Valve beneath right seat of dinette table

[Vector - Lanham]

My simple question is what does this valve do. It was closed, and i opened it tonight as i'm draining all the water from the system. Tomorrow i'm going to blow out the lines w/ gentle pressure (10 to 15 PSI) and then put in the pink stuff.  Apologies if this is the wrong place to put this, i've been off the forum for a couple years.   All info is appreciated.

That's your black tank flush port valve that you now have in the open position. Here's the Winterization & Storage Tips from Oliver, just curious why would you want to blow out the lines if you're going to use the pink stuff anyway?

[Vector - Lanham]

just blowing out the lines to catch any little plastic shards that have been clogging my filter on my old Shurflo water pump, and probably stressing it a bit.  That's all. I've never used the black tank flush port..is that on the outside of the tank?  i'll have to look. I always flush my black tank out w/ a ton of water everytime i camp, but i'll have to check that out. Thank you rich.dev.

You likely have aerator screens on your faucets and shower.  Removing and cleaning them, and then flushing with removed may improve your water pressure and flow rates.

Rog, was going to do that..but thanks for the reminder. i'll have to write that down.

The black tank flush port "should' be on the curb side behind the axles. Check this video on how to winterize it, and this video explains your black tank flush port.

Awesome, just watched it.  thank you Sir.

The outside Black Tank fill connection is down low on the street side, between the bathroom and dinette window on my 2017 LE2.  Which puts it in front of the axles.

Oh yes @mossemi you are right. Also @Vector - Lanham, it’s on the street side not curb side like I said! Damn I had to really think about that now!😜

Haha yes I can’t even use the excuse of driving on the wrong side of the road up here! I’ll just blame it on Siri!😜

Oliver recommends against blowing out the plumbing system with air pressure. 

As mentioned by Geronimo John above, the best way to clear residual plastic shards is by removing and cleaning the pump filter and faucet aerators.

Just carefully follow the Oliver winterization video using the "pink stuff" and your trailer will be ready for the coldest winter.

Does your 2023 have the black tank flush valve as our older Ollies have?

@Geronimo John

I do not have the black tank valve in my 2020, I believe it was discontinued by Oliver it in in 2020.
5 pumps of antifreeze and done.

Nope not on mine

Like @Patriot said, on the newer models we need 4-5 pumps to sufficiently protect the new flush port system. I remember reading somewhere this change was put in place to meet new codes for the black tank system, something to do with ensuring no backflow of waste water can get inside the water supply line. Here's a pic of the new layout with longer flush system.

@Vector - Lanham: You also may wish to consider disconnecting the toilet water supply line to ensure its a clean/clear and unobstructed run from the supply valve into the toilet - this area can also accumulate the "crud" you experienced in your shower pan and bathroom sink.  Clearing out this debris allows for the desired flow when flushing the toilet.

2023 Elite 1403 is equipped with the black tank flush setup.
