How to Replace VacuFlush Toilet System Duckbill Valves on a Boat
Vložit
- čas přidán 17. 10. 2020
- If your boat VacuFlush head pump keeps running (and there's still water in the bowl) then you probably need to replace the duckbill valves by the pump. This is a bit of a nasty boat project, but not as bad if you follow our how-to where we replace the duckbill valves for our Sea Ray aft toilet system (common problem, parts and repair for on most boat brands!)

Thanks heaps for this great video! Definitely removed the mystery about replacing these mythical creatures, the DuckBill!
Oh you are SO welcome and thanks for watching! Captain Brian is good at breaking it down with his how-to videos! It’s a dirty but necessary maintenance job & once you know how to find them not too difficult to do yourself 😉
Thanks for doing this - very helpful, and I’m now quite comfortable with doing the job myself. Cheers
You are so welcome - glad it was able to help you!! 👍😁
I did’n now how the system was working. Thanks of your clear video it was really easy to replace at our Sunseeker Camargue 44. Thanks, Karel from Belgium
awesome - glad it helped! Hello in Belgium ;)
That was a fantastic tutorial , really appreciate you taking the time to post it. We are about to give the 10 year old Vacuflush 5009 in our Unimog Overlander a service so this has helped so much 🙂
You are so welcome & thanks for the comment! The good thing about older boats is there’s always opportunity for more fix-it videos! 😁Hope your project goes smoothly.
Brilliant help, thank you!
Just changed ours and they certainly needed it. It took less time than watching the tutorial, all thanks to your help. Thanks
Awesome so glad it helped & thanks for the feedback!! That’s a job you’re definitely happy when it’s done! 👏
Thanks for making this video. Helped a lot!
You bet!! So glad you found it helpful 👍
Really well done Bill. One of the better videos
thank you so much - glad you found it useful! Also it's Captain Brian, not Bill, but it is a duckBILL video LOL :)
Thanks I’m really glad I found this channel. The diy is the part I am most interested in, easy to follow video and audio and detailed. I would have changed the other duckbill while I had it apart odours aside , but then never having done one maybe my bravado is misplaced 😁. Will now go in search of your other diy videos
Awesome - so glad we could help! And thanks for following along, been busy boating this summer and catching up with more diy videos soon 🤗
Really good video! We followed your steps and changed our duckbills for the first time :D
Awesome - so glad we were able to help! 👍
Perfect, Thank You!!!
Thanks for watching & glad it was helpful!
Helpful video. Thanks for sharing!
Thanks for watching & glad you found it helpful!! 👍
Excellent explanation, recently replaced mine as well as the head seals.
Thanks! Head seals are the other common thing to go for sure. It’s a 💩job but somebody’s gotta do it! 😂
Thank you for the wonderful step by step. You did a dirty job so well
Thank you - appreciate that!!
Thanks. Mine keeps recycling so with this video as help I'm going to tackle the job. One rule on my Searay is no #2 so hopefully it's not too gross!
Great - hope it helps you out! Its really an inexpensive fix and common issue. And yes, we had that rule too before kids came along.. when they gotta go they go LOL
I tried that same rule... but grandkids always seem to trump me....
Thanks for this; tackled the job on my 17 year old searay 320 yesterday. Original duckbills didn’t look too bad! I also only replaced the 3. Hardest part was some access and gloves that broke! Personally I never use the head; only the admiral and occasional guests- because I was dreading it! Also..I did lose one of those tiny screws….
Glad this helped you out Jon! Sorry to hear about the glove break & losing the screws ;( Its not too bad of a job & luckily you don't need to do it too often!
Really really helpful. Thank you!
Glad it was helpful- thanks for watching!
You da man. Thanks for the upload
thanks man - appreciate it!
Thank you for that info.
You bet good luck!
Thank you
Happy to help! 🙌
Fantastic! Thanks for doing that. Now I know what's wrong with my forward head!
Awesome so glad to help! 👏
Yup! I'm next. We just got the boat in the water last Saturday and it failed immediately upon testing. Our retrieval was interesting to say the least. I'll post it by tomorrow. Thanks for this "tutorial."
Yikes! Well better to replace now before you are too far into the season!
@@MyBoatLife actually i was able to troubleshoot the issue and get it working again. I think it just needed more water flushed through the system. Seems to be running like it’s supposed to right now.
@@eternitysshore good to hear! If the pump runs sporadically after it’s been flushed & gone through it’s cycle then it’s your duck valves.. if the bowl is not holding the water/vacuum then it’s the seal at the bowl. Usually one or the other!
I’ve just replaced my Vacuflush duckbill valves with a TMC electric macerator toilet and new pipes. 😊
Sounds like your head gets a lot of action - if the vaculflush toilet system doesn’t work for you I don’t want to know what you’re eating! 😂
Very helpful with my 320; most difficult part was access to one of the back bolts and also didn’t get to the 4th bill as I didn’t want to break anything. My boat is 17 with original duck bills; they actually didn’t look too bad. personally I never use the head
Good to hear! Yes, 3 out of 4 will do the trick ;)
Great! Thanks.
