It's an excellent toilet...but--
they're a LOT more expensive than they're worth.I had one on my last two boats. When I installed it, it was the best toilet on the market. However, in the last few years there have been improvements in macerating electric toilets that have resulted in much better toilets that can also use fresh water--and very little of it--and fewer amp hours for considerably less money.The VacuFlush doesn't macerate...waste is sucked through the system by accumulated vacuum when that vacuum is released. That splatters waste in various size pieces all over the inside of the hoses and vacuum accumulator tank. The highly touted one pint of water isn't enough to rinse it out, and the flush water flow is so weak that flushing longer doesn'taccomplish much either. So unless you fill the bowl completely a couple of times and flush that through at least once a day, you'll not only have permeated hoses in a very short time(only took two months on my boat), but if you're lucky enough to avoid that, urine crystal buildup in the hoses that can reduce the diameter to less than an inch in a year or two. There are several macerating electric toilets which offer a fresh water solenoid option and use as little a quart per flush...or even a "dry bowl" flush, something the V/Flush cannot do.Macerated waste is liquid, and the water flow behind the bowl contents completely rinses the hose.All the parts of macerating electric toilets are contained in the bowl assembly. VacuFlush toilets require finding space elsewhere in the boat for the vacuum accumulator tank andvacuum pump or the combination "vacuum generator" and none of 'em are small.As for the low current draw, it's important to understand the distinction between amperage *draw* and amp hours *consumed." The V/Flush DRAWS only 5-6 amps...but the pumpruns for about 45 seconds after each flush, and if the system develops an air leak, it can come on between flushes and even run continuously till somebody notices it. Macerating toiletsequipped with fresh water solenoids *draw* 10-15 amps--2-3 times that of the V/Flush, but only run for 10-15 seconds during each flush, resulting in half the power *consumption* of the V/Flush. And they don't magically turn themselves on for no reason.V/Flush toilets are only available from "Authorized VacuFlush Service Centers" for their full list price of about $1100, and unless installed by "authorized" dealers (average cost: another $1,000-$1500), your warranty is void. Although macerating electric toilets have list prices of anywhere from $700-1100, every one of them is available through discount marine retailersfor an average of 30% less, and you can install any of 'em yourself without voiding your warranty.I certainly wouldn't ever recommend pulling a VacuFlush that's already been installed off any boat...'cuz yes, it does work as advertised (within the limitations described above)...yes, it's trouble-free (within the same limitations)...and it's a no-brainer for landlubber guests and children to use, and yes, they're suitable for use on sailboats. They're everything they claim to be. But so are macerating electric toilets equipped with the fresh water solenoid option...and even a 5 year old can touch a touch pad to activate a timed flush. So I just can't see spending what a VacuFlush costs when you can have everything they offer--and MORE--for 1/3-1/2 the price.
