PRODUCT FEATURES
Single-function valve cartridge controls the temperature at full output flow. Monitors water pressure to balance temperature. All Delta® tub and shower faucets are engineered to keep the water temperature within a safe ±3.6° F (±1.7° C)*. This technology makes sure your family doesn’t experience a sudden and possibly unsafe change in water temperature as a result of running water elsewhere, such as using a dishwasher, flushing a toilet or running a washing machine. The valve cartridge features an adjustable handle limit stop that, when properly set, helps ensure the handle cannot be turned to a position that is too hot for comfort*. The handle limit stop's integrated design allows easy adjustment via pull and turn. Easily replaced seals make maintenance a snap.
Comes with all Delta pressure balance tub and shower faucets.
*Requires inlet water temperature be set correctly. May require seasonal adjustments.
- Monitor® single-function pressure balance cartridge
- Use with Monitor® 1300/1400 Series tub & showers produced before March 2006
- Allows for temperature control
- Integrated rotational limit stop

Miserable quality, expensive paperweight
They don't last. We have two showers on opposite sides of the same wall running the same water. In shower #1, the cartridge is as old as anyone can remember. In shower #2, we replaced the cartridge a year ago. $200 contract labor plus the cost of the cartridge. It lasted 6 months and started its ever-worsening leak when turned to the off position. $200 more plus the cost of another cartridge. The new one just suffered the same failure as the last two, and had to be replaced again. Another $200 labor, another new cartridge cost.
We're down almost $1,000 this year alone on these defective Delta cartridges. I might as well buy the knockoffs that cost a quarter of what these cost if I'm going to have to have them replaced every 6 months.

not enough hot water
new RP19804 cartridge installed but water just gets warm not hot enough and was not an issue prior to changing and changed due to minor drip. Other facets in the room are normal temp for hot water. What can be done?

Nothing Better Than OEM
Buying directly from Delta rubber stamps OEM components that are built to last. I've learned my lesson about the risk of selecting after market items or those that are advertised as compatible with OEM parts. If you're a DIY guy, especially when dealing with plumbing repairs, my advice is to buy OEM and enjoy significant savings on plumbers fees when the job is complete. More often than expected, 50-75% savings on a part can translate into the frustration of having to repeat the repair and do without for a longer duration until the OEM part is delivered. Being greedy has its unfortunate consequences, so trust Delta over third party sources!

Offer warranty but don't answer the phone
Don't buy. Good luck getting warranty. I called the 1800 number for warranty and the message said 'in a department meeting, goodbye'. then hung up. Wow, an all-day-long department meeting....
