    Hey all,

    The 1/2 copper has shut off with 3/8 compression that navigates through the filter to the faucet. I would like 1/2 flow to the water hose spigot and 3/8 to the filter/faucet. I'm thinking both should have a shut off but am open to other recommendations. The water hose pipe has to rise 5" vertically and 50" horizontal from current shutoff, through a concrete block wall with plywood sheathing and vinyl siding. I'm interested in connection methods other than sweating copper pipe (I've never done it). Open to being schooled.

    You normally don't want to feed softened water to the outside spigot for irrigation.

    You normally don't want the outside spigot water to go through the cartridge filter. I think you know you are taking a shortcut.

    Add a "Add-A-Tee" to your existing supply valve. At this part you can use a "Add-A-Stop". This would give the a independent stop for the hose valve.

    no mention of a softener ? It is before inline fixture filter so that’s good.
    Construction of floor ? slab /crawlspace ?
    sounds like slab and block wall.
    So if no other way use add a tee fitting like above .

    You can also pick up a 1/2" Sharkbite tee and add shutoffs after that, keeping 3/8" for the filter and 1/2" to the hosebib.
