shower is hot, bath is only warm, on-demand water heater

Author: lpazdiscgolf (AZ)

I have a Moen setup, I have an on-demand water heater in this remote bathroom. When I run the shower on full hot it comes out very hot, when I run it through the bath tub faucet it is hot to start with (after switching from shower) but then gets luke warm. I have determined that the flow rate through the shower allows the on-demand to keep up, but the flow rate is too high for the bath tub faucet. To fix this, I turned the Moen valve upside down so that when I turn it on slightly I can control the flow for hot out of the bath tub faucet. What I am wondering is if there is a way to restrict the flow from the bath tub faucet all the time so that I can run the controls the way they are supposed to be set. My work-around is slightly annoying.

Author: hj (AZ) Not with that, and many other valves also, since, unless it has a secondary flow "handle", they are designed to run "full flow" once they are turned on and the handle just controls the temperature.

Thanks for the reply
Author: lpazdiscgolf (AZ) Rats, that's what I thought, I guess my next best option is to just fill the bath tub with the shower head, could lay it on the ground in the tub. Thanks for the reply. Edited 1 times.
