"Larden" dump valves appear to be OEM in my 1990 Excella

[sbrianericks]

I need some help, friends. I purchased this 1990 Excella a couple of years ago knowing I would need to replace the dump valves at some point (damage from a tire blowout with previous owner).

I cut the access pan, dropped the valves, and they are "Larden" brand. One of the extension rods is missing (it would probably need to be about 11"), the other is about 17" long, non-threaded. The valves are the press fit variety, so do I just order new Thetford press fits?

They have a 1989 date on them which makes me think they were probably installed new with the trailer, but I can't find any info about them here or elsewhere on the web.

Any wise counsel? Thank you!
Brian



Thanks!

My 93 had Thetford fittings. I replaced them with Valterra which no is much more common.
