Replacing Duckbill Valves + Vacuflush System Overview, Sea Ray Boat

Shit happens… 😂 thanks for the DIY !

Good job Paul. Wow, that disclaimer had me thinking there would be flying brown corn or something ! Cheers 😎

Mate, I'm looking forward to watching this! You're history of videos on vaccuflush systems and duckbill valves is second to none. I have used the other ones to diagnose issues on my boat with vaccuflush. We have 2 systems on board our Maxum 4100SCA that look identical to yours. One works fine and is easy to access. The other one in the aft stateroom clearly needs new duckbill valves but I'd have to be a scrawny small person to access it and I'm still trying to figure out how to get in there to fix it. Thanks for great crappy videos. Cheers, Graham in Oz.

Thank you I need to do this on my 330. My buddy has the 370.

Another great "How I did it" video Paul, thanks. I know you have done this before, on previous boats. My vacuflush toilet seems to be working just fine, but...I have never replaced my duckbill valves and I was wondering what signs you experienced that let you know they needed to be replaced?

You forgot the don't lick your fingers warning 😂😂

Wear gloves when doing shitty jobs! Lol. I would further recommend to change out the duckbills anytime one has to fart around with taking the vacuflush apart. We've got a 2000 340, new to us 2 years ago. First we changed out the complete internals of the toilet rather than replacing the broken pieces ( too shitty of a job as it's not our shit yet, lol). Then we replaced the pump's bellow as it was cracked. This year we had to do the duckbills. I wish we did them last year when it was all apart. Life on the learning curve I guess. Now a lot of our boater friends want us to look at their shitters, lol.

I’m surprised you didn’t replace the bellow/diaphragm. Mine ruptured this summer. I was horrified when I saw the mess.

The vacuflush on our boat was replaced in 2022. How often should the duck bill valves need replacing or will the system performance just drop when they need done?

We dove in to replacing the valves in our SeaRay 260-05 yesterday, had a hard time even reaching and managed to find and change merely one.. when watching this excellent video on that we’ve come to wonder, are there always 2+2 or how many did you just replace? 😮

Great video Paul! Very helpful to us novice boat mechanics. I've noticed many generic replacement duckbill valve options on Amazon that are much cheaper than the Dometics that you recommend. Have you had any experience with the generic replacement valves? My initial thought is that they can't be worth a crap if they are priced $18 for a 4 pack when Dometic is $60 for a 2 pack.

Big up for no gloves shiet poking!
