The genuine three-handle Delta part that turns a leaky tub faucet back into a working shower switch

For the classic Delta three-handle tub and shower setup, the RP17730 is the assembly you want in hand before you shut off the water. It is a chrome-finished diverter built to original Delta specifications for non-pressure-balance models 602, 606, 612, 622, 632, 636, and 642, so if your faucet is one of those, the part number is your answer. It is small and light — the body measures 0.75 x 2.5 x 2.5 inches — but the plastic construction means the seal quality does the heavy lifting.

Performance is the strength here: smooth operation once seated and a clean switch between spout and shower. That is the main reason it sells, and the same experience shows up in the customer feedback — one owner notes the diverter is “a bit tight” and needed “quite a bit of force to get it to full seat,” but that “no leaks, and plastic quality\strength is above average.” That pattern repeats across owners: a stiff first week that loosens into normal operation, usually after a little lubrication and a light tap with a wood block over a helper’s hand.

There is a genuine caveat about this part, and it is worth naming honestly. The tight fit on a decades-old valve body is the most common complaint, and a few owners received stems that had to be filed down slightly before they would seat. The factory warranty is a lifetime limited warranty on the faucet and finish, but replacement parts can be slow to obtain if you ever need a second one — most buyers find it is faster to simply buy this assembly again. If your valve body is pitted or corroded inside, expect some filing and patience before the new stem slides home.

The small chrome stem that ends the spout-drips-while-you-shower problem on Moen two-handle faucets

If you own a Moen Chateau two-handle faucet and the sprayer keeps running at the same time as the spout, the 14960 is almost certainly the fix. It is a light little part — 1.13 ounces — that screws into the valve with the included bolt, and the hexagonal socket on the end is what lets you torque it in with the supplied tool. No deep sockets or specialty tools required. That is the practical beauty of this design.

Owners describe the swap as quick and satisfying. One sums it up well: “It took me 10-15mins and I was done installing it. It fit perfectly and worked perfectly! Now when we use the sprayer the water has completely stopped coming out of the faucet at the same time.” When the seat is clean, that is exactly the experience — screw in, tighten, done, with the spout and the sprayer finally working as separate outputs instead of both at once.

The honest catch here is the tooling and the quality ceiling. The included bolt that is meant to grip the plastic hex socket is on the small side, and pulling a seized 20-year-old diverter out with it can strip the socket instead of turning it. Owners also note the replacement does not feel quite as substantial as the original Moen part, so if your faucet is old and truly stuck, budget a separate hex key as backup. With a cleaned thread and a dab of lubricant, most installs seat on the first or second try.

A solid brass rod-and-plunger cartridge that brings a stuck shower diverter back to a ten-minute job

Some diverters are not stems or push buttons — they are internal cartridges that slide in and out of the valve body, and the Ebrmeiwo 89773 is built for that style. It measures 1 x 1 x 3.7 inches with a 0.5-inch inlet, and it is made of high-hardness brass for rust resistance and a long service life. The length is the number to check against your old part before ordering, since this is not a universal fit and a millimetre of difference is the difference between seating flush and leaking.

Owners who match this correctly describe near-instant results. One notes it worked on a Kohler Purist and that though the rod end is threaded where the original was smooth, the button trim fits on just the same — a good sign of how tolerant the design is once the body length is right. Another calls it a “ten minute fix,” removing the old cartridge and installing the new one with a socket wrench and a plumber’s shower socket. The brass body with O-rings seats tight and does not leak.

The catch worth flagging involves tooling. This cartridge needs a 7/8-inch deep socket to remove and install, and that size does not come in standard plumbing sets — a smaller metric socket will round the hex and cost you the job. Owners also note the old cartridge is theoretically rebuildable if you can source the right O-rings and plunger, but hard rubber parts for these cartridges are difficult to buy separately, which is exactly why a full replacement is the practical path. Bring the right socket and you are done in minutes.

A short metal push button that screws straight into a Moen shower valve and ends the stuck-diverter routine

Push-button diverters are the more mechanic-friendly side of tub repair, and the Ebrmeiwo 1198 is a compact example at 3.03 inches long with a metal body that resists rust and corrosion. It threads into the valve rather than seating inside a spout, which shortens the job to a few steps and keeps the replacement part out of sight behind the trim. If your old tub spout has stopped switching between shower and faucet, this is the style to look for.

Owners genuinely like the feel of this one. The included O-rings help — you get one spare in the box along with a dab of pipe dope, so it goes in smoother than a bare-metal stem. One owner described how the deep 1-inch socket with a 3/8-inch ratchet made the swap easy, with a little silicone grease on the O-ring, and how the valve operates smoothly where the old 25-year-old hard-water-damaged one had seized. Another notes the part brought a 50-year-old bathtub diverter back to life after an accidental bend.

Not every install ran perfectly. In at least one case the push button engaged and disengaged fine for a few weeks and then stopped holding, forcing a manual pull-out from then on — a reminder that the mechanism is a small plastic-and-metal assembly and cannot be treated like a permanent fixture. For most buyers though, this is a clean fit and a clean fix, particularly on Moen valve setups where push-button diverters are the standard design.

