Have just fitted a santon unvented cylinder,mi's state 15mm supply is allowed provided recommended pressure and flowrate can be achieved,which i think with your readings it would be.
thanks,somebody has bought this syphonic toilet and wants me to fit it but doesnt want overflow showing,hence my question,think i'll advise against fitting it as seems like it could be trouble!
i have to replace a bypass rad in a bathroom,i say its a bypass rad as there are no valves but am prepared to be corrected!the rad to be replaced is a double panel 900mm high by 800mm wide,could i replace with a smaller rad or has it been sized this way,seems very big for a room with just a bath...
