Thanks for the insite. My wife decided we need a Jabsco "Quiet Flush" in the master cabin. We will also install a Raritan "PH-II Electric/Manual" in the guest head. You won't like the PHE II. The manual PH II is one of the best manual toilets made...but adding a motor turns it into a very poor excuse for an electric toilet. The motor does nothing but replace the pump handle...it pumps a lot faster and with a lot shorter stroke than pumping manually. That means it takes longer to prime, resulting in increased dry friction wear to the rubber parts in the pump, requiring frequent rebuilds. The faster shorter stroke also causes it to "choke" on flushes that slower more deliberate pumping manually could push through easily. And it's not a matter of deciding to pump manually this time, push the button next time...it requires a bit of doing to disconnect the motor and rever to manual...and vice versa. I can't count the number people I've known who've gotten so fed up with it that they've taken the motor off and put the pump handle back on. So if you think you'll ever need a manual toilet, install a manual toilet. Don't try to have it both ways. And fwiw, the Raritan SeaEra is a FAR more durable reliable electric macerating toilet for less $$ than the Jabsco. Btw...the only electric toilets that are actually quiet are electric toilets designed to use onboard pressurized flush water. A so-called "quiet flush" that uses raw water will NOT be quiet, because contrary to what most people believe, it's not the discharge pump and macerator than make all the noise, it's the raw water intake pump. Do NOT try to solve the problem by connecting any toilet designed to use raw water to your fresh water supply. That cannot be done without risk of polluting your potable water supply with e-coli, damage to the toilet, or both...and every toilet mfr specifically warns against it in their installation instructions. I can't find any conversion system for the Jabsco, but the downstream idea should work fine. No, it won't...'cuz the Lavac is designed completely differently from any other toilets. It cannot be done with a Jabsco or any other piston/cylinder manual toilet. People have tried installing a discharge macerator pump downstream of piston/cylinder manual toilets to "convert" 'em to electric, but it doesn't work...'cuz the macerator pulls 12 gal/minute, which is far more than can be pumped manually and results in repeated fried impellers in the macerator pump. The toilet must also be pumped manually to supply any flush water. So you'd have to pump, turn the macerator pump on for a few seconds...pump some more...turn the pump on again. Or spend half your time mopping up the head and repairing the macerator pump. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/books...ku=90&cat=1304 |

There is one electric vacuum head that can pass a t-shirt, but I think it requires fresh water; Peggie probably knows which one it is. That would be the Headhunter toilets, which are not vacuum toilets, but ultra-pricy mega-yacht toilets. Headhunter demos 'em a boat shows flushing panty hose, loose change, BIC lighters etc. It's also important to remember that while the TOILET may be able to pass all that stuff, if it ends up in the holding tank, how will you get it out of the tank? ![]() -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/books...ku=90&cat=1304 |
