Hello, We have been faithful TOH watchers since the days of Bob Vila. We have a problem and hope you can help us. We have very poor water pressure to the bathtub and shower. My boiler tech told me that the pipe off the boiler leaves the boiler as 3/4" then goes to 1/2" as it snakes to the tub. Can the pipe be cut and joined with 3/4 " to increase the water pressure to the tub and shower? We feel like we're being sprinkled on when we shower and it takes 45 minutes for the tub to fill. We'd appreciate your help. If this can be done, can Pex be joined to copper piping to increase size?
Thanks, Bob and Sue Montmeny, Springfield, MA
