drinking water filter location/seperate valve connection to dishwasher
Remodeling our kitchen room is totally gutted. Have a new utility room, 3.5′ wide by 5′ deep with 24″ door that opens to the outside. This room will contain a tankless water heater, phone and cable tv box. I wanted to also mount a carbon filter in the utility room and run a 1/4″ copper tube to 48″ built-in subzero fridge about 10 feet away, plus tee it off to faucet atop sink for drinking water, sink is about 7 feet from where filter would be. So, a plumber is telling me to put the filter under the kitchen sink, I’d prefer putting in utility room. He says you dont want all that tubing (have raised foudation)under the house. So, what do you think, mount filter under the sink or in utility room? Also, what type of filter systems do you prefer?
Also, for the 1/2 ” copper pipe that will feed my kitchen sink, I stubbed it out now with 6″ stub that is capped for pressure testing. He wants to cut the riser and add another stub with it’s own valve that would feed the nearby dishwasher. Can’t I just use the one stub with one valve that feeds both the hose that goes to the sink and another output on the same valve that goes to the dishwasher? Is two seperate valves on two stubs really the way to go ? or is the guy just trying to take my cash.
thanks

I don't know to what extent having the tubing in the crawl would be an issue, but you want the drinking water line connected to the sink line and as short as possible. This is so you can run water through the sink until cold, then draw water from the filter. If the line to the filter is remote then you'll never get cold water from the filter.
The fridge filter is probably not as big an issue.
I'd recommend two separate filters, since they don't last that long. I'm partial to the GE bayonet-mount units even though they're fairly expensive, since they're so easy to change (no need to shut off the water). But still be sure to install quarter-turn shutoff valves on the feeds.
DanH-thanks for the reply, that's a good point about the temp of the water, would have to clear the entire line to get to the cold water, although I'm in So. CA and crawl space stays fairly cool even in summer. . Maybe filter under the sink aint that bad afterall, not like your under there everyday. You know anything about Bodyglove carbon filters, local plumbing place says they are good and for $400 they better be.Do you buy the GE filter on the web?
I looked at the BodyGlove and they look to be awfully expensive for little more function than other filters.
The GE's are available online or at HD. What they advertise are two-cartridge models, but there's an available single-cartridge model (GXLRQ -- designed for a fridge) that is cheaper to maintain and I suspect just about as good.
Shutoffs
Do use separate qtr turn shutoffs for anything you are supplying-faucets/dishwasher etc. Need to service something, shut it off-while keeping others open. Only way to go, can never have enough isolated valves. Shutting the house down (or parts) is a pain in the rear when only one thing needs turned off.
