Rated 1 out of 5 by from Wasnt the right part. I was looking for the inside replacement parts, Aerator for the Delta victorian series. I looked up the part on the diagram on the site and that was the one it told me to order. It wasnt the right one.

can this areator RP53998 be used on a Leland model 978

Asked by: Handy dad
Hi Handy dad, Thank you for your question. The RP53998 has a thread size of M24x1. The model 978-DST has a thread size of M21.5x1 and will use the RP50815 aerator. The original 978 (non-DST) does not have a removable aerator. Best regards, Jon

Is this the correct aerator for 156-RB-DST bronze?

My faucet is bronze 156-RB-DST. This aerator says chrome. Is it the correct aerator for my faucet?
Asked by: Handymaam
Hi Handymaam, Thank you for your question! Items with no finish code may default to Chrome on the website. However, this is a cache aerator, so there is no finish on the part. This is the correct aerator for your model. Thanks, Jon

Can the RP53998 aerator be installed in the Delta Zella faucet to replace the rp52216 aerator

I would like to increase the water flow from 1.5 to 2.2 gpm. The current faucet uses a rp52216 aerator. I would like to know if the RP53998 aerator can be installed in the Delta Zella faucet model 35706LF
Asked by: Mark
Hi Mark, Thank you for your question! We do not carry a higher gpm aerator for the 35706LF model. However, you can search locally or online for a higher gpm aerator with the same thread size. Your aerator size is M21.5x1 male. Best regards, Brandis

The aerator that came with the faucet does not introduce enough air so the water splashes all around. Have you fixed the aerator since we bought it?

I am a plumber so don't bother asking me about pressure and flow because it is correct. The faucet is a D 4380T-AR-DST bought 10-4-2012. I will gladly buy this new aerator if you fixed it (or changed it) to introduce more air.
Asked by: Bruce
Hi Bruce, Thank you for your question. There has not been a change made to the RP53998 aerator for the model 4380T-AR-DST faucet. You may want to try a lower flow rate aerator like the 1.75gpm RP70718, or the 1.5 gpm RP60983 to reduce splashing. Thanks, Dave

Is thisthe correct aerator for 155-DST?

Asked by: Reggie
Hi Reggie, Thank you for your question. This is the correct part number for the 155-DST. However, based on the photo you have the pre-DST version of the model 155. The aerator for your unit is the RP37018 (or RP37018SS for brushed Stainless Steel). http://www.deltafaucet.com/repairparts/details/rp37018.html Best regards, Jon

Faucet 4380 dst

The aerator in the faucet model 4380 dst splashes water all over when rinsing dishes or washing hands. There are two aerators listed on the parts diagram. RP52216 and RP53998. How do I know which one I have in my faucet, which one would be less forceful and is there one that would be more gentle, like a shower spray?
Asked by: Mike
Thank you for your question. Delta Faucet model # 4380-DST contains a 1.8 gpm at 60 psi aerator. That is the RP70718. If you would like a lower flow aerator, we have a 1.5 gpm available with RP60983, a 1.0 gpm with model RP63886 and a .5 gpm with model RP60729.

Does the aerator wrench come with the RP53998 aerator?

Asked by: Rob
Hi, Rob! Thank you for your question. the RP53998 aerator does not come with an aerator wrench. You will need the RP52217 aerator wrench for this aerator. Here is the link for the part: https://www.deltafaucet.com/parts-product-detail?modelNumber=RP52217 Best Regards, Rosanna
