    I have yet to take the middleman out of the equation

    Grohe Ladylux Faucet
    Tapmaster

    The *control* for the faucet is always on as the tapmaster controls the water outout.
    With the ladylux on hot water, NO issues,
    On mixed, NO issues

    On cold only, I get a very slow flow.
    Just simply moving the faucet handle to off and then back on, I get normal water pressure.
    Once I release the *tapmaster pedal* - aka, no more water flow to faucet, and then press the pedal for cold water - Same symptoms.
    If I simply move the handle on the faucet to on and then off, it's all good

    Sounds like a check valve sticking.

    Would it be the tapmaster or the faucet. Assume if I keep the pedal on, and just simply move the faucet from on to off to on, the faucet get's full flow

    My basement bathroom basin sometimes has low hot water flow. I think it is when the kitchen hot water is being used. Ideas?

    Just a THUMBS up to Tapmaster.
    Send me 2 new valves out 2nd day from Canada to the States.
    Couldn't ask for better customer service turnaround and they deserve a public praise
