macerator pumps, Liberty Coach
:eek: This post only after I have climbed under and in my waste water bay.
There is a MAC switch on the dash and a macerator spec sheet in my stack of manuals, BUT I can not find either the pump itself or the discharge valve. According to the literature the pump discharges through a 1" pipe, but I suspect that maybe it really discharges through the 3" main valve. Any Liberty owners that could shed some light? Thanks...Ken & Ellen
Why is it that this topic keeps showing up on most threads?
Anyway, if you haven't used your macerator for awhile, you may find that it spins but doesn't pump. The fix is to put water under pressure through a hose into the pump, turn on the pump and prime it.
Then, turn off the water pressure, take the hose to the dump area, and turn it on.
No need to try to siphon the hose by mouth.
Timing is everything.
Yup Priming is Like Timing...
Our experience has been that it is necessary to reprime the pump to keep it happy...often. As with most things on the camper, lack of use dries seals and rubber gaskets. So, we wind up repriming often.
I noted last spring at a Parliament rally one of their new coaches using the macerator only at a full service site. Kind of a different way of handling waste, as all you need is a garden hose and a 4" fitting.
Now you may know more than you wanted?
Funny You Should Mention Mascerator
I was in need of my pump today because I could not move my coach for other reasons. Never used the pump and I hooke it to a discharge hose and away I went. I burned out near the end so I was satisfied for now. Guess I will call Camping World. Another $160 bucks down the drain, but it saved my life today.
Mine is mounted on the floor in front of the dump controls also. Very easy to replace.
