Hi Guys, with the forums help I installed a Watts lf25aub-z3 pressure reducing valve and an expansion tank. Reduced my house pressure from 95-100 (city) to ~55. My question is about "normal" pressure fall offs? In my original post someone included a Watts chart, but i'm not sure if I'm understanding it. I just want to know if the pressure drops I'm seeing with water running is okay or if this valve is faulty and I need to return it for another?
Static pressure is set to around 55 psi. If I turn both the hot and cold sink faucets on in the 1st floor bathroom the pressure drops to around 45 psi. Its a new faucet so I know it has a 1.5 gpm max flow. If I turn on the shower, which has a max 2.0 gpm, it drops to around 43. If I use the tub spout, which I believe is unrestricted, it drops down to 38 psi.

If i'm reading this chart in the link above correctly a 1.5 gpm flow should have barely any pressure fall off
Do these drops register as normal or do I need to return this?
thanks Jay
