Fix that dripping faucet quickly and easily - no plumber required.
by Fred (5 out of 5 stars)
April 18, 2017

This shower valve was so incredibly easy to install that I can't believe that I put up with that dripping shower faucet for so long. I was thinking it was an expensive tile busting job with new pipes, but that was not the case for this dripping faucet.

There are easy to understand videos on youtube on how to replace the old unit (turn water off, take off handle, take off sleeve, pull out old unit, put in new unit, put on sleeve, put on handle, turn water on - that's it.).

IMPORTANT NOTES:
1. There are two types of these faucets depending on the year of manufacture. Before 2006, these faucets were blue and had different dimensions. This gray colored unit of for faucets made 2006 and later.. If you aren't sure of the year, temporarily remove your old one and look at the color and measure it. I made this mistake and had to return it and get this one.
2. If the drip is minimal, it may just need new springs and seats which only cost a couple dollars. They are also easy to replace and will add life to the faucet at minimal cost.

OEM replacement, fits perfectly. See low pressure diagnosis & repair within this review...

Fits well as OEM replacement. There's a LONG story below... NO TIME for the LONG STORY?

Cutting it to a SHORT STORY: drilling out the housing ports & mixer cylinder with a 5/32 drill bit and as long as you do not have plugged/clogged piping causing the low flow issue this WILL INCREASE THE FLOW. I also used an air compressor with a small rubber tip and a can of WD40. It took some time and a lot of repetition, but finally got all the rust and particles out of the lines by allowing WD40 to soak and then blowing air into & through the lines.

I am not a licensed plumber. I am a hands on properly manager who does almost all his own work and I have a lot of experience with these issues. I've successfully completed tons of repairs myself. That being said...

My home had clogged copper pipes, which required a high powered air compressor with a small rubber tipped blow gun, a can of WD40 and a lot of patients.

The LONG STORY: Our bathroom was retrofit at the galvanized pipes and adapters added to add copper pipe where the new shower/tub valves were installed (2 valves, 1 shower & 1 tub/shower combo. The shower/tub combo is the one I had multiple issues with low flow/low pressure. They both were working just fine for years before the old galvanized pipes started to clog the copper tubing.

Shortly after the bathroom renovation, say about 3 years later we moved out of the home and decided to use it as a rental property. Our tenant made an "improvement" (translation: added a pressure regulator without owners consent & caused a major water pressure problem) the pressure regulator which our tenant added restricted pressure as intended, therefore created a low flow/low pressure issue, which allowed the newly added copper pipes to begin to collect bits and pieces of rusted pipe at the fittings and smaller bends and areas where they narrow into the Delta valve housing etc.

Rust/corrosion is something that normally happens with all galvanized pipes, so I'm used to clean out aerated faucet ends regularly. However my experiences with pressure regulators has been not been favorable. Pressure regulators are great for new construction with copper piping throughout the home where joints can break free and other seals may become weak from high pressure in the lines.

Older 1950's and earlier homes used galvanized steel pipes which in my opinion DO NOT NEED PRESSURE REGULATORS, never had them, and never had this problem which I now have with the "tenant improvement".

A plumber will tell you otherwise I'm sure. However my experience is that the pressure regulator on a galvanized pipe system allows poor flow and thus rust accumulates along with bits of rusted/broken pipes and begin to clog the system due to the lack of flow.

I've found galvanized pipes last longer where they are free flowing and do not have an restrictive devices, therefore all rust particles/pieces of things that flow through the pipes are allowed to flow through the pipes and out the faucet.

Aerators at the end of each faucet will always plug/clog up, this is normally a small problem and easily fixed by removing faucet aerators/filters from the end of the faucets and cleaning out the broken down rusted pieces from clogging it. However my problem wasn't so simple. Yes each faucet in the home had pieces of rusted pipe clogging each faucet, yet removing the rusted particles from all the aerators wasn't the complete remedy.

