Winterizing a lectrasan

[Dcneuro]

Happy new year to all.

Interested in how others winterize their lectrasan. I use antifreeze, although the company discourages that. I only put two gallons through the system this year, previously i did 3. I really have no idea how much is needed to make it through the system. Also, my boat stays in the water, (NJ), all year, salt water, which never freezes, so this keeps it warmer than if it were on the hard.

Thanks in advance for any input.

1) Flush toilet/Lectrasan several times to clean waste from the unit (important).
2) close seacocks
3) Open removable plug in center of unit.
4) Get one of those portable oil change pumps with the little tube. Stick the little tube thru each side the crosscover cap. There is a lot of water in there. Wear gloves.
5) Replace Cap.

Thoroughly clean and then drain the unit as described in the previous post; or, simply desolve a box of rock salt in a bucket of sea-water and pump that through the unit. As the salt concentration of water increases, the freeze point of the water decreases.

FWIW...

I like that idea! That is a good idea, I never thought of that. I pumped two gallons of antifreeze through the system, usually I do three. I talked to Raritan about it, they said two would be ample. I am going to consult with them on the rock salt idea for newt year! Will post reply from them here.
