If you are referring to the wax ring on the toilet base, that is a
static gravity seal and not subject to constant pressure. A filter set-up to AKCA recommendations is also via gravity, not pressure. There is nothing more aggravating that to drain your pond for spring or fall cleanout and find that a leaking bottom drain has saturated the earth with water. With a bottom drain to filter, there is no need for spring or fall drain and clean out of the pond. All muck is pulled into the pre-filter and is removed from there. No need to disturb the fish, plants, beneficial bacteria and fuzz algae. That water then causes the rubber liner to have huge pockets of trapped water that bubble up the liner and cannot be fixed without pulling the entire liner out and pumping the water out of the hole and resealing the drain and fitting the liner again. DO NOT USE BOTTOM DRAINS WITH LINERS The above is Aquascape Mantra. Those of us schooled in koi ponds try our best to inform water garden hobbyists, that the infra-structure recommended in koi ponds, make water gardens all the more low-maintenance. So who do you believe? The marketing rep. or the certified KHA, schooled and tested on AKCA recommended way? ~ jan See my ponds and filter design: www.jjspond.us ~Keep 'em Wet!~ Tri-Cities WA Zone 7a To e-mail see website |
