I'm having to use my travel trailer into the fall and winter while it's tucked in my backyard. I have a cleanout about 50 or 60 feet away.I've always been curious about a macerator kit. When you use one, how do you deal with the remaining water/stuff in the hose after you shut it off?How does it do at or below freezing?

I disconnect the hose from the macerator and lift it head high, walking the raised portion to the opposite end. That empties the hose, but does not rinse it out. I call it good.As far as below freezing, the macerator and hose are in the garage unless I am actively dumping. The garage does not get below freezing. I do not leave them out.

I dump the black tank and then the grey tank. My hose is on a reel that sits near the clean out so I leave that end in the clean out until the hose is reeled back up. That's usually enough as the grey water pushes everything from the black tank through the hose. If worried about any drip, you could just put a cap on the end before reeling it up.The macerator also has a port to run tap water in through it, so you could do that until it runs clear.

It uses city water pressure to shoot up into the tank to "Backflush" (I do not think it's all that effective) but on my RV I used a starignt (not elbowed) version of the one I'll link toAfter the tank was empty and flushed by the other rinser.. I then hooked the hose to teh clear extension/adapter and filled it with water.. Pump running.. Several times to flush the hose.. Then I "Walked" the hose followign the following procedure.Disconnect pump assembly from RVLift high. disconnect hose from Pump. (Stand up hold at chest level)Slowly coil the hose allowing it to drain into the septic system as I walk towared the ground end of the hose. Disconnect and store. In cold weather every dumpIn warm weather Only when breaking camp.

As said above , to clean the left over water in the hose , raise the the hose and walk towards the discharge . I usually rinse the hose before using it to put water in the fresh water tank " just joking ". Harbor Freight sells a one inch hose in 75 foot length that I use ! The larger the discharge hose the better !
