Kerry - The noise is the one downside of the Vacu-flush system, and that's my one worry about my new system (not installed yet). Your setup sounds kind of weird. I haven't heard of that before either. What they may have been thinking is that that the VF could feed either the LectraSan and discharge overboard, or you could switch to the Microphor to be held aboard temporarily while in a no-discharge zone. I'm not sure about that from your description.
I don't know much about the Microphor system; I looked at their Web site and it says that you periodically add chlorine slugs to treat liquid waste for discharge overboard. It also says that it allows for temporary full retention of liquids, up to 3 days, to be pumped overboard once the boat leaves a no-discharge zone. If you drop the chlorine slugs into the head, I'm not sure how that will react in the LectraSan, which uses an electrical charge to break down the waste. I don't think feeding a LectraSan from a VF is such a good idea. The VF is supposed to be fed with fresh water (don't know if yours is set up that way), and LectraSans require salty water for the electrolytic decomposition to work. There's an optional brine tank and salt water feed that LectraSan sells so their system will work in fresh or brackish water. You mix rock salt with water in the tank and there's a variable valve that you open to mix the brine into the water intake to the head so that the effluent will be salty enough for the LectraSan to work. So if your VF is fed with fresh water and you're not adding salt, the LectraSan won't work right. The other reason that using a VF with a LectraSan is that the LectraSan also requires a minimum volume of salty water (whether drawn from a through-hull or from the brine tank) in each flush to work right, and I don't think a VF uses enough water per flush for the LectraSan to work right. That might explain your extended cycles. You might want to give a call to Marine Sanitation in Seattle and talk to one of their experts.

The Tecma discharging into the Microphor sounds sensible, but keep in mind the limited retention time that Microphor mentions. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "UnifliteWorld" group.
