I've attached a picture of my question. You can see that the incoming water piping size to my house is 1.5". You see where the relief valve, expansion tank and transducer are. When they reduced the 1.5" pipe to 3/4" pipe. How much volume am I losing from that reduction? I know its such a tiny run, but you can see where the bladder is, having to go through .75" reduction and then having the water have to turn from the cross, and go into the pipe. Would upgrading it all to 1.5" help with supplying volume to my bladder any faster? Also, you can see in the picture. Would it be a better idea to put my bladder on top of the cross, and put the transducer where my bladder is? Could upgrading the 3/4" piping to 1.5" and moving the bladder on top of the cross help? The reason when I ask is, because when I have my irrigation on and there is a big demand for instant water. My bladder can't fill fast enough because of the pressure drop and it causes my bladder to slam down and cause a water hammer in my house. I know the solution to that problem is, lower the demand on the irrigation ( which I can't do at all ) or increase the pump size. But my question still stands, would moving the bladder to the top of the cross, and moving my transducer to the bladders original location, and increasing the piping size help with filling the tank faster than its currently being filled when theres a pressure drop? Its a VFD system, not a CVS. I understand the pressure tank is a shock absorber. According to the manufacturer. a 40-45GPM system should be using a 9 gallon tank. The one I have is 4.4 gallon. It definitely need more shock absorber. Do you think upgrading to a 10.3 gallon tank, and increasing my piping size to the bladder help my problem? [ATTACH]94713[/ATTACH]

The top is the tub drain, and the lower part is the sink drain. They will prob be moved to a new spot in the resized bathroom. Would you take out everything where it meets the main stack and redo it with pvc? [IMG][/IMG]
