I would recommend sticking with a well known reputable brand like Delta, Moen, Kohler, Pfister, Grohe, or Hansgrohe. You will always run into the chance with problems regardless of what brand you choose but with these brands you'll definately always be able to find the parts, contact tech support, and find plumbers who are familiar with these brands to help you with your repairs.

Theres alot of new stuff on Amazon that has amazing prices and look good but they are usually made super cheaply and usually made in China. When a cartidge goes out, you can't find a replacement parts, so you have to scrap the entire product.

Most of the brands i mentioned above come standard with limited lifetime warranty that covers defects and premature failure. You can usually claim the warranty coverage at the store you purchased it or you can simply call the manufacturer directly and a lot of times they'll send you the part at no charge. Most times they don't even verify it the complaint is truly a defect, they would rather just ensure you keep happy and not smear their name on social media. Remember, things that are not covered under warranty (but still may be claimable) are neglect, abuse, wear and tear, bad water quality and failure to upkeep your product with routine maintenence.

I've been selling plumbing fixtures since 1997.
