My Franke Ascona kitchen tap (only 2.5 yrs old) recently started dripping from the faucet.
Pretty sure it’s the hot side that’s dripping as water is tepid or room temp rather than ice cold. Dismantled and descaled both hot/cold cartridges (using vinegar solution) to be safe (we live in medium water area so do get some limescale) but has made zero difference.
Can the cartridges really need replacing after only 2.5 yrs?
The other thing confusing me is the drip isn’t consistent. Sometimes it’s slow & steady, sometimes it’s a continuous trickle of water rather than a drip, and sometimes (rarely now) it stops altogether but the latter usually only happens immediately after running the hot tap fully open and hot for a period of time. This change of flow happens spontaneously over the day without anyone touching the tap.
Any idea what’s going on?
