Price Pfister kitchen faucet, couple issues

[greenjp]

Two issues going on with my kitchen faucet, not sure if they're related or not. First, the handle has gotten quite stiff to move. I have no idea what brand this is and a search for the number on the valve returned nothing. It's at least 13 years old and no more than 23 or so. Here are some photos - anyone know what it is? The tan plastic thing (sorry for blurry photo, I can take a better one if needed) screws down around the top of the valve, then the trim piece in the same photo screws down onto it. The handle is attached to the valve by a screw accessed by unscrewing a little cap on the top.

Second problems seems to involve the diverter valve for the hose. What happens is when the faucet is running there will be a clunk sound and the flow will decrease significantly. A quick tap of the trigger on the hose and it goes back to normal. If it's the diverter, is that a generic type part or would I need it to match the mystery faucet?

Instead of showing your lavatory sink show a picture of the faucet that you removed the parts from, maybe I can identify for you.
The cartridge looks similar to a Kohler but not positve yet.

It is a Price Pfister faucet. The cartridge is 974-074. Without seeing the faucet I'm guessing this is it.

Yes Marlinman, that's it! Ok so I should replace the cartridge, and I might get a new retainer nut (962-075) as the one in there got a little banged up during the removal and reinstallation. It's a weird soft plastic material. Am I correct that I should replace the diverter valve (951-039) to fix the issue with the flow?

 

[Marlinman]

I would defiantly replace the diverter.

I would defiantly replace the diverter.

Wow! I was expecting definitely but not defiant.

 

[Marlinman]

OOPs Definitely would change the diverter. LOL

Hello everybody. Turns out I needed the 974-035 valve, a new style brass retainer nut, and the 951-029 diverter (https://www.amazon.com/gp/product/B002YR7KTQ/). It is not obvious to me how I'm supposed to install the latter and I can't find any good how-tos. Any tips? Thanks,

Jeff

The gray on the bottom of the diverter is normally a push fit.
The top part looks like it threads on.

This is from a newer Phister faucet that uses a clip to hold the diverter on.

Ok the new valve and retainer nut are in and the handle movement is much nicer.

Still waiting for the diverter to arrive. Here's a photo of the current one, the copper coming out the end is going to the faucet, the braided hose on the left is the supply coming from the valve. I am not sure what I'm looking at here in terms of these connections and how to break (and then remake) them. All three have a little grey insert looking thing. Is there a technique or special tool for releasing these?

 

[Terry]

It's a push fitting. Take something like pliers or a wrench and force the gray part inward to release the grip on the pipe.

 

[greenjp]

Thanks Terry. I received the part today and got it installed which has fixed the problem. Two of the three push fittings were a bear to release, while the 3rd came off with almost no effort. Installation of the new one went very quickly and without leaks.

I have this exact same Pfister series 26 Murielle faucet. There are two completely different style Spout setups which are very different.

This style uses a long, brass/copper Inlet Line that goes straight through the body of the Spout and out the open end of the threaded tube. This style uses the brass Diverter with the two gray push style connections, top to the Spout Inlet Line, bottom to sprayer and side copper tube IN to Handle hose with push connection. Shown in OP home photo.

Question
My Spout was leaking out the top of the Inlet Line. I bought a new one which screws in using a large hex wrench. This Line is not meant to be screwed down tight all the way or you won’t be able to move the Spout left and right between dual sinks. It is just snug so the Spout moves with some tension. As I move the Spout back and forth it eventually unscrews the Line and it starts to leak out the top.
I noticed the original Line has some sort of sealant or mild thread lock on the very fine threads. The original Line was pretty snug due o the sealant when I had to unscrew it, so this seems to have kept the Line from unscrewing in this application.
Can you tell me what is used on the threads?

——————-
The other style is shown in the illustration posted by Terry and all over online. I can’t seem to find an illustration of my style which causes confusion, because the style in the illustration shows the Spout with the closed end and uses a plastic Diverter that has a very different top connection. The photo here shows the Diverter upside down. It uses a pin to hold it in place when pushed onto the bottom of the Spout.
