Draining ClassACustoms freshwater tank with 1.5" drain hole

[kellin]

Hey guys,

Not sure if anyone else here has run into this issue with their ClassACustoms freshwater tank. The tank they sent me has 4 openings, two 1/2" openings (for air vent and line to water pump), and two 1.5" openings (for water fill and water drain). I would like to be able to drain the tank with a hose, but I can't seem to find a fitting that reduces from 1.5" to a 1/2" fitting for my pex line to go into. Does anyone have a suggestion for what fitting to use or have any experience draining another way? I am looking to run the drain line out from the water tank to the rear emergency exit.

Thanks a lot.

Shouldn’t you be able to find a barb fitting like that? Or a bushing

Sounds like you're already using the half inch opening for supply, so the only thing you have left is the inch and a half opening, correct?

There's no single fitting that does that to my knowledge, but if you want to completely drain the tank consider an inch and a half plug with a half inch NPT opening at the bottom of the plug.

Use reducing bushings to get from the 1.5" to .5" FIP then a .5" PEX-MIP.
