Hello, I have recently replaced the pipes in my VERY small home. I cut the line just after the water meter and line that runs to the yard(outside, i needed this to have atleast some water while i did this project. As soon as it was cut I capped it was going to be a slow project (water to house is off). Immediately i noticed the water pressure to the outdoor hose was reduce to maybe 1/4 of original strength. FIRST I checked to make sure i did not bust a line under the foundation, i did not. A few days later i got back to continuing the project, next I connected a copper line to the kitchen sink (maybe 10ft worth total). This went smooth, i turned on the line and everything worked. First thing I noticed was the kitchen sink was not flowing a full strength. Second I noticed that full pressure was back to the garden house, sprayed like a champ. A few weeks later I finally finished the lines to the one bathroom (about 10feet from the kitchen). I capped all my lines and connected the shower, I only have the cold water connected currently, i noticed there was almost no pressure coming out of the shower nozzle. It just dripped. I'll admit this could be for all sorts of reasons as it is used. My biggest concern is the water pressure to the hose dropped again, back to about 1/4 of original pressure. Currently kitchen sink runs at about 1 gallon 40 seconds. Question, is the water pressure to the sink / shower affected by not having the hot water connected? Question 2, I have no pressure reducer valve installed, can this not being in stalled actually reduce my water pressure? Like maybe the meter can sense it and reduces the output? Thanks in advance.
