The image is a "timeless" ceramic basin mixer. We cannot get water to flow through the hot side of the mixer. It is fed by a Brittony water heater so the pressure is slightly less than mains but the design of the tap is such that the mixer part of the tap is connectected to the hot (and cold) feeds by a flexi connector that by design is severely kinked double in order to connect the hot feed to the central part of the tap.
The tap is designed at 0.2 bar and the cold flows through ok however the flexi design means the hot is so restricted it only trickles through.
Has any one come across this type of problem before ?
