As most of probably know, Vacuflush marine toilets are one of the best on the market. They, however can be very tempermental after time. A few basic maintanence items will help eliminate this.
The complaint is typically that the pumps runs for no aparent reason for a short time and then suts off.
1) Standard maintance on the Vacuflush toilet system is to replace the duckbill valves every 5 years. If your's haven't been or you have purchased a used boat, simply replace them so you have a starting point. The duckbills valves are located at each end of the Sealand vacuum pump or vacuum generater. Simply remove one of the sanitation hoses at a time. Now unscrew the black hose nipples that the hose was attatched to. This is a two piece nipple, uncrew(seperate) them. There will be 2 buckbill valves in each end of the pump. Replace them making sure that they all face the same direction, pointing tword the holding tank or overboard valve. Thighten good and hand tight only. Replace hoses and flush 1/2 bowl of water through. It is a good idea to flush 2 or 3 bowls of water through the system in order to clean it out before disassembly.
In the case a vacuum generater you will need to remove the pump from the vacuum accumulater. Simply remove the 4, 7/16 head machine screws holding the pump on the accumulater and uncrew the white 1 1/2" screw collar from the gray 1 1/2" threaded nipple. The pump will lift off and then perform the above task.

All vacuflush vacuum pumps and generaters pre 2006 use the black 1 1/2" duck billvalve. In mid 2006 Sealand put out a new vacuum generater using 2" duckbill valves. This vacuum generater is designated a "J" series pump. The pump is white and only has 1 hose nipple on the pump. The second nipple runs down the center of the pump. If you are confused as to what you have, simply know that if your's is pre 2006 you use an 1 1/2" duckbill valves. Mid 2006 and newer the pump will say "J-W" series on it. This is a 2" greenish duckbill vavle.

tryed to flush, bowl fills with water, but will not empty, pump is running. Had to cut wires to pump, could not turn off.
Sounds like the toilet is plugged. "The system will operate normally but will not flush" is a plug symton. The pump is drawing vacuum against a plug and shuts down. It does not know weather there is an obstruction or if it is drawing vacuum against the flush ball.

My vacuflush toilet was working just fine till today. I tried to flush the bowl but it will not flush. The vacuum pump its working but it doesnt stop as usual. Even if I wait several minutes it continues working but there is no vacuum at all at the toilet!! I had to shutdown the pump´s power. I´m wondering what happened !!
I have a vacuum leak problem in which the pump will routinely run avout every 30 to 40 minutes, pumping for about 10 seconds each time.
I have replaced the 4 1/1/2" duck valves, and have replace all seals, flush ball, and shaft on the tolet.
Still - no change what so ever.
What else is likely to be causing the vacuum leak?
vacuum leak causing pump to run every 30 to 30 minutes for about 10 seconds each time.
Have replaced duck valves and seals, flush ball and bowl seals - but no chage, no improvement.
What else could be causing this vacuum leak?
I have a 1993 Sea Ray 330 express cruiser. The vacuum pump quit working all together. It was working fine then the next time i tried to turn it on nothing. Any suggestions?
Here is my situation: When I try to flush the water does not go down. Breaker switch for head pump keeps flipping off. No power to the gauge that tells the level of the tank either.Any ideas?
VacuFlush is a 2000 model. Pump circulated every
10 or so minutes. Ran for about 12 seconds. It wore out the Bellows in the pump so I had a Vacuflush (schooled) tech replace the pump & motor with SeaLand Pump SW12. In doing this he noticed that a Collar on the Model VG pump was cracked so he replaced that also. Upon completing all this he check the head with some a vacuum gauge and all seemed to work OK.
Within 6 hours the pump started to cycle again. The tech said this was not uncommon in that the new pump & tank create so much more vacuum than the system has had for some time that it causes other old parts to fail.
Do you have any suggestions as to what I might check next?
Thanks

flush toilet and pump would not shut off
and it isnt clogged
I'm working on a 2017 boat 3 weeks old. With the vacuflush at the moment I'm not able to flush the toilet in all 4 rooms they all have the red light showing. I have gone to the engine room multiple times to look at the pumps there is power but no vacuum at all. In the master sweet I had to clean the toilet out of toilet paper and so on but still no operation. Any suggestions of how to maybe reset the system I have blacked the boat out 3 times still no change.
Can you replace a s series vacuum pump with a t series?
