PEX retro fit. How DO I attached PEX to something solid ?
Posted: Thu Apr 05, 2007 3:41 pm
Afternoon everyone.
I want to replace the galvanized pipes in my mid 1970's single wide with PEX.
I'm having a hard time understanding how to attach the PEX to the house.
I DO understand how to attach fittings, connectors and such to the PEX with slip rings.
But NOT how to make the PEX rigid so as to accept hose bibs or shut off vales like under the sink for the hot and cold feeds.
IE:
Under the kitchen sink there are two galvanized pipes protruding through the base of the cabinet.
One for hot water and one for cold.
They are rigid.
You know, solid.
If I grab either one, they don't move if I try and wiggle them.
That made it easy for me to attach shut off valves so I could change out the faucet without turning the water off to the entire house.
No comes my PEX pipe.
I hope to use the rolled flexible type.
I can drill a hole right next to each of the galvanized pipes under the sink and snake my PEX through.
But now it is flopping around.
In a retro fit situation like mine, where I hope not to open the walls, how to I attach the PEX to something before attaching my shut off vales to the PEX?
Another good example would be the fill valve for the toilet.
There is a rigid galvanized pipe sticking out of the wall right now.
And a shut off valve screwed onto the pipe.
I can probably snake a piece of PEX right next to it but once again it would be flopping around.
The shower and tub seem to be a lot easier.
I have a full length access panel that can be removed.
I'm guessing there is a PEX fitting of some sort, that can be attached to a 2 X 4 up around the shower head.
The PEX will run into the bottom of this fitting and the shower head "bar" will most probably screw into the other end of this fitting.
I really don't want to open the walls in order to attach the PEX to the studs inside of the walls.
I hope I am being clear.
Any ideas would be appreciated.
Is a puzzlement !
