In process of refitting bathroom. Cold water to bathroom is gravity fed from tank in loft. I assume same tank refills the hot water cylinder which is heated by an immersion heater (yes, an immersion). Hot water then runs to from cylinder to bathroom. We are planning a Bristan bath/shower mixer in the bathroom (the usual flexihose from tap to shower). bath shower mixer is two taps plus hose to shower type. The basin will be fed by a Bristan mixer tap. Flow of both hot and cold is to bath first, then basin, then cold to toilet feed.
I only thought I would need check valves if the system was unbalanced with mains fed cold and cylinder fed hot. Right? Wrong? If needed, which check valves???? and where?? Not much space to fit them in.
