How to remove the corroded valve seat housing in my tub faucet

Grrr.plumbing ... I am the by default female ''fixit'' around here and this is my plumbing stumbling block .I have 30 year old American Standard (not!) 3 handle tub faucets (shower diverter handle in the middle )I am adept at replacing valve seats and stem/washers assemblies, but my cold water valve seat housing itself has corroded through, so the faucet continues to drip around the valve seat.How do I get that piece out ? It is threaded, as is the stem housing (with a hex lock lug to hold the valve stem in place) Is there a specific tool to remove that?

Some seats ae rremovable and some or not Some take a hex(allen) wrench and some take a square (seat removal tool)  Most of us use a seat grinder. (another tool to dress up the seat (Remove material) past the seat damage. You will find any of these tools at any hardware store that sells plumbing parts. If the seats have a square or hex hole remove and replace rather that grind(dress)the seat. All right hand threads meaning turn counter clock wise to remove. Take old seat to the American Standard plmbing supply outlet and then will match it up. Good fix-in to ya.

    Very frustrating. I used the seat removal tool, but the seat just crumbled into fine bits of brass shavings under the pressure of the tool. Seat didn't budge a bit even after soaking in wd-40. Another site said there is a "Faucet Seat Sleeve" that fits firmly over the valve seat to deal with this type of problem. Further in this same article it said if seat is stuck, take off the entire faucet assembly and replace entire faucet if its other components are worn/damaged. I take it the faucet assembly is all the piping inside the wall, and I'd rather not deal with all that until we remodel the bathroom. I'm hoping I can find the Faucet Seat Sleeve and that it will work until then. I certainly wasn't expecting this type of problem...

Why is there Rust from tub spout and shower head

When you turn off faucets other than your tub or shower you will note that the water stops fairly abruptly. Not so with a shower head or tub spout. Some water always dribbles out even after you have turned it off. This small amount of water then evaporates leaving behind the iron that was dissolved in your water. This also happens if any faucet has a slow drip. There are products that will easily remove the rust stains. CLR, Iron Out, or Iron Ike are all good products that will remove the stain. Available at hardware stores, plumbing supply houses, and, ugh, Home Depot or Lowes. Please support your local business owners by purchasing there.

Dripping facet

If a faucet is leaking the necessary repair will be either:
1. For a ceramic or washerless faucet, replace the cartridge.
2. For a typical old fashioned faucet, open the faucet, replace the washer (and packing if it has any) and verify that the faucet seat has not eroded.
The newer washerless faucets cannot be repaired except by replacing the cartridge. Cartridges for most common faucets are available at most home improvement stores or plumbing supply houses.
It sounds a lot more difficult than it really is, just shut off the water (usually a shut off valve under the sink). After the water is off, remove the handle and any chrome protective covering. Depending on the faucet type, it may be a little difficult to remove the cartridge since they are often covered with mineral build-up or corroded into place.
Once you remove the old cartridge the new one usually goes into place easily.
NOTE!!!
For single handle faucets, make sure you put it in the right way, some of them will put the hot to the wrong side if you put them together backward.

I have a Sterling tub & shower faucet that is about 25 years old that is leaking. I have replaced the seats & stems but it still continues to leak a small steady stream out of the tub spout. The...

Your fixture body may be corroded beyond repair. Since you've replaced all the rebuildable parts, I'd suggest you get a plumber to check it but expect that you'll need to replace the faucet. Get a modern "cartridge" (Delta, Moen or Kohler) fixture that can be easily repaired indefinitely.

When faucet is fully closed hot water keeps on leaking.

You need to replace the valve stem. Turn off house water, locate and loosen handle set screw, remove cylindrical cover, and remove retaining nut to access stem. Take e stem with you to a home store or plumbing supply house for accurate relacement.

How to replace all the valves hot ,cold , diverter

If you don't really want to tear into the finished tile, you could repair this units most likely. You will have to shut off the water in the house. Remove all handles. Loosen large nut assembly and unscrew the valve stem. If you remove the valve stems you can purchase the complete assembly at a full service plumbing supply co. If the seats are not removeable, a reseating tool is inexpensive. Replacement knobs are available if they are unsightly. The replacement will require removing tile, drywall, cutting or de-soldering piping. Purchase a new valve and follow directions to install. Home depot sell Price Pfister faucets.

I have a older Delta shower head/tub combination with scald protection. It leaks from the tub diverter. Where should I start?

I'm assuming that you have a three handle faucet. You need to remove the diverter from the faucet body and while your at it remove the hot and cold stems from the valve body (the parts are inexpensive). Remove the seats inside of the valve body towards the back, replace with new ones. If stems are in good shape, just the washers and seats need to be replaces. If the brass on the diverter or on the hot or cold stems is pitted or marred, then replace the whole thing. The parts should be readily available at most plumbing supply places.
