I was doing some work to the shower in my hall bath, just replacing the shower/tub valve. I had the main water supply valve in my house turned off for an hour or so. After I had it hooked back up, my girlfriend went to take a shower in the other bathroom so I turned the water supply valve back on. She took a shower, and when she got out, shen told me that the valve must not be open all the way because water pressure was about half of what it is normally. I went and checked the valve and tried it in a few different positions with the same results. Not sure what the name of the valve is, but it's a circle handle that takes a few full turns to open it completely. The water pressure problem is the same for hot and cold water. I tried water in my kitchen sink, and the pressure outside on the front house with the same result. One thing I noticed was that outside on the hose, there is decent pressure when I first turn it on, but after about 5 seconds, you can watch the distance the hose sprays cut in half. I also shutoff the cold water inlet to the hot water heater and then checked cold water pressure throughout the house and it was still low. The only thing I can think of right now is that my shutoff valve has gone bad and is not fully opening. I am remodeling that bathroom and have not yet used the new plumbing I installed. I'm sure it's full of air. Would this somehow cause low pressure throughout the house? Thanks in advance for any help.
