Changing the master bath toilet out has been on the table for a while now. Doris does not like the Microphor as she has to add water from a jug to complete a flush....TMI. Have rebuilt the sequencing valve when we first got the coach in hopes things would improve she still did not like it at all.
Been looking at the different options on the market nothing really is a drop in replacement or the perfect solution for one reson or another. The Head Hunter that Newell uses does indeed require a 1" supply line in order for the macerator to function properly. Other macerating toilets require 12vdc power and controls mounted on the wall as well as special procedures to use.
We had a new SaniFlush Pro macerating toilet on hand for a bath install in our basement....sold the house before getting around to it. Investigating it's potential use and as luck would have it, found an AC outlet in the cabinet above the toilet that is powered off the inverter. That swayed the deal for SaniFlush.
Wanted to keep things reversible in case we ever want to go back to the Microphor. Capped the airline and stowed it inside the drawer cabinet. Used the 1/2" pex supply line. Cut the 1 1/2" ABS waste line just inside the cabinet and attached a slip joint transition to PVC as the fittings needed were not avaialble in ABS.
I used a black piece of Marine Starboard to cover the cut tiles and mount the SaniFlush toilet using the existing holes. The studs for the new toilet are countersunk screws from the bottom. When locating the toilet had to pay particular attention to the drawer opening interference
The SaniFlush is supposed to have a positive vent i.e when flushing and when the pump turns on. I am using a two phase vent....the existing plumbing during the in-rush of the flush to the macerator housing and the air admittance valve for the pumping phase. Have read that some people have used no venting at all....did not want to try that just yet. That is the reason for the Rube Golberg plumbing arrangement on the left. Made up a trim box to hide everything and try to dampen the sound a bit with some cork on the inside.
Thinking ahead on how we are going to use it on the road....I set the water valve at an easy reach to turn on and off as needed. We may not have to but before departure we will turn the water off and flush the toilet tank to keep down any water sloshing from the tank. The bowl is deep enough there won't be a problem there thus keeping the water seal intact.
The downside, it's noisy and it uses 1.28 gal per flush so the jury is still out on that in real life usage if that is going to matter to us or not given the positive flushing it does.
We had the Saniflush Pro, which is designed to handle a sink and shower, on hand but their current offerings have several other versions with smaller footprints, quieter and more economical water consumption.
