This is a bit of a continuation to another thread I created ~9 months ago where I was looking for a toilet to use at an off-grid property where the water fed to the house is from a water tank where the head of pressure equates to ~5psi to the house. In looking at ways to boost that (pressure boosters mainly), I haven't found a cost effective way to do that and have thus not purchased or installed a toilet to the property. In researching what may work with such limited pressure, I wanted to get thoughts on different systems out there and whether there's an option available here.
House details: water tank fed, 5psi pressure at inlet to toilet, septic system ~20ft from house, 4in drain line, construction ~1982, 10" rough-in
I really, really liked the Glacier Bay vacuum-assist offered through Home Depot but they only make it as a 12" rough-in!
Basically, I want a 10" system that's as-good as that Glacier Bay is purported to be.
System #1: Niagara Stealthflush - Vacuum-assist at 0.8 GpF (MaP rated at 800) - clearing the trapway seems fine but worried about moving waste down the line at only 0.8GpF.
System #2: American Standard Cadet 3 at 1.6 GpF (MaP rated at 1000) - this seems like a really good option... highly rated, but risk in clogs at such a low pressure?
System #3: Fine Fixtures / Swiss Madison Washdowns at 1.6 GpF (no MaP rating) - I like the washdown options and don't mind the "cleanliness" issues so much (multiple flushes, cleaning often... not a bother). Install seems more difficult for a layman and the lack of a MaP rating is strange... am I missing something to these systems?
Appreciate any help the community could offer!
