Vacuflush Pump on Timed Relay

YYZRCYYZRC Georgian BayMember Posts: 4,053 ✭✭✭✭✭
Looking for a wiring diagram for my 140 series Vacuflush. I plan to add a momentary switch on a timed relay to control the vacuflush pump.  This way, I won’t have to worry about a vacuum leak causing the pump to run excessively.

The cut blue wire is interesting. Rinker wiring at its finest  :#

    How is that going to work?

    @YYZRC I'm not sure what you mean by leakdown.  Are you saying the vacuum pump runs too often?

    Yes what are you controlling?

    Sometimes hair or other debris gets caught in the loo and it doesn’t seal. The vacuum slowly leaks and then the pump runs. I always shut the breaker off at night and when not at the boat for fear of the toilet losing it’s seal and the pump burning out. 

    By adding a momentary switch and timed relay, I eliminate the risk of pump burnout as the pump will only be powered for a defined period of time after the momentary switch is pressed.

    I have always turned off mine along with the water pump and hot water heater when leaving the boat. I can normally hear the vacuum pump except when the engines are running. Let us know how it works out.

    I do the same when I'm off the boat. I also try to remember to turn off those same breakers when underway.

    For me and the Admiral it's not big deal to deal with the vacuflush breaker but I'm training a 7 year old first mate as well.  I've woken up in the middle of the night to the sound of the vacuflush pump running because he didn't side-step the pedal enough or some toilet paper got caught or...

    Fully understand, had a 3-1/2-year-old on board one weekend who used the toilet often on her own, so constant monitoring.

    good thread, following it.....VacuFlush is pretty slick when it works well, haven't had any real bad experiences with ours. 

    Bought our brand new 246BR in 2007.
    My little daughter dropped a finless brown in the porta-potty within 15mins of leaving the dock. FFS.

    I count myself as lucky.  In 10 years, I had maybe once or twice that the pump wouldn't hold vacuum overnight.  The only maintenance I've ever done was wiping the flush ball with a Clorox Wipe.

    My first mate takes dumps bigger than his arm and uses a whole roll of TP.

    In the summer I had a feeling the duck bills were about to fail and sure enough on our last day of a 9 day trip they did. Luckily we were on a lock wall with power and water. I had also watched the attached video before leaving on the trip. Payed off because I would have been struggling with the 2 on the right , knowing to remove the 4 bolts holding the pump to the tank.

    You better keep praying to the porcelain gods!! :smile:  My first trip owning this boat I found out where the duck bills where (disgusting enough, but when it's a "new to you" used boat, well...).  Even worse, we were on a 10-day trip in hot July and no spare duck bills to be had.  Spending all that time removing ice maker and crawling in there only to "clean" the old duck bills so it would work the rest of the trip.  yes, I always have spares now!!  I have a sign in my head that states "If you haven't eaten it, then it does not flush".  Our head gets a LOT of use and I've made up for all of LaRea's years of not having to mess with his vacuflush.  I've tested my vacuflush to actually hold pressure the entire winter!! (so far this year it's been holding for 4 weeks)

    @Dream_Inn Impressive holding power!

    I did the duckbills, bellows, gaskets this summer. Synthetic grease, etc.
    Water stays in the bowl. Still have a very slight leak somewhere.

    Interesting maintenance job - didn’t mind it at all.

    I'm in the same proverbial boat as @LaRea in terms of zero maintenance, but I'm sure my time is coming...

    No vacuflush, electric pump head, one seal kit since new.

    Seems vacuflushes are great - until there is an issue.

    Also replacement parts are much more expensive than other systems

    VacuFlush does make a cool sound tho. Worth the extra $$$.

    Got the timer and switch wired up. Now just need to cut the power at the pump and run it to the switch and back. 



    Here’s a pic of the circuit. The timer works slick.
