Redirected copper pipe now no water pressure?

We have recently had to redirect some copper pipe that runs up the side of our house and goes to both bathroom and kitchen but since doing this there is suddenly no water pressure in the shower or in the kitchen sink. We added in 3 elbow joints that were not previously there. Could this be the problem?

The added length or ells should not significantly reduce pressure. Just like adding a 100 foot hose to outside hose bib.

Did you have good pressure before the change? What size pipe did you use? usually 3/4 is used for the main run and 1/2 for branching to a particular appliance. Did you remove the shower and faucet heads and flush the pipes? Are there flow restrictors in the shower head or faucet?

First check the strainers & aerators at each fixture to make sure they are not clogged. Sometimes working on the piping can knock scale and mineral deposits free that get flushed down the line and caught in the fixtures.

Are there places where the pressure is still good? Is the bathroom sink working fine, but connected to that same system?

Possible that you allowed too much solder in the pipes, creating a large metallic clog. But that would be the case only if everything on your "new" line is affected.

Not sure if this is possible, but I think I have heard of it happening. Is there any way a shutoff valve that you turned off to do the soldering has failed, and really isnít opening back up when you turn the handle? Guess that would be a real long shot.

I'd be willing to bet this is the issue. It's recommended to always run the bathtub first after doing plumbing work to clear out the gunk, then take off each aerator when opening the faucets for the first time. It's amazing how much gunk you stir up in the pipes when doing plumbing work.
