What do the different Warranties really mean?
Read all warranties carefully. Many cover only original owners and will not pass through if you are buying a new home. Some will say “Lifetime warranty” but it will only apply to certain parts of the faucet. You must register all of your products with the manufacturer. If you have problems, deal directly with them to establish rapport and/or a file. Do not go back to where you bought it, this used to be the case, but manufacturers have changed this practice. Keep all receipts of purchase and installation manuals/replacement parts breakdowns.
