RP1991 Shower Cartridge Compatible with Delta 1600 Series Scald Guard

Worked perfectly.

Bought a couple of these. I have 2 older bathroom and I don’t feel like dumping a bunch of money into them since I will be redoing them at some point. Plumbing supply company wanted over $100 for these. This fits just like factory and they haven’t leaked at all. It can be a little tough taking the old ones out if you have hard water. Just make sure you put the spring back in the same way they came out. Otherwise it takes under 5 minutes. Replaced the old ones because one leaked and the other one would allow hot water through.

Worked well enough in our Delta faucet from the early 1980s. When turning the knob the feel isn't as smooth or solid as the original, but the leak has stopped. I got lucky, the old faucet came apart easily. Maybe a 20 minute job.

Great replacement.

If you've ever had a leaky shower, either coming from the shower head or the shower handle, then it's helpful to know how to diagnose and fix it. Plenty of YouTube videos on how to do that. Make sure you have the right part number. Once you have that, it's easy to do, takes less than 15 mins. And then the leak is likely to be gone! This replacement part works perfectly, and importantly, includes the springs and rings to replace the old ones. A+

I’ve bought this twice now to repair a leaking tub faucet. It lasts as long as the original Delta cartridge, is available, and works just fine.

It was missing 1 rubber seat.

Perfect !

Great price. Fits perfectly.

Thank you

I used a little vaseline to hold the springs and rubber seals in place . Once the water is turned off at the tub , its a 10 minute job to replace the seals

Installed quickly. No leaks. Just like the original.

upgraded cartridge worked great !! Thank you .
