Is this your part?
Shut the water, pull the handle and escutcheon, unthread the bonnet nut and lift the cartridge out. RP19804 is molded into the body, the housing runs 4-1/16 in. long and 1-29/32 in. across, and the cap carries the rotational limit stop. The install date of the shower is the fastest tiebreaker.
When to replace it
The shower drips at the spout or head with the handle off, swings hot or cold when a toilet flushes, never gets fully hot, runs weak, or the handle turns hard and will not hold its setting.

How to install it
Time: 15 to 30 minutes. Tools: Phillips screwdriver, Adjustable pliers, Hex key.
- Shut the water at the main or the integrated stops.
- Remove the handle and escutcheon.
- Unthread the bonnet nut and draw the old cartridge straight out.
- Seat the new cartridge the way the old one sat. Delta puts the raised stop on the cap toward the hot water inlet, the left in a normal installation. Wrong orientation reverses hot and cold.
- Refit the bonnet nut, run the full hot-to-cold range, then refit the trim.
Questions
Is the bonnet nut included?
No. Reuse the brass bonnet nut in your valve. Delta sells it separately as RP22734.
My valve was installed after 2006. Is this right?
Probably not. MultiChoice valves built from 2006 take the RP46074, which FourHome also sells.
Hot and cold are reversed after the swap. Why?
The cartridge is in backwards. Delta puts the raised stop on the cap toward the hot water inlet, which is the left in a normal installation. Shut the water off, pull the cartridge, turn it half a turn, reseat it and check that cold water flows first.
How do I set the maximum hot?
Set the limit stop on the cap to match your old cartridge before the handle goes back on.
