I am planning on doing a complex PEX install, and have decided to go with the 24 Port Brass PEX Crimp MANABLOC (9 Hot and 15 Cold). It has (2) 3/4 inlets (1) 3/4 outlet, and 1/2 outlet ports. I have a gas water heater closet in the middle of my one story home.
1) From what I have been told, the manifold "should" be within 10 feet of the Heater. Is that true? The reason why I ask, is that I don't really have a great place to put the manifold, so that it is readily accessible within 10 ft. of the heater, but I do have a great place like 30 ft. away. What are the drawbacks for placing it so far away?
2) Basic set-up: Do I have this right?
a) 3/4 line coming from water main to the 3/4 inlet of the manifold
b) 3/4 line (hot) coming from the water heater to the 3/4 inlet of the manifold
c) 3/4 line (cold) coming from the 3/4 outlet of the manifold to the water heater
d) 1/2 lines going to each fixture
3) In my sinks that do not have a cabinet, I will be using copper stubouts connected to an angle stop. The stubout must be connected to a stud. Correct?
4) My only access to the showers would be either through the tile, or from the side. Which would you do? I have two bathrooms. The master is a shower tub, and the guest is a shower stall. Behind the master is a recessed linnen cabinet, and behind the guest is a stucco wall in the garage. What would you do?
5) My biggest concern is replacing the piping for the water heater, it is in a closet in the middle of the house. I'm thinking that I will need to cut the galvanized riser with a sawzall, and then cut into the dry wall for the galvanized connections. I'm hoping that the galvanized isnt connected to a stud, and that when I cut the pipe, and remove the connections at the heater, I will just be able to pull it out. But, how will I be able to get back there to secure the Flex Copper Water Heater Connector to the pex?
I have far more questions, but I will leave it at that. Thanks for any advice you can provide.
