Bulge in Washing Machine Hose?
What it Means: The hose is ready to burst.
A bulging washing machine hose is an emergency. It may burst next year, next week or right now. But it will fail and it won’t just leak — it will gush. In just a few minutes, it can do thousands of dollars in damage. Check out this l ist of stuff to keep on hand in case of a major (or minor) emergency .

How to Fix a Bulge in a Washing Machine Hose
What to Do: Replace rubber hoses with braided stainless steel.
Immediately turn off the valves connected to the hoses. Before your next load of laundry, you’ll need to replace the hoses. Buy new braided steel hoses and also invest in a pressure gauge that hooks onto a spigot or laundry room faucet. Your rubber hoses may have bulged because your water pressure was too high . It shouldn’t be more than 80 psi. If it is, install a pressure-reducing valve (PRV) before you damage other appliances and fixtures in your house. If you already have a PRV, it may be set too high or due for replacement. Here are 10 silent signs your house has a major plumbing problem .

Stains Around a Bath Fan?
What it Means: Condensation is forming inside the duct.
The stain could be caused by a roof leak but condensation inside the duct is the most likely cause according to ??? Staltzman, a second-generation home inspector with Structure Tech in Minnesota. If you live in a cold climate, there’s a good chance that the warm, moist air from the bathroom is condensing inside the duct and the water is seeping back down into the fan housing. It’s soaking the drywall around the fan and may be ruining your fan motor or even the framing components in your attic.

How to Fix Stains Around a Bath Fan
What to Do: Investigate, insulate and run the fan longer.
Start by checking the damper inside the fan housing and the one on the vent outside. Vents are usually on walls or roofs, but sometimes they’re in the soffits. A stuck damper can lead to heavy condensation.
A bath fan duct that’s not insulated (or poorly insulated) gets really cold in the attic. A cold duct filled with warm moist air is a recipe for condensation. On exceptionally cold days, that condensed water freezes and then drips back down when the temperature rises.
Even insulated ducts get cold enough for condensation to form when the fan first starts up. If a fan is run long enough, the duct will warm up and dry out. Consider replacing the wall switch with a timer switch, which will run the fan for a set period of time. Condensation forms in ducts (left). Warm air condenses on the inside of a cold duct and the water runs back down into the house. Insulate the duct (right). You could wrap the existing duct in insulation, but it’s usually easier to replace it with a duct pre-wrapped in an insulated jacket. Here are 15 silent signs that your roof is failing .

Efflorescence on Chimney Brick?
What it Means: Too much moisture inside the chimney.
Efflorescence is the white material that appears on brick. It occurs when moisture moves through masonry . That moisture picks up minerals and leaves them behind in the form of tiny crystals. The minerals themselves do no harm, and a small amount of efflorescence is common.
But heavy efflorescence on your chimney is a cause for concern. It’s a sign of moisture inside the chimney—and when that moisture freezes, it can slowly wreck the chimney from the inside out. Even more alarming, your flue liner could be cracked or broken, and deadly combustion gases from your furnace, fireplace or water heater may be leaking into your home. Be sure to follow these 13 steps on how to use a fireplace safely .

How to Fix Efflorescence on Chimney Brick
What to do: Fix the crown or call an expert.
Immediately have your chimney inspected by a licensed chimney sweep certified by the Chimney Safety Institute of America (CSIA). Learn more about chimney maintenance for your home.
Cracks in the crown allow water in (top left). Water that gets inside the chimney through cracks in the crown can cause efflorescence and damage the bricks. Seal the crown (bottom). Small cracks in the crown can be sealed with an elastomeric masonry sealer, but a crumbling crown will have to be replaced. Smear on the sealant by hand, then smooth it with a brush. Find a crack?

Melted Grommets on a Water Heater?
What it Means: Deadly gases may be entering your home.
Exhaust from a gas water heater is supposed to flow through a duct and out of the house. But sometimes, exhaust doesn’t flow up and out. Instead, it “backdrafts,” spilling deadly carbon monoxide into the air you breathe . One sign of backdrafting is damaged plastic grommets on top of the water heater, melted by the hot exhaust. This shows that your water heater has backdrafted badly on at least one occasion—and you must take action.

How to Fix Melted Grommets on a Water Heater
What to Do: Get Carbon Monoxide alarms.
Sometimes, the cause of backdrafting is obvious: A vent pipe may be disconnected from a vent hood, for example, or a vent may slope downward. But even a properly installed vent might occasionally backdraft because of high winds or other unusual circumstances. So the surest way to protect your family is to install carbon monoxide alarms. If you don’t have CO alarms in your house, go get them today. Learn how and where to install carbon monoxide detectors correctly to make sure you stay safe.
Install one on every level, outside sleeping areas, and within 5 ft. to 20 ft. of any sources of CO, such as water heaters, furnaces and fireplaces. If an alarm ever goes off, get out of the house immediately and call the HVAC repair service to correct the problem. The symptoms of CO poisoning are dizziness, headaches and vomiting. If anyone in the house is experiencing these symptoms, leave the house and call the fire department.
Test for proper drafting (top left). Close all the windows and doors and turn on all the bath and kitchen fans. That creates a worst-case scenario for backdrafting. Run some hot water and light an incense stick and see if the smoke is drawn up the vent. Bad vents cause backdrafting . Water heater vents need to slope upward at least 1/4 in. per foot. The installer responsible for this down-sloping vent apparently didn’t know that hot gases rise.
Carbon monoxide alarms save lives (bottom). Every home with an attached garage, fireplace or gas appliances should have carbon monoxide alarms. If you already have them, be sure to test and maintain them according to the manufacturer’s instructions. Here’s how to prevent carbon monoxide poisoning in your home .

Decking Directly Under the Door?
What it Means: Rot could be wrecking your house.
Decks that are built right up to the bottom of a door often mean trouble. Rainwater splashes off the deck up onto the door . That much water is hard to keep out. Even if the flashing holds up, water may eventually find its way through the door components. This can ruin the siding, door and interior flooring, or worse, destroy the rim joist and other framing components both inside and outside your home. Here’s how to repair rotted wood .

How to Fix Decking Under a Door
What to Do: Divert the water away.
Diverting the water with gutters will help . However, the bottom line is that as long as the deck boards are up tight under the door, there’s a chance of water infiltration. If you plan to build a deck, install it about 4 in. below the door threshold. And never let snow pile up against the door. Here are our expert tips for building a deck .
Interior damage (top left). Splashing rainwater can work its way through the door and leak into the house, damaging the rim joist below. Installing gutters will help (top right). If there’s an overhang above the door, install gutters to divert the water that pours off the roof. Read more about, installing gutters on your home. Exterior damage (bottom). Splashing rainwater can work its way through the door and leak into the house, damaging the rim joist below.