For when the whole tub spout has given up — the factory Moen rebuild kit that skips the full replacement job

This is the kit you want when the diverter in your Moen tub spout has worn out but the spout itself is still solid. It is a genuine Moen service kit with a chrome polish finish, single-hole installation format, and a metal handle to grip.

The kit solves a specific, common failure: a spout whose built-in diverter has caked up with minerals and no longer seals. Owners describe the outcome simply and clearly — one says it was the perfect solution for a diverter that was badly scaled and no longer working, and another describes how the inner plastic valve and washer fit perfectly with the original spout. If you already own a Moen tub spout and its diverter has failed, the correct fix is almost always the internals, not the chrome.

Read the contents before ordering, though. The included diverter pull is shorter than the original Moen part, and the post in some kits is longer than the one it replaces — a couple of buyers ended up reusing the original post instead. The plunger clip also sits a touch looser than some owners would like. None of those is a dealbreaker, but if your old spout is on its last legs mechanically, replacing the entire spout can be the cleaner path. And note the warranty is one year limited, which is shorter than Moen’s lifetime coverage on the faucet itself.

A full rebuild-in-a-box for Price Pfister Verve faucets — handles, stems, seats, and flanges in one package

For a Price Pfister Verve three-handle faucet, this is not a single diverter — it is the whole trim replacement. The Ratiekc 39619 kit includes the hot and cold handles as a pair, the diverter handle, two 12H-2H/2C stems, a 12H-18D stem, three #38 seats, and three flanges and nipples, all in a chrome finish with brass stems and plastic handles. It even throws in the 31/32-inch socket wrench you need for the stems, so you can start the job the moment the box arrives. Uses a screw attachment mechanism for the handles.

When it fits, buyers are very happy with the value. The kit arrives looking like a complete rebuild, and the price relative to replacing the faucet is a big part of the appeal. Customers note it worked well where the parts matched — one notes that they initially thought the seats were missing, then found they screwed in cleanly out of sight and worked great. For a faucet body that takes 39619 parts, this replaces every wear item in one order.

Two things to know before ordering. First, the kit is only for Price Pfister Verve faucets — it looks similar to 39695, 39672, 39621, and 39620 kits but is different in size and brand, so check the model carefully. Second, the trim is plastic, not chrome-plated metal — the handles and stem covers do the job but feel lighter than a metal trim set. On a setup that uses 39619 parts, though, this is still the simplest way to get everything you need in one box, wrench included.

A full Delta 600 Series trim rebuild that refreshes the whole shower face, not just the diverter valve inside it

If you have a Delta 600 Series shower valve with a leaky diverter and a knob that has seen better days, the Avenuebool RP6046-compatible kit fixes both in one shot. The trim comes with a push-button diverter alongside a replacement handle, rubber seats, springs, O-rings, a plastic cam, rubber packing, a stainless steel ball assembly, a wrench, an escutcheon, a bonnet with adjusting ring, a sleeve, and two screws — everything needed to pull the old trim off and start fresh. The knob is acrylic with a chrome finish and the ball assembly is stainless steel.

The standout value here is the completeness. Buyers regularly note that every tiny part pictured is in the box — no mid-job runs to the hardware store for a missing washer or spring. The acrylic knob and stainless ball assembly do the day-to-day work, and on a Delta 600 Series body the trim snaps together as designed. When the install goes cleanly, this is a straightforward way to bring an old shower back to new without touching the valve body.

If you have never disassembled a Delta ball-type valve, plan the job carefully — this is not a screwdriver-only swap. The kit does not ship with instructions, and the parts need to go in a very specific order. Owners who did their homework describe the process firmly: watch a few YouTube videos matched to your exact Delta style, install the metal sleeve around the valve body before assembling anything else, and expect the job to need a helper and some patience. Getting the sleeve order wrong or using the wrong rubber inserts leads to a complete redo, so clear an afternoon before you start.

The full brass rebuild for aging American Standard Heritage valves — stems, handles, and diverter all in one kit

Older American Standard Heritage tub and shower valves have one habit that makes owners pull their hair out: the individual diverter stem is not sold on its own, so replacing a single dripping diverter means buying or borrowing a whole rebuild kit. This is that kit. The KISSLER RBK4110 includes brass stems, escutcheons, handles, and a diverter, so the entire valve can be refreshed with one purchase. All brass construction, threaded 0.5-inch inlets, chrome exterior finish, and a one-year manufacturer warranty.

For an older valve body, this is the practical path. Buyers installing it to replace decades-old tub sets describe the fit as direct and leak-free from the start, with quality brass that holds up. One notes the kit even included spares when purchased as a Like New resale — three escutcheons plus valves, handles, and diverter, with two full sets matching the original valve positions. When the internal parts match your valve, this kit does the whole job in one pass instead of hunting for individual stems one at a time.

The trade-offs are worth knowing up front. The handles in the kit are noticeably smaller and lighter-feeling than the originals they replace — some owners describe them as cheap imitations of the original hardware — though the internal stems and diverter are what actually stop the drip. The stems themselves are also shorter than the originals in some cases, which can be a problem if your old valve body has pitted seats that the shorter stem cannot fully seal against; where the length matches, the fix holds, and where it does not, the drip continues. Because of that, this kit rewards measuring the old stems against the new ones before you commit to installing anything.
