float-cup valves: turn the adjustment screw on top to lower the float.
• For ball floats: gently bend the float arm down.

Aim for the water level to sit about 1 inch below the top of the overflow tube.

1. **Test for leaks.**
• Turn water back on.
• Let the tank fill and listen—no hissing or trickling should be heard.
• If it still runs, the **fill valve** may be worn and needs replacing (new ones come with clear instructions on the package).

2. Fix a Door That Won’t Latch or Closes by Itself

A door that swings open or doesn’t latch is usually a problem of alignment, not a sign you need a new door.

What You’ll Need

• Phillips screwdriver
• Wood toothpicks or wood filler
• Hammer (optional)
• Utility knife (optional)
• Chisel (optional)

Step-by-Step

1. **Check the hinges first.**

Open the door halfway and gently lift up on the handle.

• If the door moves up and down, the hinge screws may be loose.
• Tighten all hinge screws with a screwdriver.
1. **Repair stripped hinge screw holes.**

If screws keep spinning and won’t tighten:

• Remove the loose screw.
• Insert a couple of wood toothpicks coated in wood glue into the hole.
• Snap them off flush, then reinsert the screw and tighten.
1. **Fix a door that closes by itself.**
2. Remove the top hinge pin.
3. Lay it on a hard surface and gently tap the center with a hammer to bend it slightly.
4. Reinsert the pin—this slight bend creates friction and helps keep the door in place.
5. **Align the latch and strike plate.**

If the door won’t latch:

• Close the door slowly and see where the latch hits the strike plate.
• If it hits too high or low, you may need to move the strike plate slightly.
1. **Adjust the strike plate (small shifts).**
2. Loosen the screws on the strike plate.
3. Shift it slightly in the direction needed (up, down, in, or out).
4. Tighten and test. Repeat until the latch catches smoothly.
5. **Reposition the strike plate (larger misalignment).**
6. If it’s way off, remove the plate completely.
7. Mark the new location where the latch meets the frame.
8. Chisel a shallow outline so the plate sits flush.
9. Drill new pilot holes, screw the plate in place, and fill the old holes with wood filler or toothpicks and glue.

3. Clear a Slow Draining Bathroom Sink Without Harsh Chemicals

A slow sink is usually caused by hair and soap scum in the drain trap or stopper, not a deep plumbing issue.

What You’ll Need

• Bucket
• Old toothbrush
• Rubber gloves
• Small plastic drain snake (optional)
• Adjustable wrench (optional)
• Rags or paper towels

Step-by-Step

1. **Check the stopper.**
• Remove the sink stopper if it pulls straight out.
• Clean off hair and gunk with an old toothbrush.
• Rinse, replace, and test the drain.
• **Remove a lift-rod style stopper.**

If it doesn’t pull straight out:

1. **Clean the stopper thoroughly.**
2. Scrub off hair, soap scum, and residue.
3. Rinse well before reinstalling.
4. **Use a drain snake (if still slow).**
5. Insert a small plastic drain snake into the drain.
6. Push down gently, then pull up to remove clogs.
7. Repeat until the snake comes up relatively clean.
8. **Reassemble and test.**
9. Reinsert the stopper from above.
10. From below, slide the horizontal rod back into the hole on the stopper stem and tighten the retaining nut.
11. Turn on the water and confirm smooth draining.
12. **Prevent future clogs.**
13. Use a mesh drain cover to catch hair.
14. Once a week, flush with hot water and a little dish soap to break up buildup (avoid frequent use of harsh chemical drain cleaners, which can damage pipes over time).

4. Patch a Small Hole in Drywall So It Blends In

Small holes from screws, nails, or doorknobs can make walls look rough—but they’re simple to repair with basic materials.

What You’ll Need

• Spackle or lightweight joint compound
• Putty knife
• Sanding sponge or fine-grit sandpaper (120–220 grit)
• Damp cloth
• Primer and touch-up paint

Step-by-Step

1. **Prepare the area.**
• Wipe around the hole with a damp cloth to remove dust.
• For holes up to about the size of a quarter, simple spackle is enough.
• **Apply spackle.**
• Scoop a small amount of spackle onto the putty knife.
• Press it firmly into the hole, then pull the knife across at a slight angle.
• Scrape off excess so the patch is level or slightly raised above the wall.
• **Let it dry fully.**
• Check the product label for drying time (usually 30 minutes to a few hours).
• Avoid rushing this step; sanding too early tears the surface.
• **Sand smooth.**
• Lightly sand the patched area until it’s smooth and flush with the wall.
• Feather the edges so there’s no obvious ridge.
• **Prime the patch.**
• Apply a small amount of primer over the repaired spot.
• This prevents the patch from “flashing” (looking different) under paint.
• **Paint to match.**
• Once primer is dry, apply touch-up paint with a small brush or roller.
• Blend slightly beyond the patched area so it merges with the surrounding wall.
• **For larger holes (golf ball size and up).**
• Use a self-adhesive drywall patch.
• Apply joint compound over the mesh, feathering the edges.
• Let dry, sand, recoat if needed, then prime and paint as above.

5. Stop a Leaky Kitchen Faucet at the Handle or Spout

A dripping faucet is annoying and wastes water, but many leaks can be fixed by replacing a worn cartridge or washer.

What You’ll Need

• Adjustable wrench
• Phillips and flathead screwdrivers
• Allen (hex) wrench set (for some handles)
• Replacement cartridge or O-rings (check brand/model)
• Plumber’s grease (optional)
• Towel or rag

Step-by-Step

1. **Turn off the water supply.**
• Look under the sink for two shutoff valves (hot and cold).
• Turn them clockwise to close.
• Open the faucet to relieve pressure and confirm water is off.
• **Identify your faucet type.**

Most modern kitchen faucets use a cartridge. Older ones might be compression (separate hot and cold handles you tighten down firmly).

1. **Remove the handle.**
2. Pry off any decorative cap with a flathead screwdriver.
3. Use a Phillips screwdriver or Allen wrench to remove the handle screw.
4. Lift off the handle to expose the cartridge or internal parts.
5. **Inspect and remove the cartridge.**
6. Take a photo before disassembly so you can reassemble correctly.
7. Use an adjustable wrench or pliers to loosen the retaining nut or clip.
8. Pull out the cartridge straight up. If it’s sticky, wiggle gently—don’t force it sideways.
9. **Replace worn parts.**
10. Take the old cartridge to a hardware store to find an exact match.
11. If the faucet uses O-rings or rubber seals, inspect for cracks or flattening and replace as needed.
12. Apply a thin layer of plumber’s grease to new O-rings to help them seat and seal.
13. **Reassemble the faucet.**
14. Insert the new cartridge in the same orientation as the old one (use your photo).
15. Reinstall the retaining nut or clip and tighten snugly (do not overtighten).
16. Reattach the handle, screw, and decorative cap.
17. **Turn water back on and test.**
18. Slowly open the shutoff valves.
19. Turn the faucet on and off, check for drips at the spout and around the base.
20. If it still leaks, double-check that the cartridge is fully seated and the retaining nut is tight.
