Faucets and Showerheads
When it comes to your kitchen or bathroom sink faucet, you may want to begin by checking the small screens attached to the faucet. Minerals and rust often collect in these screens and can be cleaned with white vinegar or simply scrubbed with a toothbrush. Be sure to check your kitchen sink faucet sprayer as well because these also contain small screens.
If you are having difficulty with the water pressure in your dishwasher or washer, it may be because the water supply has to pass through shutoff valves before it can reach the appliance. To make sure your water pressure is optimal, be sure that all shutoff valves are fully open. Washing machines in particular are designed so that water is pulled through a filter. Be sure to clean the filters so your washing machine can fill quickly.
I also learned from the book that many old homes built before the 1960's are equipped with iron pipes. This means that your low water pressure problem may be due to mineral build-up within the pipes. A better alternative is copper or plastic.
