Until we have our old steel pipes replaced, we’re dealing with rust that apparently gets caught in our faucet cartridges, thereby causing drips. We’ve had to replace them regularly. It seems like such a waste to throw out the entire cartridge when just the ceramic pieces and a washer cause the problem.
So rebuild kits aren’t available anywhere? I’ve searched with all the keywords I can think of.
The cartridge is the rebuild kit for the faucet.
They used to have a seal and a replaceable seat. Then the seats stopped being replaceable, and it transitioned to cartridges.
