Hi,
I'm looking for recommendations on new shower/bath valves (part behind the wall that mixes hot and cold water) that have excellent water temperature stability when experiencing a pressure differential. Anything on the market right now is anti-scald and safe, but I can't find any reviews that detail behavior when other common bathroom events occur that affect water flow: flush toilet, sink on/off, etc.
I have two bathrooms that are fed from a single 3/4" hot and 3/4" cold water feed. Right now, both shower valves are dumb feeds without any anti-scald. I think new thermostatic valves are the way to go, but cross-comparing brands has proven difficult (Delta, Speakman, Moen, Kohler, Grohe, Hansgrohe, …). The sales literature only lists the basic temperature stability (and lots of shiny control levers), but not response times or damping curves to consider the carry-through during shock events. Grohe gets close with a sales cartoon of how their product performs (image attached), but it seems related to safety performance than comfort.
Does anyone have a similar plumbing arrangement and what do you think of their shower valve performance when other people are using trunked fixtures? Are the electronic units any better?
