Rated 4 out of 5 by from It is a great faucet. This is a replacement for a 22 year old Delta single handle bathroom sink faucet. The original all metal. The new one is plastic with a chrome finish. I am interested in seeing how long the finish will last. The cartridge on the original started to fail and it leaked. I tried to get the unit apart to replace the cartridge, but being all metal construction the set screw in the handle would not loosen. I hope the finish on this unit lasts 22 years.

Q&A

What is the difference between Delta Classic 521-PPU-ECO-DST and 521-ECO-DST-A. I purchased one of each from two different stores today and must now decide which to use. One was $10 more than the other (Lowes vs. Home Depot). Help!!

Asked by: Louis
Hello Louis, Thank you for your question, I would be happy to help you. The 521-PPU-ECO-DST and the DST-A are not different at all, the A tells you what store it was purchased from. However both faucets are manufactured exactly the same. Please contact us back for any further questions or concerns. Best Regards, Nicole

Why is almost no water coming out of this faucet? It is about 6 months old. Hard to brush your teeth or even wash your hands. Both valves are fully open. The rest of house has excellent pressure.

I have slow draining in the sink with hot water (like an air lock) and normal draining with cold water. Is there something special about the pop up that would cause this? I have a plastic pop up with my model.

Asked by: KenW
Hi Ken, Thank you for your question about the Delta Faucet model 521-PPU-ECO-DST Classic Single Handle Centerset Bathroom Faucet In Chrome. I am sorry this information was not readily available, and I am happy to help! The temperature of the water shouldn't have an effect on the drain pop-up. I recommend removing the stopper to troubleshoot and see if the issue remains without the stopper. https://support.deltafaucet.com/s/article/Can-I-install-a-PPU-or-MPU-so-the-stopper-is-removable Please contact us directly if you have any questions or need additional assistance.
