Showerheads – Weak or changing water pressure usually points to a mineral buildup in the showerhead. Clean the outlet holes with a pin or unscrew the faceplate and soak it overnight in vinegar. Scrub it clean before replacing it on the showerhead.
Scalding Tap Water - Thousands of people are scalded by tap water every year. The Gas Appliance Manufacturers Association recommends that the full-on hot water temperature at the faucet be set between 120° and 125° F
Garbage Disposal - Use cold water when the disposal is operating. You can clean your disposal by grinding ice cubes. When you disposal needs a little freshening, just grind some lemon peels. Of course, you should read your maintenance manual.
Water Moisture In The Home – Make sure that vents (with a ventilating fan) are installed in your kitchen and baths. These rooms can produce a lot of moisture. Ventilating fans are great but will be of no use if they are not turned on! So make sure that you use them!
Mildew – You can help to avoid mildew problems with these preventative actions. Ventilate basements or run dehumidifiers to dry the air, walls and furnishings. Don’t hang wet clothes in your closets. Keep your showers and tubs clean of soap-scum so that they dry quicker. Air-out your bathroom cabinets and kitchen sink cabinet often.
Pipe Insulation - Insulate those pipes before it gets cold! When temperatures are at or below freezing, running a steady drop of hot and cold water from your faucets may keep your pipes from freezing. If your pipes are not insulated, they can freeze even with a small flow of water. So, insulate those pipes! But beware; insulated pipes can freeze when there is no water movement to keep the pipes warm.
Roots - Roots can be a big problem. They can grow into the joints of the pipes. A little "root-x" flushed down the toilet can reduce the growth of roots in your pipes. It needs to sit in the pipes overnight, so do it before bed.