You’re welcome.. thanks for watching! 👍
Thanks for the great video. Pretty sure I can do this now. My only problem is accessibility and I have two of them. 🤨
You are so welcome - it’s really not that hard to do. But yeah, sometimes squeezing in to get to them is the biggest challenge. 🙄
Thank you Sir, I need to do mine this weekend, you made it look easy, lol! What size did you use 1.5?
Cool glad we could help! We use the standard Dometic duck bill valves - there’s a link in the description to exact ones!
Exactly what I was looking for. My pump runs continuously, and wont build up pressure. I am hoping this solves the problem. Thanks again.
Yep most likely the problem, especially if they haven’t been changed in a few years. Good luck & hope it goes well for you! 👍
Ty. My pump won't shut off so your info will be put to use after work and a trip to the parts store.
Great glad to help & good luck!! 💪
Capt. I have a 2018 Boston Whaler 270 Vantage. No voltage info available for the VacuFlush like on the boat in this video. When I turn on my pump it makes a really loud screeching noise as it primes. Once it's primed, it's fine. Then when you flush it does it again. Any idea what this could be & if there is an easy fix??? Like sending oil down the toilet LOL??? Glenn
Hi Glenn, So when you flush, a motor moves an arm up and down to make the bellows plunge up and down (this is all on the pump in the bilge). I can only imagine that screeching would be coming from the motor or the arm. I found some screws loose where the motor attaches to the arm and that was making some noise, I tightened them and it quieted down. Maybe yours are too tight? Take the white cover off and watch it pump, maybe you will see/hear what’s wrong.
I saw what appears to be teflon tape on the backside male fitting. Is it suggested to use..or overkill? Thinkin it couldn't hurt. Great video..and thx much!
I don’t think it’s necessary- fittings are all plastic and fit pretty tight. If it was in there it was probably leftover from another time, so couldn’t hurt. Thanks for the feedback & glad you found the video helpful!!
Thanks , very helpful . But can you tell me what size duckbill valves you used? I have a 2001 453 Silverton I just need to make sure before I take it apart. I have the same VacuFlush Sys.
We used 1 1/2” duckbill valves which is a standard size. Link to it is in video description too! 👍
@@MyBoatLife Thank you sir, helps and saves me a lot of stink.
nice video. question for anyone... if our vacuflush toilet IS NOT flushing... is it the nearest hose or hose closest to the fiberglass wall that I would replace?
Hmm not sure may be best to try both… or a plunger? Btw if you plunge it’s safe to plunge down but not up - slide sideways to break the seal of plunger. Plunging up will suck duck bull valves backwards! 😣
Captain Brian, can you assist with the parts to order, are they standard? I think we need to replace duck bills, bellow and gasket, I cannot find any part numbers online or even the model of vac u flush in my manual. Am I over complicating it? I see parts on amazon, Bellows, gaskets and duck bills sold together. 1998 370 SeaRay Sundancer.
I think I just found my answer, found the amzn link.
Yep - the duckbill valves we use are linked in description! They are pretty standard. Good luck with your replacement!
I just changed mine but the lump won’t stop running. The bowl is Sealed. Please help
Never ever stops? Or stops and then starts again later?
If it never stops, it could be a bad vacuum switch on the pump. If it stops and starts there’s a slow leak somewhere else like the seal on the shaft where the foot pedal goes into the base of the toilet. You should be able to hear a hiss if it’s that seal. Hope that helps!
Whoop!!
😂it’s a fun job!
Haaa🤦🏻♂️ we have had that happen 3 times now... the main time was 4 of July in a busy town, we didn’t know/hear the pump was running little while later we heard it and looked in the engine room and the diagram had cracked and let the waste come out🤦🏻♂️🤦🏻♂️🤦🏻♂️🤣 long night that night.
Oh noooo!! That sounds like it was a real mess... ewww!!
You should have replaced all 4 you were right there and its not difficult. Also I would have pulled the Bellow out cleaned and inspected it, a replacement Bellow coast about 100.00 on E-Bay.
Yeah I was worried about tearing up the threaded piece trying to take it off
Yeah I get it but if you ever do it again mine came off easy I just did it and its 1999 SA DA 290 and I checked the bellow and it was fine. Looking forward to another season here in the western basin of Lake Erie. If you are ever around here go to Put-in-Bay you will not be disappointed.
Thanks good to know! And yeah would love to check out Lake Erie some day - sounds nice. Countdown begins... just a few more months ;)
What a shitty job - lol. Great video
Got that right lol! Glad you liked video 😊
3rd video I watched where the 4th valve is skipped...because apparently no one knows what a strap wrench is???
Maybe.. or a rag & pair of pliers- just didn’t want to risk breaking it and 3/4 works
What a crappy job :-)
Ha ha yes it’s the worst but someone’s gotta do it LOL! 😂
Fantastic, but what a lousy invention, in terms of maintenance. WackoFlush.... Normal system without the vacuum works just as well, without the maintainance hell......
There are a lot of advantages of the vacuum- it takes it away quickly & keeps fumes from coming back to the toilet. We’ve had boats without vacuflush and let’s just say it wasn’t always pleasant. Maintenance is not really that big of a deal to change the duckbill valves - only had to do it once per pump on our boat in last 10 years.
