We had a call quite a while ago for a condo in the Turnberry Towers to change out the cartridges in the master bath lavatory sink faucet on the left hand side due to some water spotting around the handle. It was a quick call and the cartridges were replaced very easily. The faucet manufacturer was Rubinet from Canada and they shipped the replacement cartridges to the homeowner for free. We got another call today to replace the right hand side cartridges due to some water hammering in the wall when the lavatory faucet was used. We instructed the homeowner that the cartridge may fix it but it could possibly require a hammer arrestor installed at the angle stop also. We said we would try the cartridge first and see if that does it. After a quick replacement without any issues and turning the water on, the water hammer was gone.
We just wanted to give a quick plug to Rubinet for the excellent support they have for their products and the fact that they will ship new cartridges to the home owner for free. I personally no of other companies that wont do this and have had a few incidences because of it.
