Shower not draining
i have a 2015 Montana 38' My shower is not draining.
I had the trailer pumped a week ago and haven't used it until yesterday- I wasnt here so I can't guarentee that the grey water waste valve as completely pulled during the draining so there is that -
I have snaked the drain and it seems to be fairly free - the sink next to it drains just fine
Is there something else that need to be pull/pushed/tested? I have had this RV for 2 years and this is the first time i have have this problem
Thoughts are appreciated!

The shower has a Hepvo valve. That's a bladder like rubber thing. Snaking it didn't help it at all. You're going to have to go underneath and remove it. Either fix the bladder or replace it.

Thanks for the information - I am assuing i need to go under the shower and replace the valve? I may just take it apart and make sure there is antifreeze in the tank and fix it next spring.

Here is a screen shot from a YouTube video of a guy replacing his hepvo valve on the shower drain. Hepvo valve is circled in red.

Our Hepvo valve is plumbed straight down at the drain. We were gone a couple weeks and got back last week. Took a shower the next morning and the water wasn't draining. Stomped my foot over the drain and got the membrane to open up and the water started draining.

I thought snaking a hepvo valve damaged it

The HEPVO valve has a soft membrane that closes to prevent sewer gases from going back up into the trailer. It replaces the traditional "P" trap that is normally filled with water for the same purpose in places where a "P" trap is not practical or won't fit.
You are correct that if you run a snake through it, it will most likely damage the membrane and need to be replaced.

This week our shower began to develop a slow drain. I used a leaf blower placed directly over the drain to force water through the hepo-valve. Drain has been flowing normal as when new. It’s an easy option to try first.

Have you tried a simple toilet plunger and see if you can break it free?

They stick shut if not used regularly. A plunger usually works. If not you'll need to open the basement access, locate and replace it.
