have a kitchen mixer (Bristan I think) installed abt 5yrs ago. recently cold water flow has been reducing (hot fine 3bar!). This morning cold is only a trickle - hot still fine.....
(both h&c supplied by a 3bar pump, rest of house unaffected)
Had a quick google most 1/4 turn queries are about dripping etc - anyone had this low/no flow prob before? any pointers where I'm heading? new cartridge? something else?
thanks for any tips JimK
