Moved some pipes around in basement in preperation for it to be finished. I think I actually went down in total length of pipe by about 15-20'. However I added about 9 new elbows to the system (3/4"). I did not increase the size of any of the lines.
So that's the background, here's the problem. When I turn on a fixture upstairs, at first I get high flow/pressure but then it drops to pretty low after about 5-10 seconds.
On a couple of spots I had to use the bread trick to sweat the pipe, I'm wondering if it still might be in the lines somewhere, like maybe in my water softener. I say because here's something thats crazy. A supply line to a sink at the beginging of the system is plugged up. I think maybe when I turned on the kitchen sink (mixing valve?) the bread traveled into the faucet and out the hot supply (thus going backwards through the system? I know this sounds crazy but when I was plumbing I had the hot line open but cold was working. When I turned on the cold it would come out the faucet but would also come out the open hot line a little. I know for sure the hot/cold supply lines are hooked up correctly.
I checked the pressure at the faucet outside and I have 49 psi.
What should I do, Is there bread in the system somewhere. Is it a friction issue? Can I try turning up the pressure without damaging my pipes? Will that even help? Or do I need to redo the whole thing with less elbows? Help, I'm in it so deep here.
