Slow filling cistern
Any plumbers out there....
I've been at the in-laws recently, and they have 3 toilets in their house - and all of them take an age to fill up after they have been flushed. Looking inside the cistern, the water just trickles out from the pipe.
They doesn't seem to be a water pressure issue in the house, most of the time - it's just the cisterns that seem to have serious issues.
They're approaching about 20 years old...
Any suggestions ?
