January 14, 2018 -

Howdy!

Trying to help a friend who has a leaky shower, and I am assuming that the cartridge needs to be replaced. For reasons that are too stupid to go into here, it would be best to purchase the cartridge before turning off the water and removing the old one.

My GoogleFu has failed me and I have not been able to find this exact trim set online. I will post two pictures of the faucet (ignore the calcium deposits, not my fault). Other information that may or may not be helpful is that the house was built in 1988. The original builders were either amateurs or "professionals" that should not ever be referred to as professionals (seriously, some of the dumbest things I have ever seen were done in the construction of this house).

DELTA appears on the bottom of the trim. Scald Guard appears at the top. As you can see, there is a single Phillips head screw in the center of the handle. There are two Phillip screws in the 5 and 7 o'clock positions around the handle.

Thanks. If there is any other information I can provide, I will be happy to oblige.

p.s. This bathroom is going to be eventually gutted and completely renovated, but that can't happen until some other more pressing matters are addressed. So stopping the leak is a stopgap measure.

May 19, 2025 -

I have a Delta shower valve from 2007 labeled "MONITOR 1400 Series" on the trim kit. I’m trying to identify the cartridge model. According to Delta, it could be either RP19804 (older, white top) or RP46074 (newer, gray top), but the only way to know for sure is by checking it. I removed the trim and saw the top is white. Does that confirm it’s the RP19804?

How to identify delta cartridge
Delta typically uses chrome and brushed metal finishes. The handle is another distinguishing feature - it's either plastic or metal. Another way to identify your faucet is by checking if it has a scald guard. You can remove the faucet handle using an Allen wrench, which usually secures the screw on the side of the · handle or under the decorative cap on top. If you find a scald guard where the cartridge is located, this narrows down the search.

June 5, 2017 - I have a shower with an old Delta Monitor faucet. I think it's a 13-series (from early 1990's). I've nursed it as long as I can, now I need to replace the cartridge. It appears the cartridge is no longer available from Delta, that there may be a replacement or conversion kit available instead.
