Question Vacuum flush in Southwind

our toilet in our class A has a vacuum flush that is very noisy, goes on forever and vibrates the bathroom. It can be heard outside. The toilet will only flush 2x without using it and then it stops going down. Does anyone else have this problem? Camping World says it is fine. Thanks, taberry

If your waste goes straight down into the black tank, you can replace that toilet with a manually operated one and end all that noise.

What year is your Southwind? Is this the VacuFlush toilet with the switch on the wall with red/green indicator light? The manual for the VacuFlush states that typical run time for the pump to reset the vacuum is usually 30-90 seconds...which can seem like forever sometimes. At higher altitudes (usually over 8,000'), it takes longer for the vacuum to reset.

Be sure to use plenty of water for flushing and have a GREEN light, indicating that the vacuum is reset. You should not flush again while the red light is on; wait on the green light.

The VacuFlush should not be "vibrating the bathroom," so if you are not exaggerating it definitely needs repair--that is NOT normal. The VacuFlush is pretty noisy and can be heard inside and outside the coach. If you need a user manual for your toilet, you should be able to Google the model number and find it.

Ours in the Pace Arrow, is quite except the vacume part that only lasts about couple seconds. May have something stuck in it. Had to take ours apart, got a rag stuck in the impeller and plugged it up. DW lost her dust rag, I found it. Took about 3 hours to get it apart and put it back in, bad job, close quarters to work in.

Its a bad idea to flush the Sealand system without vacuum and we can all hear the pump to some degree but if in good working order there should not be any vibration. Sound is sometimes anoying but one benefit is, they use less water than a gravity toilet so you can go a lot longer between dumps. Mine seems quieter with more water in the bowl. We seem to have gotten used to the sound now and really don't notice it any longer but it still can be noticed by others.

It's a 2014 Southwind, thank you for your input, we will just have to get used to it.

2015 Southwind vacuum toilet

Had problems with vacum pump not turning off at higher altitudes. Called manufacturer and was told vacum switches were available to correct that problem. I ordered it for $140.00 plus shipping.

The pump on the Southwind is located behind the storage bin, passenger side,second from the rear, behind a small access panel (18x12). With a lot of bad words and 1 hour, I was able to remove the old switch and install the new switch. Good news, problem solved!

Bad news, the switch I replaced was adjustable even though I was told different. Maybe they ment preset because the new one came with locktight on the threads. The one I replaced, same switch no locktight!

We lined the compartment in our Bounder that has the vacuum pump. Is is quieter and we still hear it pump but we prefer to hear it to insure it is operating.

We made sure to the sound deadening material on the access panel as that is where most of the sound goes to your neighbor.

You need to always flush the toilet with the vacuum or you will create some serious problems for yourself.
