Rated 4 out of 5 by from Looks great Looks great but not much water flow. Easy to install.

Rated 5 out of 5 by from Nice chrome replacement for old fixtures. Nice faucet and easy to install. My only concern is teh use of PEX plastic supply lines, but this seems to be a typical material with current Delta products.

Rated 5 out of 5 by from Pleased with design, function and color match We are very pleased with design and function of this faucet. It was a great color match for our old Kohler which was discontinued.

Rated 5 out of 5 by from Delta does it again! This faucet when bought from a a reputable place like Fergusons Home is a solid and beautiful. I love how it functions. I am very happy I decided on the Delta Cassidy.

Rated 5 out of 5 by from Well-constructed with beautiful finish Fine quality casting on brass base metal, with beautiful polished-nickel finish. (Hint: Keep a cloth handy to wipe up water splashes after each use and you won't have spots that you'll have to clean off later.) Installation was very easy with included wrench. Plastic (PEX?) supply lines and fittings were a new thing to me but went on well. Instructions could be clearer regarding the use of the additional supply line fittings--only needed if you want to trim the lines. I kept the lines original length and simply looped them around. Certainly, the finest quality faucet I've ever had.

I have a Delta Cassidy 597LF-SSMPU in my bathroom. The water flow coming out if the faucet has slowed. The amount of water coming out of the faucet is much less than it used to be. Does something need to be cleaned or replaced?

Asked by: Andrew Somple
Hello Andrew Somple, Thank you for your question! We apologize for the flow issue you are experiencing and will be happy to help you. Reduced flow is typically caused by the debris. We recommend flushing the unit. To flush the unit: Remove aerator using supplied wrench and turn faucet handle to the full on mixed position. Turn on hot and cold water supplies and flush water lines for one minute. This flushes away any debris that could cause damage to internal parts. Reinstall aerator with wrench. Check all connections at arrows for leaks. Retighten if necessary, but do not overtighten. Please refer to page 4 section 5 of the maintenance and installation guide for more details. I have attached the link below. https://media.deltafaucet.com/MandI/86520%20Rev%20F.pdf Thank you for being a loyal Delta Faucet customer. We look forward to continuing to serve you.
