    Installed our Moen faucet this weekend. Temporarily screwed in the faucet to test it out.

    It's a single handle (Posi-Temp) Moen Monticello.
    Feed: 3/4 Copper out of the water heater to 3/4 PEX. 3/4 Pex splits to 1/2 inch Pex going to the tub and 1/2 inch Pex to the sink.

    It seems like the flow out of the tub faucet isn't right. If it's on anything but full hot or barely on at all, the flow seems to not stay tight together but instead flatten out and separate.

    Is this normal, or is it usually a tighter, more column-like flow? If it's not normal, why? What can I do about it?
  2. Unthread the spout a few turns off the threaded nipple you installed.

    If it gets better, that means you sent that nipple too far into the spout and distorted the opening.


    High water pressure can cause that as well.

    Those spouts do not have stream regulators so it looks normal to me. At full flow the opening is filled so the water has less space to "splash" and at low flows there is not enough to splash.

    What is a stream regulator? Do most faucets have them?

    The diverter on the spout is causing that wide flow. It is very normal for that type of spout
  6. That's terrible.

    But then again, I'm assuming that is Moen's bottom line faucet? Cheapest?
