## Customer Reviews

### ⭐⭐⭐⭐⭐ Finally found the right wrench key!
*by D***Y on February 4, 2015*

The Delta RP51345 works great on my Delta Leland 2575LF-RMBPU bathroom faucets (I have 3). I spent a small fortune trying to find the right size wrench key for my Delta bathroom faucets. The Delta representative cannot help you if you do not know the exact model faucet. Finally, I went on the web and looked at every faucet with a 4 inch centercet and found my exact bathroom model. Then I looked at the printed drawing of each part of the faucet to get the aerator part number (it's listed on the specifications information for the faucet). It's sad that there is no other easy way to go about finding a wrench key to fit the aerator, but after some effort, I finally found that my aerator part was RP51345. Next I searched for this aerator part, which conveniently comes with the wrench key. It fits perfectly. It is much smaller than some of the other wrench keys I tried. One of the keys and aerators that I bought fits my Delta kitchen sink, so at least some of my money was well spent. At some point, I was so outraged with my faucet and not being able to find the correct wrench key, that I almost replaced our Delta faucets to get "regular" aerators that did not require a wrench key to remove. I'm not sure why the builder did not leave the wrench key under the sink when the house was built (only 3 years ago)... I may not have known what it was at the time, but I would have kept it in a safe place. I hope this information helps the consumer to know how to find the correct wrench key when you suddenly get lime buildup in your faucet and can't figure out how to remove the aerator.

### ⭐⭐⭐⭐⭐ Be sure to know the size of the aerator when ordering
*by D***. on December 1, 2021*

Like several others I have a Delta Lahara faucet for my bathroom sinks. I went to Menards and Lowes who both only had the larger (red) aerator key tool. I initially thought that this was the correct size (for my Delta kitchen sink it is) but unfortunately is too large for the smaller aerator on the bathroom sinks. I was noticing very low flow in the sink despite having fresh valve stems and seals so I figured it must be the aerator and it turns out that's exactly what it was. The result of years of hard water through it. Once the original aerator was out using the blue key I was able to clean up the threads and put in the new aerator which completely fixed the problem. Make sure you get the correct size aerator for your faucet model. I just wish they sold several aerators with the one key as I need several more but only the one key.

### ⭐⭐⭐⭐⭐ Success
*by B***M on October 13, 2024*

These worked just fine for my Delta Lahara faucets.
