Question:
Does the T58 have a seal on the swivel side. I installed it and when dumping it has a steady drip. Do they offer this without a swivel connection. it seems to me that both sides could be rigid twist connections and you could orientate it to the desired position but I assume the swivel is for places that have a tight clearance which is not that common anymore. Thanks

Welcome back Jeff. The Valterra Waste Valve item # T58 has a O-ring or rubber seal on the swivel or bayonet hook side. It is indeed offered without a swivel connection with the Valterra Waste Valve item # T50A.
The Valterra Waste Valve item # T50A has a 3" spigot that installs onto your sewer pipe with ABS sealant like item # A05-0303. The other end has a 3" Lug fitting to attach a bayonet style sewer hose.
We also have the Valterra Bladex Waste Valve item # T40D that has 3" FPT and MPT end threads on the ends.

Do you sell the O-ring replacements? I am more interested in the valve being twist-on for both sides without the swivel. The swivel just leaks over time and only serves a purpose for tight locations. The dual twist-on would make it much easier to replace when the valve goes bad. I’m not interested in the glue on or thread on versions and I would assume most folks aren’t either. Thanks- Jeff
