Default Elbow Placement

I'm installing a new water softener. I have a very small area to tie in to the water line between the pressure regulator and the T that goes to the water heater. The pipes are in the wall and I need to run them out of the wall. This will require a lot of elbows. There is one area I'm going to have to use 3 elbows in about 10 in of line or less. I'm using 3/4 in PVC. Is there a code, regulation, or rule of thumb about how many elbows you can use in a certain amount of space?

No, excessive elbows will cause turbulant flow and age the pipe faster also risking the pipes being loud when in use but there are no code limitations, use 45's where you can to reduce flow restriction.

Thanks. Here's what I'm working with. The water supply comes up from the bottom right (behind drywall), comes out of the wall, goes through a shut off valve and the pressure regulator (just below were picture cuts off), reenters the wall, turns left through a 2X4 and Ts. The up T is to the water heater, the down is the main cold water supply. Any advice on how to route the pipes for the softener?

PVC is not allowed inside a building. But it looks like you have CPVC you may have thought it was PVC.

If your water pressure is good I don't think I would be to concerned.

R U saying PVC SCH 80 is not allowed to be used in indoor (pressure tank to filter system - no hot water introduced - CPCV from after filters) plumbing?

I a$$-u-med that when he compared CPVC usage also.

PVC is allowed within a filtering system, correct? CPVC afterwards?

In my area PVC is not allowed inside the home. If the filter system is out side it is allowed.
