I am trying to increase the water volume to my house. I currently have a 5/8 water meter to a 3/4 main that runs about 30 feet to the prv which ive replaced with a watts 223 and then goes to rinnai instant heaters. I cannot upsize the main or meter due to ridiculous charges by our local municipalities. H2O pressure from the street is 125 psi. Do you think I could increase flow by increasing to 1 inch as the main enters the house upstream of the prv, then going with a watts 223 1 inch prv and 1 inch pipe to the rinnais, theen i could plumb 1 inch pipes to the risers going upstairs. I am currently only able to get about 7 gpm out of our master shower and I plumbed 3/4 all the way to the drop ear elbows through a hansgrohe volume control and 3/4 thermo mixer, it just seems like we should be getting much more water flow. Also we got about 10gpm before the rinnais were installed and just had a 50 gal h2o water heater.
