    Hello all,

    I am running a HW loop with dedicated return line. Pump is under my double vanity, last fixture on the loop. I now have concerns that the pump may starve the fixture...I was going to plumb it like this:

    Do you guys see any issue, or as I mentioned am I overthinking?

    Water will go to the path of least resistance under pressure. An open faucet will be vastly less pressure than the pump. There are others on this forum who have more technical knowledge about how pumps work via pressure differentials and may have opinions on what side of the pump to draw from.. but I doubt it makes a difference.

    I agree, that's my line of thinking. I planned it this way to simplify plumbing in my limited space, but I am wondering if I should T to the fixture then 90 to the pump. Should work as my faucet plumbing will be flexible.

    Needs a check valve in discharge of the pump. Swing checks have to be horizontal.

    Yes sir, but I was actually going to put it down at my HW tank, right above the T into the tank drain. I am a little limited in space at the pump/vanity.

    Any issue with that? Thanks for the reply.
