TOVEN-RV RP46074 Delta Shower Valve Cartridge Compatible with Delta 13/14 Series Bath Tub Shower Faucet Single Handle Universal Shower Valve Cartridge Repair Assembly Replacement Monitor Cartridge Parts

What I installed

I replaced a tired, dripping Delta single-handle tub/shower mixer with the RP46074 cartridge, a pressure-balance replacement for Delta’s 13/14 Series MultiChoice rough-ins. My valve body was a Delta MultiChoice (R10000 family), so the compatibility lined up. If you’re working on an older, pre-MultiChoice 1300/1400 body, this is not the right cartridge. That distinction matters: the old 1300/1400 valves use a different cartridge with separate seats and springs, while the 13/14 MultiChoice valves accept this all-in-one assembly.

Build and compatibility

The cartridge combines a brass stem with a molded plastic body and integrated seals. The machining on the brass was clean, the plastic shell was straight and free of flashing, and the O-rings looked evenly seated. It’s not fancy—no metal housing or upscale packaging—but that’s normal for this category. The included retaining clip fit the valve body snugly; I tested both the new clip and my original clip and stuck with the new one after confirming a positive lock.

Compatibility-wise, the cartridge is intended for Delta 13/14 Series MultiChoice bodies—typically labeled R10000 (also seen in R1800/R2200 variants). If you remove your trim and see “MultiChoice Universal” cast into the brass, you’re in the right neighborhood. If your valve is decades old and stamped 1300/1400 without the “MultiChoice” language, stop and source the older style cartridge instead. The RP46074 also won’t work for two- or three-function diverter valves; this is for single-handle tub/shower control.

Installation experience

Swapping a Delta cartridge can be straightforward—or stubborn—depending on how long the old one has lived in your wall. Mine had been in place for years, so extraction was the only fussy step.

Here’s what worked for me:

• Shut off the water supply, open the valve to bleed pressure, and cover the tub drain.
• Remove handle and trim. Pull the chrome sleeve and escutcheon to expose the valve body.
• Pop out the stainless retaining clip with needle-nose pliers. Wiggle the old cartridge straight out. Mine resisted; a gentle twist and steady pull (with a strap wrench on the body, not the stem) broke it free. If yours is seized, a dedicated cartridge puller is worth its weight in gold.
• Flush the open valve body for a few seconds by briefly turning water back on. This clears debris that can chew up new seals. Then shut off again.
• Clean the bore and apply a light coat of silicone plumber’s grease to the O-rings on the new cartridge.
• Orientation matters: the “H” side should face left (hot). Align the key on the cartridge with the V-shaped slot in the valve body and push it fully home. If it’s not seated all the way, the clip won’t lock and you can get leaks or poor handle engagement.
• Reinstall the clip, test for leaks with the trim off, then reassemble.

The included instructions are minimalist and the orientation marks are small, so it’s easy to overthink. A firm, straight push and a full clip seat are the two big success factors. Total time, including extraction drama and cleanup, was about 40 minutes.

Performance and temperature control

Once installed, the RP46074 did exactly what a pressure-balance cartridge is supposed to do. The handle movement felt smooth with predictable resistance. Temperature changes tracked consistently across the stroke—not luxury-thermostatic precise, but certainly within the advertised ±3.6°F range in my tests. I intentionally flushed a toilet and started a sink to provoke a pressure swing; the shower held its temperature without a cold shot or scald.

Flow felt normal for a modern shower setup. If your flow seems weak after install, check these common culprits:

• The hot limit stop might be set too conservatively, restricting rotation and reducing perceived “power” because you’re blending too much cold.
• Air in the lines can cause sputter; run hot and cold for a minute.
• Your showerhead may be the bottleneck; a clogged screen or restrictive head can masquerade as a cartridge problem.

Once I set the limit stop properly and bled the lines, I noticed no appreciable pressure loss compared to the worn unit it replaced.

Adjusting the anti-scald limit

Out of the box, the hot limit stop is set on the safe side. That’s intentional, but it can make the water feel lukewarm. Pull off the handle, expose the stop, and rotate it a notch or two to allow more handle travel. Make small adjustments and test. The goal is to top out just under your desired maximum hot temperature; this keeps showers comfortable without risking an accidental scald, especially in homes with hotter water heater settings.

Noise, leaks, and reliability so far

On first turn-on, I heard the typical brief hiss as the air purged; after that, operation was quiet. No chattering or whine at mid-positions. I’ve kept an eye on the spout and behind the trim for weeping—so far, dry. If you do experience a persistent drip after replacement, consider these checks before blaming the cartridge:

• Verify the retaining clip is fully seated and the cartridge is fully inserted.
• Make sure the valve body is free of mineral grit; debris can nick new seals on day one.
• Confirm you have the correct cartridge for your valve generation.
• For older, non-MultiChoice valves, worn seats and springs are often the root cause—this cartridge does not apply to those.

I can’t comment on multi-year longevity yet, but the initial seal integrity and materials give me no red flags. The one-year warranty is modest but typical for aftermarket cartridges.

What I liked

• Predictable temperature control with effective pressure balancing
• Clean, smooth handle feel
• Straightforward install if you’re comfortable with basic plumbing
• Good fitment in a Delta MultiChoice valve body
• Priced attractively versus OEM, while functionally equivalent in this use

What could be better

• Instructions are sparse; clearer diagrams and bigger orientation markings would help first-timers
• Packaging is bare-bones; a crushed box doesn’t inspire confidence even if the part is fine
• Extraction of the old cartridge can be rough without a puller (not the cartridge’s fault, but worth noting)
• Compatibility confusion persists between “13/14 Series” and legacy “1300/1400 Series”—a bold, front-and-center note would reduce returns

Who it’s for

• DIYers and pros replacing a leaking or temperature-swinging Delta 13/14 MultiChoice cartridge
• Homeowners who want an inexpensive, functional fix without replacing the entire valve or trim
• Anyone upgrading a guest bath or rental where robust temperature stability matters

Who should look elsewhere:

• Owners of pre-MultiChoice 1300/1400 Delta valves—get the correct legacy cartridge instead
• Those expecting thermostatic precision; this is a pressure-balance unit, not a thermostatic mixer

Practical tips for success

• Take a photo of the valve before disassembly and note the hot side left orientation.
• Flush the valve body before inserting the new cartridge; it prevents early seal damage.
• Use silicone plumber’s grease on O-rings; avoid petroleum-based products.
• If the old cartridge is stubborn, pause and get a puller. Excess force on the stem can snap it and turn a simple job into a headache.
• Set the hot limit stop with intention. It’s both a comfort and safety feature.

Final recommendation

I recommend the RP46074 cartridge for anyone with a Delta 13/14 Series MultiChoice valve who needs a reliable, budget-friendly replacement. It restored proper temperature control, eliminated the drip at my tub spout, and maintained solid flow with stable performance under everyday pressure changes. Installation is approachable if you’re methodical, though the instructions won’t hold your hand and removing an old, mineral-bound cartridge can test your patience. Provided you confirm compatibility and take the time to flush and orient correctly, this cartridge delivers the fix most people are after without the cost of an OEM part.