I first tried altering the Delta cartridges by drilling out the back flow rubber stops at each inlet port all while ensuring not to damage any of the plastic housing. Then separating the valve and removing the stainless steel mixing valve cylinder. I used a 5/32 bit and redrilled each hole to that size while holding a rag around it and placing it in a bench vice (actually hand held it with a rag and pliers and slipped a couple times which caused a couple gashes on my hand, I just thought I'd make it sound a bit safer, as I wouldn't recommend this way).

Okay finishing up... flow improved but it wasn't nearly where it should be, so back to diagnosing the issue. I still had low flow after removing the valve and free flowing the water through the housing (I'll go into this with a bit more detail later on) so I shut off the water for the 20th time and removed the valve once again. I blew out some of the water in both hot and cold side of the housing inside the wall with my 6 gallon air compressor.

Here comes the free flowing water shooting out the valve housing thing; I then took a can of WD40 filed up both sides of the copper lines and let the WD40 sit in there for a while, then took a towel and zip ties it around the outer edge of the valve housing to direct the water downward into the tub.

This gets MESSY! Use a long towel and do your best to secure it or have someone hold it over the housing by hand and direct the water downward with the towel into the tub, water will shoot out with a lot of force so it will most likely make a huge mess if you're not careful. I repeated this 6-7 more time and installed the valve, I still had a low pressure problem. I finally decided to attempt to blow out all the water in the lines both sides with my air compressor...

So I opened up the faucet in the bathroom sink to allow the water and air to vent as I forced air into the hot side & then the cold side. As I blew out all the water through the home in the hot side pressure would build and start to shoot back out from the force, I decided to close off the sink faucet and kept pressurizing the hot side it made bubbling and gurgling and out came so much rust and particles that I knew I had started to begin to get somewhere. I repeated this step over and over probably 5 more times and each time more stuff came out into the tub, until it finally seemed to run somewhat clear. I then did the same to the cold water side and finally after I felt I had gotten most of the rust and particles out I then installed the Delta replacement valve and turned the water back on. There was so much pressure I couldn't believe it. FIXED!

I wish Delta wouldn't have designed their valves with any flow restrictions built in, however there are mandatory regulations in place for manufacturers of water faucets etc.. Our government requires low flow/water saving designs by manufacturers.

There are ways to get around these manufacturer low flow designed products, I always modify my shower heads and anything else that restricts flow and creates a low pressure issue for me. It doesn't save water after the modification, however it saves time spent on the next low flow repair and I'd dare to go as far as saying saves you money on repairs. Good luck, any issues feel free to post a question/comment and I'll see if I'm able to help you out with some advice.

NOTE: If you appreciated this review please give it a "thumbs up/like" your helping me to continue to give honest/unbiased insight into products I've used and you may have questions about. Interested in a product but don't know enough about it and would like it reviewed? Please let me know and I'll see what I can do... Thank you

Great Delta "Gray" Replacement RP46074
by Chris L. (5 out of 5 stars)
September 1, 2018

I purchased this - as a direct replacement for a Gray RP46074 cartridge (this one is "White"). The color codes refer to the color of the top, where the anti-scald adjustment resides. I was having a very slow leak from the shower head of a Delta 13/14 Multichoice shower fixture. Some reviews/questions stated to replace the springs/washers - that must be for a different model as mine did not have that as an option.

Installation was quick and painless (any questions, check YouTube videos for "replacing RP46074 cartridge" and you will get plenty of vids that will walk you through installation.

Steps were:

Cut water off at meter

Open faucet to drain water

Remove handle

Remove escutcheon tube

Unscrew retaining screw (by hand - very easy - if hard to remove, use a flat, rubber jar opener)

Remove old cartridge, paying close attention to which side is the "HOT" side

Check the cartridge area in fixture for any contaminates and clean if necessary

Insert new cartridge - make sure it is seated all the way in

Screw on retaining screw (by hand - until you cannot any more - do not use tools)

Install escutcheon tube

Turn on water and test for leaks (do not put handle back on as this will hide the cartridge and you will not be able to see any small leaks)

Install handle and check scald guard

Easy Peasy! The scald guard on mine was set to minimum from the factory, I had to adjust it - simply pull the white part and turn to appropriate setting.

