Kitchen sink supply with icemaker and drinking water tap

[bigb56]

I am getting ready to install my angle stops and supply lines under the sink. In the pic I have, from the left, hot, cold, ice. The ice line goes to a wall box behind the fridge. (I wanted a way to shut off the ice maker without pulling the fridge out). Trying to figure out the best way to do this. So far this is what I have come up with: Install a 2 way angle stop with a splitter like the one pictured below. Feed the faucet from one outlet, the ice maker from the second and the filter for the drinking spigot from the 3rd. (I will feed the ice maker with a supply line into another angle stop on the ice stub out). The fridge will have a built in filter.

Second idea is to use a 2 way angle stop, one outlet for the faucet, the second going into the drinking water filter, come out of the filter, install a splitter and one supply to the spigot and the second to the ice. This means the ice will get filtered twice and possibly extending the life
of the likely expensive built in fridge filter.

How would you do it?

PS the cabinet guy got carried away with the holes but I did find some oversized escutcheons.

Almost forgot, there will also be a recirc pump tee'd into the faucet supply lines

1. That is going to warm the water going to the fridge, assuming that the cold supply is doubling as the return.
2. You can edit your posts.

Thanks for the reply. I realize the pump will result in warm water on the cold side after it shuts off (it will be on a spring wound timer and only run for 1 minute since it also has thermostatic shutoff in the pump) as I have seen this in the bathroom, but I didn't think that occasional bit of warm water would affect the ice maker. The ice maker is approx 12 feet away through 1/2" PEX. It will also probably be rare that the ice maker will call for water at the same time the pump is in use, or shortly after. Do you think it's going to be a problem?

It will take a little extra time and energy to make ice or refrigerated water. Maybe that is not a problem.

There are people that think you should avoid drinking water that from the water heater. I don't know about the merits of their arguments.

It is more usual to put the bypass in the bathroom. Are you looking to get hotter water when filling the dishwasher, or are you thinking more of hand washing at the kitchen sink?

The house is plumbed in 3 separate branches so to get instant hot water at each branch it's taking 3 separate pumps. This one is for the kitchen and laundry, we have a washtub in the laundry. We don't like wasting water especially here in the desert.

You have the option to turn off/unplug the pump at the kitchen+laundry for a while, if you like.

If your pump was triggered by a button, rather than just temperature, you would still save water.

I have them all set up on 5 minute spring wound wall timers. They also have internal thermostats that shuts them off when the hot water arrives. They came with wireless buttons but the minimum on time was 1 hour which resulted in the pump starting up needlessly after the pipes cooled down until the hour was up. We only need them to bring the hot water initially for sink and shower then it's only a 10 minute or so use. So this way they run for approx 1 minute to bring the hot water to the fixture, thermostat shuts them off, then wall timer times out and prevents them from re-starting when we don't need them to.
