What/where is 'the cartridge' and 'aeroator' on a kitchen sink?
Trying to see if I have a blockage in my kitchen sink (no hot water). I've read several responses about flushing my water heater and seeing a lot of talk of cartridges and aerators... and checking those as well.
Is the aerator the meshy part of the faucet, where the water comes out? Kind of like a filter?
And I have NO idea what/where the cartridge is.
Anyone mind explaining it to me?
TIA!
P.S. I have a single handle kitchen faucet... faucet doubles as a pull-out prayer. Kohler, I think?
