I have a new shower installation using a Grohe 34 902 mixing valve. It's a 3/4 " variant to supply two shower heads and lets you dial in the desired temperature.
What I've noticed is wild fluctuation of temperature after flushing the toilet. It's briefly colder than normal, then too hot, then back and forth with some variations in flow thrown in before stabalizing after about 30 seconds.
Does anyone have any experience to say whether this is normal or what could improve the situation if it's not? If it is normal, I'm pretty disappointed in Grohe.
