I've been having a problem with the water pressure in my house. My house had constant water pressure before I turned off the water to fix a leaky faucet. After turning the water back on the water pressure has become really low. Almost everywhere besides the fixed leaky faucet has low water pressure. It's especially noticeable when I tried to wash my clothes. For some reason barely any water comes out of my washer now even though it looks like there are separate lines running to my washer than to the rest of the house. The washer would start off a normal, with moderate water pressure but than spouts out barely any water. During that time I can hear a hissing noise coming from the pipe near the water meter. Also, I don't see any leaks coming from the area that making the hissing sound. Having the washer on causes no water to come out of any faucet too. Can anyone tell me what's causing the problem?
