Rated 5 out of 5 by from The right parts for the job! After trying so called "equivalent" replacement parts from a "big box" home improvement center and from a local hardware store (and having them leak) it was great to get true manufacturer's parts. They fit . . . and they WORK!

Is there a 1 inch stem extension for this product?

I need to extend the stem approx. 1 inch and have been unable to find any extension around this range. Does one exist?

Hi Max22, Thank you for your question. Unfortunately, we do not have an extension for this stem unit. Thanks, Jon

How do I remove the handle on my rp1740?

Asked by: Bill
Thank you for your question. Without knowing which handle you have, it is difficult to advise you on how to remove it. Some of our handles are held on with a set screw on the side of the handle, and some have a screw in the top of the handle underneath the button.

RP1740 vs RP25513

Both look like same except brass and plastic. Our bathroom faucet have brass stem cartridge with two handle centerset type. Can RP1740 cartridge be used in place of the RP25513? Thanks in advance.
Asked by: W
Hi, W! Thank you for your question. The RP1740 are plastic and they are meant for faucets that have knob handles like the clear, acrylic, crystal-looking handles. The RP25513 are brass and they are meant for faucets that have metal-lever handles. Best Regards, Rosanna

The handle on tub has broken off. How do I remove the RP1740 stem?

I have the Neostyle white porcelain with chrome base handle which says HOT in black. It's two separate handles, with a spout which has the round pull down under it to turn on the shower, in the middle. None of the three are attached together. This was hit accidentally and broke off. White piece is in the handle, which I removed, and looks like the end of the RP1740 stem. What is the best way to remove the stem now that it's broken off at the tip? Can I use the RP25513 with the copper tip instead. If I do decide to replace the both handles, also with the neostyle, just in chrome or otherwise. What size would these be considered on the tub? It looks like the H27 is for a sink and could possibly be smaller then my tub handles but I'm not sure of this as the H27 also looks exactly like the tub handle. Same location for the set screw, same base shape & same grooves on the bottom of the base for attaching to next part. Also, I purchased the RP4993 seat and springs. Is this all I will need, the RP25513 and RP4993? Do I need any other o'rings or seals? Any extra advice welcome. Thank You
Asked by: Terri
Hi Terri, Thank you for your question. The part that you see exposed is probably the RP18627 stem extender. This piece fits on top of the RP1740 stem assembly. The chrome trim sleeve that covers this piece will unscrew and give you access to the stem and stem extender. Neo Style handles still available for your faucet include the H25, H27, and the H46. Substitute the RP24096 for the RP25513, and with the RP4993 will update the inner workings of the faucet. Thanks, Dave

How do I remove the seats&springs from my 2 handle faucet? Model # 2131.

Asked by: Trouble
Hi Trouble, Thank you for your question. To remove the seats and springs from your model 2131 faucet first shut off your water supply to the faucet. Pry off the hot/cold buttons on top of the handle to gain access to the screw holding on the handle. Remove the screw and the handle. Next unscrew the bonnet nut holding down the stem assembly, it will unscrew counter-clockwise. Once the bonnet nut is removed pull up on the stem assembly to remove it from the valve body. The seats and springs will be located in the valve body directly underneath the stem assembly. Use a small screwdriver to remove the seats and springs. Here is a link to the parts breakdown of the model 2131 to help with your repair. http://www.deltafaucet.com/customersupport/documentation/2131.html?document=pd Thanks, Dave
