FWIW, I have hard water and minerals build up on things over time. I drop the parts in vinegar for a few hours and wash them off, works great.

[valis]

if it's the diverter, wouldn't the extra pressure then be sent to the spray nozzle? And why would it run fine for a bit and then ramp down?

But the diverter is as good a place as any to start, especially as it's only that one faucet. Wonder if you run the sprayer if you still get volume to the faucet.

Well I took the diverter out, it was about 6 inches in length. It screwed in, I didn't have to shut off any water, because it was at the spout. Worked out good, but the problem still is there. I cleaned out the diverter. It was on about 5 inches of about 1/4 brass, then a round adapter on top with a "diverter" on top that pops up when I blew into it. I cleaned it out the best I could, It seamed clear. The diverter popped up easily. I then opened up the faucet a little with the diverter out to let some water out, maybe I'd clean it out. When I put it back in, the water did come out fast at first, then slowed down again. In fact, it splashed so hard on the sink bottom, it came over the top of the sink. No one in my area had a diverter for the American Standard #4251 Faucet. I guess I'll order one on line. I checked everywhere. Even plumbing places. For now, I guess, I'll consider this case closed, I think I've pin pointed it to the diverter.

Where abouts do you live in MI

I might be able to find a supply house for you

I am not sure what changing the diverter would do? I would think it would be something to clean unless it is a sealed unit.

This is the only faucet which does this in the house??

You did look underneath to check and make sure the hose did not get caught on something and crimped I assume?

How about the sprayer... Does it do the same thing?

Sorry if these have already been asked and answered

[silverado4]

No, nothing is "crimped", I checked. Both the hot & cold are running slower then it did then when it was first installed. I live in Trenton, Michigan, Next to Woodhaven 48183.
I was told there is a good plumber supply house on van born near telegraph, but I can't remember the name of it. I'm even thinking of taking the diverter out, and trying it to see if the water pressure is higher then with "no" obstuction at all. The sprayer line isn't kinked either. It's in the main valve at the spout, I'm sure.
Thanks for your help.

How long does it take for the pressure to decrease?

Does the spray do the same thing??

I will check with a plumber I know that and see what he has to say and if he knows any supply houses near you.

We live north of Detroit so not familiar with anybody in your area

[silverado4]

Sorry I didn't get back sooner,
I removed the diverter, it was about 6 inches, I turned on the water, I had high pressure without the diverter, so I think I have it pinned down to the diverter. The top of the diverter is soldered to the brass fitting, it appears it is a screen or something like that. Water did come through the diverter when I had the spout off, but I could not turn it on high without getting water all over. I put it back on, same thing, slow, but it doesn't seem as slow now.

got a way to take a picture of that diverter? maybe there is a way to clean it.

my plumber buddy does not use American Standard so was no help.

I will see if the supply house we deal with would consider selling to you. they are wholesale but maybe they would consider it. they are not in your area but could ship it as they take charge cards.

[wacor]

Well the supply house I deal with does not handle American Standard.

But they said to check with this place which does sell to the public. He said they can usually get any faucet part you need.

Just be sure to have the model number of the faucet and if that print you had indicates a part number that will make it easy for them to help you out.

they are not in your area but they take charge cards and I would guess could ship it to you..

I'll take a picture of the diverter maybe next week for you,
the part number A952026-0070A, If you look at my picture of
the parts list earlier, you can see it looks like it's only about
1 inch, but it's about 6 inches. That's a bad diagram of it.

[JohnWill]

FWIW, for mineral deposits, just dropping the part in vinegar for a day will dissolve most of them, I do this regularly with faucet parts here, we have very hard water.

[silverado4]

Good point on the vinegar, maybe "CLR" will work also, I'll give that a try in a few days.
Thanks

[silverado4]

You won't believe this. I just happened to call "American Standard" the maker of my faucet, and gave them my model on my faucet and told them my problem. The girl said that this particular faucet had a "life time" warranty, and she is setting up a warranty for me on my problem. When I told her my problem, she said it sounds like your diverter is bad, and she'll send out a new one free of charge, "including" shipping. I could not believe that even shipping was included. Well now I just have to wait for the part and try that out. It should be here in about 7-10 day, or around April 26. I'll keep you posted. Wonders will never cease will they.....

[wacor]

Good companies stand behind their product. I was not aware they had a lifetime warranty.

[silverado4]

Well, it's fixed. The first diverter came in, but it was in pieces. I called american standard, and they were sorry, and sent me a new one. It must have got damaged in shipping. It arrived in about 10 days. The faucet I found out on line, had a life time warranty. When I called about my problem, they knew exactly what was wrong. When the diverter came in, I took the old one out. According to the parts list, it was a small diverter, but when I took it out before I ordered it, it was about 6 inches. It didn't match the drawing (see previous drawing). The reason for this was that the diverter was suppose to come out of the "adapter" it was screwed into. It was in so tight, that the adapter came out with it, that's why I thought it was so long, and the diverter covered the threads, and I didn't see the threads. Anyway, after I finally got the old diverter out, the new one would not go in. I used a tap to make good threads in the adapter, then the new one went in easily. Sure must have been a lot of junk in that line. The faucet is working great now, when I use the sprayer, the water shuts off completly now, it didn't before, and the sprayer takes all the water. Thanks for all you help in this matter. I installed it yesterday.
Thanks also to American Standard for standing behind their product.
Silverado over and out.
