Ever since owning this house, I've had pretty consistent water pressure issues: sprinkler system heads often don't come up, showers are severely impacted if any other tap is open, things like that.

I've been recently wondering if the elbow in the plumbing for my main water line could be playing any role in this. Incoming water line - shutoff - pressure regulating valve - elbow - water meter - feed the house.

Could anyone offer an opinion on this and if the elbow could be playing a role in these issues? Thanks in advance!

what about what elbow ? threaded 90 on top of reg ? I doubt its an issue but if its gal and rusted inside reduced diametor ok change it. of cource check pressure on both sides of regulator someone messed with regulator I see and turned it in to increase pressure. bad regulator is a posibility

That pressure reducing valve has a screen under the lower big nut bottom and has a gasket. Water meter and prv both have pressure drops need to know the gpm chart might bein the install manual or manufacturer web site. Clock the meter.

Thanks for the feedback. This is how it was plumbed when I bought the house, and agree that I'd rather have irrigation unregulated and only regulate pressure to the house. That would probably be a larger renovation to this, but not out of the question (but not DIY-able for me, not a plumber :)).

no other comment from you have you tried anything to figure it out ? it never worked right since you been there?
One not so long shot could be is there a curb stop at street that could be checked to see if fully open. another thing is a flow test see how much water comes through the meter or even remove it and see how much will flow into bucket by using a stop watch in gallons per minute real easy stuff to do it takes time though

I will take some water pressure readings to see where I'm at inside the house. I can't easily test water pressure before and after the PRV without some work I'm not totally comfortable with.

inside the house is good. you gotta do something to get to the bottom of it. Or are you just collecting info to steer a plumber in the right direction? wild guess bad regulator when I say wild guess if its 20 years old Essentialy they are bad just my experiance I verify it though