Again, very easy to install, a direct replacement for the "GRAY" RP46074, stopped all leaks. I mention the "Gray" part a bit so that one can be sure that this fits.

Delta Shower Cartridge
by Amazon Customer (5 out of 5 stars)
February 23, 2017

This is a replacement cartridge part for our Delta shower. The old cartridge is supposed to slide out and this new one go in without any difficulty according to the Delta video - and this should take about 5 minutes. Well, nothing goes according to plan and this was no exception. We could not remove the old part. It ended up breaking at the midpoint and we had to literally chisel the plastic and metal out! Two hours later, we got it removed, but ended up with a pipe leak! So, if you are going to try this, make sure you do NOT separate the two pieces at all costs. Keep wiggling it, even if it takes forever. I don't know if we had a weird bracket it went into, but it was a tight fit. There is nothing wrong with the part - it was perfect for our shower, just getting the old one out. Good luck! :)

This valve does not fit all 1400 series Delta bath faucets
by Quinton Q (2 out of 5 stars)
October 4, 2014

I purchased the RP46074 cartridge because the description led me to believe that it would fit my model 1430 Delta bath faucet. . I was very disappointed to find out that this cartridge did not work on my faucet. I had to go to Home Depot for the correct part. I probably should have tried Home Depot first. I have determined that the Delta RP19804 Cartridge Assembly was the item I should have purchased. This is the cartridge with the blue valve. Like at least one other purchaser, I made an error based upon what was printed incorrectly in the Amazon ad. Potential buyers should be aware that this cartridge does not fit all 1400 series Delta bath faucets!

Read the contents on the cartridge!
by Wolverine (5 out of 5 stars)

This came literally the next day after I had purchased it. It has been a month now and it works great. Please please please read the cartridge: there's a big "H" on it letting you know that where the "H" is at is for the hot valve. You think I'm being facetious? No, seriously I had the installer put the hot in the cold valve. So when I started my shower the hot was first and the cold was last. On the damn valve it says "WARNING: make sure that the cold water flows first."

Common sense isn't common anymore. Read things before installing. Two men tried fixing this valve and installed it the wrong way. It took me, a female, to read the info and haven't had a problem since.

Wrong part sent from Amazon
by Hao L. (1 out of 5 stars)
March 10, 2019

In the attached picture, the left is the genuine Delta RP46074 valve that is removed from my shower. Note that it has "RP46074" marked on the body of the valve. The valve on the right is what Amazon.com sent me. It is obviously a different part, and too bad I realized that only a few months after I bought the part when I found time to install it. And that's past the return window. $33.40 down the drain .... But for everyone else, don't buy this from Amazon.

I have no plumbing skill and I found it easy to install
by Mike (5 out of 5 stars)
July 25, 2019

I had a slow leak from my bathtub faucet. A plumber would probably charge $150-$200 to come to fix it. I was tempted to call a plumber because I am not handy at all, but after watching a few videos online, I figured I'd give it a shot. Turned out to be as easy as shutting the water off, removing one screw, unscrewing one piece, and swapping out the cartridge. Just like that, no more leak. I can't comment on the quality of this compared to other brands, but I can say if you're debating if you should buy this and try fixing the leaky faucet yourself, go ahead and give it a shot.

Exact fit, easy to replace
by Engineer Reviewer (5 out of 5 stars)

I was able to do this replacement with only a few tools. Took about 45 minutes, but with a little experience it probably could be done in half that time. After installation, no leaks and a perfect operation.

Fixed my dripped shower!
by Phillbert (5 out of 5 stars)

It looked different than the one I replaced which worried me, but it fit perfectly. This one is even easier to adjust the temperature on, which was nice. I've had no issues weeks after install, and it has a lifetime warranty. Nice!
