We have Lavac
heads and have had this problem.
Put a bit of water in the bowl before using, just enough so stuff dosen’t stick. We just run in a a pint of fresh water. Then we get by with 6 pumps +/-.
Thank Peggy for that one.
Thank me. LOL
Fortunately we have 2 heads, urine goes overboard
, other stuff in other head
. Having a single head
is a much bigger problem.
But also one head has a Purasan, which gets the solids. Thus we have a similar issue to you as Purasan requires no more than 6 strokes. But you loose the holding tank. And if you want to flush the system you can run
a couple of cycles with no additional inout and then just pump water through.
Separating urine from solids is huge.
