Replacing lines in old house


Going to be replacing the water lines in my father in laws house. Taking out the galvanized and replacing with PEX. Also moving the hot water heater (they had it in the bathroom....) to a back room.

It is a small house and all of the fixtures are on the way to the hot water heater from where the water comes into the house(it's a one floor house). I was planning on running 3/4 inch PEX all the way to the hot water heater for the cold line and since the faucets are 'on the way' will branch off with tees and use 1/2 inch to each faucet shut off valve. Would do the same with the hot water as well.

Anyone see any problem with this? Don't really have the room to use a manifold system. Main water line currently comes into the house in the bathroom so is going to be pretty tight just trying to get a water shut off valve in the house and accessible, but I will do it!!

Thanks in advance for the help.

Trunk & branch is the type you're doing and works really well. Sounds like you're headed in the right direction.

Depending on your code you'll also need to run 3/4 up to the toilet then branch off in 1/2 to lave shower etc,
