Out of the pressure tank is 1" then past the pressure gauge is 1/2" throughout the house to all of the faucets. The tank pressure is 40psi. The hot water is the same. 1/2" throughout from the tank. All faucets have very low pressure. Shouldn't the line past the pressure gauge be at least 3/4" and then 1/2" as you tee to each faucet?
The total length from the pressure tank to the furthest faucet is about 25-30 feet.
it was replaced with CPVC by someone who wasn't sure what he was doing, thinking that 1/2" would suffice.

What are the pipes in the rest of your home? Copper,plastic or galvanized? My 55 year old home was piped in 1/2" so I can sympathize wiuth your problem. Regards, tom

You don't really have a pressure problem, you have a volume problem due to under sized piping. You can get some relief by increasing your pump pressure to something higher, around 55 psi. This will increase your volume/pressure but may put a stain on a weak link somewhere in your homes plumbing

Ballengerb1 said it: you have volume problem. Your pipes are undersized. You should have at least 3/4 pipe with 1/2" branches. Yes, you can increase pressure but higher pressure in small pipes will create more friction making your pipes "noisy".
