Rated 3.5 out of 5 by 2 reviewers.
Rated 2 out of 5 by Mold Mildew and Dirt Accumulates in Two Seams of Faucet Body I deeply regret purchasing the Model 520-DST due to the mildew, mold and debris that accumulates in the seams of the body of the faucet on both sides of the handle. It is a constant battle to keep these areas clean to modern standards. They are very difficult to clean properly. A solid body like the Model 525 faucets I had before are a much better designed product for ease of proper cleaning. Delta can do better than this! May 4, 2012
Rated 5 out of 5 by Great replacement I purchased a Delta Faucet about 8 years ago and it worked really well until the other day. It had a small internal leak. I called Delta and exclaimed the problem and they sent me a new one without any hassle whatsoever. The new one is even more attractive and works with greater ease. It is also easier to clean. I cannot say enough about how well Delta stands behind their lifetime warranty. November 13, 2015
