What size grey tank dump valves?

[greysailor]

Howdy all,

Finally got things repaired/modified/squared away enough on the new RV to take a little shakedown trip. I noticed that there wasn't as much flow when dumping the grey tanks as I had on my former motorhome. It had a 3" drain from an 80 gal tank, so it really flushed out the hose when emptying. Do the Creeks possibly have smaller dump valves leading to the main drain tap? Maybe I need to drop one of my Flomax pills down the drain!!!
Thanks

I noticed the same slower flow on our 34RLSA also.

I mentioned it to the dealer to check while in for warranty work. They told me the gray line is smaller... I don't remember what size they told me, but it is smaller than the black drain.

Thanks Sid,

I was hoping that it was smaller lines and not construction trash in the tank...

X2 - Mine runs slow also.

The gray water drains on our 34RLSA appear to be 2". Lot easier to work with than 3 in.
