I've been trying to find the toilet seat and cover from American Standard Williamsburg P/N 5395.700.020 with no results. I even called American Standard and they gave me a phone number and a site that did not exist anymore. I would like to have the replacement part or an alternate part.

General Plumbing Supply has always come through for me...

Yelp only gives them a 3/5 but I have always had to wait with PROFESSIONALS to get my turn. I'm not big on ambiance when hunting for obscure plumbing parts..

BRING your old (always... any-parts) seat with you!

Amazon says $34 (plus tax)... Phenomenal return policy

A quick search on line yielded lots of other choices...

Happy hunting!

Try coating it with Vaseline prior to putting on. This seems to help with rusting.

American Standard is the brand, so you've got a start there, but 1.6 is a flush measurement. Look around the inside for a tank for a model number - with AmStan toilets it's usually a four digit number beginning with a 2 or a 4. This will be what you need to get the OEM toilet seat. However, since toilet seats are purely cosmetic (they don't affect the functioning of the toilet), you can literally take a few measurements and find something that simply keeps you off the porcelain. http://www.plumbingsupply.com is a good one for toilet seats, btw.

Well, something is amuck with the valve. What you do is jsut replace it. The plastic gets brittle, eventually.
There is also a chance that the shut off valve washer is causing issues. If the problem persists, look into that, also. The washer sometimes shrinks and will not remain open. It is an easy replacement fix.

Your toilet is still offered by the manufacturer:

Did you try calling or emailing the parts dept. at american standard? I am not sure if they just sell the gasket. American standard parts are certainly different from most toilets. I looked on ebay, not much for american standard toilets. Were you able to remove the four screws and get the sealer under the gasket.? I will do some more research for you and try to find parts. take care, andy

If it doesn't embarrass you, you could take the two nuts off the bolts holding the seat on, put the seat in a bag and take it to a Home Depot or Lowes or Walmart etc and match a new one to your old one. Good Luck
