Installation Information


Rated 1 out of 5 by from Bathroom Worst tub and shower faucet on the market. If I'd had known I would have brought a cheaper version. Mixing valve will not mix hot water.(Period) I can only get cold water to come through this valve. I know its the valve, because when I remove the valve hot water comes through. Don't waste your money. I would have returned it to Home Depot if it weren't for the fact That everything is already installed!

I installed this cartlidge. It fits perfectly with no leaks but, it twists in the opposite direction of the original, and the tempreature of the hot water coming out is just warm. Please help

Asked by: Celil
Hi Celil, Thank you for your question! The cartridge has a Rotational Limit Stop which can be adjusted to allow you turn the handle further on the hot side. Newer units will have a gray stop that you can pull out, rotate, and set back into place. Each notch will change the maximum temperature 3-6 degrees. Please click the link below to view our How-To Video for adjusting the RLS. https://www.deltafaucet.com/video-gallery/video-page?videoId=n2_uZ7wgV1I Best regards, Tanya

our old cartridge looks different with a semi circle on top , the new one is more enclosed. will it work?

Asked by: David
Thank you for your question, David! The original RP19804 cartridge did have a semi-circle or raised stop that was visible. The cartridge now has an enclosed rotational limit stop but will still work in place of the older version. Best regards, Edward

I have replaced rp19804 cartridge, but, there is one problem, when I turn my faucet slightly to the left I'm getting hot water instead of cold one. What have I done wrong?

Asked by: Victor
Thank you for your inquiry, Victor! Normally, if you are getting hot water in the cold water position, this means the cartridge assembly is installed upside-down. You would want to remove the cartridge from the valve and rotate it 180 degrees and re-installing it. Best regards, Tanya

I just received replacement part RP19804 and I'm having trouble getting the bonnet nut to brake loose. Would soaking it over night with a rag soaked in white vinegar help? Or, is there another solution to my problem? Thanks, DW

Asked by: Darryl
Hi Darryl, Thank you for your inquiry! The bonnet ring should unscrew counter-clockwise for you. If it will not unscrew for you, then I would suggest using a 50/50 or stronger mixture of tap water and white vinegar. Soak a rag in the mixture and wrap the rag around the bonnet ring area. Use tongs if necessary. Leave the rag in place for 15 minutes or so. This should help dissolve the calcium build up, so that the bonnet ring will unscrew for you. Remove the rag and attempt to unscrew the bonnet ring or you can leave it on so that you do not scratch the bonnet ring with your tool. Make sure that the entire valve body does not start to rotate as you do this. Repeat if necessary up to 4 times, taking care to protect surfaces that may be damaged by vinegar. The white vinegar can stain porous stones like granite, limestone and marble. Best regards, Tanya

New rp19804 low hot water pressure

Installed a new RP19804 last month, the flow/pressue of hot water has dramatically decreased. Cold water is fine and hot water is normal for the rest of the house. What could be causing this?
Asked by: ML
Hi, ML! I am sorry to hear that you are experiencing low flow from your shower unit. You may have some debris trapped in the valve body or cartridge assembly that is blocking the water flow. You may need to clean out the cartridge assembly and flush out the valve body. First turn off the water supply to the faucet. Remove the handle assembly, unscrew the bonnet ring and remove the cartridge assembly and all seals. Rinse and clean the cartridge out thoroughly. Turn both the hot and cold water back on for 10 to 15 seconds to flush out the valve body. After the allotted time, turn the water off and reinstall all of the components. Make sure that there is no debris on the cartridge assembly and seals. If this does not resolve your issue, then the cartridge assembly may need to be replaced. Best Regards, Rosanna

Looking to change shower trim on 1996 single lever multi choice with temp adjustment at tip of handle.

Cartridge works fine. Do I need to change it before I can change to modern brushed trim? If so, which cartridge?
Asked by: Richroof
Hello, Richroof, Thank you for your question! You can install any 13/14 series trim kit on the existing valve using the original cartridge or a new RP19804. Best regards, Jon
