If your home’s water pressure doesn’t seem strong enough there are a number of possible causes. First, if the water pressure is only low in a few places, such as a shower head or faucet, it could caused by a clogged shower head or faucet aerator. Hard water can cause mineral deposits to build up over time, gradually reducing the flow of water. Soaking the shower head or faucet aerator in vinegar overnight will dissolve the buildup and get the water flowing again.
If low water pressure is a problem with all plumbing fixtures in the home, inside and outside, it could be a deteriorating plumbing system. If the home was built in the 1960s or 1970s it may have galvanized steel pipes. The galvanization was designed to prevent corrosion of the steel pipes. However, when the galvanization wears away rust can build up over time. The result is gradually reduced water pressure. To fix the problem, the pipes will need to be replaced. If the house was built in the 1980s or later, there is likely another issue with the plumbing. Start by checking that the main water shut-off valve is fully open. If the water was turned off recently for plumbing work, it may not have been reopened completely.
Perform a Water Pressure Testing
Water pressure can be tested using a pressure gauge on an outside water spigot. Water pressure is measured in pounds per square inch (PSI), and normal water pressure is typically between 30 and 80 PSI. If the reading is less than 40 psi, the city may be delivering water at too low a pressure. If the city can’t boost the pressure, one option is to install a water pressure booster system.
