'92 Jayco faucet parts?

OK, I think mine were Phoenix.

I replace mine in our 2004 Jayco. I took out the old went into ACE and for about $30,00 got a replacement.

There are two major brands that were around back then- Utopia and Phoenix. The new Utopia replacement cartridges look almost the same as the older ones, but are not interchangeable. The old ones have an O ring as a washer, new use an actual washer. Phoenix could be plastic washerless cartridges or brass, which can be rebuilt with o rings and washers.

Best bet is to take the cartridge to a good hardware store, or an RV dealer.

I had a 93 Jayco up until recently. I rebuilt the faucets within the past 5 years. The parts are out there. I can't recall the brand, but they are an RV brand used by OEMs. Search RV faucet parts on google and see if that leads you anywhere.

1992 vintage....are the faucets even rebuildable. Typically the RV faucets are not.

If you can disassemble....then take old parts to ACE Hardware/Home Depot/Lowes etc. and see if you can match up with Delta/Moen/Price Pfister

If you can't disassemble OR match parts..replace with residential faucet that can be rebuilt later on

Home Depot? But many replace the fixtures with modern ones from the same source. Be reminded that generally the fixtures are put in place before the sinks go in in the beginning, so it can be a real pain to replace something that you cannot see or sometimes even feel.
