You don’t turn on the fan when you shower
When mold moves into your bathroom, it can colonize in the crevices, the caulking, and even grow on your bathroom ceiling. Running the exhaust fan during and after a shower or hot bath to remove excess humidity. If that doesn’t give it the heave-ho, water could be getting behind the tiles or tub, or there may be a leak behind the wall. Fight mold with antimicrobial tea tree oil; add 15 to 20 drops to a spray bottle filled with water, and use it to spray down shower tiles after use. Also, be sure to shake out the shower curtain post-shower and only close it halfway to let air circulate.
You’ve been ignoring that hairball in your drain
If your shower drain is on slow-mo, hair could be the culprit. It collects and combines with soap residue and can turn into a rat’s nest–size blockage. Prevent the problem in the first place by picking up a hairguard at the hardware or dollar store. If the clog is close enough to the top, try pulling it out with tweezers. Otherwise, use a wire clothes hanger with a ‘J’ hook at the end. Stick it into the drain as far as you can, turn it a few times and slowly pull it out. And brace yourself—what comes out isn’t going to be pretty.
Your water is hard
That white film on your showerhead and plumbing fixtures means you have hard water. Hard water, which comes into contact with rocks or soil, has higher levels of essential minerals like calcium and magnesium than soft water does. Soft water is better for plumbing fixtures simply because minerals can actually damage plumbing appliances over the long haul. Soft water also means cleaner clothes and dishes with less detergent (bonus for the environment!), while hard water wins for taste and gives your body much-needed minerals. So how do you know if you have hard water? If your shower curtain is scum-free, your water’s likely soft.
Your leak is wasting serious water
There’s one quick plumbing fix everyone should know: how to turn off the main water valve. Your main water valve is usually in the basement or inside a closet, and in warmer climates, it’s often on an outside wall or inside the meter box near the curb. Just don’t save the search party for an emergency. If it takes a special tool, like a meter key, know where it is and how to use it. Stick the meter key into the box’s key slot, turn it counterclockwise, and lift off the lid. Locate the valve lever inside and, using a T bar or wrench, turn it clockwise to shut the water off.
